Hardware Posts – Hack Club Scrapbook

I made a PCB for the first time :D I've always wanted to make one before but it's always felt really scary and complicated to me but yesterday I decided to give it a try and do something for solder to learn how to make one and for something I'm hoping to do later this month. It's a pretty simple circuit that basically lights up an led when you press the button. It doesn't do much but I'm really proud that I was actually able to make something and that it theoretically works. Need to decide what I'm going to actually make for solder though

(Couldnt get a new photo 😭) worked more on my prototype (and soldering skills!!)

Finally got my soldering stuff so i took out the prototype of my project, rewired it and schtuff. Awesome sauce!!

hi, i’m guac and this is my first scrapbook post! i just did scrapyard austin and i feel wayy more inspired to actually code things instead of just… breaking them. i like Python and Java like a basic bitch, but i’ve also been using C# and .NET for a school project and oh my god it’s like if you could actually make GUIs in Java… anyways i bought a kick-ass little $30 ESP-32 demon that has some DANGEROUS capabilities, and i think my next project is to write some firmware for a hardware cryptography module i bought for it!

For my first day of #C045S4393CY|, I worked on getting #C07F3EA2L8G| to stop buffering! I lowered the stream bitrate and tweaked some FFMpeg parameters while live on YouTube and learned that low-end Hetzner dedicated servers don't like Intel VAAPI hardware acceleration

Despite that, I was successful, and the stream no longer buffers!

today I finished the code for my arduino pong game and am wokring on making a lego case for it!

https://scrapbook-into-the-redwoods.s3.us-east-1.amazonaws.com/43d64deb-53db-44bd-bdfb-859ee4a7f8ef-image.png

Optimized game code and added some level of hardware acceleration to reach 400 fps with floor and wall rendering.

today I worked on a pong game for arduino using a dot matrix display. My arduino's analog pins might be broken though, as the potentiometers are not reading, but a simple circuit with them and a light works perfectly fine 😞

I completed my first full PCB assembly using a PCB I made. The PCB I created it a re-creation of the stock one used for my 3D Printer that I added some new ports/connectors for, all without the original PCB files. I used both leaded solder and bismuth solder paste, this was my first time using solder paste and first time working with bismuth, I found bismuth's melting point to be excruciatingly low since the 4-layer PCB had so much thermal mass. Here are some photos I took along the way, lmk if anyone has questions.

[making for #C07NUNPGEU8| and bin] initially spent time (~2 hours) making four 88 led matrixes in a chain display words using the raspberry pi pico by coding in micropython. changed to a single 88 led matrix because of bin requirements but you can still display whatever you want and the words in the order repeat indefinitely. will be adding complexity in the future as i read up further on hardware wokwi.com/projects/409701390916206593

Today I am tidying up and cleaning my arduino kits, I have a lot of modules so it will take a while

update on a drone side project i've been working with @GlenMue (haven't shared updates in a while, cuz it's actually hard, lots of hiccups along the way, this is my first hardware project and... well... life has been lifeeeinnngggg 🌦️) 1. got most of the firmware implemented and the PID controller 2. got one of the propellers broken during a test

- we now need to get a new set, haven't found any yet in shops around (hopefully won't have to order online) That's all I've to share, gotta get back to work Linked a video to showcase the work we've done so far

I always had a lot of arduino RFID modules to solder, today I decided to solder them one by one

The second robot is done! I am so glad I got to finish this - thanks HC for giving me a reason to learn robotics (and learn how to solder)! I'll definitely revisit this project and make it better later! (2/2 - Follower-Robot is done!)

Some weeks ago I made a push counter for an esp32 in order to receive it for the bin, then I discovered that the custom fee was €23 and then I decided to buy an Arduino, so now I've had to make the old code for esp32, Arduino compatible, and so far is going great github.com/Rayanlupo/push-up-counter-for-arduino

iCE40 DevBoard · A simple development board design for the iCE5LP2K-SG48 FPGA. I needed to learn how to make FPGA board for a future project (a VGA GPU for my breadboard computer), so I tried making a devboard. Chose the cheapest one that has enough block RAM: iCE5LP2K. There are many issues with the board - no 5v/3v3/GND on the headers, some mistakes in the schematic and other stuff. I couldn't even get the FPGA to configure (maybe fried it during hot-air soldering?) and don't quite have time to debug it/order a new one, so more updates at the GitHub repo I guess.

Made a library for both arduino ide and micropython for controlling motors. Github Link: github.com/Ahnaf-nub/Motor

I made a robot for the very first time (thanks HC for giving me an excuse to)! It's an autonomous maze-solving robot (a Micromouse!), made using an Arduino UNO R3, an L298N Motor Driver, a pair of DC motors and three ultrasonic sensors! It uses a very simple left-wall following algorithm, and although there is a lot I could do to improve, I believe this is good enough (for now, atleast!) I'll try to revisit this sometime in the future, and maybe experiment with more complex algorithms like floodfill! GitHub Repository: github.com/deoshreyas/Micromouse
