Pamk is a small desk assistant I built in my bedroom: a 3D-printed cube with a 1.69" screen as its face, an INMP441 mic, a MAX98357A amp and a small speaker, all on a custom PCB (KiCad, made by JLCPCB).…

I wanted the radio site I make as a little object on the desk, so I wrote firmware for the Waveshare ESP32-S3-Touch-LCD-1.85 (round 360x360 touch screen, speaker connector, battery header). There's no soldering at all.…

I used the ESP32-WROOM-32 for its balance of processing power, GPIO availability, and accessibility. For graphics, I used the TFT_eSPI library to drive the ILI9488 TFT display over SPI, taking advantage of its optimized drawing functions.…

We've been working on an experimental wireless video transmission system using LoRa modulation, and we wanted to see how far we could push it beyond the usual low-bandwidth sensor data.…

Hey everyone, I wanted to share the first milestone of my DIY smart grow tent project. To give you some context: I started getting into these kinds of hardware/AI projects about 2-3 weeks ago in general, and this specific tent project is only about 1 week…

I've purchased a number of these ESP32-S3 modules from AliExpress. I want to use an external antenna, and have purchased a few, but I can't figure out how to use the u.FL antenna instead of the PCB antenna.…

A small Pocket Poro inspired by the League of Legends game. It contains a few games, you can give him biscuits, he takes naps, and you can shake him to make him dizzy. There are also accessories like little hats.…

I have created another internet radio receiver: MiniRadioZero. In stark contrast to my previous project, RadioESP32, this one takes a strictly minimalist approach.…

Hi everyone! This is JoyDeck 2, a desktop controller I developed, including the firmware, Windows application and 3D-printed enclosure. The idea is to use joystick gestures for everyday PC actions, with an RGB ring providing visual feedback for the…

Trigger Warning! I used AI to do A LOT of the implementation. The genie is out of the bottle, and AI is going to be a tool for developers. Learn to use the tool. Anyway. Story time!…

My ISP kept dropping and I had no proof, so I built something to catch it. I'm not sure the finished thing counts as show and tell, so tell me if I've got the rules wrong. Hardware: Waveshare ESP32-S3 1.28" round touch screen in a CNC metal case.…

Hooked up a N8R8 and ESP-DF with a SD sniffer to tap into my CPAP data found out, almost all machines use 1-bit protocol at around 12mhz tho there are more modern ones that ride on 4-bits.…

Hello ! I made this useless, and therefore necessary, claude usage visual tracker with claw'd wandering around, jumping on gauges and running everywhere when at 90% and I love it.…

I've been working on a DIY camera gimbal that started as a mechanical design project and has evolved into a computer-controlled astronomical tracking system.…

A DIY parallel 2.4 GHz/5.8GHz WiFi capture array built from spare ESP32 boards. Lock one ESP32 per channel, stream every node over USB, merge the streams live into one Wireshark timeline. A single WiFi radio can only sit on one channel at a time.…

An idea that I had when my girlfriend and I were doing long-distance. I wanted some of our thoughtful messages to live in our physical space rather than just on our phones. It’s a little frame that sits in her home.…

Lian Li wireless PC fans use a proprietary 2.4 GHz network: WCH RF_PHY basic mode, 2 Mbps, access address 0x71764129, custom CRC-24 init 0xA0F955.…

I've been out of work for a few months now, but I’m getting a chance to work on new projects, learn new languages and technologies, and keep what I’ve learned and done fresh.…

Hello, This post is about a C library, it is not a board review. But I was not able to post without adding of one of 3 "flairs" (AI Generated/Board Review/I made a thing). As a part of a larger project I made a regexp engine for microcontrollers.…

I ordered one 2000mAh 3.7v 103450 battery from AliExpress from a seller that had 1,000+ sold, and honestly I don't think I'm getting it, but now that I ordered it, I realize maybe I should've bought 3 or 4 to increase my chances of it coming in the…
