@kognise0"what the fuck is that soldering job?"
"what are you using 10 watt resistors for?"
well, you see, i like loud noises and electrical engineering. (despite sucking at it. but i didn't kill myself!)
pro tip: no better chassis for dangerous electrical projects than a tupperware box with external components gaff taped on :>
@belle0learning about the cpu! it's really fun but my brain hurts and i have so so much more respect for all the hardware hoomans :salute:
@ArcadeWise4omg omg i love embedded systems. here’s my arduino mega and pico transmitting data over a custom protocol I designed!
@meridi0Went to a CubeSat 🛰️ conference today, got to meet awesome people and check out their hardware! NASA was handing out some really pretty posters and swag as well, picked a lot of those up
@RachitAgarwal-U02SVBTUR1P0Made an automated Stone Paper Scissor Machine using 3D printer, Laser cutter and other elements(Arduino, Servos, etc.)
@zrl1I replaced the extruded in my 3D printer today! The pre-assembled extruders were all out of stock, so I had to buy the parts for one (which got lost in the mail, so had to place a second order…), put it together, and then pull out the old clogged extruder in the printer and replace it with the new one I assembled.
I've always been kind of intimidated by hardware and am really proud of myself for getting this done! + bonus sunset picture from tonight
@tetraoxygen0Made a Panic Sign client for the Playdate! (simulator, the actual hardware doesn’t have network calls yet)
@HenryBass-U02KEJ8T6D83First thingy with the leap. Built a little ultrasonic distance detecting circuit. So far it's stationary. next up is to hook this to a servo to get a 180* scan, to form an image (if I can figure out how to do graphics with the Arduino in real time)
@zfogg1Here's the secret project I mentioned, @hugo.y.hu935! i'm putting together something called....
✨ SAMBOX ✨
The Sambox is little box that has a computer you can SSH into and instantly hack on a project and deploy it, with custom DNS and zero setup :cooll-thumbs:. It has its own wifi router and everything. Just power it up and start hacking; you're good-to-go!
This Sambox will go on a journey. It's going to start by being mailed to a Hack Clubber, who will hack on it for a few days (until the timer runs out‽). We'll include four shipping labels with Sambox so that the first hacker can mail it to the second. The second hacker may change or customize anything on Sambox or contribute something new, and then pass it on to the third after the time runs out.
All hacking will be done OFFLINE on the Sambox :yuh:
The final person to get Sambox will be @sampoder of course, who will plug it into the internet, putting all of the projects online! :yay:
Here's the shopping list. Parts arrive ~tomorrow~ today!
@Devnol0Today I bought a UPS for my server and finally completed the first version of github.com/devnol/powerSurge, a raspberry pi pico-based dumb shutdown system. It detects when the power falls out and while the server is running on the UPS power, the pico pulls low the power button of the server, telling it to finally shut down safely and without loss of any data. In the future I plan to add a restart feature if the power comes back up after a specific amount of time and an ambient thermometer so that it shuts the server down if the temperature gets over the specification. If you have a homelab and like tinkering with hardware this project might be for you, so if you want give it a follow on GitHub to get updates on my progress on it.
@Rafi0Couple of weeks, I was working with ESP8266. to implement basic device registration process for IoT product. Finally I’ve cleared all my challenges. Learned MQTT, spiffs, and lot of string handling functions 😂. All this done by using esp-idf.
@Devnol0The hardware part is complete! The black power supply is used for probing whether the power from mains has fallen, the white power supply is for providing constant power to the pico, the large board is the target machine (my server’s front I/O board) and the white breadboard is a voltage regulator!
@carrot0My 17$ decommissioned FPGA miner arrived today!! After some cleaning and solder work, it came alive and booted into Linux :ultrafastparrot:
@matt0Soldering on some pins to my raspberry pie zero w. (please ignore the shitty solder job, I am very new lol)
@carrot0I finally fixed my homebrew CPU's memory access "bug." It wasn't a bug at all. Here's a short demo of 4 programs running on it via the UART bootloader! Also, I wanted to experiment with showing both the hardware and software at the same time (decided to use Zoom for that).
@ferferite0A phone I am working on, the hardware is mostly done, waiting for the camera module to arrive. It's using an orange pi 3G board, running Android. It's the second time I am making the case for the phone, but this time I am adding a camera to it and making the case nicer in general(thinner, using brackets to hold in the parts instead of glue and using as many screws as possible).
@manasmw3330Yesterday was the Day 1 of our 3-Day Arduino bootcamp. We have organized this bootcamp to celebrate Arduino day and we had around 75 participants yesterday.:yay:
@obreymuchenajr0Yesterday we celebrated arduino day with Transfer multi-sort Electroniks (TME) I and @edwardphirijr698 presented our robot and won the TME arduino board and tshirts :)
@prithul02180Won the best hardware hack at DVHacks, thanks to the Orpheus Leap :ultrafastparrot:
@obreymuchenajr0yesterday's electronics workshop was Amazing!! There was me giving an introduction to arduino :)
@manasmw3330My agenda for Arduino day has been approved:ultrafastparrot:
Our council will be organizing Arduino workshop and live demo for Arduino day:yay:
@sampoder1today i presented.. the *CLIMATATOR*! it’s a 4D interactive media experience / climate change simulator that showcases the effects of climate change to a younger audience. you enter the cabinet, put an AR headset on, watch a fictional weather report from 2050, then you begin to feel the heat of a heatwave 🔥 (there’s a strong heater inside), then you going on a bumpy ride (haptic motors) in a fire truck fighting wildfires :firefighter: (it’s still boiling from the heater and it intentionally smells of burning) and to end of your experience a cyclone with winds (a big fan) and shaking (haptic motors) 🌀 + it’s got sound effects and a nice video (this is my myp personal project, goal was to create an engaging way of learning about climate change)
the wooden structure was put together with a lot of drilling and with the use of recycled materials to the extent possible. i learnt a lot about woodworking as this was my first ever real woodworking project.
*this is biggest project ever, it’s taken me since August to build this all out…..* and i’m really proud of the final product. uses a mix of Raspberry Pi Python, Arduino, Next.js & Node.js to all work. the AR headset is powered by Holocron (www.npmjs.com/package/@sampoder/holocron)

@ella3First time building a circuit with an arduino! Took me a while to get it to work :flushded:
@taylorleehackclub0I spent most of my weekend practicing algorithmic problems, and I got an electronic kit from CodeDay. :codeday: I don’t have much experience with Arduino, so I am excited to see what I can build!
