Beautiful enclosure design incorporating multiple devices to make it appear as 1 device. Do you have the 3D files on printables?

Definitely Adafruit blog worthy but they prefer you have a github project page or thingiverse/printables with the file available for open source to publish

A little apathetic sounding, but I can work on that part

[drifting crater]

(update, finally ran out of battery after 3 weeks - I'm happy with this runtime)

[spring pulsar]

That's awesome. How often does it update?

[drifting crater]

Every 20 minutes. Rest of the time ESP32 is deep sleeping

It takes maybe 10 seconds from wakeup from deep sleep to back to deep sleep

[spring pulsar]

Cool. I've been wanting to make something like this to show tasks that need to get done

[clever stone]

I’ve been playing around with (and doing some remixing) of Isaac Chasteau’s 3-Axis Camera Slider.
One of the interesting pieces of the build is a 100% plastic large ring bearing. (its over 125mm diameter)
The ring bearing has 4 3D printed parts - an inner ring, a bearing holder, and an outer ring. It uses 6mm BBs (a few dollars per 1000). When it’s installed in the rest of the camera slider, there is a 3D printed retainer ring.
It needs a bit of sanding and cleanup after printing but the results are impressive.

[north mural]

printables link?

[clever stone]

I’d start here and the drill into the links for GitHub.

[north mural]

Ah didn’t realize it was for a camera rig. Very nice design.

With Christmas practically tomorrow when you’re a person who likes to make gifts, I’ve finished some tiny gameboy type boards to make presents for my two oldest kids

[frosty topaz]

Will it run doom?

[exotic sierra]

I think doom can run on an ESP32-S3 lol

[frosty topaz]

I know, I’m just memeing

It probably would be fun to play doom on those though

Maybe.

[exotic sierra]

it measures 36 x 60 mm

so 1.4" by 2.35" roughly

there will be a 3D printed case too

so it'll probably be over 1.5" x 2.5"

[exotic sierra]

I'm hoping to have the hardware ready early because putting games on it will probably be a bit hard

I'm doing them with no sound because.. well my kids are young and last thing I need is loud beeps and boops lol

[frosty topaz]

I’d probably design a pad for a 3.5mm myself, just in case…

[wide brook]

You made me use the Santa emoji in September, you old madman :P

[exotic sierra]

not a bad idea

[wide brook]

Jokes aside, it's a nice and very unique gift idea

Think they'd be interested in programming them?

[exotic sierra]

my son might be there within the next year or so

teaching him coding might be a good way to get him to learn how to focus on things

[wide brook]

Is focusing on things something you learn? I (obviously) don't remember anymore (and I've obviously never raised a child)

[exotic sierra]

in a way yes? It's complicated tbf

some of it is not really controllable (interest, motivation, etc..)

but you can learn how to be disciplined in a task. Though I don't want to teach electronics and coding in a way that feels like a chore.. that's a great way to kill the spark that he has currently

I mostly want him to enjoy it, to find something he can put energy in and get better at as he gets older. something that will either be a fun hobby or potentially something he can use to provide for himself as he gets older.

Added a speaker

plus a PAM8302 for audio

This will probably be the version I make for my brothers.

[clever stone]

The remixing of the 3-axis camera slider continues. I had it all assembled and then realized, I don't use a traditional camera. I always use my smartphone(s). So I had to extend the "cradle" to handle a smartphone and to deal with the lest being at the very end.
I'm Al's reworking the slider mount to receive the drag chain.

[versed lava]

Good job getting that working - I tried it but didn't have a lot of luck with building the bearing (it worked but was very loud) and ended up buying a pan/tilt off amazon to hack instead.

[clever stone]

@versed lava - a few things probably helped me get a smooth 3D printed ring bearing.

1. My printer is tuned very well now
2. A lot of very light sanding to make the inner, outer, and retainer loops smooth _(especially anywhere the BBs contact
3. A tiny amount of green bicycle grease (the grease also held the BBs during assembly which was super convenient)
   The noise I hear are the servos, not the 3D printed ring bearing.

[versed lava]

Interesting - I have a much nicer 3d printer now and I definitely tried it when my ender 5 wasn't running so hot anymore. How tight are the gears - any rattle when its stopped/started?

[clever stone]

@versed lava the herringbone gears are snug. I did not print the TPU version - just the originals using the same filament as everything else.
All the 3D printed parts are in PETG.

[stark latch]

A 3D-printed lamp made using 16 LEDs controlled by a Trinket, all running off 6V. Base and light bar can swivel, and each elbow can be tightened to lock it in place. Probably should've used brighter LEDS, but it's a decent proof of concept and pretty good reading lamp.

[exotic sierra]

Looks good!

[stark latch]

Thanks! It's not quite as pretty on the inside. Some serious cramming of circuitry in the control unit. 😀

[north mural]

Very nice and compact design. I would recommend fillet corners. Avoid sharp pointed edges for something you’ll be grabbing to turn on/off the lamp a lot. Box edges can be sharp enough to cut you sometimes. The interlocking joints look great.

[stark latch]

Yeah, it could definitely benefit from some design finesse. I designed it on-the-fly, concentrating on function and printability, and not really paying much attention to form or ease of assembly. If I had to do it over again (which I might), I'd fillet the edges, blend the control box into the arm, and make the wire channels accessible. Shoving a pair of 22AWG stranded wires down those tubes was a serious headache. (see https://www.printables.com/model/606181-articulated-dimmable-led-bar-lamp for how convoluted the assembly is) 😄

[north mural]

Great modular design too for easier printing. Well thought out. 👍

[exotic sierra]

I was doing an anxious clean (as you sometimes do when you’re an anxious person) and had an epiphany on how to make the display work on an old project

And it worked

Also thanks @warped siren for the example code you posted to GitHub for the GC9A01 displays

[warped siren]

that's a pretty cool looking little board! what's it for?

[exotic sierra]

The hopes is a hacker kind of watch. I am planning to write some firmware for the Bluetooth chip to talk to the rp2040.

[rose barn]

What features do you hope to add to it?

[exotic sierra]

🤷‍♂️

I mostly want it to sync time over Bluetooth to start

[rose barn]

I’ve seen hacker watches that do IR Blasts for turning TVs off, BLE scans, and came with suspicious warnings to not deauth Wi-Fi, despite not having a deauther by default

Cool stuff

[exotic sierra]

I got my first proof of concept board back for my KeyBoy gameboy emulator. It all works except the up button (might be a connection issue 🤷‍♂️) but overall it’s fun! Currently programmed with a dot chaser game. Might add pong to it as well

What’s interesting is that once the power switch is off, there’s roughly 15 seconds of power left in the capacitors on the power line. Pretty cool

[burnt wyvern]

This is so cool! I have a Gameboy keychain that I originally wanted to fit an ESP32 inside of flashed with a Gameboy emulator, but I'm not very good at circuit design.

How complicated was the assembly? Did you solder everything by hand?

[solemn vector]

Nice! I am also working on a board that will hopefully fit in a Gameboy shell, and host a Raspberry Pi. The project has been on hold, but I will resume soon.

[burnt wyvern]

Wow, that's impressive! That reminds me, I haven't worked on my 3D printable Game Boy shell in quite a long time. This is where I'm at right now, it's mostly 1:1 with the original shell's measurements and uses the original fonts, and is fully compatible with the original DMG-01 game boy parts. The back part is still a work in progress and isn't fully compatible so it's not shown here.

[exotic sierra]

I had assembled with tweezers, placed into solder pasted pads that I pasted with a stencil. I also cooked it in a toaster oven

[burnt wyvern]

Ah, that would probably be much easier than hand soldering. I didn't realize there was the USB C port before I had sent that as well. (Also that the pads on the ESP32-S3 were underneath the module)

[solemn vector]

Pretty cool!

[exotic sierra]

Worked on a case for this prototype

Much easier to play now

I just need to add a hole for the USB cable and make some adjustments to the overall body of it

without access to 3D printing (and getting a little tired of trying to wedge everything into LEGO), what is a frustrated button-box-builder to do?

go "industrial"

swirly-board base, neokey 1x4, 3 OLED (multiplexer), integrates with HomeAssistant and my own stuff over MQTT, uses ToF sensor to change menu options (bottom row only) -- waiting for my next allowance to add a rotor with switch (and neopixel of course) -- powered by a Pi4 with nothing better to do at the moment

[exotic sierra]

pretty cool to see one of these in the wild. It looks really good with all the boards you have attached

What are you using for the different wavelengths, and have you found the data to be helpful?

[crimson egret]

That would be Adafruit's product id 4698, the AS7341 color sensor.

And yes, the data has been helpful. It's already being used to mic the sun patterns for growing corals and orchids.

[slim finch]

That's an awesome application! Thank you! (And ohh I love orchids and plants in general, so that's extra awesome)

They aren't normally cheap - just sometimes you get things for basically nothing when the box is missing stuff or they've been there a long time. Your video helped me identify some of the sensors I couldn't though!

Wore it last night to costume party, though I really need to work on passthrough camera to see out of it better lol. Also the eyes kept crashing for some reason, will get it figured out.

The hair has 18 separate dreadlock strands with 18 separate data lines that I wired myself. This vid is before I got it mounted to the helmet plate part.

[north mural]

I got the same helmet and had the same idea. I think adding some Noods to places will look cool too.

[rustic dove]

Ha cool. I haven't tried noods yet but wanted to maximize flexibility on the wiring while minimizing the power cost (also I'm running at ~16% brightness)

and I already had a bunch of WS2812B 144/m strips that I cut up and soldered

the wiring was tough toward the end, and before this year I had never soldered. been quite the learning experience

the hair is 18 strands, 3 sets (left/right/center) of 6 strands with 5 lights each (total 90 lights), and among each set of 6 I have them in 3x pairs in the velcro and ziptie structure I built together. each pair I joined together for their ground and voltage lines, which then soldered onto a 'copper ring' I made out of copper wire so that all of the strands could have flexible wiring to central ground and power rails, which I covered up with electric tape

[sonic fractal]

Tip for everyone designing a ESP8266 board (this is only for ESP12 as far as i know, other boards may not be like this): in some datasheets and tutorials GPIO2 is shown to be high in some states, this pin unlike EN for example, is not a pull-up and should not be connected to anything. The reason why its high is because its the status led. Which most guides and documents i read didnt even mention

This was me when i removed resistor R3 (GPIO2 pull-up) and the led started working

https://tenor.com/view/big-brain-genius-math-mega-brain-tek-gif-27194141

[lean elbow]

In my bedroom there is no light, and the light switch appears to not be connected to anything. I wanted to be able to control WLED and other devices easily, so I built this box to replace the switch cover plate. Didn't want to mess with mains power so it fits right over the original switch. I used a QT Py ESP32-S2 and a Neopixel driver board, and some arcade buttons modded to use Neopixels. Along with an RPI that I'm using as a local MQTT broker, I can now control the lights in my room easily 😄

[pallid saffron]

I think I may have a thing about blinkenlights (https://en.wikipedia.org/wiki/Blinkenlights) -- actually, i do have a thing 😎

[lean elbow]

Love this! I've long wanted to build a giant panel like the ones in the backgrounds of sci-fi shows that's just hundreds of blinkenlights and various knobs and switches that all maybe do something or maybe are just fun to look at and mess around with.

[pallid saffron]

my main problem is i don't have enough buttons for all the things, so each row has a rotatable menu plus there's a ToF sensor on the top of the swirly board to literally switch menus on the front row (rotates between 3 completely different functions) -- the top row controls HomeAssistant stuff

I did a fun project, with thanks/apologies to the Great Liz Clark. Using this guide:
https://learn.adafruit.com/led-matrix-sports-scoreboard/code-the-scoreboard
and broke it down significantly to just do NFL scores for a week - the week # is passed in settings.toml. If you set this to the current week coming up this weekend (it's now 8), it will show the teams that will be playing (with zero scores).
This is one 64X32 board only.
It builds 2 lists with the scores, using json_stream (which is a little slow), then pops up the teams/scores one at a time, with delay between. The pic just shows one.
I did a clone project of this to scroll the results, but it just don't work well and hard to read...
I really learned (after lotsa trial and error) how to use json_stream. The ESPN data received is huge...
I assume that if I run this on Sunday while games are ongoing, ESPN will real-time update the scores. We'll see. Maybe Liz mentioned this, not sure...

For the Qualia ESP32-S3 controller for RGB-666 TFT displays, here utilizing the 3.2 inch 320x820 with touch.

[proven coral]

The black ABS looks good, but the display would be more prominent if I used another colour. Should be possible to add a speaker (to be an alarm), and environmental sensors. Light sensor would allow the display to be dimmed, for use as an alarm in a bedroom.

[north mural]

The Qualia board and larger displays are gorgeous. Slower at full resolution due to all the pixels but will work great for projects that don't need display updates more than 5fps. Anything with slower changing labels will be nice and big with gorgeous image clarity even with 8-bit indexed bmp's. 👍

2 Pumpkins I did for a work pumpkin contest. Using the Monster M4SK for the LED version and using pingpong ball eyes connected to servos for the mechanical version. Used metrominis for servo control and for the neopixel ring fire effects. Also used powerboost 1000's for lipo power management/charging. I named them "Pixel" and "Servo", the Calabaza brothers! Won "most detailed" and won "best overall"!

Got a link to the design?

[proven coral]

It is on fusion 360, so I could make it publicly available I guess. I generated some renders of the case halves with the Qualia ESP32-S3 board and the 3.2" display with capacitive touch. The front and back faces are 15 degrees off of perpendicular.

[proven coral]

I also have a git hub page... I could put the f3d file and STL files of the parts there. What's the GRA (Generally Regarded As) best practice?

There are a number of planes that interface at acute angles that really shouldn't. I think I'd like to fix that with some fillets, chamfers or other steps before I make the design files public. I am perfectly fine with anyone that can reverse engineer the parts from the currently posted information.

[north mural]

Make a printables account for your STL model projects. Especially if they're to be 3D printed that's the best way to share them.

That is how Adafruit shares their 3D printing project files too. All of their models for learn guide projects are hosted on their printables account.

Hello folks! This is my first time diving into the Adafruit community and my first real maker project. The boo's are run by pico w's and have 3 main modes 1) Angry, 2) Happy, 3) cylon/robot. The controller is also a pico w. I used MQTT protocol and routed network communications through a raspi4 in my packet. I'm considering investing some time in documenting the build and publishing code but not sure how best to approach that or if its worth the time. Hope you like it! Cheers.

[short summit]

Very cool! If you do decide to document it, you could use the Adafruit Learn system's Playground: https://adafruit-playground.com/

[sand grotto]

Definitely appreciate a github place, it allows the raw process to be recreated. Maybe you'd also like to use the https://www.adafruit-playground.com for a Note / guide.
It's basically the adafruit learn system for everybody, no ads or data sharing and free forever! (My little section, all unfinished: https://adafruit-playground.com/u/tyeth ). You could point to the github there too. Also once your happy with it then you could email it over to the newsletter, and/or the 3d printing brothers (maybe featured on Wednesdays show). See how you feel

[north mural]

Playground is gaining traction as a good place to document projects and builds. +1 can recommend.

Wow, glad to see these HACKtablets still making an impact.

[clever stone]

Several months ago I developed a 50mm touch-wheel using just 3 sensors. It was implemented in “C” and made into an I2C device.
Today I implemented an 85mm touch-wheel using 4 touch sensors and written in CircuitPython.
Even without any smoothing, the range-data is very usable.

Can I connect an I2S amplifier to the "Adafruit Qualia ESP32-S3 for RGB-666 Displays"? It isn't mentioned in the learn guide.

i started my new-found hobby 1 year ago -- so here is my current kinetic and LED nightmare (6 servos, 1 stepper, a lot of WS28xx, 2 neokeys, 4 OLED screens, a 14-segment display, a fair amount of technic-like parts)

say hi to the nice folks!!!

[strong storm]

update, here it is in action (video is too long for an embed): https://youtu.be/lKaeGmBOBTc?si=kb8n0HlqhlK7gLqc

there's a Raspberry Pi with python-vlc to play the music and Adafruit_Blinka/CircuitPython to control the Neopixels. I had some issues because python-vlc needs to be run unprivileged and Adafruit_Blinka needs to be run privileged so there are actually two programs, one web server and one which makes requests

[clever stone]

Finished up the #CircuitPython TouchWheel library, example, and documentation. I have also included the KiCAD footprints for a 50mm and 80mm touch wheel with button.

I still have a ways to go but this is generally my new pi 5 desk setup, I still have some hardware to add plus lots of software stuff to do. The monitor and terminal are on a ZigBee switch tied to a aqara fp1 so the monitors/terminal turn on if I spend more than 30 seconds in my room and off with 5 minutes of absence.

Motorized analog potentiometer for a very weird project.
It's running at 20% speed.
At 100% speed it's just slamming the edges instantly.
I have nicknamed this the "Railgun Potentiometer".

Here is also a clip of it, running full speed:

[rose barn]

That's really sweet! I was actually seriously looking at getting one of those until I realized it would just be a microcontroller. having some sort of REPL with commands would be very interesting though 🤔

[pallid saffron]

this in a very real way reminded me of stage/concert lighthing consoles that would "playback" the sliders when it was automated -- now i want 50 of these things, but have zero clue what i'd do with them all 😏

[dark cairn]

well, I needed it since digital pots didn't work on that circuit
They are basically very power hungry digital potentiometers.

[dark cairn]

You could make a diy home automation controller or something, and set the pot remotely or manually

It's excellent for this kind of thing

I made a screensaver for my pi 5 desk setup, it runs when I'm not in the room for 5 minutes and then 5 minutes after that it shuts off the terminal and monitors. My plan is to have multiple screen savers. For now I'm just testing with a button.

[proven coral]

Looks like an I2S amplifier can be added, the link in the final paragraph of the description is to a youtube video where lady ada is showing off the qualia esp32-s3 board with a star trek intro video and playing sound from the video.

[gusty shard]

More "it can be done" than "how to do it". Guess I'll figure it out.

[proven coral]

yeah, I'd love to know how they did it as well.

Looks like the i2s pins can be assigned to any of the IO pins, and there are four pins for SDIO, as well as one or two analog pins, you should be able to use the espressif libraries for initializing it and pass those interface pins as needed.

[gusty shard]

Used the standard black headers this time.

[fathom summit]

Wrote a logging function in C which displays messages on my keyboard's screen 🤓
I can "send" messages with logging(ORIGIN, MSG_LEVEL, message, ...);, which will be filtered out (no-op) if ORIGIN's logging level is set < MSG_LEVEL (ie i can log different pieces of code with different levels)

The message is then formatted with a custom set of specifiers i've come up with (message's text is itself a regular format string, that gets passed thru printf)

• Above the line, using: "[%LL] %M\n" (%LL = level long, %M = message)
• Below, it is using "%LS (%Ts) %M\n" (%LS = level short, %T uptime in seconds) with an empty message for testing
  PS: Changing format at runtime feels rather useless so far, i may remove that option

Playing around with strings (specially like this, to tokenize and format) is always tricky and a bit painful, but the outcome is amazing and playing with screens is fun 🙂

[north mural]

I prefer to hide all my errors and just pass or continue right over them. They're just speedbumps sometimes. 😛

[fathom summit]

All "origins" are now set to ERROR as i now the existing code works (nothing should show up unless a critical problem happens)
For future code additions it will be handy tool 🙂

Yesterday, I posted my ePaper progress - a custom RP2040 design with integrated ePaper raw display.

Truth is the PCB was ordered 5 months ago 😳 I feared it would not work and kept putting off assembling it - “fear of failure” stopped me from even trying.

It can be tough to overcome self doubt. Ultimately, I just had to find little ways to trick myself into working on it.

I first assembled the PCB and focused on the RP2040 functionality because it was familiar. Then I tested the custom touch wheel controller. Finally, I tried the ePaper … for the record, it didn’t work first try 😉 (the FPC that came with the display had top contacts and the installation needed bottom contacts)

[stark latch]

I made a holder for my soldering iron because it's so lightweight, it kept sliding off the bench from the weight of the cord.

[exotic sierra]

I had similar fear of failure for my first epaper design. My mistake was that I wired the FPC connector backwards lol 😂

[exotic sierra]

Can you move this to #events ?

It would be better suited there

[weary night]

Ok, I will delete it here and post again in events

[exotic sierra]

Thanks 😊

[clever stone]

@exotic sierra - my mistake wasn’t far off!

[exotic sierra]

Just for a good laugh, this is how it’s supposed to be

How it ended up

[clever stone]

@exotic sierra - I see the three doors that are part of the driver circuit but I don’t see the mosfet. Whose driver did you emulate?

[exotic sierra]

Mosfet is under the green wire

I copied the one out of the GooDisplays data sheet

[clever stone]

@exotic sierra - OK. Mine doesn’t look too bad in comparison 😜

The driver circuit is the block in the upper left.

I switched diodes, thinking that has my issue, and the replacements were larger than the originals.

[exotic sierra]

Oh you used a partially shielding inductor. I used a chip inductor that was pretty chunky but smaller footprint overall

I do like your placement though, nice and clean

[clever stone]

The bank of caps are so flat they are the same height as the bottom lip of the FPC so the ribbon from the display goes right over them.

[exotic sierra]

That’s really cool how that worked out. Is this for the next challenge coin you’re doing?

[clever stone]

The driver circuit is from the datasheet.

[exotic sierra]

EPD is such a nice low power way to display things

[clever stone]

The ePaper will likely end up on a different project.

[exotic sierra]

Gotcha, still pretty awesome to get it working

[clever stone]

Routing that design is becoming a nightmare.

I will note, I am surprised what CircuitPython synthio can do with a PWM pin 🤔

[exotic sierra]

Yeah, it’s pretty impressive

I want to do a synth project one of these days, like the little touch electric xylophone

I just need to find the time to design it

[clever stone]

Looking at your prototype @exotic sierra, I find it rather funny how the various routing rules for the RP2040 ends up making every board look the same.

[exotic sierra]

Oh yeah, most every RP2040 design I do, looks identical for the core layout

[clever stone]

Everyone’s RP2040 design looks the same 👍🏼

[hardy veldt]

This little environment sensor hub's been running for almost a year now (and uploading externally to adafruit.io and pulling info from Openweathermap), but since then I've gotten into home server stuff so I finally got around to integrating it with MQTT on a central local server and cutting it off from external connections.

Home Assistant pretty much sits in the middle, pulling data from openweathermap (so it's only one API call for all devices instead of per device), publishing pressure data via MQTT for the sensor hub, which publishes its own set of data via MQTT, which can be displayed in Home Assistant or Graphana/via Prometheus.

It's more of an experiment/sidegrade, but this way it doesn't need internet anymore to be useful and I can always VPN into the graphs if I need to see them outside the local network. Also scalable for whatever else sensor projects I might want to do.

My desk now has conversational ai, later on a capacitive touch thingy will control the recording instead of the space bar so I can talk to my ai fren with ease. I plan on adding another touch thingy for voice commands. The way it's coded it will work as long as the terminal isn't doing anything so it will work well with a capacitive touch thing

[pallid saffron]

IT LIES!

[crystal pier]

It has never thought, so...

The voice commands will be similar, hold a pad to record audio, let go to run the program which will then launch things on the terminal and or the other 3 screens.

A project I recently finished: https://www.hackster.io/rhammell/interactive-display-for-finding-wheelchair-accessible-places-6020f1

This interactive display is built using a PyPortal, and shows the locations of wheel-chair accessible places on a map.

The PyPortal makes requests to Geoapify to download a map image, and the Google Places API for data about places, which get plotted on the map.

Users can then touch the map to pull up details for any place.

Made an air quality monitor with a couple of cheap analog displays and some NeoPixels

[near storm]

Trained my dog to “speak” using oversized 3D printed buttons. They’re wired to an ancient Raspberry Pi which is running a Python script using the Blinka library. When a button is pressed, it plays the corresponding .wav recording. The output is split and routed to an amplifier (one upstairs and one downstairs) so she can be heard from anywhere in the house. The cat sometimes starts guarding the buttons when the puppy is being “too talkative” 😂

You can buy re-recordable novelty buttons on Amazon, but they cost $10 a piece, have terrible audio quality, have no volume control, and each one requires a battery. I opted to build my own and should be able to support up to 30 words with a single Pi! (Maybe as many as 81 if I extend the number of GPIOs with a shift register.).

Start a thread with your question(s) if you want to know more. Also, I’m considering showing this off on a live show-and-tell, so let me know if you’d find that interesting

Touchscreen GUI menu for feather weather progressing nicely. Have multiple menu option pages. The left/right arrow buttons go to 3 other pages for content. In total have 8 different pages.

Great stuff, thanks for sharing. I've been creating some UI with DisplayIO and am curious about patterns for paging display/buttons etc.
I feel like there should be some easier methods for group/tile/paging etc.
In a web browser request for instance, you're not required to unload the previously loaded content.
Thaks again

[north mural]

Actually a web browser does unload the previous content, that's how you can see the next webpage. It's just built up in a way to make it easier on web designers. There isn't any of that really built into displayio. They do provide a way to add/remove layers (groups, labels, etc..) fairly easily and that's all you really need. I'm all for making the process easier but layouts are more like html templates that expect you do things in a certain way. I'm not using displayio_layouts so I get to customize the GUI exactly how I want. It's definitely a slower and arduous process but in the end you can make everything appear exactly how you want.

One of the downsides is you must wait for any page to fully load before using the menu because the menu must be the top most foreground layer. Otherwise remove/append would throw errors if things half loaded. The more stuff you have on a page the longer the page load time... similar to a web page I suppose. The best method is to use layer[index#] notation so you can insert/load layers exactly where they should be... I'll be working on improving that.

[lean elbow]

Been working on this escape room puzzle-type-thing for a few weeks using a briefcase I got at the thrift store for 10 bucks, and yesterday got the hardware close to something I would consider final. Now I just have to program this sucker lol.

Other hardware: 2 analog displays, a seven segment display, a 1x4 NeoKeys breakout, an arcade button, a CNC rotary encoder, 8 on/off switches, an electret mic, a PIR sensor, a speaker, two potentiometers, a 3x4 matrix keypad, 10 TRS jacks, and 31 NeoPixels. It also has a 32KB FRAM breakout and an RTC breakout. Powered by a Powerboost 1000c and a big honkin' 10050 mAh LiPo battery.

Big ups to the Adafruit docs and ChatGPT for letting me cosplay as someone who knows python 😄
(christmas tree light WIP using a RP2040 and circuitpython)

[north mural]

Nicely done with asyncio.

[scarlet lagoon]

Thanks, it could definitely use a bit of cleanup, but it seems functional enough (for this year at least)

I also ended up changing up the button code logic up a bit so that instead of triggering on event.pressed, it now instead triggers on event.released, as I decided to add a check for a long press (I found setting a variable on press, and then on release checking to see if the time since was greater than > 0.6s, worked pretty well, but I'm sure there's better ways). I now use the long press to freeze the current animation instead of having my apartment look like I'm hosting a rave 24/7.

(we're not going to talk about the fact that I had written out code for blinking the button LED as a "notification" when a press was registered + on startup/shutdown, but during assembly I forgot to wire the LED to a GPIO, so now it's just always on) 🙃

[proven coral]

I've got a tell... The EYE on NPI from two weeks ago, Lady Ada was talking about the TMC5240, released by the new owner of Trinamic, Analog Devices. I've designed, but not tested, a development board for the chip that includes support for the Single-Wire daisy chain feature, as well as Encoder, End Stops, and Analog input. The PCB is 2.4" by 1.4" with four holes for #5 or M3 mounting screws. The daisy-chain feature is intended to be accomplished with 2x7 right angle pin headers and pin header sockets, but also possible with ribbon cable. There is a 1-wire libary available for the arduino that looks like it works with the ESP 32 chips, and I was thinking that the Qualia ESP32 board, one of the various touch enabled RGB screens that Adafruit is selling, with four or five steppers controlled by the TMC5240 might be an interesting 3d printer controller.

The TMC5240 builds on the silent stepper and sensorless end stop features of the original silent stepper controller. First interesting feature, instead of a step and direction pins as input to the chip, you pass movement commands via SPI or Single-Wire. The Single-Wire interface includes the ability to have a number of these controllers attached to a bus, and even have the devices daisy chained. Second interesting feature, you have encoder inputs to the chip, for closed loop functionality. Third interesting feature, motion control is offloaded to the chip, and this is helped out by the encoder input in the second feature. Fourth interesting feature, there is a 12 bit AD converter (admittedly only 1.25V sense range) included in on the chip that can be polled via the SPI or Single-Wire interface. Logic voltage operates from 2.2 to 5.5, so it can run from a 3.3V board, but also compatible with a 5V system. Motor voltage from 4.5V to 36V.

Now, to apply CC-NC, and upload the files from KiCAD to Github.

The walls come in as you get a higher score. Then the backstop gets closer. Once the backboard comes to about 50%, the outer walls recede, then once they get to their original positions, the backboard just comes closer to the paddle until you die since it becomes basically impossible once the backstop is too close. But that's a win 🙂

Added TFT brightness preference, adding new features every week. Camera doesn't pick up how dim the lowest setting is, can barely see it. Should be good for power savings when on battery power during power outage (hurricane).

Uses @languid nebula circuitpython_slider widget for brightness control. Must have a TFT capable of changing brightness via PWM.

Iterative design is fun

that or im bad at taking measurements, you decide

[upbeat lotus]

Made an enclosuer for the Adafruit Seesaw I2c neopixel driver -- this is the first device I couldn't get to work my 2meter I2C cables -- seems it needs a short cable between the MCU and the seesaw even though a long cable will work then between the seesaw and a sensor + neopixel ring.

[ocean osprey]

Nice, designing your own 3d printed stuff feels awesome

[upbeat lotus]

Yeah, using Fusion 360 and getting better at it but its still annoying when compared to how helpful GPT is haha.

[ocean osprey]

I frankly don't trust gpt, I think its better to learn these skills yourself

[upbeat lotus]

I mean its a huge productivity boost -- I graduated from UIUC with honors in 2008 and I've worked in software web systems since then, and I get way more done now -- its like a hammer, you wouldn't install nails the old way once you understand the hammer -- you can still get hurt by it, but its quite useful.

I would love if the autorouting PCB capabiliteis actually got smart from the modern AI

[ocean osprey]

It's more like a lathe, immensely useful but liable to hurt you badly If you use it without knowing what you are doing, and that's the problem

[upbeat lotus]

Sure, but a tool none the less.

But this isn't the place for this kind of discussion, good on you for learning stuff too though

Adafruit Feather M4 Express + Airlift Featherwing directly to a Matrix Panel. No matrix portal or RGB featherwing required. https://gist.github.com/DJDevon3/7166ebd87c9122e23d8de6d4a2cb605d

Contacts OpenWeatherMap and displays the temperature on the matrix panel. A simple demonstration that you can wire up microcontrollers directly to Hub75 Matrix Panels without needing to purchase a Matrix Portal M4 or Matrix Portal S3.... if you're in a pinch.

I forked the pico-serprog project because neither the stacksmashing repo or another prominent fork I found actually worked fully. It took me a few full days, tried experimenting with pio but could never get that to work right, but discovered neither version implemented all serprog comamnds. So in the one that kind of worked I could backup small packets but not the whole rom. Well I just got it working by implementing commands that tell the flashrom the max limit of read/writes and it then chunks them rather than me trying to chunk them (which never worked).

[lucid bloom]

I got myself something hackable for Christmas. https://www.amazon.com/dp/B0BQ716ZS9 usually $150, I managed to add a mpu9250 and a picam v1.3 instead of the 480p cam it comes with, eventually ill pan tilt the picam. I bought some xh254 wires because thats what the kit uses and it has 2 unused 4 pin ports so I turned them into i2c ports. The goal of this project is to learn ros2.

[ocean osprey]

sounds fun, i built a little rover out of cheap parts with a pant tilt pi camera and that was fun

im actually working on a second revision

[lucid bloom]

The goal is always to have fun and learn stuff 🙂

[ocean osprey]

exactly

case in point, first motor mount

updated stronger mount lol

you can see how i went from a bare minimum design to something with some heft

[lucid bloom]

I think 3d printing is going to come in handy with my robot. I can print a new top side that mounts into the existing holes and will open up a lot of possibilities

[ocean osprey]

exactly

do you have any experience with cad?

[lucid bloom]

I do openscad and that's about it

[ocean osprey]

i mess around with fusion360

designing parts for your robot will definately feel cool

[lucid bloom]

The software the robot comes with is garbage and it's missing parts on GitHub so I decided the only thing I'm using of theirs is the hardware

[ocean osprey]

that seems more fun to me

[lucid bloom]

Definitely it's running ros2 humble

[ocean osprey]

mine is running some rubbish i put together 😄

[lucid bloom]

My previous pi experience has come in handy with the hardware/software so far. I started learning ros2 about a week ago. I can get other people's code running but that's about it, at least for now

[ocean osprey]

for mine the brain for some of it is an esp32 huzzah, then theres a pi for camera, the plan is to make the pi talk to the esp32, maybe?

[lucid bloom]

I don't know what the end goal is, I may end up going beyond the empty slots and replace the sensors in the kit with other sensors

[ocean osprey]

the thing is with somethign like this is you can use it as a platform for all sorts of things

[lucid bloom]

The interesting thing about this kit is it can use 4 different boards

not exacvtly, the bolt blocks the shaft entirely

have shifted the bolt hole, 12 hours of printing and boom ill be sorted...

[last bronze]

Almost repaired

And all ze others

[ocean osprey]

oooo

[main loom]

Such a confidence boost.
The buttons are all wrong, but that's just because I haven't remapped them from the test rig.
But it WORKS

No fancy libraries because I don't have the RAM, juggling raw SPI commands, my first board assembled by the factory, my first time using a boost circuit, and, it worked!

[ocean osprey]

That sounds both cool and terrifying

...what does it do

[main loom]

It's a tabletop gaming counter. Track health, experience, and gold. The code is currently unfinished as I wanted to see if the hardware would actually work right before getting into some of the more interesting functions. What I hope to add right now is the ability to at least save the values to EEPROM as well as optionally pick and choose which stats to track from a small list.

The selection of the ATTiny85 to drive it was partly because I had a few on hand, and partly as an excuse to avoid using premade libraries. That's only a 128x64 display, but it still requires 1KB of RAM for a frame buffer. The 85 has a mere 512 bytes.

Fortunately, if you don't mind directly driving the display, you don't technically need any buffer as the display has its own RAM.

There's also an IO expander under the display as obviously I didn't have enough pins for everything.

[ocean osprey]

Thats cool!

I did programming on the arduboy and thought 1 ish kb ram was constraining

[north mural]

Very nicely done. Congratulations on a successful PCB!

Very impressive using an ATTiny! I can barely do that with a Pico.

[main loom]

The board was almost a failure for at least two reasons. First, I failed to read all the specs that I got for the boost circuit design from TI. At a minimum the inductor is under rated compared to what they specified.
Second, the ATTiny85 spec sheet lists SPI pins, but it's not until you read deep into the spec that you find that they're "backwards". This is because the 85 doesn't have SPI except for programming. So I had to cancel the first order and redo it.

[last bronze]

are you considering adding a brightness controller? It might get annoying during long sessions at night 😛 look cool overall tho!

[main loom]

I'd have to look into the display spec for that, but it would be something to think about for sure.

[spring pulsar]

That is really cool. Are you printing a case for it?

[last bronze]

in theory if the display doesn't have it in spec you could just use dimmer colors in "night mode" or something

[main loom]

Probably no case, the buttons are rather close for that, and the switch is a bit small.

Unfortunately, I didn't pick these colors. It's a 1 bit display. The only reason I get two colors is because the first 16 rows are yellow, the rest are blue.

[last bronze]

I wonder if it could be used as a virtual dice too 😛

[last bronze]

ahhh

[spring pulsar]

I had that same thought about the dice. With a menu button, so many options...

[main loom]

There's a shift button too, currently kind of planning to make it do +/- 10 instead of only 1.

Odds are if I plan for anything like a case, or really advanced options it'll be the second revision where I plan to use the ATTiny1616 instead.

2KB of RAM, proper peripheral support, plenty of IO pins for buttons. Absolute luxury compared.

[last bronze]

I smell a nice tabletop gadget for sale 😛

[spring pulsar]

I've always wanted to build something like this, that I could toggle through games and it would track what I needed for each

[last bronze]

you could make some sort of rfid cards that would trigger certain profiles for each game

[spring pulsar]

I've done some of that with the MacroPad I got

[spring pulsar]

That would be cool

[main loom]

With 512B of EEPROM, it definitely has the space to save multiple games worth of stat settings.

[spring pulsar]

Or a barcode scanner and scan the game

[last bronze]

maybe you could try to make it in the format of a raspberry pi pico HAT

would unlock so much potential

[main loom]

A whole new adventure in programming there. I've never done anything for the Rpi type systems.

[last bronze]

so much fun around the corner 😄

the HAT format would make it easy for people to make at home if you ever publish the schems

whiiiiich could increase the contributor count 😛

[main loom]

Heh.

One thing to note is that the current design uses a preassembled display my coworker gave me that he got on Amazon. So it's just stuck on a female header.

[last bronze]

but for rev 2 I'd suggest using some sort of a usb-charged battery

[main loom]

It would be cool to have the display properly integrated onto the board.

[last bronze]

cause regular AA are kind of inconvenient in these days 😄

[main loom]

Perhaps. I didn't want to really deal with lithium management quite yet.
Though it shouldn't be that hard as long as I'm not trying to do things like solder the batteries directly.

[last bronze]

there are plenty of designs online too

[main loom]

That too. I mean, it's not like I designed the boost circuit I'm using anyway. I just threw numbers at TI's power designer and used that.

Which I'm happy I didn't mess it up too badly. The original spec called for an inductor with 192 mohm resistance, and rated for 1.5A.
The one I used has 600 mohm resistance, and is only rated for 50mA. Oops.
Fortunately the design was only drawing 20mA when I checked with the USB power meter.

[ocean osprey]

Many, many years ago, I worked for a company that made LED matrix signs for the Toronto subway platforms. The LEDs were all red (blue didn't exist yet and green barely worked at all), and the signs were driven by Z80 processors. The refresh rate was pathetic, leading to weird side effects when you wanted to do any animation (e.g. horizontal scrolling would result in the graphics skewing left or right). Love seeing how far the tech has come since then.

Got my LoRa radios working tonight ... not sure why I couldn't get the feather version to talk to one of these but that was also days ago, I should try again now that I got these working together (still need to install the antennas, but wanted to check range without first -- not far).

Unrelated: Earlier today I finished my v1 prototype of this pocket detector project I have been helping to prototype and sending to client in the morning. It uses neopixel 24 rings, seesaw drivers and ADXL acceleromters and an 8-channel mux. The next iteration will not have a centralized MCU or mux -- but rather each detector will be more encapsulated.

[north mural]

feather version on the same frequency? I've mostly been using RFM Featherwings with RP2040 Feathers (before they made the RFM Feather). Those all work well together nicely. Actually haven't tried using the RFM Feather yet or I might have some advice. Project looks like it's going very well!

The pucks look fun to play with. What is a pocket detector?

[upbeat lotus]

Yes same frequency -- put the antenna on last night and its been communicating all night from the kitchen to the upstairs here. Pocket detector like for billards to detect a ball entering the pocket

This is the feather M0 Express

I think I was doing something wrong with these radios last time because I just got the Feather M0 reporting in to the receiver as well.

[north mural]

Fair. I think LadyAda mentioned when they first came out that a dedicated module or featherwing version can perform slightly better than the built in RFM Feather depending on what Feather you use with it. I typically use S3's so that would perform better with a module/featherwing than the RFM Feather RP2040. Since you're using PIco's the performance should be about the same as the RFM Feather. Making good progress.

Pocket detector for a pool table would be a neat way to automate scoring? I honestly don't know much about billiards.

[gaunt spade]

I made my own james webb space telescope!

it cycles through a set of ~100 images taken by the actual space telescope, and displays them on the screen

[north mural]

That is gorgeous. Looks like you put a lot of time and thought into it. Congratulations. It's stunning.

[gaunt spade]

Thank you 😁

[rose barn]

I was under the impression that running radios with an antenna is usually a very bad idea, but perhaps it's different for lower powered ones. Very cool though! I know I was unable to get a nRF52 feather + LoRa radio wing to communicate with others. I think it was a problem with the nRF52 firmware, as switching it to an ESP32 feather made it work almost instaneously.

[upbeat lotus]

From the product sheet:

Our initial tests with default library settings: over 1.2mi/2Km line-of-sight with wire quarter-wave antennas. (With setting tweaking and directional antennas, 20Km is possible).
Adafruit sells matching antennas.

[ocean osprey]

Random tip I got from tested, whiteout/tippex markers will write easily on 3d prints and most surfaces which are fantastic for labelling various features

[north mural]

Keep in mind Adafruit has access to the roof of their building for such tests. If you do it on ground level your line of sight is still literally line of sight. There is almost no scatter. If you want increased range ask your local municipality to lease space on a tower... a roof... or find a really tall tree with good line of sight.

a modelling excersise, modeling the negative space within a hinged joint

otherwise known as "just model the hinge joint and boolean cut the body to get this with less effort"

but it was fun trying to work out what the empty space in a hinge would look like

lets print it and see

[reef flax]

My new years resolution is going well, i finished a project! 😮 My house is modern and has no fire place and I wanted one. So with an old cast iron fireplace from a friend, some scrap wood and some fancy small tiles, I made this. Really pleased how well it came out.

[ocean osprey]

my negative space modelling excersise worked perfectly

used it as a tool to cut hinges into a flexible shaft

And the hole is the exact same size as a 24.5" monitor. 🤔

i was going to ask if you are going to put something in the gap

[reef flax]

Yes, wanted to make it first and be sure it looks good before buying a monitor. That is the next stage. There is a hidden shelf behind the fireplace which has the plugs and my Nintendo switch on. So have some room to play with.

Most importantly the wall behind has not been touched, so easily removed leaving no damage.

I made a little motion activated bird feeder camera! This was a Christmas present for my mom, but I spent a couple weeks finalizing the code and stuff to make sure it could run on it's own without maintenance. It senses when a bird is on the feeder using a PIR motion sensor and takes a couple photos and one video, then uploads them to my Dropbox folder where they can be viewed from anywhere. It also only takes photos from dawn to dusk, so it will only take photos when it's light enough to see the feeder.

Here are some photos and videos taken recently with it, along with some photos of the thing itself:

I need a down-facing camera for streaming and tutorials. I have tried (and DIY’d) many options. The key is to have the camera and the subject matter “linked” so it is always framed correctly.

Now I need the solution to be lightweight and portable so I 3D printed this design.

Have you ever thought it would be cool to have a laser engraved laptop but would never consider laser engraving a laptop?

I bought an Amazon Warehouse shell for my MBP. It has a scratch on the inside (likely why it was a return). The scratch would catch light and be very obvious. This gave me an idea.

I laser etched the inside of the shell. Depending on how the light catches it, it will have a subtle to very obvious effect.

[clever stone]

Not being one who can leave well enough alone … I was noticing how well the Apple logo shown through the shell and thought, “I wonder…”

Battery finally died, not certain it was fully charged when I started.

[lean elbow]

Noe Ruiz showed a WIP of a rotary fidget toy on last week's show. Turns out I've also been working on one, just finished it a bit ago! I wanted this one to double as a WiFi remote so I used a Feather ESP32-S2 and a PropMaker FeatherWing. Also used an ANO rotary encoder (using the non-stemma-qt breakout), a 16-LED ring, and a 400 mAh battery. It automatically goes into deep sleep when you stop interacting with it for 30 seconds, and wakes up whenever any of the 5 buttons are pressed.

[flint sapphire]

Made this as a example for the students in history class at the school I work at to incorporate history class with the maker space.

[elfin sedge]

I’m going to attempt to replace the LED signs on the far left wall with a Matrix Portal S3 driving a 5x5 grid of 5mm 64x32 HUB75 panels. The existing signs are 90’s era made by Alpha that update very slowly via serial using an arcane protocol. An old project of mine that’s served us well for years. It’s time for an upgrade, though.

Version 2 with some improvements over the original: 1) dialed in the LED separator grid yielding a much nicer display, and 2) used a variation on the Ruiz bros trick of powering the LEDs with 3.3 volts, allowing me to remove the PropMaker Featherwing. This also allowed me to make the device a few mm slimmer. An additional "hack" is that since I'm relying on ESP deep sleep instead of a physical switch, I'm powering the LEDs using the stemma qt power, so that when the I2C power pin disables the stemma port at sleep time I get to power off the LEDs "for free".

[ember pendant]

Just put together a travel kit. Soldering iron, solder, 3 different usb cable types, a USB b to c adaptor, jewelers screwdriver kit for game systems, a philips jewelers, a pen a multimeter with header leads, SD card adaptor, screws in m3 I believe, shrink tubes, a solar panel and nail clippers which work as make shift wire strippers (plus you never know when you need to clip a nail. There is an alegator clip but it goes to my custom built iron holder. All fits in a Java cigar box. Might even be able to add a few more thin items like a notebook later

Tins are great

I pack projects in these (these are parts for a hand held emulator I'm building). Stuff into the bottom of a duffle, add the tool kit, pack clothes over.

I'm very proud to have been able to put the tool box together

[solar yew]

good job....all those lil parts, U gotta have a sorting and storage solution

[ember pendant]

All the screws are in the small almonds tin, the game system drivers and the shrink tube are in the other. Everything else is big enough to be placed easily enough

[ocean osprey]

if you decide to enhance your portable kit you can get USB soldering irons that are very small

[zealous eagle]

Well, there are half a dozen things I would change for the next time, but I am super stoked at how well my first try at laser cut design came out!

[ember pendant]

No. Storage only, though I did pop a battery into a tin before. May revisit it and put in the boost

Not going to make it to Show & Tell tonight, but I have updated the project page with some code and setup info.

https://adafruit-playground.com/u/cadet702

[north mural]

You can add more buttons with a multiplexer like a PCA9548 https://www.adafruit.com/product/5626 multiplexers allow you to chain a lot more buttons. you could have 100+ buttons if you want. great playground note updates.

[near storm]

Actually, I've looked into this quite heavily and I could extend the buttons that way, but I'd have to roll my own driver to do debounce and matrix keyboard stuff. If I'm going to do that, I'll just charlieplex the inputs and get 13 * (13 - 1) usable buttons.

If I'm sticking to low-effort-land my options are:

1. Direct wiring (limit 13)
2. Matrix keyboard (limit 7 * 6 = 42)
3. Shift register insanity (no limit, but you need a shift register for every 8 buttons)

I started with 1 (which she has almost out grown). So I'm moving on to 2. If she out grows that (which she might well), I'll just have to buckle down and contribute back to CP 😉

Come to think of it... I should add this info to the article... maybe this weekend...

[north mural]

Are you using Blinka on the Pi? There is a circuit python driver for the multiplexer. As long as you're good with what you've got then doesn't really matter. Imagine you have your hands full just trying to teach a pet 13 different buttons anyway. 🙂

[near storm]

Yup, Blinka. Huh, I'd thought the CircuitPython drivers for GPIO expansion weren't compatible the keyboard library. But now that you mention it, even if they were just individual pins, if I had enough of them I suppose I could still apply the debounce library to them 🤔

[north mural]

Oh you’re using the keyboard library. I’m too used to microcontroller circuit python with digitalio. Most Raspberry Pi stuff is over my head. Ignore me.

[feral orchid]

Ultra cheapo laser power meter using an aliexpress TEC, an INA237 current sensor board (repurposed as a high sensitivity 16 bit differential ADC), and a microcontroller with display (displaying power in mW). I'm not sure these readings are accurate since I don't have a proper calibration source, but they should be around the right value.

[elfin sedge]

Project update on "LEDselector." This is my attempt to make a live updating scoreboard for an indoor RC car track.

First off, a huge shout out to @north mural for sharing his large LED matrix project. I came across it, and once I saw he made the printable brackets available, knew I had to give it a try. He's been helping me with ideas throughout this process and I really appreciate it.

So this is 25 64x32 (5mm) panels mounted together in a 5x5 grid. Things are going well so far. I was surprisingly able to light up all the panels with a single Matrix Portal S3, though only with an error screen. Trying to address all of them as a single screen throws an error. I've opened a CircuitPython bug on it. In the meantime, I'm moving forward driving this with two controllers. Since it's a scoreboard that only displays text, I can easily break it up into sections. And since its data source is MQTT, messages will arrive to both controllers nearly simultaneously. This works for my project. It might not work for others. Something to keep in mind.

Now that it's all wired with power, I can start working on making the code a bit more production ready. So far it's just all PoC stuff. That's next. Will update again soon.

[north mural]

Wonderful power distribution and cable management. It's been a pleasure to watch your project take shape.

[elfin sedge]

I wired every panel with an XT30 connector and then used these adorable power distribution blocks:

https://www.revrobotics.com/rev-31-1293/

[north mural]

Probably also worth mentioning the time and dedication to printing all of those brackets. That alone probably took about 50-60 hours of 3D printing time and multiple entire spools of filament.

I'll look into updating my power distribution. Your method looks much cleaner. Also do you have a link to that 5V 60A power supply? I might get one of those instead of the multiple 5V 20A ones I'm currently using.

[elfin sedge]

https://www.amazon.com/gp/product/B077BP1F4Z

Tons and tons of printable covers and mounting brackes for this PSU out there. Search for LRS-350. All voltages seem to use the same case.

[north mural]

I can design a bracket for it. 😉

[elfin sedge]

I bet! 😄

[elfin sedge]

I burned through my first new roll of filament (Prusament azure blue PLA) and was waiting for the second to arrive. I had an old spool from 2019 that's been sitting out this entire time. Threw it in the filament cooker for 8 hours and printed the rest of the brackets with it without a hiccup.

[stark latch]

Working on a motion-sensor project. Went with a with a fairly utilitarian design (box with a snap lid, a bunch of holes and built-in standoffs). Did a couple of test prints to check board mounting. That Feather is just a stand-in. Will eventually be replaced with an ESP32 V2 w.FL (hopefully arriving today, along with the antenna).

[stark latch]

And here's the result. Just a plain gray box with a snap on lid. Nothing fancy. I've currently got the Feather programmed to act as a wifi access point that serves a single web page with time since the last detected motion and the total time since power-up. When connecting to it using my phone, I got a range of about 300 feet. Ideally, though, I'd want it to connect to the local wifi and report motion. Problem with that is the situations under which I'd want to use it, the wifi usually has a captive portal. Not sure of the best way to handle that, though.

[north mural]

Good job on the enclosure design and print. Looks very clean. Captive portals with IoT sounds like a dilemma especially if it has some type of captcha.

[burnt wyvern]

This would be great, I've had to repair a couple OEM displays on my own by lightly rubbing a soldering iron over the rows of pins so they make contact again. It's a tedious process and in the end I think the sharp displays look much better :)

[solemn vector]

Pretty cool gameboy stuff!

[fervent plover]

It’s amazing you are able to resurrect them! I’ve tried it on the pocket display and I’ve never had success

[burnt wyvern]

Yeah, it's tough. It only really solves the horizontal/vertical lines issue though.

You've done exceptional work on your project. Knocked it out of the park. I congratulated you on your progress in this week's circuit python meeting in the status updates section. There were more than a few developers that were really impressed with your project. You're the first to break the matrix, congratulations Neo, I mean Syndr0me. 🙂 https://www.youtube.com/watch?v=G1wTH6PpfxQ

I've been working on a featherwing adapter for the ST7796S 480x320 TFT display.

[elfin sedge]

Thank you so much. That was a great listen as well! Glad to hear people enjoyed the project. I certainly have!

[pallid saffron]

it's eye-popping, for sure

[marble mantle]

I really like the artwork!

[fervent plover]

Nice! What sorts of refresh rates are you expecting?

[north mural]

It's a SPI display so will be limited to the same refresh rates in circuit python as any other display of its same size (3.5" TFT Featherwing). There's nothing special about the display was merely an attempt to create my own TFT Featherwing replacement at a time when the TFT Featherwing was out of stock for about a year. Now that the TFT Featherwing is back in stock it's just a personal project that I want to finish instead of having it in my mindspace as an unfinished project.

Also I started a project with it that requires that displays mounting holes and the TFT Featherwing is a different size. Instead of 3D printing a different elaborate mounting system to finish the project I'll need to make use of the hardware I started the project with.

Supposed to be a birthday gift for someone in August. Last August. 😅 To say I've procrastinated on it is an understatement.

[fervent plover]

Sounds fun! I’m sure whomever it’s for will be pumped

[vagrant torrent]

Not gonna lie, this looks like a giant hand wired keyboard.

[elfin sedge]

I really like the blue brackets on black panels. It started that way because it's the only filament I had on hand.

I’m thinking about writing a series of project guides called “look ma, no microcontroller!” on Adafruit Playground. The idea is to show the kinds of electronics projects you can do even without a processor. Like, dimming LEDs, RGB LEDs, variable power supply. Would this be of interest to you? 👍,🤷‍♂️, or 🥱

[vagrant torrent]

What qualifies as a microcontroller? I suppose ASIC chips don't count? Is a 555 a microcontroller?

[ocean osprey]

It might be interesting to some people but frankly idk if its something i personally would bother with, chances are if im making a project and i can just throw a microcontroller at it that is what im going to do

[ocean osprey]

THOUGH admittedly i have considered learning more regular analog electronics

[near storm]

Yes, that is the question. I was planning to focus on anything that doesn’t execute traditional assembly instructions. So, 555 are valid, EEPROM finite state machines, op-amps for stable control, etc

[lucid bloom]

I had some issues with my soldering but I managed to get it all happy and working through some trial and error. I can get the drone to arm and the motors work/spin properly so I am getting rather close to flying it. It took longer than expected, I stopped worrying about getting it wrong and focused on just getting it done with the least number of mishaps. I sliced a power wire, screwed up the GPS soldering, mashed a pin on the vtx, none of which were fatal errors.

[dawn coral]

Made this guy for the kids. Modified it with a DFPlayer and tilt switch. Needed to use an npn transistor to trigger the dio play pin (was too lazy to look up any open uarts on the tiny project MCU). Video with the audio on a timer, selection to use debounced tilt switch instead (each kid wanted a different setup) - https://learn.adafruit.com/terrako/overview

[north mural]

Always a good feeling when you get something working. Is that a ublox GPS module below the antenna? How well does the video feed work? The little FPV camera I got for my RC car is kinda bad and full of static but it was only like $40. It's hard to find a good FPV camera setup without spending hundreds on something DJI related.

[north mural]

Those are adorable. I don't play Zelda so I don't get the reference. They remind me a cute mashup of R2D2 and a Dalek with tentacles. 🙂

[lucid bloom]

Yes that is ublox GPS, the video seems to work ok except I haven't range tested it. I took it apart too many times and now the mashed pin on the vtx is a missing pin so I ordered another one. I tried to keep costs down otherwise I would have gone digital. The GPS doesn't seem to like being next to the xt60 so I modified the nose design to have a surface to mount the gps to.

[dawn coral]

Pretty much lol I do have a few gripes with the overall CAD design though. The major problem is that the bottom plate where it holds on the legs blocks a USB cable from fitting into the charger port, I could not plug in a cable to charge it without popping the base off the bottom which is not a good solution long-term. Retention for the legs is pretty poor as well, they fall off very easily. The servo horn mounting plate could very easily have been made significantly more sturdy, probably the weakest point of the build.

I'll have to see if I can get the step files from the design and make some adjustments, at least the base plate is easy to change

I might just run a drill bit through each of the legs and put a string all the way through to hold them on

[north mural]

The easiest way to make a hole or enlarge a port is with a soldering iron. As long as you have a sponge and brass tip cleaner you can clean the tip after using it to melt plastic.

[dawn coral]

I have a Bridgeport..... Lol

And a drill press

There's no hole currently, it's a snap in ball retainer but it's too loose and comes out

The walls are too thick for a decent amount of flex too, so from a design standpoint it's either not going to fit or will easily fall out... Needs a secondary retainer... Considered a slip ring retainer but it wouldn't look good

[lean elbow]

Shoutout to @north mural for the suggestion to use mirror tint film to better hide the unlit segments of a seven segment display. It looks better in person but even photographed it's a lot more readable!

[dawn coral]

I would love to modify the original CAD, but the edit design link on the Ada fruit project page is dead

[glad roost]

could you point to the page with the dead link?

[dawn coral]

https://learn.adafruit.com/terrako/3d-printing

[dawn coral]

this one, the edit design goes to a dead f360 project

[glad roost]

Oh, that's too bad. I'll tell the authors.

[dawn coral]

If they have it somewhere it'd be great to get back up

And if they want info on how I did the audio, I can pass it along too

[glad roost]

I sent them an email - thanks

audio sounds neat

[wicked horizon]

hi folks we updated the link for terrako: https://a360.co/3w56fLD
we had to update our part directories and lot of project share links changed 🤦‍♂️

[dawn coral]

Woohoo!!

[glad roost]

@dawn coral 👆

[dawn coral]

@wicked horizon thanks, see the notes above on the changes I'd like to look at making?

[dawn coral]

This

[wicked horizon]

ah yea it was designed to fit the one we have here

[dawn coral]

I went through 5 cords to find one I could cram in there lol

All of em caught on the leg retainer

[wicked horizon]

ah yea you can totally measure to fit the cable you have the most of

[dawn coral]

I'll probably pull the base out too, give some more wire room, flat bottom for printability

Kids love it

[north mural]

You could cut 2 pieces to add more diffusion. Looks great though. Much more readable without the unlit segments being more pronounced.

[lean elbow]

@north mural I think that's an artifact of photographing it, IRL I can't see the segments 😄

[north mural]

Yup, took a couple pictures before I figured out how to capture the mirror reflectivity just right. Using the cutting mat with the grid reflected made the effect more obvious.

[lean elbow]

I just find photographing LEDs in general pretty difficult, at least with the only camera I have available to me on my phone lol

[dawn coral]

Do you want the info on the audio I added btw? Not sure if you want to include non Ada fruit parts, or redo it around the audio boards on the site

Didn't see a standalone MP3 board, just wav/ogg with onboard flash which isn't bad but much larger than what I used (DFPlayer mini)

https://a.co/d/fHjhf7X this, a microSD card and a 2904 transistor

[north mural]

Since it uses an Adafruit ItsyBitsy as the main board and most of the products are Adafruit it's ok to include links to other manufacturers parts. Attempting to substitute an Adafruit part that you don't actually use in the guide would be a bad idea as you can't ensure any included schematics will work without testing. There's plenty of precedence for this is many other Adafruit learn guides.

[dawn coral]

Yeah, I just added to it, only sub I made was the rgb neo pixel ring was out of stuck so I got rgbw lol

[north mural]

If you want to attempt to amend the Learn Guide to use an Adafruit MP3 player you could purchase and try testing it with one of the wave shield MP3 boards. https://www.adafruit.com/search?q=mp3

[dawn coral]

I looked a while back, and they were massive in comparison

[north mural]

That's not always possible since the Arduino Uno format is much larger than an ItsyBitsy and might not fit into the enclosure.

yep

[dawn coral]

I don't recall anything I could physically fit

Even the featherwing is exponentially bigger

[north mural]

A feather or featherwing would be the smallest as an adafruit part. Otherwise you would end up having to go elsewhere and that's ok.

If a part doesn't exist for the size you need then there's no way to keep it all Adafruit parts. So Adafruit might want to think about creating it so in the future your guide and others could use an all Adafruit lineup of parts.

You could shoot them an email they do take product/stocking suggestions.

[dawn coral]

Easy enough just not sure how much interest there might be lol

[north mural]

You might be surprised. There are plenty of people who actually prefer the ItsyBitsy form factor.

[dawn coral]

Yeah... Usually not messing with stuff that small lol this is actually the first non work related thing I've built in a long time lol I always forget how much of this stuff "regular" people use 🤣

I'll just keep my 208 pin MCU project over there .... Lol

DeLorean time circuit display vibes

[north mural]

Featherwing adapter PCB's came in today. Fit like a glove first attempt.

[north mural]

One thing I learned during the chip shortage is not to rely on one distributor... and that even applies to Adafruit. The TFT Featherwing is my favorite display for circuit python displayio projects but they were out of stock for more than a year. So I set out to find a comparable display and made my own. This increases my options if I need another 480x320 SPI TFT in the future. It's not as slim as a TFT Featherwing but otherwise can act as a good replacement.

[lean elbow]

The Ruiz brothers highlighted my version of the rotary fidget toy project today on 3D Hangouts and I realized that I never shared any of the technical details for it or any of the updates I made after the initial post. I was able to remove the Propmaker Featherwing completely and just use the naked Feather boards, and I wrote custom Arduino code for the project. I'm going to spend some time in the next few days working on making a CircuitPython version to share (and a subsequent playground post) that should be easily adaptable to the Ruiz brothers' build, but in the meantime I thought I'd share the prints for it (and some inscrutable text/instructions in there about how you can choose to use a Feather RP2040 or an ESP32-S2/S3 and some other rambling 😂) https://www.printables.com/model/733974-ano-led-fidget-toy

I'm going to attempt to parlay the obvious Simon inspiration into a version of the game as well

we turned a ceramic glow plug into a open source 1300 C hotend for printing metal and ceramic on the home desktop.

still needs a lot of testing and tuning, but we ay have test prints very soon.

[north mural]

If you thought 300C was dangerous for home hobbyists wait until you see 1300C. 🔥 I'm amazed the hotend doesn't melt all the plastic parts around it like the fans and housing. This could be an interesting new method for homemade PCB's. I enjoyed the friction spindle idea too. Be safe you guys, the concepts you are working on are a bit dangerous but it seems as if you're taking a scientific approach to it. Wear safety goggles. I can imagine clearing a metal clog wouldn't be a trivial issue to deal with. For metal you're likely to require a much larger and longer hotend, heat creep will be an issue if you attempt to use a short hotend with metal that was designed for plastic filament. Tip my hat to you for exploring very interesting concepts.

Oh it's an awesome platform. Although, I really wish it was 5x5...

[hoary compass]

I turned my 8x8 neotrellis into an electronic chess board. Still need to figure out how to program beyond "cut color > paste color" but you can play most of a chess game. No pawn upgrading yet lol, need to figure out how to program long presses to do what I want without affecting the short presses.

[lean elbow]

That's a rad idea!

[hoary compass]

Thank you! I had to prompt chatgpt for the code to get this far since I know very little programming.

Also soldering the 8x8 neotrellis together was very daunting so I'm proud I managed that much xD

[normal orchid]

On each press note the time. Perform actions on button release, or on the time threshold of the start of a long press. I'd make a button state list to track the held buttons, or all of them, then you can debounce if desired.

Just pulled the trigger on 2 PCB designs. ST7796S Featherwing & ST7796S QT Py BFF. Since learning about SPI bus sharing was able to fit a built-in SD Card, TFT, and TFT touch controller using only 7 pins. Since it used such few pins that lead me to try to make it work with a QT Py and was able to fit it and have 4 spare pins left.

Oh cool, thanks for sharing! I’ll check it out, I’d like to help or inspire others to do similar projects. And thanks again for the quick fix a few weeks ago, it was nice being unblocked so quickly. 🙂

[glad roost]

it's nice to be able to fix a bug quickly 🙂

you could also go on Show & Tell on Wednesdays 7:30 Eastern time, but a write-up is for posterity and is searchable!

It’s like 5mm pitch matrix panels had a baby. 2.5mm panels are adorably small and still have the same amount of pixels. Will be working on designing 3D printed brackets since it seems many people liked my 5mm bracket designs.

[spring pulsar]

I just thought you had really big hands...

[north mural]

5mm vs 2.5mm

Photoshopping hands to make the panels appear bigger or smaller is something a marketing dept would do. This is a real size comparison.

I figured if I'm going to continue to add to my 5mm matrix I'm either going to need a much bigger wall, or completely switch to 2.5mm.

[carmine lagoon]

Hello here, making nice progress on my open-source pocket groovebox: https://youtu.be/GBRBZO4gkvU
I thought I'd show it here since the watching the AdaFruit community helped me a lot in my hardware design journey 🤗

[carmine lagoon]

May I ask what people here think about the name "Wee Noise Makers"?

[north mural]

With the video as context nothing wrong with the name. Without context especially in the U.K. it might be confused for something else. 😅

[sand grotto]

Wee up north (uk) means small, a Wee baby, which is nice and endearing. Also evokes thoughts of fun sounds made with voice. Not sure if other connotations would put some off.

[carmine lagoon]

Thanks 👍

[pallid saffron]

sometimes in the US, "wee" is used as a euphemism for urination, especially for small children (my parents were teachers so i skipped straight to "bathroom")

[sand grotto]

here too 🟡

[north mural]

With that said no one really made of fun of the Nintendo Wii for the name in that regard even though they sound the same.

[sand grotto]

definitely a few giggles here, but mostly overshadowed by people hurling the wii nunchuck through the tv playing tennis (not using wrist strap)

[north mural]

I mean you could probably name a device 💩 and kids would love that because it would make their parents eyes roll.

I built a 3D printed 6-axis robotic arm using the Feather M0 and Feather M4 and RFM69 feather wings. The project is on Printables for anyone interested in building it themselves. The Printables page includes a Reddit link to see it running as well as the code, and assembly manual. Printables link: https://www.printables.com/model/742414-6-axis-robotic-arm

[cosmic mulch]

Props for two things: 1. The robotic arm and 2. Your username based on one of my favorite movies.

[queen veldt]

Hahaha thank you!

[cosmic mulch]

Twist it upside down and you can mimic the chair that Lawrence Fishburne sat in. 😆

[queen veldt]

Lol I see it! I'll have to beef it up a bit for that

[cosmic mulch]

How long did it take you to build it (after printing out the parts) ?

I'm intrigued by this, but want to know how much time I would possibly have to set aside to build it myself.

[queen veldt]

With or without procrastination? Lol I worked on this project for a little over 2 years, a mix between having to do a major redesign, as well as me moving slowed me down quite a bit. The total print time though it probably under a week if you print continuously

[cosmic mulch]

Sorry, I meant 'build' as in 'assembling' it.

[queen veldt]

I'd say it could take 2-3 weeks depending on how much time you have available to you

[cosmic mulch]

Well, that tells me it's definitely not a simple "slap together with spit and chewing gum" project, but a proper one. I like that.

[queen veldt]

It's mostly print time, wiring, and the heated inserts that take the most time

Depending on skill level it might be quicker for you. I'm a noob with electronics and soldering and stuff

[cosmic mulch]

It's an awesome looking robotic arm, and I'm also half-tempted to build a GLaDOS head for it, too. 😆

[queen veldt]

It's hard for me to gauge right, cus it took me a lot learning the gearing, and troubleshooting all the code and stuff. But all of that is done now, so it should be much faster. Just hard for me to estimate

[cosmic mulch]

That thing does not scream "noob with electronics and soldering". It screams professionalism, with good attention to detail.

[queen veldt]

Thank you, I tried really hard so I appreciate the kind words!

[cosmic mulch]

Any particular type of filament you used for the plastic in your 3D printer? Like, one being stronger over another?

I'm not sure how heavy those motors are, and if any strain could be put on everything else if one filament is better than another.

[queen veldt]

Most of the arm is PETG, the ring and sun gears are PA6-CF, and the planet gears are PC Blend

I was mostly concerned with the strength of the gearing, and even then my choices may be overkill. PETG is definitely strong enough for the rest though

[cosmic mulch]

I think overkill is better, because you never know if you might do upgrades to it later on and it'll require that kind of strength.

[queen veldt]

Exactly, that's a good point

[cosmic mulch]

Regarding your soldering, did you use any of these to help simplify the process?
https://www.amazon.com/Connectors-Sopoby-Waterproof-Electrical-Automotive/dp/B0BKSJQC9Q

[queen veldt]

Funny, I just used those the other day for the first time. They work great! I didn't get to use them on this project though

[cosmic mulch]

They're my go-to in my electrical toolbox when I have to do wiring on my cars.

[queen veldt]

I'll have to grab some, I gotta bump my connector stash up

[cosmic mulch]

Not sure what you use for soldering and heat gun usage, but I recommend these if you need something portable:
https://www.amazon.com/Dremel-2000-01-Precision-Butane-Soldering/dp/B00MJW08JK

https://www.amazon.com/Dremel-2200-01-Versa-Multi-Function-Butane/dp/B00MJW07Z0

[queen veldt]

I didn't know Dremel made torches, that's sick haha

[cosmic mulch]

Mainly what I use with those butt connectors, is why I mentioned them. Because of their smaller size, the torch's curve attachment is well suited for them; versus my heat gun which has a much wider nozzle, and can risk heating up more of the wire insulation than I want.

The Dremel soldering gun is my favorite for when I have to get into tight spaces, or areas where a long extension cord would be a pain.

[queen veldt]

Yeah I was using a normal heat gun and the results varied. I think the tighter heat concentration of the torch would give better results

[cosmic mulch]

It has, in my experience. When I used a normal heat gun, I risked melting or over-heating the solder inside the connectors.

[queen veldt]

I'll keep that dremel in mind, thanks for the tip!

[cosmic mulch]

Not a problem, happy to help!

[analog nymph]

I have a Hantek 6022 PC connected scope and I did a mod I found on the Internet to add AC coupling to the scope. I chose to do a surface mount homemade PCB for the mod. Here’s a picture and a screenshot of a 40 kHz, 10 mV sine wave with a 5V DC offset being captured in AC coupled mode.

[wide star]

I made this LED focused development board called the LED Mango. The key innovation is that you can solder addressable LED strips directly onto the LED Mango! No more torn wires and messy projects. The LED Mango features an ESP32-C3-MINI, Stemma QT for sensors, and GPIO pin headers. It's designed for 5V addressable LED strips like Dotstar, Neopixel, APA102, WS2812, WS2812B, and more. It comes with WiFI + Bluetooth, and it's matter-compatible. Perfect for home automation + a wide variety of other projects. It has a USB-C port and a barrel jack to make powering your projects easy. I would appreciate feedback from the community here! Thanks! It's also be happy to share this on the Adafruit show and tell.

I just released a new version of my AnimatedGIF library which adds new features and increases the speed of decoding. The 2 major new features are that I added a 'Turbo' mode which can greatly accelerate decoding speed in exchange for using more RAM. The second feature is "COOKED" pixel output which simplifies your code by doing the pixel merging and disposing for you.
https://youtu.be/s8Ks_uhR1qQ

Just updating your projects with the latest version will improve the decoding speed by 5-10% without making any changes to your code.

Reminds me of the "breathing" LED on old macbooks. Very cool effect. Was it just a matter of using a really thin wall to make it show through like that?

[dire axle]

Yup more or less, I used Galaxy Black filament and made the wall 0.4mm, then I printed a diffuser in white filament which is another 0.4 mm so the individual neopixels wouldn’t show up

Awesome, thanks! Excited to try this.

huh, i think CircuitPython should handle 12-bit just fine? that’s a bit depth of 4, and the Learn guide suggests 6. i don’t have any ARM boards working with the panel yet: i need level shifters @north mural

Oh I thought it meant a bit depth of 12. 😬 sorry! ok now i'd like to see how it performs on a bit-depth of 6.

[gleaming adder]

Hey Squid, I'm trying to reproduce your helldivers-2.py setup, and for somereason I'm not seeing it pop-up as a page on my macropad. What libs are on your pad?

[lean elbow]

That's odd 🤔 Unfortunately I'm traveling at the moment and don't have physical access to the macropad, but if I recall correctly I just used the project bundle from https://learn.adafruit.com/macropad-hotkeys/project-code and then added the helldivers-2.py source file to the /macros directory. Also since I'm only using the pad for helldivers I removed all of the other .py files from the /macros folder so that helldiveres-2.py was the only one in there, but tbh that shouldn't be necessary

Also I'm pretty sure I used CircuitPython 8, so I would have used the libs from that directory in the bundle

Ah I might have an idea what your problem is. I'm wondering if there's an error in my code that's causing it not to compile, and that's why it's not showing up

I bet the issue is this line:

START_INPUT = Keycode.CTRL

Should be:

START_INPUT = Keycode.CONTROL

I'll fix the code on my playground page. I actually have my own keyboard remapped to be more like MacOS so my control key is mapped to ALT (so in my personal code I actually use Keycode.ALT), which is why I didn't catch the silly error. Let me know if that fixes it for you please!

[gleaming adder]

Yep, yout right! Keycode.CONTROL instead CTRL fixed it

Thanks a ton!

[lean elbow]

Sure thing! Glad that fixed it 😄

[dark cairn]

Made a module to easily make tty terminalio objects. It also supports injecting other console-compatible objects into it for input.
This way by making a keypad input-only console object and combining the two we have modular display controls.

And then since it's a console object it can be plugged into jcurses for terminal applications.

So here is my DX32A board finished, it looks neat and it accomplishes its goal of being a breadboard compatible S3 board, but im not satisfied with this unit in particular, its unstable and disconnects constantly, however... most importantly of all, it werks

Hot wheels delorean for scale

[sonic fractal]

also wifi do werk

[north mural]

There's a new DeLorean?!?! I had no idea. It looks gorgeous! Glad they kept the gull wing.

What's the issue with the disonnects? Looks like a module so shouldn't be any different from any other S3 module board. :/

[sonic fractal]

yuh, the delorean alpha5, its an ev and they made a collab with hot wheels as a promotion, personally i like it however i think it could have been done better, i think the front should have had 4 headlights like the original instead of 2

[sonic fractal]

honestly no idea but i noticed it happens with my other generic s3 board

with circuitpython, starting up it connects, disconnects, and then reconnects as a storage device

both boards do this, so it seems to be normal behabiour

unlike the generic one, the one i made takes a couple of seconds to be decetced

and sometimes if i move or touch the board it disconnects

which may be a thing with the usb cable/port

what surprised me is how much the S3 heats up, average running temperature is about 40C°

ill try arduino firmware instead to see if the disconnects keep happening

[north mural]

sounds like usb wake or a dodgy usb connection. yes the S3 can get quite hot. the QT Py ESP32-S3 in particular because it's on a smaller pcb. thermal design with the S3 is important.

[sonic fractal]

ill look up usb wake, a dodgy usb connection is very possible since i feel like it worsened after using the hot plate to reflow a capacitor, and about the thermal design, why dont they add a heat transfer pad to the rf shield?? they could use it as a heatsink, wasted potential, maybe ill do it myself for a future design

unfortunately a heatsink wouldnt fit on a qt py

[north mural]

sure it will, you can get heatsinks as small as 6mmx6mm

i just got a pack of them for an "obviously not UL certified" board i purchased that gets to 76C. though i have a feeling it won't do the job experimenting with heatsink sizes is part of thermal design.

[sonic fractal]

i mean it will fit however you wont be able to use it on a breadboard since the soc goes on the bottom of the qtpy, thats what i meant

[north mural]

ah yeah and that would make your breadboard quite toasty too

[sonic fractal]

This will do 👌

[north mural]

yeah honestly i was thinking of 3D printing an enclosure with a little active fan too. the problem is if the fan is powered by the board then it might just get hotter. 😛

[sonic fractal]

hmm

yeah

heatsinks and fans, one of those weekends.

Only issue I had was the bitmaps needed to be converted to something different to not get error messages on the PI in OnDiskBitmap load. Using PIL image.convert
Forgot to mention blinka is AWE-SOME!
