Inside Minimatrix

In this video Nick Johnson demonstrates his tiny Minimatrix project and wrote a detailed explanation describing the build: While minimatrix is in principle a pretty simple device, there’s a surprising amount of detail that goes into getting it right – and some interesting lessons to be learned in designing and programming it. I thought I’d […]

Minimatrix: A small and simple self-powered LED matrix

Nickjohnson posted his minimatrix project in the forum. It’s AVR powered 8×8 LED matrix, with an IR sensor for communication. It has just 8 parts in its BoM: A one-color 3cm LED matrix, an ATTiny2313/4313 to power and drive it, an 8-way resistor network, a battery holder, and two decoupling capacitors. Finally, it has a […]
