joined max's #onboard call and built a little "fire spitting" orpheus, you can control the intensity with a potentiometer on the back. i'm working on getting the board to use Fr4 material in the fire part so the led light can shine through :)

I designed the anti-flux chip for your macbook. Flux dims the screen to help you stop using your laptop when you should be going to bed. My board rumbles when it detects light, discouraging laptop use during the day.

day 10 of #10-days-in-public. after a short design sprint v0 of the mechancial keyboard pcb is done. it's not my best work, and will probably get iterated more and more until i'm happy with it, but i'm pretty proud of what it is so far. thank you for @Aram for the challenge, which pushed me to actually get off my butt and design it haha!

Day 5 of #10-days-in-public! Today, after being very confused with some circuit diagrams yesterday, I learned a lot about PCB design for my project (so I can design a better PCB). Bulleted below are the main things I learned; • Electrical planes - Layers in the PCB (typically made up of some of the planes described below) ◦ Ground plane - Good for shielding board's more sensitive electronics ◦ Power plane - Good for distributing power, but also help shield signals from one plane to another ◦ Trace plane(I am sure this is the wrong name) - Plane with actual circuits with the traces you make • Vias - Holes used to connect one plane to another (typically a trace to another plane) • In line resistors - Reduces compassionate in outgoing signal lines so there is less noise • Zero ohm resistors - Often used to connect two surface mount pads for parts of the PCB that does not need to be connected but can be later On a separate note, during my procrastination, I started experimenting with shading in custom polygons in Blot. Right now it does not look the best but I hope to improve it!

Day 3 of #10-days-in-public Today I had two big accomplishments. My goal is to program a receipt printer to print a receipt every time someone wins a Sprig, OnBoard, or Blot grant onto my desk so I can read about their project. The first accomplishment is that I added code to find OnBoard pull requests from GitHub usernames, download the project descriptions, and use tracespace to render SVG board previews onto the receipts. See below for a screenshot of what this looks like (it’s a screenshot of a subset of a PDF that is sent to the receipt printer - this is all publicly accessible data from the OnBoard repo). The second accomplishment is that I flashed a Raspberry Pi to start getting this thing to run headless! This is my first “real” project using Python, and I’m starting to feel a lot more comfortable using the language - which has felt awesome! I am so inspired reading about everyone else’s projects! github.com/hackclub/hack-club-grants-receipt-printer/commit/0030c42c7c0909a34ccb7ac2709b2f03ff374845

for #10-days-in-public I’m making some tutorials around making a PCB. Before I’ve made a video about a specific part of the process but now I’m going to make a video about the process end-to-end, from idea to finally ordering a usb-a to usb-c converter

Day 3 of #10-days-in-public I fully decided I will use an arduino nano after researching in the hopes of it being lightweight enough for servos to hold up. I started on the pcb design and it will most likely end up looking like this:

Day 1 of #10-days-in-public! Today I started researching a driver chip for my calculator themed development board. After asking the folks of #onboard what chips they used in their projects I ended up deciding(for now) to use the RP2040. The pro's for this chip is that it is made by a credible company(raspberry pi), it has 30 general purpose IO pins, 4 of which can be used as analogue inputs, it's low cost($1), and it has loads of documentation. The con's(I have found so far) are the 3.3V logic level and lack of built-in wireless connectivity. I am currently thinking of possibly adding on another chip to use with it. I also started taking apart my calculator to figure out how it work, may keep digging into it tomorrow.

Day 1 of #10-days-in-public! I arrived home late due to track, but got to work on learning pcb design! I followed the hackercard from #onboard and it was really helpful it getting me used to the software! I will be experimenting more, but here is my finished schematic for day 1 I think i put in a wrong component so ill fix that lol

It's been a while since I've done a full update on the E-Fidget, so here it is: Version 4 was funded by #onboard, and it didn't quite work out (assorted issues with wiring and the relay-as-haptic-feedback idea) Version 5 was sponsored by PCBWay, and worked quite well with a linear resonant actuator for haptic feedback. Version 6 was a minor revision, with just a few tweaks. Version 7 added rechargeable battery support, but used an obscure, hard-to-source battery and was too expensive to sell easily. Version 8 was a complete redesign, following the same shape, size, and look of V7, but using a different microcontroller and a more common battery. It's still on the way! Now, everyone's favorite part: Pictures! Black is V4, Purple is V6, Blue with the big logo is V7, and other blue is V8!

Electronic Piano PCB ordered! Jam coming soon™. The gold/silver/circular pads are surfaces connected to capacitive touch sensors (they detect your finger by how it forms a capacitor with the circuit). I have different layers on those to experiment with which finish works best for touch detection in this design. But whenever each key detects touch, it allows the capacitor of the 555 timer (a frequency generator) to be charged at a rate determined by the variable resistor for that key (the potentiometers are at the top). Those potentiometers can be tuned to allow for different frequencies for each key. Then, the 555 timer outputs a signal into the speaker circuit, which you can then hear! What are your cool name ideas for this PCB? The best suggestion gets to be the jam title!

day #3 of #bci! today was definitely more goal-focused vs. more research-focused over the last two days: finish the pcb, get a pcb bill of materials, have a meeting with 1517, and continuing to finish my attempt to explain what we're doing. today was another great day ( ;) yes i've said that over the last two days because it has genuinely been so much fun): i spent the first half of the day getting a bill of materials using the jlcpcb plugin on kicad (cost for 2 assembled boards: ~$300), then spent the second half of the day working together with @Cheru to design the usb to uart converter for transferring data between the microcontroller, and of course, an amazing meeting with this really cool guy from 1517 fund who gave us some great advice that we spent like an hour talking about. unfortunately pcb is not done but i'm going to do a lot more work on it tomorrow so we're on track to finish on friday! (the trick is referencing like three datasheets/schematics at any given time.) sadly don't have too much notes today but here is the short draft of my attempt to explain what we're doing: cloud-d4hdmkpwy-hack-club-bot.vercel.app/0bci.pdf (this is part of #100-days! join us over there, we're working on cool stuff like #something-on-a-bus-this-summer and #toriel-dev!)

This is a 555 timer driven speaker, and the RC on the 555 timer charges up at different rates (the Timer label) based on which 'key' is connected. The keys are the individual boxes, each of which has a capacitive touch sensor IC that connects its potentiometer to the 555 timer label, which then charges up the RC based on the potentiometer value (the speed of charging changes the frequency). Basically a capacitive keyboard.

day 2 of #bci! today my goals were to get the hang of using kicad, understand the schematic of openbci's cyton board (which is, along with hackEEG and piEEG, the basis for a lot of our understanding of what exactly happens in EEG boards) and spin up a bill of materials for everything going in our pcb. i got to the first two and didn't do the last one (although i will eventually get to it!), but i had a lot of fun! today was another great day because this is the most fun i've had in a while building shtuff (among other things: deciding who would be who in the openai drama, the f*ckboard, dinner at steve). tomorrow's goal is to spend the whole day just building the actual pcb (and then spend thanksgiving off?) we're building this out in the open so my daily notes are all here: cloud-ckujstd4d-hack-club-bot.vercel.app/0jc_0e4ee6c5e5e546ce910bda3e3ad2ac10.pdf (this is part of #100-days! join us over there, we're working on cool stuff like #apocalypse and #dallas-day-of-service!)
