I built a ridiculous 1000 pixel display that takes an hour to draw an image and I'm now asking the internet to draw on it (what could go wrong?) Please submit some 40×25 pixel art at kilopx.com!

Love this, and I've loved following this 🫶 I was only 34% confused when all I knew was that you were cutting up cubes of wood & painting them 😅 Hoping to make a 40x25 BOOST logo - it's been great to see what people have submitted 🙌

This project has everything: a web app, a physical controller, a custom CNC build, generated gcode, tons of fabrication, 3d modeling, 3d printing, material sourcing - so much to get lost in. It's the most ambitious project I've ever built.

Picking pixels was a real adventure. I've tried ping pong balls, styrofoam balls, bouncy balls, wooden balls, 3d printed balls, golf balls, foam balls... The problems I encountered were largely cost (even a 50¢ ball is $500 of balls), weight (again, 1000 of these things), and availability.

I built a whole CNC machine around the wooden cubes, and I can tell the machine to go to change a specific pixel. Just one at a time, of course.

Fantastic use of technical skills, patience and creativity. I've always been a proponent of repurposing and was wondering if you think the use of parts from other products like copiers etc could be repurposed into projects like this effectively?
