8x8x8 3D LED effects with Borg 3D

This is what I call some time consuming project. 8x8x8 is 512 total LEDs to solder. But end result looks really cool.  Each LED in this cube can be controlled individually by ATmega32 microcontroller. The controller board can be interfaced to RS232, CAN and two joysticks from the C64. To control such amount of LEDs isn’t easy task without special time controlled multiplexing. The cube is divided in to 64 LED planes where each plane is switched about 100 times per second, so for spectator it looks like individual LEDs are controlled separately. Construction schematics aren’t final, but you can see some versions here. The complete software is written in C for the AVR-GCC compiler and can be found here. Continue reading
