fec provides forward error correction for SDR, space, and satellite applications. fec implements two error-correcting codes that show up throughout software-defined radio and spacecraft links: Convolutional codes with a Viterbi decoder (hard and soft decision), including the common rate-1/2 k=7, rate-1/2 k=9, rate-1/3 k=9, and rate-1/6 k=15 codes. Supports any rate from 1/2 to 1/8 and any […]

Build a fun and playful 3D printed MP3 player with CircuitPython and an RP2040 PropMaker Feather! It’s a boombox for young makers, but with a twist: use a color sensor to detect a LEGO DUPLO brick and play a song, sound effect, or audio clip. Each colored brick plays a different audio file. You can […]

SoundEngine plays short WAV sound effects on an ESP32 through an I2S DAC. Clips live in flash as byte arrays. The engine mixes any number of them together and streams the result to the I2S peripheral from its own background task, so play() returns immediately and playback never blocks the sketch. Each clip carries its own volume […]

If you want to know what makes them special, you can head to their website or check out this 2yo r/pencil post (but be careful, you […]

Daniel Mangum has recently been working on a mechatronics project that involves constructing an X-Y cartesian motion system. I opted to use stepper motors to drive each axis, and timing belts and pulleys for translating the rotational torque of the steppers into linear motion. The timing belts need to be anchored to the component that […]

It provides an easy to use […]

Matt Horn wakes up to one original print, every morning. A thermal receipt printer in my kitchen wakes up each day and prints a piece of character art that has never existed before, designed minutes earlier by Claude, themed to the day: the weather outside, the season, whatever the news feels like. A short verse […]

Two years ago, Dominic Szablewski was Porting his JavaScript Game Engine to C for No Reason. He have since found a reason: making a new N64 game. The result is Xibalba 64 – a Wolfenstein 3D-like FPS. Modretro agreed to publish the game as a physical launch title for their M64 (a modern N64 clone), […]

ProvenMetal claim is they makes printed circuit boards (PCB) fast. Speed is our middle name. You ship hardware on a clock. 4 weeks ain’t cuttin it. We do it better. Boards back in as few as five days, or slower and cheaper when the schedule allows. You pick. Fast, and we can prove it. We […]

Damien George, MicroPython’s creator, writes on the MicroPython discussion on GitHub: Coldcard is a Bitcoin hardware wallet, and it’s firmware is built using MicroPython. (Trezor is another hardware wallet also using MicroPython, but it’s not relevant here and not discussed further.) Recently a vulnerability in the Coldcard firmware was exploited to steal over $100M worth […]
