@GB1140Have been trying to learn PCB design for the past two days and this is what I achieved and submitted to solder:
@iUnstable00Day 3:
I procrastinated on the neighborhood project again 😔
Yesterday was pretty packed tho. I did more research into Meshtastic nodes and decided to go with Femtofox! Their hardware looks solid, but sadly they’ve got this proprietary “Pro” edition that has extra features compared to the open-source one. Tbh I wouldn’t mind supporting them and paying for the hardware, but they’re out of stock 😭 The difference isn’t that huge though, so I’ll probably just roll with the free version and pay for PCB manufacturing myself.
I also got an automatic water dispenser for my cat recently, and it’s really annoying. It allows only a maximum of one water refill every 6 hours (drains the old water and pumps in fresh), but the waste bin fills up in just 2 days... For something that’s supposed to be convenient, it’s kina not 💀
My first idea was to just manually power it on, press the “refresh” touch button, and turn it back off. But that defeats the entire point, it would honestly be faster to just dump out a normal water bowl and refill it by hand.. So I cracked the device open, soldered a wire to the capacitive pad that triggers the manual refill, and tested it by shorting to GND, and it worked! Now I just need to hook up a microcontroller to simulate that GND trigger, and maybe add a relay or transistor inline with the battery to control the whole thing automatically :-)
@iUnstable00Day 2:
I didn’t get much work done on the neighborhood project today. Instead, I spent my morning recording a devlog video. Then, I helped a friend with his Proxmox container setup and did some maintenance on my home lab. After that, I got a bit distracted and placed an order on JLCPCB to manufacture my old project from The Trail. I broke mine during the hike, and I wanted to show my parents what I built and keep it as a souvenir. 👀
Then, I got inspired to run a local Meshtastic node in my town and connect with another friend. I’m going to meet with him tomorrow and give him the hardware since I already have some leftover from the early prototyping of my Trail project.
I don’t think I’ve shared pictures of my home lab yet, so here they are! (I took them with Project Indigo, my new favorite camera app I discovered today.)
@iUnstable00Restarting my scrapbook streak!
Day 1:
So today I continued working on my neighborhood project. I've coded for another 4 hours today after taking a week-long break. so now I’ve clocked in 12 hours in total!
I’ve made some great progress today. I've implemented the login/registration API and the JWT auth token issuing with a refresh token. I’ve also added custom GraphQL auth directive and token validation.
Tomorrow, I’ll start working on the frontend. I’ll be building a simple login and register page, and a 'hello world' dashboard when you’re logged in. I’ll also need to implement token refresh and rotation on the backend side.
I’ve also started documenting all my current and previous hardware/tinkering projects in my journal. I’m hoping to publish them on my personal website (which is still in progress). I never journal anything so all my work from when I was 10-17 years old has kind of gotten lost ;p
@Aadish0working on a shopping list app with collaborators(android and web release coming soon!)
@arav0I 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
@laith0(Couldnt get a new photo 😭) worked more on my prototype (and soldering skills!!)
@laith0Finally got my soldering stuff so i took out the prototype of my project, rewired it and schtuff. Awesome sauce!!
@guacmd0hi, 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!
@Micha0For 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!
@DynamicWhiteHat0today I finished the code for my arduino pong game and am wokring on making a lego case for it!
@AneeshS0Optimized game code and added some level of hardware acceleration to reach 400 fps with floor and wall rendering.@DynamicWhiteHat0today 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 😞
@DynamicWhiteHat0Today I worked on creating and shipping an arduino launchpad. It comes preloaded with 4 star wars themes and plays 10 notes.
@DynamicWhiteHat0Finished wiring and testing an MPU6050 with an arduino uno. Got it visualized, which was fun:
@Nathan0this is my x64 multitasking UEFI Operating System. I started it maybe a week ago, so I'm pretty proud of it. It runs on real hardware too! This is made in pure C, C++, and x64 Assembly, github.com/AzureianGH/AquaniteOS
@RyanDiLorenzo-U04JGJN2B400I 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.
@YeGao0Been learning more about PCB desgin as I'm kinda of interested in soldering my bin parts onto a custom PCB
@NathanTsai0I learnt that a potentiometer is impossible to fit into a breadboard, and connecting it is fragile. I also learned how how to use an arduino. github.com/nathantsai1/boredlights
@anne0[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
@EXELVI0Today I am tidying up and cleaning my arduino kits, I have a lot of modules so it will take a while
@JosiasAtHackClub0update 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@EXELVI0I always had a lot of arduino RFID modules to solder, today I decided to solder them one by one
@TawhidBinOmar0arduino flight controller in c.
Github@ShreyasDeo0The 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!)
@Jolomolokolo0After countless hours of tinkering, writing code, and testing with hardware, the DEEJ-Audio Mixer is nearly complete, but due to a lack of production facilities, the project must temporarily be put on hold until the right circumstances align.

@anne0tried to make a hardware TOTPkey and failed miserably because (1) the routing was crazy difficult since im not good at PCB stuff and (2) the firmware part legitimately made me cry. find it at github.com/arsoninstigator/hardware-TOTkey
@Rayan0Some 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

@Mirrreeek0iCE40 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.
