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 […]

ChipTycoon is a working chip factory laid out as a theme park, created by Laurentiu Raducu. A cart carries one silicon wafer along the roads and stops at each of the twenty buildings that turn ordinary sand into a computer chip. The cargo on the cart is the wafer itself, and it visibly changes at […]

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 […]

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.

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 […]

Birduino is Hannah Robertson’s card-triggered audio player for [learning] the birds. It consists of a deck of bird cards, an audio player, and a card reader. Tapping a card triggers playback of one of the vocalizations associated with that bird. You can trigger a bird-of-choice to learn its calls, or pick a random card and […]

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 […]
