LED matrices are so fun to play with. The low resolution and chunky pixels give them the aesthetics I really enjoy.

I’ve built a 64x64 pixel art frame [0]. With the diffuser in front of the matrix, it looks like animations are floating in the air. I got parts for v2, but I’m yet to find time to build it.

I really like how electronics today are very accessible to start playing with. Basic stuff is mostly plug-and-play, and essentially it becomes a software project.

Neat project! I'd be interested in how the power supply is done. I've wanted to do things with LEDs like this, but not knowing much about electronics this always seems the most complicated part to me, specifically powering both the micro-controller and the LEDs with a single wall plug in a safe and reliable way.

Cool project.

I keep wanting to build a large "lite brite" style display for my window. I keep getting stopped even though I have a lot of the tools necessary, like this laser engraver.

You just gave me an idea about an extremely simple way to build this using a Raspberry Pi Zero and my cheap laser engraver.
