How could I make my own games for it?

[spiral mist]

check any of the games in source\cglpfruitjam\src\games how they do it. Create a new c game there (can start from source\not_included_games\game_Template.c) then in source\cglpfruitjam\src\lib\menuGameList.c add your game's init function, you may have to increase MAX_GAMES_COUNT here if you reach the limit

Am I allowed to share vibecoded projects that I got working here?

[lapis jasper]

I made a Distributed Display Protocol receiver library for CircuitPython! Distributed Display Protocol is a way to control LED strips over the network. Right now one ESP32-C3 runs WLED, and the second ESP32-C6, which can't run WLED but can run CircuitPython, receives messages from the first. It behaves as if the end of the LED strip that is soldered to the sending device continues on the receiver.

Just wanted to share a progress snapshot of my build of the Ruiz Bros' + Liz Clark 2 axis camera slider project. The physical build has been nice and simple so far. I modified the limit switch plates for switches from my own stash, and I just 3D printed the axial stepper gear rather than buy one. Now I'm working on the electronics and I am deviating quite a bit from the BOM build since I already have a bunch of stepper drivers, a screen, and am using a Pi Pico since I'm not willing to sacrifice my pink KB2040s 😂 . Ultimately if/once the electronics work, my plan is to solder my own perfboard to slap on a custom PCB tray and power the whole thing with a USB-PD battery pack. Considering the complexity of the circuitry I may or may be in over my head. We'll see, I might have to go back to the BOM build if things start going wrong.

MicroPython running on Baochip Dabao Bao1x eval board. This is using a board support sdk that I wrote in Rust, but it builds to a C FFI library that MicroPython's makefile can link to.

At this point, none of the hardware support is implemented in MicroPython except for the UART driver. But, one thing at a time.

[clever stone]

I have not heard them called "CYD" 😜 ... they're not cheap and they're not yellow. 🤓

The original post is a SHARP Memory Display. They are an interesting bit of technology.

Was just keeping the thread going. Your display doesn't have to be a CYD

[sly rampart]

CYD is a very specific combination of an ESP32 and a specific resolution display driver, it's not a general "every microcontroller project running some sub-laptop screen" term.

And you're the one that started implying it was a CYD out of the blue so folks were confused by your statement. 🙂

Oooh, that is cool. I have tossed around ideas similar to that in my head a few times but never built anything. Super cool to see it come to into reality.

[lucid bloom]

I got my Mentra Live smart glasses today and deployed my first app.

HindSight listens to conversations through your Mentra Live glasses in real time. Every time someone finishes a sentence, it silently sends that utterance to Claude in the background. If Claude detects a logical fallacy — like an ad hominem attack, a false dichotomy, or a slippery slope argument — the glasses speaker whispers just the fallacy name in your ear, so you know what's happening without interrupting the conversation. Everything gets logged: the full transcript plus Claude's reasoning for each flagged fallacy, saved to a file you can review later. Short press the button to hear a spoken count of how many fallacies have been caught so far; long press to save the transcript to disk.

Unboxing to app deployment was under 2 hours because it is very easy to work with. I plan on making a bunch of apps

[clever stone]

Good to know. I'll be paying closer attention to wearers of what appear to be smart glasses.

[lucid bloom]

Yea these are open source ones so they won't be scanning your face like meta wants to do.

[clever stone]

Recording my voice without prior consent is equally concerning.

[lucid bloom]

It's not recording it's transcription there is no audio saved

[clever stone]

The audio goes to Claude and unless it's all local, it's out there.

[lucid bloom]

No, the text goes to Claude. Why assume things you don't understand

[clever stone]

Perhaps I misread the post. It said "sends that utterance to Claude".

[lucid bloom]

I am not recording audio

I am going to share the code soon, it's pretty basic and that's why it's so great because it's a truly open source platform that took me no time at all to be able to create things with. I could make it do things people would have problems with but that is not my goal
https://mentraglass.com/

[clever stone]

Thanks for the link. It clarifies that Mentra Transcription Manager is a Cloud service.

[lucid bloom]

It's not like I cant self host or process on my phone

[clever stone]

And it's not like I want my voice sent out into the cloud without my consent.

2-party consent states include: California, Delaware, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, New Hampshire, Pennsylvania, and Washington

[lucid bloom]

It is generally legal to record or film a face-to-face interview when your recording device or camera is in plain view, or to record any type of conversation when the parties are warned of the recording and continue with the conversation.

[clever stone]

"when the parties are warned" is exactly what I would expect. So long as you announce your intention prior to conversation, you are being proactive an respectful of the other person.

[lucid bloom]

There is an or there I could be listening to something or not have any apps active. How would you know?

[clever stone]

Precisely my point.

[lucid bloom]

The whole meta thing seems far worse where they would just constantly scan and log faces

[clever stone]

Neither seems to put personal privacy first.

[lucid bloom]

Welp having a smartphone is far worse for privacy, same with going online. Unless you are specifically trying to maintain privacy, you have none.

[clever stone]

A person's use of a smartphone is their choice. The smart glasses put the control in someone else's hands. I don't consider these the same.

[lucid bloom]

So what do I have to control to do with these glasses? What bothers you most?

[clever stone]

As long as the other party is informed prior to engaging in the conversation, then they have the choice to participate or not.

[lucid bloom]

So only if I'm actively running an app that uses the mic? Make sure to tell them, point out the glasses and then keep talking? I could be live streaming video without audio and that's legal.

[clever stone]

See my comment regarding 2-party consent. Smart glasses may not be an obvious recording device.

[lucid bloom]

Mine are they are transparent but not all of them are

[lucid bloom]

https://github.com/matt-desmarais/HindSight/blob/main/index.ts

its pretty basic, I could easily turn it into a fact checker by changing the prompt

[sly rampart]

Legally the instant you digitize from the microphone? You're recording.

Even if you delete it after processing it or convert it to text, you recorded.

Many states in the US and countries elsewhere are two-party-consent states for audio even if visual/video is allowed in public. Audio recordings especially of peoples speech are often held to a higher standard.

[lucid bloom]

I guess I will try and do something 100% legal everywhere that makes people uncomfortable like "NameTag" that whispers your name in my ear. I'll make sure to mention metas plans when they try to take issue with my silly little app. There are millions of metas Ray-Bans, there are only 1000 Mentra Live glasses out in the world currently. I'll probably have it done and tested before end of business day, API will cost thirty cents per face.

[lucid bloom]

It works, I identified myself in under 10 seconds. It's very obvious it says "Capturing" then camera sound and led flash, it is not stealthy. I'm gonna make sure to get permission before I launch any of my apps with other people around.

[untold sable]

So basically glasses to make you a professional live troll in person?

[lucid bloom]

Personally I designed them for listening to politicians

[untold sable]

Why do you need glasses for that? Just assume they are lying and save yourself the money and effort.😆

[lucid bloom]

Lol I could but where would the fun in that be

Hmm... Maybe I could do something more useful. I'll have to think of another app. So far they each take about 2 hours

Basically I'm showing what happens when you add apis and ai to a pair of glasses on your head. I will attempt every bad idea I get just to see if they work.

anti-aliased font examples with displayio & lvfont files.

[clever stone]

The incremental results are very helpful. Thanks.

• What hardware did you use for your test?
• Did you happen to get any measurements on how much memory or time it takes to perform the anti-aliasing?
  (I'm not sure how easy either measurement would be.)

[sharp comet]

That screenshot came from a Fruit Jam with output captured by HDMI capture device. I didn't measure time or memory. Here are the sizes of the font files from the screenshot. I would assume they correlate to memory usage. This font was ASCII range only though.

I'm not positive but I suspect the only additional time is during the font loading. After it's loaded I think the rendering in a BitmapLabel will be the same speed because internally it's just bliting from the glyph to the Label's Bitmap and I don't think the blit action of the same size takes longer even when more colors in play.

[clever stone]

Thanks!

[sharp comet]

The example code and fonts are here if you or anyone else is interested in trying it out. https://github.com/adafruit/Adafruit_CircuitPython_Display_Text/pull/237

[untold sable]

For those of us not as, ahem, aheam, wicked sm'aht as some others, can you explain exactly what this is? Poking around I assume you give it any font and when it displays your text it is antialiased to smooth it out in before showing?

[sharp comet]

This page: https://lvgl.io/tools/fontconverter can convert .ttf or .otf font files into an lvgl font binary format. If you select a bpp value >1 it will buildin antialiasing to the converted font using the number of colors allowed by bpp. Once converted the font can now be loaded with adafruit_bitmap_font and shown on a BitmapLabel from adafruit_display_text with an appropriate custom palette sized for the bitdepth of that font.

And yep it allows some shapes especially diagonals and curves to be drawn in a way that typically appears smoother to the human eye.

[untold sable]

Thanks. I am definitely going to try it out. Playing around with ePapers and small TFTs a lot of fonts that look great on a 5k monitor from Google Fonts or whatever you get them from, that you hope will look great on smaller screen, not so much sometimes on tiny 0.0022k displays.

[clever stone]

We have done a few projects with the small 1.54" square ePaper displays. The 200*200 have good resolution but are 1-bit so anti-aliasing is not an option.

[sly rampart]

To be fair at 180dpi anti-aliasing is less of a concern.

Hi everyone, tscircuit is my open-source framework for making circuits with React. I know Adafruit is doing a bunch of stuff with AI and electronics generation, we are also trying really hard to make it work!!! Our biggest issue right now is placement

[bitter topaz]

Hey folks! 👋

I've been really wanting to build ultra-low-power BLE projects with the new Nordic nRF54 chips, but the official SDK has no gentle on-ramp — it's built for enterprise engineers.

So I spent the last two years building IOcomposer to fix that. It's a free IDE and C++ library designed to make nRF54 development as frictionless as possible.

To help skip the datasheet reading, I integrated an AI that's indexed directly on the hardware framework — because it actually knows the SDK, it doesn't hallucinate generic C++.

In the video: the AI takes a single prompt, generates a compiling nRF54 BLE project, maps the pins, builds it, and launches a real hardware JTAG debugger in under 3 minutes.

Still in early beta and definitely has some rough edges! But if anyone here likes messing with Nordic chips and wants to try breaking my AI or roasting my UI, grab the free download here: 👉 https://iocomposer.io

Would love to hear what you all think!

[hallow wedge]

Hello everyone my name is Mason! We engineered a wearable BCI using a Raspberry Pi 5 and PiEEG-16 to capture 16-channel brainwave data in real-time. During a live jazz performance, the Pi 5 buffered and sent neural data via TCP to a Raspberry Pi 4B, which mapped the signal amplitudes to the brightness of Adafruit NeoPixel strips integrated into the singer's dress. This dual-Pi setup ensured the performer remained electrically isolated and safe while turning brainwaves into a live light show. Our organzation is called Decoded Brain.

[raven shale]

It's been basically a month since this update, but it took some weekends to adapt the code to my hardware, then get it working on a breadboard, then to get it on a perma-board. I am somewhat surprised it worked, and the code changes were somewhat straightforward actually. I will say that if you're thinking of doing this project, don't already have parts on hand, and are able to (since certain components are pricey and others are perpetually out of stock), getting the parts from the Adafruit website and ordering custom PCBs will save you a ton of time and effort if you just wanted something up and running right away (This project is making a case for me to learn how to design or at least modify PCBs for my parts). Final step is to do some CAD work for a PCB mount/cover and cable management.

I've been using it for a number of years, I finally wrote an article on making an infrared remote for my Sony NEX camera using the Circuit Playground Express board: https://www.instructables.com/Sony-IR-Remote-Control-Shutter-Adafruit-CPX/

[clever stone]

Do you use encoders for the slide positions or use limit switches and always travel the entire distance?

I'm curious because I do a 3-axis camera slider and had to do something similar to 3D printers where I "home" all the axis and then have to use motor controls to position. Your method of just pushing the slider is much easier.

[raven shale]

This is actually Adafruit's project found here: https://learn.adafruit.com/motorized-camera-slider-2-axis/overview The code basically just counts steps based on the stepper settings (microsteps and rail length). There is a limit switch at the front for initial homing and then a limit switch at the end that acts as an emergency stop. This setup is meant to pan from end to end. The one issue I'm having right now that I'm trying to fix in #help-with-projects is that while this setup works, the steppers are extremely weak despite me adjusting things like run_current and microsteps. So have to figure that out.

[clever stone]

Thanks. I wend down a ver different path so the code bases are not at all alike.
As for "weak steppers", what voltage are you using for the motors? I settled on 12V.

[raven shale]

12V. I have conversations ongoing in that channel so I'll continue working on the problem there.

[real bobcat]

My current project is a wrist watch that has a metronome. Hardware used is a QTpyRP2040, IoT button BFF, EYESPI BFF and the 1.28" tft display. Using Circuitpython 10 libraries. This is a demo of the prototype showing some functionality. The button BFF and the boot button on the QTpy are the controls at the moment.

The start is showing setting the clock functionality. Then moves onto switching to the metronome. Cycling through through BPMs. Then back to the clock.

I have additional features planned but I might need custom board to connect it all. The current board that comes with the display seems build for other uses. I put in a request with Adafruit to see if they can release an alternate build of the current product.

You can clock it externally or internally and the joystick makes it fun to use. If you hold down button B it goes into emergent paint mode and you can paint different lfo values onto the squares. https://youtu.be/NJfJKkbMPoc?si=hbBZNpBBUI6_1vp_ and the repo is here https://github.com/machinehistories/hidi_lfo

This is my diy UnioNet LoRa Mesh node. The hardware is an esp32 wired to the Adafruit m0 RFM9x LoRa radio module via UART. The esp32 serves as the UART bridge and is connected to this old phone via OTG cable. Im running a serial app and can control the Feather with my phone via the bridge. This does not use MESHTASTIC or MESHCORE firmware. It uses UnioNet LoRa Mesh built on the Radiohead library.

Looks great! Have you measured the jitter or accuracy of the result?
I wonder if they could output millisecond-aligned pulses at 500Hz?

[signal kraken]

That is not the design intent. It aims at 100mS accuracy.

I kind of want to do something like that with an analog clock. Much more dificult, though. Would require sensing the current positions of the hands, then adjusting them to match the current time.

[inner socket]

Curiously that's how a lot of clocks where set, they'd have sensors at noon position for both hands then be forced to pulse fast until the hands hit the target

My PortaProgXL is based on the TesterBrains created by LadyAda for the manufacturing floor at Adafruit. I would not have been able to create my PortaProgXL without their open source content.

[river isle]

Hello!
I finished this project recently and wanted to thank you guys here at the Adafruit Discord. It's a project I spent about a year on and got a lot of help in the beginning from all you fine folks here! This is model rocket flight computer using a Feather RP2040, Qt-Py RP2040, Adafruit GPS, and many other Adafruit products. Here's some pics and a YouTube video I made talking about it.

This represent what I often tell younger engineers. You don't learn much when your design works. You learn almost EVERYTHING with your failures and usually don't forget what you learned. Embrace the failures!

Yes! Exactly. It always hurts, but you have to just take the lesson when it doesn't work out. Then, when it does - it is so much more sweet!

[umbral plinth]

Hey everyone! 👋 I wanted to share a project we’ve been working on called bUniProbe!

It's an open-source wireless hardware debugging tool that is now in pre-launch on Crowd Supply. If you've ever struggled to test a new I²C sensor or debug a SPI display, we built this to make it easier. Instead of juggling USB adapters and wires on your desk, it packs SPI, I²C, UART, CAN, GPIO, ADC, and **DAC **into a single Wi-Fi connected platform.

A few features I think the maker community here will appreciate:
- Browser-Based (No Drivers): It hosts its own Web UI. You can read/write to sensors or toggle GPIOs directly from your phone or laptop browser without installing any software.
- Built-in Level Shifting: You can dynamically switch between 3.3V and 5V logic right from the UI (no external level shifters needed!).
**- Waveform Viewer: **Monitor analog/digital signals on the fly to see what your hardware is actually doing.
**- REST API: **Control and monitor interfaces programmatically (perfect for scripting with Python!).

It's going to be fully open-source hardware and firmware. We'd love for you to check it out!

👉 Check out the specs here: https://www.crowdsupply.com/bitmerse/buniprobe

I've added an APX803S to the reset circuit so I don't have to use a precious IO line from that QTPy. With /CS tied low (only 1 SPI device), I2C is available again, yeah! This video (https://www.youtube.com/watch?v=LgYVcFWEDaU) was very helpful even though these Jelly Beans are readily available again.

[glad roost]

Thanks!

[sand grotto]

Looks great and works really well! Just curious if you know what triggered the reset / code reload between #3 and #4?

[clever stone]

As a matter of fact I do 😜
The "probe wand" slipped and shorted a pin to GND so the PortaProgXL simply restarted … but it is so quick 🤩

If the pads where thru-hole and/or 2.54mm then the probability of this occurring would be very low but these PCBs don't have the space so the pads are SMT and the pitch is only 1.27mm.

[sand grotto]

Ah, i wondered if it was a slip of the wand🪄 the danger of being a live circuit wizard I suppose 😁

Especially edge cases. I once made a PH adjuster for my pond because the makeup water was PH 9.5 and nothing wanted to live much above PH 8. ESP-32 and some pumps and tanks and acid allowed me to fix that. But a weird sequence of events caused the acid pump to discharge all of the acid into the pond, killing everything. The fish jumped out trying to survive. The plants failed. I felt horrible for weeks. Still do, actually, but one must continue.

Moral of this story? You can’t always check the edge cases because you don’t know where they appear, so design conservatively. For me personally, don’t do anything life-safety related.

It's a tool to help people make touch-based projects super simple and as both an introduction to electronics but also powerful enough to run fully fledged installations.

UXB-300 Codeless GUI w/ KB2040-based I2C Bridge

Hi everyone!

I wanted to share a tool I've been working with called the UXB-300 by Labs16. It’s a browser-based GUI builder that lets you wire up register-level control of a target IC without writing any code.

Instead of writing a custom script just to read a register or MCU parameter, I used the UXB-300 to build a graphical interface in just a few minutes. While off-the-shelf dongles like i2cDriver and MCP2221A are supported, almost any MCU can be configured to work with the tool.

I created a Note in the Playground where I used an Adafruit KB2040 to act as the USB-to-I2C bridge, and then used the UXB-300 to control the LPS22HB sensor. I’ve documented the full setup, including the RP2040 code and the GUI logic, over on the Adafruit Playground:

👉 KB2040 as I2C Bridge with GUI Control

Highlights:

• Uses common, off-the-shelf Adafruit products
• Uses the on-board STEMMA QT connector for plug-and-play I2C.
• Provides a simple browser interface to send/receive data.
• Great for rapid prototyping before committing logic to a standalone project.

Happy to answer questions, and curious what other examples folks would find useful.

First level of conduit is laid and buried! I decided to run a second shallower conduit for Ethernet to keep data and AC apart.

[lofty latch]

If your conduit is not iron, I would suggest keeping them at least 1 foot apart to eliminate EMI between them.

This is especially true if you are going to be pulling the amount of amperage that you mentioned on show and tell.

[plucky otter]

That's the plan. I am at 20 inches for the ac, so I am going to place the Ethernet at 8. When I get to the wall, keeping clearance will be a bit harder, but I think I can manage 8-10 inches, and that is just as the ac comes out of the ground, I won't be doing a parallel run an a distance of less than 12 inches.

I designed a similar project to the map one for someone and they asked could the "leds sparkle" and I was like.....

When using the network part of the esp8266 you need to be conscious about your animations

[marble tapir]

But seriously, overview, I have a palette, 0-255 are all assigned to a color. Then, for each pixel I pick a number between 0-255 given its position and the current time.

"Dual coring " a project

[marble tapir]

I always joke about doing that, but it would make for a simple solution

Oof, trinket 5v (non-pro) only has 512 bytes of RAM

For my project it could buffer the neopixels writes and not much else

[solar yew]

I think if you map parameters to rotary encoder(s) you can make up the artistic part as you go along, much as you would setup a voice patch for an old school, monotonic music synthesizer.

Then just hard-code the coefficients when you know what values to plug in, from live experimentation.

https://forums.adafruit.com/viewtopic.php?f=60&t=114694&start=15#p599656

I have four parameters in the function that does most of the interesting work in that program (see link). If they were mapped to rotary encoders, that'd be a lot of fun to play with in realtime.

48:  # ------------------- pseudo-ADSR -------------------
56:  def pulse(t, decay, sustain, fade, halla):

I called it pseudo-ADSR because it reminds me of an analog synth's ADSR envelope-generator (attack, decay, sustain, release) which is used to shape individual notes played on (for example) a piano keyboard. Usually it shapes the volume (sound loudness) profile.

So I think the real creative LED-art is coming from a composition tool (a project in itself) - probably with knobs and sliders and such, very much like an analog synth.

[solar yew]

@mystic ruin There's a ham radio gadget (MFJ 890 = Atomic DX Beacon Monitor) that works something like what I saw in the still photo of your project. I think it has LEDs embedded on a world map; the LEDs light up when band propagation conditions /from/ that location (to your own) are favorable.

[marble tapir]

@mystic ruin Congrats!

@solar yew ADSR is a great idea for making good looking light patterns. At one point in this project I was trying to implement it, however I wasn't happy with the performance I was getting out of my version.

[solar yew]

@marble tapir I'm calling what I did pseudo-ADSR as it's basically a sine wave function with .. um ..stretches.

Sustain is when the keyboard player holds the key down for a duration (and is generally arbitrary in length). Attack, Decay and Release are what shapes the note (presumably a fancy keyboard can sense a fast attack and present that signal electronically).

timbre is primarily an admixture of harmonics.

The difference between a reed and a flute and a plucked string and a horn all at the same pitch is timbre.

Square wave has an exact mathematical relation to a sine wave at the same fundamental frequency.

Probably defined as specific harmonics present along with the fundamental.

Triangle and sawtooth waveforms, same idea.

[marble tapir]

Yep, I love that kind of stuff. I'm actually a music major (hence the reason my project is music based).

[marble tapir]

Haha, that the stuff she normally plays, but she breaks out the classic rock tunes to show off

[solar yew]

@plucky otter extension cords have a finite resistance (in Ohms) per foot. A longish cord (100') can seriously damage modern motors, due to undervoltage.

Old motors have enough thermal mass to tolerate the higher current draw:

Current = Voltage / Resistance    I = E / R

Power =   Voltage * Current       P = E * I

Since the motor has to do the same work, no matter what the voltage, it draws more current to make up for the undervoltage -- and that heats the motor (more).

[plucky otter]

@@solar yew Yeah, this is why I just spent more than i paid for the microscope on getting 80 amps of power to my shop. I will have plenty of power once I get everything tied into main panel.

how was the neopixel messing the ir reciever? @tame fog

I think it's using the interrupts that the ir is using so it won't receive codes from the remote.

The Feather M0 Express (bottom centre) is unusual in that there's a physical means to operate the RESET switch without opening the small plastic enclosure housing the target board. I utilized the (considerable) travel the transparent lid makes, to seal the super-thick, pliant rubber gasket -- there's a boatload of travel, so that travel is leveraged as my (gasket-rubbber-powered) spring-return, for a column of 2.5mm nylon standoffs passing through a hole in the lid of the enclosure, directly over the reset button of the target board, acting as a button actuator.

I adjust the tension on the cover screws for the correct 'feel' to the reset switch. Instead of drilling the lids for all these enclosures, for the various reset switch positions in their respective cases, I plan to remove the hardware of the one I have now, and re-drill for all other needed locations -- and swap lids depending on which box I'm working with that day. So that any of them can be reset with the lid closed.

Parallax worked remarkably well, for centring the reset switch actuator hole in the lid of its enclosure. The reflection of my eyeball in the lid was my alignment point for the drill bit tip.

[robust fiber]

Oh my. The cases alone look really good. There is this steampunk vibe going on that I really like. Good job @solar yew

[solar yew]

This got released today:
https://github.com/wa1tnr/ainsuForth-Gemma_M0It's a working Forth (an interpreter, connect via USB 19200 bps) for the SAMD21E18A (Gemma M0).

[marble tapir]

@solar yew That's pretty cool looking!

[vernal ferry]

hey @mystic ruin https://blog.adafruit.com/2017/07/31/arduino-neopixel-traffic-map/ ;D

[mystic ruin]

Oh awesome! What a nice start to a Monday morning 😀

Thanks @vernal ferry for the heads up

[bitter valley]

How do I get on the show?

[mystic ruin]

You need to follow adafruit on Google plus

https://learn.adafruit.com/how-to-get-added-to-the-adafruit-google-plus-show-and-tell-circle/about-show-and-tell

The post for it normally goes up later

And then much later the hangouts link is added to the post

I do recommend jumping into a hangout by yourself to test your webcam and mic too, just to make sure everything is working OK

I might see if I can finish the soldering on my led matrix and jump on this evening

[bitter valley]

I will be at work until about 5:30/6:00, then going to the makerspace afterward and probably be streaming from there. Tonight is open hack night (even though I have a membership and can go in at any time).

[plain stream]

I was hoping to get on tonight but I'm leaving for camping tomorrow and haven't even finished my project, so it'll have to wait

[mystic ruin]

should be good to go for show and tell if I make it in

[bitter valley]

Am I in the show & tell circle?

[mystic ruin]

https://plus.google.com/events/cebgh62isd25jjgsmal523stavk

post here and ask to be added

just incase

I cant fully remeber how it works

I just remeber being added really close to the time!

[bitter valley]

Posted.

[lapis jasper]

I try to post the hangouts link here too

[marble tapir]

We'll be showing off Uke progress. 😄

[mystic ruin]

Taking requests @marble tapir ? 😄

looks like its going to be a full house

[bitter valley]

Link?

[mystic ruin]

Hasnt been posted yet

[marble tapir]

Hrmm, there's two posts

Which were we supposed to comment on?

[mystic ruin]

I think you should be fine as you are already added to the circles once you click the link

I never know either

One is to the Adafruit company page and the other is to the Adafruit Group or something

[marble tapir]

Yeah

Lots of folks want to join today for sure

[lapis jasper]

@bitter valley @mystic ruin @marble tapir https://hangouts.google.com/hangouts/_/xthcuhyvnzfnzlyt37zt3upoj4e

and you don't actually need to be in the circle, just click the link

if it fills up I'll drop out after I talk too

[mystic ruin]

nice colour shirt @lapis jasper 😛

@bitter valley is on now!

[clever pebble]

did you show something? @lapis jasper

[lapis jasper]

yup, the guides and docs I've been doing

[clever pebble]

i missed the start

[lapis jasper]

I was first 😃

[lapis jasper]

looks kinda like a segway @regal dagger

[mystic ruin]

Just watching the show and tell back, my upload is awful 😐

It settles down after the first few seconds thankfully

[regal dagger]

@lapis jasper i would think it basically is with the accelometer (sp?), right? except it has a third (rolling ball or freewheel type) balancing wheel on the back so maybe not. the balancing would be in the coding if it was like a segway, right?

[lapis jasper]

yup yup, still looks like it could be though

[regal dagger]

it does look like it indeed

if i had time i'd make it look and act more like a segway, dress gregor appropriately and take him out to burning man. haha that would be so funny.

[lapis jasper]

😃

[lean arch]

i had a strange idea for tackling a difficult concept

you guys remember google's project ara

modular phones

[modern cypress]

lets set up some modular i2c stuff? 😛

[bitter valley]

Hey guys, so I'm not planning on sharing any updates to my helmet and costume project today on the show since I need to actually work on it to have it done in time for the convention this weekend, but I could definitely do a quick summary of the past week of chaos here if anyone is interested (and if it's alright with the mods).

[lapis jasper]

go for it @bitter valley

[bitter valley]

Sweet! So after I made the helmet that I showed last time, I made a second one of the same design, only cleaner. Then I decided against that design entirely because the faceplate that I wanted to do would have looked very ugly, and it would have been stifling and suffocating.

So then I decided to redesign and came up with this second version of the helmet. This redesign was cleaner and allowed the full face covering, however if I were to use plexiglass as a visor, it would have fogged like nobody's business.

Then I decided to bite the bullet and buy a pattern off of Evil Ted's website that I had my eye on, and I think this one is a winner. It's a face mask as opposed to a full helmet, but the nice thing about this one is that I get the "anonymizing" aspect I was looking for, and if I were to cut eye holes instead of leaving it the eye area open, I could install some screen door material and that would be enough for visibility. I would need to make a strap that would hold the mask in place, but that could be easily done and the foam pad I plan on making could serve as a space for a gemma or a trinket. Tonight I have a lot of work to do to get it ready for the convention this weekend.

Oh, and the metal encasing is out of the question. Too cumbersome, and my metalworking skills are not up to snuff yet.

[lunar trout]

Haven't seen the link...

[plain stream]

That looks awesome @bitter valley !

[quiet quartz]

So i've finished my first year of GCSE and soon to start my second year. And for GCSE DT, I'm designing a wireless rechargeable lamp! It has four LEDs, a powerboost 1000c board and a 5v inductive charging set. I 3D printed the front and back plate on an Ultimaker 2.

This is the front of the lamp at a really bad angle 😆 my appologies

[misty heron]

These are of one of my RetroPie projects, built into an old Mega Drive/Genesis game cartridge.

[umbral fog]

@misty heron is the usb port just a breakout? or is there something else on that board?

[misty heron]

@terse totem There you go. ^_^

@umbral fog Just a breakout yeah, power in.

[umbral fog]

K

that's actually really effin cool

[misty heron]

Oh thanks 😄

Was pretty stoked to have found that USB hub in exactly the right size, three ports facing outward, one on the side, so I put a BT dongle in the side one so it's hidden inside. (This was like a month before the Zero W came out, damn it.)

[umbral fog]

@misty heron oh I know that "DANGIT whydidn't I wait" feel

[bitter valley]

Roast me. Everyone, please roast me. I need to get all the negativity out because I feel like it looks like garbage.

But it's what I've got.

[vernal ferry]

Kinda looks like REAPER

the shape anyway: http://overwatch.guide/wp-content/uploads/2016/05/reaper.png

[lapis jasper]

@bitter valley I think it looks awesome! I can't wait to see it lit up

[bitter valley]

Ok, plans for the next version... I'm not doing the whole damn face again. Just the mouth.

[terse totem]

That cart looks great, @misty heron

[bitter valley]

@lapis jasper Everyone keeps saying it looks awesome, but for some reason, I hate it.

I don't know why though!!!

I could possibly be exhausted. I don't know.

[robust fiber]

@bitter valley Has a very iron-man vibe to it.

[rare frigate]

@bitter valley nice kylo ren mask 😬

[plain stream]

you're always your toughest critic

is it supposed to "be" something specific, or just a cool mask? either way I like it... and like tannewt said, it doesn't even light up yet!

[clever pebble]

@Stuff With Kirby#8486 more like reaper from overwatch

[bitter valley]

@plain stream That's the thing. I have a vague idea of the aesthetic I am trying to go for, but I don't really have the skills or material to pull it off so I'm trying to make do with what I can use, floor mat foam and Plastidip.

[warm sage]

@bitter valley have you sketched the shape you've envisioned? The heart of engineering is truly making what you need with what you have, but having a really clear target makes the most difference early on

or is it more the texture than it is the shape that you're working on?

[bitter valley]

@warm sage If I had any semblance of art skills, I'd be sketching the hell out of concepts.

[warm sage]

@bitter valley they can't be as bad as mine, I struggle drawing stick figures

I wonder if maybe using 3D drawing tools would help you capture what you are seeing

[plain stream]

also, iteration is fine. so you do this, and say "actually this would be better if it had/didn't have X", and then do it again (within reason, of course). it seems like you already have. since you talk about facemasks fogging up and so on

[warm sage]

Agreed with @plain stream , conquer by successive approximation

[plain stream]

for me it's also more "oh I didn't know X when I started, and now that I do I can do it better"

[warm sage]

the process of refinement can be very satisfying, sometimes frustrating

[eternal maple]

Sometimes conceptual drawing is just practice, practice, practice laced with lots of do-overs. It certainly was for me, but now it's one of my primary skills.

[lapis jasper]

Yeah, just keep refining it @bitter valley . Making wouldn't be any fun if things were just immediately done

[bitter valley]

Well, I now get the feeling that a full head covering helmet may not be the best design for the character, however something like Soldier 76's Tactical Visor might be pretty cool if I were to somehow make it more original.

[clever pebble]

have you get those visors get show stuff?

[bitter valley]

Not anywhere close to doing that yet. I can't even settle on a design for the visor. I'm thinking that for Mk. IV, I'm just going to cover the mouth and eyes, basically creating a mask that covers the negative space of the helmet I showed last week and then somehow figuring out how to mount neopixels onto it.

[clever pebble]

you could think small projector to project data to visor

[bitter valley]

On the inside of a mask? I don't think they make projectors that small.

[plain stream]

eventually you could do something like the picam from recent show and tells

[bitter valley]

Picam?

[plain stream]

I don't know if there are links. but a google glass type thing

[eternal maple]

I'm tempted to try one of these for a scrolling alphanumeric heads-up display. Since you can send raw segment data to it, it should be possible to program it to display a mirror image that reflects correctly on the back surface of the visor.

https://www.adafruit.com/product/3127

[bitter valley]

I'm not looking to make a functional visor though. Right now I just need to settle on a design that I don't think looks like crap... like... ok, in a nutshell, here is what I am going for: http://promo.na.leagueoflegends.com/assets/dj-sona/img/DJSona-Wallpaper-Concussive.jpg

At least that's what I was going for, and now I'm not so sure if I should set a goal that lofty.

[eternal maple]

Update to earlier post: just tried the alpha display and a run-of-the-mill piece of 1/16" plexi. Worked very nicely. Display brightness was sufficient for a clear image. Without optics, placed the display close to my ear to get some distance from the back of the plexi. Projected the image about 6 inches in front of the visor. Hmmm.

[bitter valley]

B34T-S, online and ready to rock.

[feral acorn]

[bitter valley]

And the good part is that I agree. :)

Uploaded video of it working yo the characters Facebook page.

Now there's a show & tell for ya!

[umbral fog]

So, I'm working on making my credvault pretty (bcuz everything should be pretty in some form or fashion) and I've got bootup to where I'm actually pretty happy with it

plz ignore laptop desperately in need of a bath...

[sterile zephyr]

It's that time of year here in California, when smells are so pungent and tenascious you know someone is happy. 🍃

I'll be using this for admiring trichomes on plants without disturpting their photoperiod.

[clever pebble]

@bitter valley check how google glass have done visor if that helps

[vernal ferry]

@umbral fog ooh nice! Which libraries did you use for the display UI?

[umbral fog]

Just the standard adafruit gfx lib

the fade effect is actually PWMing the backlight on the panel

and the really cool little animation for drawing the lock was COMPLETELY BY ACCIDENT because using the native drawing primitives, that's how it comes out

[vernal ferry]

@umbral fog great use of the backlight! looks smooth!

@umbral fog is it complete?

[umbral fog]

nope, I still need to work on the encryption bit, and load from SD

but it is functional

[clever pebble]

@bitter valley also check Johnsons systems thermostat what have acrylic with touch

[umbral fog]

@vernal ferry i've been using it at work for a month-ish

[vernal ferry]

@umbral fog awesome, practical too 😃

[umbral fog]

Yup... now if only I could find a way to put an RTC in here that didn't require er-designing the world, or making a new case.....

[bitter valley]

Got an awesome idea for my next piece. A common name for Amalgams in Utopia Descending is "golemborn," so I want to laser etch אמת and מת ("emet" or "truth" and "met" meaning "death") and incorporate it into my costume somehow.

[ionic spire]

that sounds really cool

[ionic ginkgo]

question, how do I know if I am selected for Show and Tell tonight as I think I commented on the correct Google+ post?

[woven dagger]

I think if you joined in you should be able to see that you are in the circle

So what exactly is this chat for?

[ionic ginkgo]

I followed Adafruit on Google+ and commented on the post as the instructions said but I haven't been notified if I've been added to the Show and Tell circle, so that is why I was asking. Thanks for any help you can provide.

[woven dagger]

Here ill check the post

I think you were added in as you were the first to comment as far as i can see

Maybe you didn't just get the notification

You're Andrew Breiner, right?

[ionic ginkgo]

correct

[lunar trout]

The notifications come out right as it is starting...

[woven dagger]

I don't think there is anything you can do except wait until the message gets sent out

okay, im editing it a bit right now, so it restarts unless you actually get all 10 right then you have to manually reset it, so you can show it off

[clever pebble]

you hack it?

Here's something ive been working on this weekend. Takes an old xbox controller and adds a feather Bluefruit. Now it works as a Bluetooth keyboard. Also has a status light if battery is low

All buttons can be set to whatever you want

The big red has 4 directions and center press

I was going to use an old Directv remote but that one is a matrix and haven't got to mapping the matrix out yet

think if you have poll so you could even use it for that hehe

[lucid bloom]

Hey all

[clever pebble]

my weekend plan is to put this https://store.docker.com/images/nanoserver to my Raspberry Pi 2 or 3 or both as those have windows 10 iot core and it support in the version i have so trying python to that nanoserver as well so i can put rosie to it

[lucid bloom]

👍

Verizon gave me a jetpack 4g hotspot so PiGlass is now portable

And I got the mic working

[mystic ruin]

Hi @lucid bloom you could nearly join the show tell and from the PiGlass 😃

[calm sparrow]

Just soldered the headers on my HUZZAH ESP8266. Recorded all the action too, haha https://goo.gl/photos/fkrizYaSvv1jbf8F9

[lucid bloom]

I'm gonna live stream during show with PiGlass you will like it

I have to screen share to do it

[mystic ruin]

you seem to suffer from the same condition as me @calm sparrow , SSH, shakey solder hand 😃

[calm sparrow]

Haha so true @mystic ruin !

[mystic ruin]

actually you are getting more comfortable with each pin by the looks of things

[calm sparrow]

Yeah, it steadied eventually.

[lucid bloom]

I can watch YouTube on PiGlass too ;)

[calm sparrow]

This was the first time I've recorded myself soldering, so I was also nervous

[lucid bloom]

Always is tough the first time

[calm sparrow]

I have to solder the headers on my Pi Zero W in a sec too

I didn't have any live views the last time. Maybe I should switch to Twitter, twitch, or YouTube

Or even periscope

[mystic ruin]

Just a note, its hard to tell but it looks like some of your pins are a little light on solder

that the solder joint is only on one side , maybe the second and third pin you did for example

I might be seeing that wrong though

Shoot in Landscape if you can 😃

[calm sparrow]

Thanks for the tips @mystic ruin !

[mystic ruin]

haha, that dyno

[calm sparrow]

Lol I was like wait, what?

[feral acorn]

Why does dyno do a quick public warning?

I don't get the purpose of that

[mystic ruin]

i guess to clean up the chat afterwards

[feral acorn]

Not like we need public shaming etc

[mystic ruin]

true

[feral acorn]

Dyno is ultra conservative 😃

[calm sparrow]

Was it the accident space followed by the word light?

I dunno what triggered it

[mystic ruin]

I guess it was the verb you used for recording the video

its the same as using a weapon

@rustic stag is there somewhere to add suggestions for words that don't belong in the swear filter?

[calm sparrow]

Oh it deleted my comment about Instagram live video not being good

[mystic ruin]

I didnt even see that one!

[calm sparrow]

I said s u c k s

[lucid bloom]

Lol

[calm sparrow]

How is that even bad?

Lol

[mystic ruin]

[feral acorn]

yeah, I got censored for using c_appy

[lucid bloom]

Vacumms do it

[mystic ruin]

I said I was a s ucker for something and it got me

[feral acorn]

I think Phil said he planned to tune it up after awhile

[mystic ruin]

it's kind of dissorientating when it gets you

you nearly need to take out the thesaurus

[feral acorn]

yeah, but I'm all in favor of keeping this a very kid-safe place

[mystic ruin]

as I can never think of another way of saying stuff

[feral acorn]

yes, it is like a game at times

[mystic ruin]

I'm all for that too, but some just dont belong

[feral acorn]

y

[lucid bloom]

Start saying Pokemon names instead

[calm sparrow]

Oh well, lol.

[mystic ruin]

But I dont even want to curse 😃

(not here i mean)

[calm sparrow]

I added solder to the lacking pins @mystic ruin

Now I'm going to solder the headers on my Pi Zero W

[lucid bloom]

For dinner tonight....

[calm sparrow]

Looks delicious @lucid bloom

[lucid bloom]

Thanks

Adafruit is supposed to publish my how to soon

Then I can do the upgrade guide

I have bluetooth music, music via mpsyt and YouTube streaming

I ditched the keyboard for my phone to control it

This is a pic taken with the PiGlass camera

Just live in the county side!

When I was in NYC (10 years ago) I was with AT&T, and they were awful

I could make then look more steampunk with different frames @feral acorn

I just got notifications from PiGlass to my phone with simplepush

[lucid bloom]

@rustic stag I got a new toy for free, it's a 7bot so expect to see it some time soon

[rare frigate]

So the otherday I found this site http://vtol.cc/filter/works/hotspot-poet and thought hey thats a perfect fit for a feather huzzah

the code was super simple, next on the list is an enclosure to hold the feather and a cylinder battery. Not sure on the range yet, if needed i got a feather M0 wifi also with u.fl connector. Could probably easily be done in circuit python also

Thinking of putting this in my bag for at makerfaire and see if anyone notices and have a secret meet location

[mystic ruin]

Thats super neat. The orginal was also done on an ESP8266 too

Cool idea

[mystic ruin]

I'm messing around with table center ideas for the wedding and I saw this pretty cool frosted white lamp in ikea for €5 last week. I added a 16 neopixel ring to the bottom and I think it looks really nice for how simple it is

The lamp insides doesn't even come attached so there is nothing to remove

It has a hole down the bottom for wires and everything!

The glow is a bit brighter in person

[lapis jasper]

looks good @mystic ruin !

[bright hull]

philb has a good guide on creating candle effects

https://learn.adafruit.com/circuit-playground-jack-o-lantern/how-does-it-work

that might look neat in there

[mystic ruin]

Thanks @bright hull !i was wondering if I could achieve it with something flat like the pixel ring

Thankfully smarter people than me have already figured it out 😂

[bright hull]

well, it's not flame shaped. just produces changing light intensity like a flame does.

if you want something that looks like a flame shape, then, yeah, might be tough with just the flat ring

but with a charlieplexed matrix...

https://learn.adafruit.com/animated-flame-pendant/overview

[mystic ruin]

No the light intensity would be perfect

Also thanks @lapis jasper

[lapis jasper]

np 😃

[solar yew]

@mystic ruin I've been doing a lot with candle animations lately. Including with Neopixel rings.

16 is almost overkill... in fact, I'm building a fire effect using just 10 on the playground....

Someone just pointed me to a nice 4 pixel effect:

I also ported one of the candle flicker routines from c to circuit python (classed animation, so each pixel is independent light)

I'll share that, still exploring what I can do with it...

[mystic ruin]

That's great thank you @solar yew

Went to my Family Reunion las weekend in the Upper Peninsula of Michigan. I 3D printed the UP and placed an LED and coin-cell in the back of it.

[lucid bloom]

It's alive and moving now

@lucid bloom Nice arm. What kind is it? I have a uArm Swift Pro. These things are a blast.

[lucid bloom]

7bot

[shut sigil]

Oh right. Very nice product. Almost went that route.

[robust fiber]

Oh hey @mystic ruin thanks for the frosted lamp post I was just looking for something like that!

[clever pebble]

haha dont worry just funny seeing ikea pushing weird swedish words around

[robust fiber]

Thanks!

[mystic ruin]

@wet mulch does kalax (maybe two L) have any meaning

Cause I think my girlfriend loves them more than me

[wet mulch]

its a village in northern sweden

https://en.wikipedia.org/wiki/Kallax

basically white walker area

321 inhabitants

[mystic ruin]

I knew she was the army of the dead

[wet mulch]

haha

these are actually quite nice

ikea is actually quite good at selling their products, always looks so nice and clean

[mystic ruin]

This is what mine look like

I don't think they would sell aswell!

[wet mulch]

haha

thats true for the most cases

it looks really nice on display

[glad roost]

In the US, KALLAX seems to be being discontinued. It's marked down "While supplies last in participating US stores.". I bought a small EKET unit a few weeks ago. Not sure if it's supposed to be the replacement -- it's sized differently.

[mystic ruin]

Oh no!

I think my girlfriend would be devastated

[robust fiber]

I love the table system of ikea. The white tops are perfect for taking photographs of boards

[feral acorn]

Yeah, we bought one of their tables for the kids’ project room

The thing is rock-solid. I think a couple of full sized adults could jump up and down on it and it wouldn’t even flinch

The small ikea desk we bought for the kids is a different story. Kinda flimsy and the top delaminated pretty easily.

[robust fiber]

@mystic ruin I see your GRÖNÖ and raise you my TVÄRS.

There is a little disassembly required though, Had to pop out the lampholder by unclipping it.

It is quite gorgeous when run with a fading Neopixel animation. Add a IR phototransistor and you got an automatic night light.

[mystic ruin]

Looks great @robust fiber

Nice UK extension lead too 😂

[rustic stag]

ok minimal dock kit, works good, and testing a 3rd party controller and playing with a knit amiibo

there was candy in the mushroom thing, but we ate it

mosfet the cat will get the amiibo later

[buoyant breach]

That's awesome!

[rustic stag]

we're trying to see what/if nintendo mod stuff we might do

glowly neopixel docks, 3d printing, custom controllers, etc

[buoyant breach]

That would be so cool! I would love to make a glowy dock/controllers

[rustic stag]

yah, it has USB and all that

so easy fun mods anyone can do

add a trinket, etc

circuit python

@lapis jasper the aiimbos that are knit make ok cat toys

and you get a suit in mario kart

MISTAKES WERE MADE, IT IS OK 😃

[stable plover]

I've got a backlog of mistakes, where shall we start? 😄

Granted it wasn't an electronics mistake but just this morning I tried to edit a file with "vlc filename.c"

[clever pebble]

Zoidful mistakes?

[vernal ferry]

where there's smoke there's !

[clever pebble]

by mistakes we learn?

[stable plover]

Oh I put a prototype Button SHIM on backwards a couple of weeks ago - for the second or third time - and this time instead of burning myself savagely I let out the remainder of the blue smoke from the tiny APA102

It was extra funny because I put it on with the Pi turned off for a change

(the prototype was revised to make this particular explodey fun impossible)

Oh and the Tingbot guys sent me one of their few prototype Tingbots to try out, I tried to fit it with a speaker and accidentally left it loaded so it melted itself into the plastic casing... I had to pry it off, put a little sad face sticker on, and admit to them that I stuffed up on their precious prototype 😄

[bright hull]

it's not a mistake. it's invaluable experience.

[gray inlet]

A few weeks ago, I learned that tantalum capacitors are polarized. #sparky

[versed bridge]

i found out my 3d printer has a selector switch for the localised voltage. turns out that when set to 110v my 230-240v supply popped the board!

When using the snap block connectors remember that all pins are connected. You cannot put the two positive wires together in one opening and two negative wires together in another. You will ruin your fona board the day before project due date. #sparky https://www.adafruit.com/product/874

[normal zealot]

One of my more epic print fails (started fine and overnight came back to see this) #sparky

[vernal ferry]

@normal zealot did you figure out what caused the failure?

[normal zealot]

@vernal ferry Yep. The model was this: https://www.thingiverse.com/thing:1791235 printing for a friend who bought 1.75mm filament even though my Lulzbot TAZ6 officially should only run 2.85mm filament. The bottom printed fine but part way up the very thin shield a layer didn't glass/bond well and it blew up as you saw. So the fix was some further refinements to the printing profile when we run 1.75mm filament through the machine

@vernal ferry but the next attempt came out great as you can see here: https://twitter.com/TinWhiskerzBlog/status/884862511845183488

[rustic stag]

wow the #show-and-tell with the #sparky stuff is working out great, thanks everyone

[rare frigate]

I got the led lantern a while but didnt like that it used 8 d size batteries

Took it apart tonight and found that it makes two 6v supplies and makes them parallel

The brightness nob then sends the voltage through the resistors in series. And depending where its turned is the resistance

Now to determine the current and see if an alternative power method is possible

[rare frigate]

Looks like theres also two 1ohm resistors on wires to leds. Parallel too

[vernal ferry]

My most recent #sparky with a sensor that had poor contacts and went smokey..

[robust fiber]

#sparky I flipped the positions of a capacitor and a 0 ohm resistor for my first smd board because I was reading it upside down, resulting in a short from 5V to GND. Took us an hour to figure out why the voltage along the power rail was 0.6V. Sparky made an appearance early on, but I thought it was just a trick of the light.

I met Sparky the Smoke monster when I misread the spcs on a 9W RBG LED, and instead of the 2v forward voltage on the led, I applied 5v. OOPS! ANd poof, there it went. It was already glued in place on my project, and I had to wait a week for a replacement. 😦 Yep. It happens to all of us!!

[shrewd warren]

Not a smoke fail, but a fail because of something electronic I made 😃 my automated plant grow system borked and flooded my test plants https://youtu.be/QPbKujlxRXs

so we triggered the error that happened on show and tell last night, but he didn't even notice. I think russ is too oblivious to be messed with.

[plain stream]

there may be a bug in the speaker library changing the volume back to "quiet" so I made a field hack and set it to 1 manually before each play. it's much louder and he's definitely noticing now

[ionic spade]

Hey all - wanted to share that my CP + Adafruit004 setup worked today ... failed during 8/30 Show & Tell (and that was my first one too ... sad). Anyhow, for #adafruitextracredit and #circuitplayground I posted a video on my FB page showing what it was supposed to do and wanted to share:
https://www.facebook.com/UncleMoki/videos/1490841077630395/

[ionic spade]

Like Sigafoo's prank ... we used to hide french-fry timers in the ceiling tiles when I worked in fastfood. We'd set them to go off AFTER we left and then watch the closing manager try to find it. Ah, the good 'ol days.

[calm sparrow]

Solar LiPo charger.

[feral acorn]

I’ve done exactly that 😎. I got practical experience in the effectiveness of my glass windows

[frosty tusk]

@rustic stag #sparky Made a stand for this awesome little soldering iron.

[vernal ferry]

@ionic spade cool 😄 what fixed it?

[ionic spade]

@vernal ferry To get it to work for that video, I powered the CP and Feather separately, each over USB. I really want the setup to run off of a single LiPo or LiIon plugged into the Feather so the Feather can act as a charger when needed. I had success powering the CP from the Feather's 3.3v pin to the CP's JST. The problems started happening when I added code to light the NeoPixels. I integrated the mic_fft example which normally flashes brighter with louder/higher frequencies. The crashes happen most often with loud and/or high-frequency sounds that make the CP light very bright so I suspect the NeoPixels are causing a power fluctuation or something and that's causing the CP to thrash. I wish I had an O-scope (and a friend who knew how to use one 😉 ) so I could see what's going on. Right now I just have my multimeter. I have a few ideas on what to try next ... write my own NeoPixel show with less intense/active lights ... TRY checking for current and/or voltage fluctuations with the multimeter and if confirmed, add a capacitor somewhere (just wich I knew where and what size) . I hate to admit it but I feel I'm close to the limit of my current skills/abilities 😖 ... I'm just not quite ready to give-up.

[vernal ferry]

@ionic spade have you looked at this learn guide? https://learn.adafruit.com/dma-driven-neopixels not sure how related but thought this when you were describing issues

[ionic spade]

@vernal ferry Thanks. I actually did try to read through those because initially I was going to just add a small NeoPixel jewel, until I realized I'd run out of GPIO pins on the Feather+MusicMaker setup. I don't think I'm having the types of issues that the DMA driven solution solves because my CP is literally just running the mic_fft example from the Arduino Circuit Playground library ... and only a few additional lines of code to simply set the CP's GPIO high or low based on the buttons and switch status . That mic_fft example never gave me problems. And it works in the video I posted. It's only when I try to power everything off of a single power source that things get weird. Although it also works when powered from a single power source IF ... I remove the mic_fft example too. Hmmm ...

[vernal ferry]

@ionic spade do you know how much power all of everything is drawing?

[ionic spade]

Not yet but that will be part of this weekend's troubleshooting. The Adafruit write up for CP and for the Feather Huzzah ESP8266 warn that the regulator can handle a max of 500mA but not continuous so budget 250mA. CP Lesson 0 actualy says to keep it at less using the calc 250 /(Vin - .3-3.3V) so 178mA for a 5V USB: https://learn.adafruit.com/circuit-playground-lesson-number-0/battery-jack-and-supply#output-current

[mystic ruin]

@ionic spade do you have a level shifter? You could use the 5v pin (assuming there is on on a cp, could be called vin)

[rustic stag]

MORE SOON 😃

[glad roost]

@mystic ruin

@ionic spade The VBATT pin on Circuit Playground is USB or battery voltage, whichever is higher, minus a Schottky diode voltage drop (0.3V or so). On Circuit Playground Express it's labeled VOUT.

[normal zealot]

I've been thinking about making an outdoor weather station powered by a small solar cell like what @calm sparrow shows up and that lipo charger but I live in NH where it gets cold in the winter and AFAIK once we get below freezing it is not good for the lipo. I bet other folks on this forum have already solved that sort of thing for this sort of climate? Any suggestions? Simplest might be remembering to take the lipo out around the time of the first freeze and jsut deal with station only running during the day or looking into using a super cap instead.

[glad roost]

@normal zealot https://electronics.stackexchange.com/questions/1669/cold-weather-battery-power esp last answer

This would be a good question to ask in the forums.

[mystic ruin]

You'd be surprised how much warmer something like a feather huzzah would be in an airtight container like a lunch box, maybe you can see if that would keep the temp up enough

[solar yew]

@normal zealot hey, we should do a NH meetup

[calm sparrow]

@normal zealot I've seen some pretty creative solutions for cold weather and batteries. If you do house the circuit in an enclosure, the heat from your circuit might be just enough depending on the project.

@normal zealot here's the @rustic stag product ids for the LiPo and solar panel:
1 x USB / DC / Solar Lithium Ion/Polymer charger (v2) [ID:390] = $17.50
1 x Large 6V 3.5W Solar panel (3.5 Watt) [ID:500] = $39.00

[normal zealot]

@calm sparrow yep, thank you. My project is a microbit + climate kit/weatherbit (from sparkfun) which whould be fairly low draw and I don't think will generate enough heat for the subzero months up here. I want to see if I can rig the BLE on it to bream the results to something back in the house etc so there might be a periodic higher power consumption but not that much. The front-runner is just taking out the lipo after the first frosty night and just letting it run during the days, going the super-cap route (need to read more up on that) or maybe both

my complaint with that board is it has the humidity/pressure/alt sensor in the middle of the daughter board and the folks at sparkfun suggested simply drilling holes into the enclosure but I don't like that idea as I think too much moisture in the air will eventually corrode the electronics

so either I have to 3d print something to give a rain resistant tunnel of air to that sensor and keep the rest in air/weather tight parts of case or forgo the accurate use of that sensor

@glad roost Thank you for the link, I'll check it out. (I hadn't been to that particular forum before)

@mystic ruin yea for other projects I've found that to be true. For the microbit it doesn't generate much in this usage. 😦

[glad roost]

@normal zealot I'd also suggest asking in https://forums.adafruit.com.

[normal zealot]

@solar yew yeah that would be fun. I'm in southern NH (greater Nashua area) are you in the same part of the state?

[solar yew]

@normal zealot I'm central, near Concord.

So pressure is a maybe but if you seal the device against moisture, you won't get humidity reading, of course, ice would be a factor too.

I agree, a energizer lithium rated to -40 is probably good. Make device alert you if temp drops close to that.

Humidity at zero temp is kinda pointless anyway, I'd think.

[clever pebble]

actually it's not

[solar yew]

https://electronics.stackexchange.com/questions/90385/using-an-arduino-in-below-freezing-temperatures also worth considering (should apply to microbit similarly)

Condensation is raised as concern too.

@clever pebble in a device spec'd to handle it, yes... in this case?

[clever pebble]

in cold if it operate with battery you need to capsulate it well but also remember it dont heat too much

if you consern condensations then those connection points you could protect so the condensation water dont do damage like shortcircuit stuff

there is a material what can protect from heat and cold

the material is gel like but can keep the outside heat out

[normal zealot]

@mystic ruin are you in the New England area as well?

[normal zealot]

@solar yew @clever pebble thx for the links. The kit I was given is this: https://www.sparkfun.com/products/14217 which I was really excited about but to me it seems like the folks who made it never deployed one into the real world or at least not for a long time. It looked like a great /fun set of sensors and is described as needing to be mounted 12 +ft in the air for proper wind readings. But the ground temp and moisture gauge cables are a couple of feet long (That eas easy enough to fix). On the weather:bit board (right in the middle 😦 ) has the temp/humidity/pressure/light sensor in the middle of the board so to me the only way to expose it would be a small rain shielded tube with gaskets to try and protect the rest of the electronics in a water proof case and figuring out a way to 3d print some water tight cable glands etc. AFAIK it was designed and built out in Colorado which I assume has at least as harsh a winter as I do. And if I am mounting this thing up on a tall pole I don't want to replace AAs often as I assume the BLE transmitting of data back to the house will require a level 6 or 7 setting for the BLE power and presumably draw a lot more power than a system just logging data to SD (again which would be hard to retreive). To me the value in this sort of rig would be in transmitting data back to me in the house so it can be uploaded to wunderground or similar. That's why I've been looking at a solar panel + lipo or similar as a way to keep this thing powered indefinietely but as we've all discussed the temperature range presents some interesting challenges. The SF tech support answer was to just drill air holes in the bottom of a case but to me that would let too much moisture into the electronics and prematurely degrade the system .
