3x3x3 LED Cube


[portreathbeach] built this simple 3x3x3 LED matrix. It uses a PIC16F690 in a ZIF socket for the brains. Each layer has nine LEDs with the cathodes tied together. The anodes from each LED are connected to the LED below. The LEDs are multiplexed so that even though all layers appear to be on, they’re being addressed individually. He’s included software, so you can build your own animations. Video of the matrix in motion is after the break.

  1. seriously, what’s with the led-matrix obsession? the damn things are almost useless. unless you own a bar and need a scrolling marquee sign to advertise happy hour. but that’s so last season, just like neon.

    the first thing i did with a microcontroller was build an 8×8 rgb led matrix. i have no idea why. and now i’m going to have to build one of these. damn you.
