@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!
@kevindai020My 17$ decommissioned FPGA miner arrived today!! After some cleaning and solder work, it came alive and booted into Linux :ultrafastparrot:
@matt2Soldering on some pins to my raspberry pie zero w. (please ignore the shitty solder job, I am very new lol)
@kevindai020I 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).
@heyrajan0hi hi hi! dug up my sisters old arduino uno and got it hooked up. I’m about to order a bunch of stuff for it, since I only have a few wires and resistors :(
@philipstudentemail0My math teacher has loaned me 2 Arduinos! If you have any ideas or resources pls let me know I have never used an Arduino.
@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 :)
@subham.karmakar2481Finally, after 2 months of procrastination, I cleaned up the CPU 😁
@manasmw3330My agenda for Arduino day has been approved:ultrafastparrot:
Our council will be organizing Arduino workshop and live demo for Arduino day:yay:
@sampoder0today 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)

@ella0First time building a circuit with an arduino! Took me a while to get it to work :flushded:
@taylorylee0I 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!
