This is the Rick Flash, it's an SSD that Rick Rolls you over a piezo buzzer when you turn on your computer and also creates a WiFi hotspot called Free WiFi! When connected it redirects you to a captive portal with a gif of rick Astley. You can also trigger the song to play from your phone in the WiFi captive portal. https://youtu.be/qJRm4iVWZss.

@normal vale I really like your balloon pressure example that is in the newsletter this week. That is such a great hands on way to illustrate the usage of the pressure sensor!
normal vale
@sharp comet Except for the fight to inflate the balloon and "close" it, it was really easy to do. My plan now is to use the balloon as an input device where you would shake to activate, squeeze to change the volume or whatever. I also tried with the two CR2032 battery pack from Adafruit, it is almost the same size as the Feather. So it was totally wireless. The problem with balloon like the one I use is that they loose tightness and the air somehow escape. But if I had something more durable where an Feather Sense could be embeded and remotly charged... that would be really great fun.

Then use a big balloon and fill it with helium, and add a ballast pump...

I built myself a hybrid between a programmer, prototyping board, and a bread board using two Atmel DIP-28 sockets. Compatible with the Atmega8A and the Atmega328A, both of which I found for cheap at a local electronics store. The LEDs (by default arranged for use in the ArduinoISP sketch) are all capable of being jumpered in/out, as are the trimpots and the capacitor that's connected between Reset and GND (when the center chip programs the left chip). The top row is a do whatever area to connect breadboard friendly modules to. The i2c pins and the Vcc/Gnd pins are both extended out to connect more devices. There's three rows of connected headers meant for use in whatever experiments need multiple things connected to one thing. Built the basic skeleton a week ago and then gradually added more stuff while I had to monkey with some Atmega8As and I found the Uno to be a rather poor learning platform (because I wanted things at 3.3v and using the internal oscillator).
I'm rather proud of the fact that I was spectacularly rubbish at soldering when I started venturing out into electronics a few months ago but I've gotten pretty good at tight connections now π
Here's one that ended up having to be junked because I tried to do all the soldering UNDERNEATH. I melt more plastic than solder and destroyed my tip in the process.

I occasionally have problems with my whole computer locking up while debugging low level circuitpython problems
I'm going to connect the circuitpython board to a pi zero so I don't curse quite as loud if it locks up due to a misbehaving USB device
since I use Linux on my desktop as well, I can share files and the serial terminal over the network (sshfs and screen)
dunno how well it's going to work out in practice yet, but the setup & scripting are done!

Nice! I was just thinking about the idea of setting up a dedicated pi as a Circuit Python building machine so I can stop using a VM since I haven't made the jump to Linux yet. I really like the way you added a little screen and interface for controlling it.
ancient skiff
My plan is still to build CircuitPython on my Linux desktop, I suspect it would be quite a bit slower particularly on the pi zero.
but jerryn I think has done it on the raspbery pi. There's some difficulty getting the matching compiler installed, you should ask him.
sharp comet
He has graciously shared the compiler with me already π. It does take a few minutes to build on the pi. I picked up a Pi 4 but haven't done much with it yet I may give it a try on there to see if it's any faster. It's not much slower than building inside the VM though, and I'll be happy to free up some of the resources it's taking on this PC.

This is what I call my 21st century food pantry project. A contactless number dispenser that also does sms. If a client has a smartphone they can place their own order otherwise they get a paper number and a volunteer fills it out. Led number sign to show now serving number, if they have a phone they get a txt back when it's their number. Orders get displayed in the packing room where I help pack the orders. Been using it for 3 weeks so far, hoping to find time to demo it on show and tell. Basically I took our existing process and made it as paperless as possible. One of the nice things that will come out of this system is I will be able to quantify everything we give out.

Yeah I guess. This pot also has direction contacts integrated (2xNO contacts, one closes at about 45% and the other at 55%). I used to yellow 3mm LEDs for them.

Hi everyone! I'm new here so hopefully I'm doing everything correctly π. I've been working on a crazy personal project for about a year now. It's a custom Arduino smartwatch. I just finished version two and here's some photos of it as well as a comparison to version 1. Version 2 is powered by a Adafruit Feather sense (one with built in bluetooth). I was able to make v.2 alot thinner because I ditched the use of a RTC and instead went for a Bluetooth LE CTS approach. Because of that, battery life increased from 4-6 hours all the way up to 30-36 hours roughly. Now the one problem I faced with that was that I don't use an iPhone (I have an iPad to sync time), so I coded it so it would keep track of time even when disconnected from Bluetooth. I also created a port so anyone with an Adafruit Clue can test it out using the Arduino IDE. Here's a link to the Clue code: https://tinyurl.com/y5aawc3x
The watches were 3D Printed using a PRUSA mk3s (PLA filament) that my university has. It was designed using TinkerCad. Also, any 22mm watch band would be compatible π The 16 NeoPixel LED Ring emulates the hands on a real watch (red is hour and light blue is minute).

@grizzled talon Nice project, I am interested in the CLUE side of your project. I have hardware with only BLE and other with RTC and BLE or AirLift and BLE. Interested in code/idea to share the current time to the lower capable device.
grizzled talon
@normal vale The code is available at the end of my original post. If you are planning on porting the code to other hardware, make sure to keep in mind you may need to adjust the "tick" variable. For the clue it's set to delay 465 milliseconds for a "half second". This is to counter-act the processing delays caused by the nature of the hardware. This is so it can try to keep time just a bit more accurate when it's off the bluetooth connection. Hope this helps!

The second one has the added advantage that you don't have to reflow your SMD components onto the board. Instead you have the option of just soldering an authentic Powerboost onto the board. Either way the board will then patch +5VDC, GND, and the LBO signal into the RPi header for you, plus give you a programmable tactile button and LED, and a SPST slider switch attached to the ENable signal.

vale wasp
Oh jeez, circuit python... If this were C I could give you constant optimization recommendations... Are the display and the MCP on the same bus @split moth?
split moth
Yep, both SPI
Haha sorry I forgot to mention the language
I could try using the itsybitsy analog ins instead of the mcp, just to see if it plays a role. Although I am getting much more stable values with the mcp
vale wasp
Are they on the same bus? And this setup is fine
Im confused why the values from the SAMD were not stable but the MCP works fine
split moth
They were fluctuating by about +-1% more than the mcp. And they are on the same bus yes.
Btw, the changes that are reducing the lag are those that make the display change less pixels / frame. For example if I scale the labels less, or make the progressbar thinner, I will get a boost.
vale wasp
So the MCP is actually really fast, it just needs two or three SPI clock cycles between each read, could you take some time measurements for me?
Instead of a delay, lets just use the display draw, but I also think you might want to split rendering and reading loops
split moth
At the moment unfortunately not because The whole project is at work and I am already home π

My project for the day was to use a QT Py to build a USB Adapter for an original NES Controller (written in C, using Keyboard library). Started with a Nano on my βMCU Labβ board ...
Might try it out in CircuitPython as a learning experience, havenβt written anything in CP yet.

The NES gun would require a different setup, this only works with the standard controller.
Old light guns used a trick with crtβs ... donβt believe thereβs any way to make them work with modern displays.

I created a project I call a βmicrocontroller trainerβ that carries an arduino nano, an esp32, an esp01, and a pi zero. https://wiki.bluesmokemonster.com/index.php?title=Microcontroller_Trainer_Rev_2
Would love feedback
covert silo
@latent terrace looks pretty good especially for a lab setting. Users would have so much options and flexibility in terms of prototyping IoT devices. They could do both, device and server on this board. I dont see any sensors though. I think a few on-board sensors would be a good addition like temp, hum, imu. And the rest can be added on the bread board. Maybe some battery option as well so that they can make it portable if need be to test the device. A newer Bluetooth module would be nice. (BLE 5) And some solid documentation with example projects is key to a product like this. Although you might not be looking to sell in which case makers can figure it out relatively easily themselves.

Iβm working on the next rev right now and it includes a lipo π
Iβve tested with the AT-09 BLE module and itβs pin compatible with the HC05, although I havenβt put it through itβs paces yet
Iβm also including an expansion socket to allow adding new microcontrollers (such as a feather) with ease, while not taking up breadboard space
Also some banana jacks and BNC connectors for test and measurement interfacing

Made a pair of Star Wars Rebels punk jackets with animated lighting effects. Mine runs on a Nano, hers on a Flora.
I overhauled the Fire2012 flame code to work with these, wrote additional code for my lightsaber and her (not shown) blaster, and added a "super bright" momentary button that ramps up brightness to max for 10 seconds after press.
Both are powered by pocket-sized USB power banks, and since they're at nominal-brightness most of the time, one small power bank will last many hours.

Nothing spectacular (yet) but its thanks to a lot of help from some people here so I thought I'd share, finally got a voltage divider working and my ESP32 is successfully sensing battery voltage, so now I can trust it to not overdischarge my batteries and now I can continue working the rest of the bot while on battery power (Couldn't do it on PSU because PSU is only 2A)

Couldn't help but take a little bit of avian inspiration from @fair vessel
subtle copper
HI! I'm building a CiruitPython IDE that's browser-based and designed especially for use on Chromebooks. Even though it's easy to write code in a text-editor and drop the file on the a plugged in-module, there are still steps in involved in that can be tricky to follow correctly and slow especially when you are iterating your code a lot. The IDE I made loads code temporarily right through the REPL, so as long as the device is "tethered", you can just keep loading/iterating. It also makes it really easy to load in any of Adafruit's example code.
I'd love some help beta testing it and seeing how people use it.
You can try it out at https://slappy.io/
sharp comet
@subtle copper Neat! I like the way that you can load examples inside of it. Would love an option for side-by-side instead of above-and-below.
subtle copper
okay, thanks for the feedback, I'll add it to the list
I also plan to add graphing as well as the console
bitter hazel
sharp comet
@subtle copper Trying this out on a few devices today I am not seeing my devices get listed in the list when I click the connect icon.
Mu and putty can both see devices connected to my PC (though they weren't open at the time I tried slappy.io) I've never messed with web usb serial before. Not sure if there is some other setup needed for using this with devices?
sharp comet
I like the way these "Elton John" star eyes turned out.
subtle copper
@sharp comet What device, computer, and browser? Do you get a box asking to connect but no devices show in the list, or does nothing show at all when you try to click connect?
sharp comet
I tried with PyPortal, and Monster M4sk. Win 7, Chrome browser. It opens a list but the circuit python device isn't in the list.
The only think listed is an unrelated Intel hardware built-in to my PC.
subtle copper
one thing to try, although I don't think this will fix it, is in chrome, type chrome://flags into the address bar and turn on experimental web features (it will require restarting chrome), and see if they connect after that. I'll do a bit of research and see if I can figure out why they aren't showing up and try to get back to you
@sharp comet I think I found out why - It appears that WebUSB is only supported in windows 8 or higher. Slappy.io uses WebSerial, which is built on the same foundation as WebUSB - I'm learning that if it doesn't work for WebUSB it probably won't work for WebSerial, either, but it's so new there isn't a lot of troubleshooting info out there. I'm so sorry π¦
sharp comet
@subtle copper No worries. Thanks for looking into it. This is definitely a reality I've grown used to for a Win7 user these days. Making the jump soon to Linux

@sharp comet When you make the jump to Linux, I'd love to know if it works for you there. Keep me posted!

I made a keyboard shortcut device for my niece for remote learning using the trinket m0. It's setup for google meet on a chromebook to mute video, mute audio, mute both and bring up the help menu. Total cost is $15ish.

Neat! I like the enclosure you used.
lucid bloom
I designed that with openscad
That flat rectangle slides in under membrane keys inside the middle part to give it a hard surface behind the keys.
lucid bloom
I designed it with an eye towards making more, only tool required is a soldering iron to put the pins on the m0. Assembly is easy, the case slides together. If I had all the parts I could make one in about 5 minutes. The case takes about 3 hours to print.
sharp comet
Nice, I am a fan of OpenScad as well. It's really nice to be able to put programming knowledge and experience to work on other things like CAD modeling. I like the way your enclosure is clean looking and sturdy but doesn't require any fasteners or other hardware to hold it together.

Looks good! The thought is to have it change behavior in some way depending on what the RFID reads?
gleaming sluice
Yup! Both my Jedi and Sith one will have that ability in the future (I hope). Disney has custom "Kyber crystals" (just resin based crystal with an RFID tag inside) that I would like my Holocron to be able to read and change color based on the crystal that is inserted into the device.
desert timber
Should be doable with a minimum of components. You are using a LiPo battery so it has no cord?
gleaming sluice
using this setup (picture from Adafruit's site). Plan to include a Micro USB (assuming I get the proper certifications to sell it). Either way it will be a nice personal project to complete, even if I never bring it to market.
desert timber
One suggestion - there are "protected" usb chargers out there (this is an example) https://www.addicore.com/TP4056-Charger-and-Protection-Module-p/ad310.htm
these have FETs to prevent battery damage in addition to the charger chip (TP4056)
gleaming sluice
Oh , fantastic, and they are reasonably priced as well. Thank you for the advice!
desert timber
they are all over, the two extra components near the output are the thing to look for
Good luck with it, my suggestion is to build one, or 10 for friends. If it looks like it might take off - then call the lawyer π
gleaming sluice
Thank you! The basic ones I have constructed seemed to be liked by those around me (just basic LEDs and a battery). Have constructed about 50 of them thus far. Glad I stumbled on the FCC guidelines when looking into RFID readers (as well as this discord)
desert timber
I can't disagree with the sound advice given earlier, but practically, until you are making them in vast quantities I doubt an RFID reader will cause trouble, especially if you find one you know is certified.
gleaming sluice
Agreed, I need to do more research as well as find an RFID reader that is certified.

Here I'm using the accelerometer on the CLUE instead for the cursor's X,Y, and moving display layers [opposite direction] based on their supposed depth. The display rate on the Feather M4 and the CLUE were similar until I scaled up the layers to accommodate the resolution difference. I culled out some of the sprites I had playing on my original test, and tried not to use scale on the display layers, but increase the resolution of the images instead. That seem to help some, but it is still a little slow. https://www.youtube.com/watch?v=u2Afm136B7A
Here's the original one from the Feather M4 https://www.youtube.com/watch?v=0K62C0gJl6U

@hard oriole are you manually controlling the refresh rate?
hard oriole
@lapis jasper no, nothing that sophisticated. By display rate I meant perceived ability to update to current state, without things such as [the cursor] jumping position, tearing, or disappearing. In the Feather demo I was using addition to make layers move in x,y +1 or +2, etc. pixels with button press depending on that layers depth. On this Clue version I'm using the same idea of the Spirit Level Demo, multiplying the x,y of the accelerometer by different values based on their supposed depth. I am jumping a greater number of pixels on the CLUE, which is probably causing some of the stuttering.
lapis jasper
@hard oriole if you are moving multiple elements, then it'll likely improve performance if you switch to manual refresh. that will ensure only one screen update per frame
hard oriole
@lapis jasper Oh, thX! I will give that a go.

No, literally just replaced the micro port with USB C port. Is that a problem though? Don't those chargers start at standard USB voltage and then ramp up to 20V after talking to the device? That's what I always assumed. Nonetheless i've never dared to plug in a potentially higher voltage charger to a lower voltage device.
candid crescent
Yes, USB-C starts at 5V and only ramps up if the device requests it via the PD protocol.
vale wasp
@torn elbow There is a product called the EZ-PD from cypress that is used to replace old barrel jack products into USB-C PD inputs. With resistors you can select you need 20V and at what amperage. Or you could start at 5V and tell it to change over i2c.
For me it just makes a really nice PD controller compared to other offerings

The first screw will go in straight but the second one will be at about a 30 degree angle until it is screwed all the way in. I used plyers to rotate the screws when it got tough by hand.

@lucid bloom If your sign is too bright (up close) I made a parametric light diffuser generator for HUB75 displays. You can print it in multiple parts that just slide right over the panel(s). It also works great if you use clear PETG with regular ol rectlinear infill (100% or just set loads of top/bottom layers). The faster you print clear PETG the more frosted/diffusion you'll get!
Here's what it looks like: Left half has the diffuser. Right half doesn't. I believe I used white PLA for this one because this particular panel is ridiculously bright (it's an outdoor model).
I recommend printing out little squares of different filaments and just hold them up in front of your panel to see how well they diffuse the light. You can test for thickness pretty quickly that way.
Check out these super cute 160x80mm HUB75 displays I got the other day! The plan is to turn them into a keyboard wrist rest but I also want to make them into dual touch pads (left controls text cursor, right controls mouse or vice versa for lefties like the now-ancient Fingerworks Touchstream LP). I have to figure out how to lay out a capacitive touch grid over the LEDs without messing with their light diffusion though. The ultimate plan is to cover the whole thing with thin veneer so it looks like normal wood π

I created a framework to automatically publish data from a Google Form to Adafruit IO. The specific use case was so students could send quotes to the Matrix Portal set up in our classroom, but I designed it in a way that it could easily be used as middleware for any project as a connection between a public form and a private feed. The Python script checks for updates to the form, validates any new data (in this case, ensures a valid color and profanity-free text), and publishes it to an Adafruit IO feed. Figured this could be useful to others, so I went ahead and posted it. Let me know what you think or if you have any feedback!

Here's an guitar audio project platform that's almost finished. The aluminium pick guard is so I can mount 15cm long perfboards easily via screws. The pickups currently don't connect to anything (it's hard-wired for just the bridge p'up) because I'd like to explore a bunch of switching options and maybe try to include a built-in boost/overdrive circuit. There is space for a 9V battery in a cavity that's behind the gap between the two pickups.
It looks quite a bit paler IRL. I painted it gold hoping that it'll look slightly different each time due to stage lighting.
One of the ideas I'm keen to try is to stick a joystick in there and use it to actuate a "digital" whammy bar.

@remote sigil : I would have done it another way. when you change status to "counter", I would have called time.monotonic() and stored it in a var, and call it again, substracted from the variable, when you want ( when updating the display and when switching status to "finished"). This is more accurate, imho.

Not much but I'm making a minimal library for the HM-18 BLE devices (AT-based) that does nothing but:
- initialise (on tx/rx or desired pins)
- set BLE device name
- allow command/handler assignments via a 'dict'
- listens for said incoming commands (pairs of N command chars + N value chars, eg with
length=4arg: AB12 would be - command: AB, value: 12, so 50/50 split and can be customised. short strings to keep data requirements low but still allow lots of variation) - calls appropriate handler for commands that exist, else if it's a matching length but does not exist, notifies user - otherwise fails/ignores completely.

I recently bought a game art pack and while exploring the assets ran across these grey-scale pattern tiles and envisioned a random "patchwork" generator running on the MagTag. Been sitting here mesmerized resetting it for several minutes.

Very cool looking stuff @sharp comet! I find it so interesting that the pattern effect "feels" different from the small preview photo form than full-size. And I can barely tell you're trying to hypnotize us! π

@brisk geyser Hey! Nice project! If it's using CircuitPython (or Python in general), consider submitting it to the Python for Microcontrollers newsletter. You can post to Twitter and tag (at)anne_engineer or email anneb (at) adafruit.com with a link, images or video clip, and she'll get it sorted. This week's newsletter is already finalised, but it would be an excellent addition to next week's!

I had a terrible security camera with a big battery, so I replaced its insides with a pi zero and installed motioneyeos on it. The camera has infared lights and I used the NOIR cam so I can get glow in the dark.
The battery is able to support the camera's big control board for a month, so I'm sure it won't have trouble with the pi zero
Usually, motioneyeos does all the processing onboard, but because I wanted to save on power, it only streams video to another motioneyeos on my server pi in my house, which processes the motion detection

@polar eagle Nearly all the prototyping has been done over the past six months or so trying out different switch designs. For the actual keyboard case... This is only the second prototype. First one was fine, really. I just made some minor improvements
@spring elm Yeah it's all FDM. I've had a friend print the switches on his resin printer though and that works fine too
Honestly though FDM is better for this sort of thing. Resin gets brittle over time and is likely to break off inside your expensive keycap getting stuck there forever π€·ββοΈ . With PETG that isn't likely to happen (it bends before it breaks)
PLA+ or PLA Pro works fine though. I tried that out. Once lubed it's about the same as PETG on PETG

My Logic Gate Demonstration kit - born of my math circle were I was explaining to the kids how one constructs flip-flop from NAND gates. Now I can show it to them in hardware, not just simulation:

Here is the flip-flop on my fridge door:

I take it they're electromagnets, and when the gate's output is low, they fall off?
marble mantle
That would be interesting. Especially when setting/resetting flip-flop π
But alas, reality is more boring - the magnets are usual ceramic ones.
civic vale
@marble mantle Looks pretty cool. One suggestion (partly extrapolation from a friend who has a similar group) you have a number of participants who'll just "wow" and go on, but a hardcore group will want more. The later group stays on longer and you teach the advanced skill of actually assembling circuits by having them build additional circuits (you need to have the parts ready to go when they hit this) and they get to keep 1/2 of what they make and in exchange for the parts in those, they donate the other half to next years students. In this way you eventually build a larger supply so you can build more things.
And one thing I noticed you don't have is "fan out". This could be a really simple (i.e. almost no circuit, maybe just the LED indicators) board, or just a spliced wire. But more than the simplest circuits will need this, so you might want to mention it.
marble mantle
@civic vale thanks! Just waiting until coronavirus vaccine makes it all possible.
As for fanouts, there is in fact a fanout in each board - each board provides two connected outputs, which should suffice for most purposes

@dapper yacht and @indigo charm if you have Chrome browser you can use this web serial ESPTool. You do have to enable a setting inside chrome.
