6x6x6 LED Cube

thingiverse

This 6x6x6 LED cube consists of a total of 216 individually addressable LEDs, each adjustable to 8 brightness levels. It utilizes an Arduino Uno board for control, with power supplied via a 3A 5.4V source through a USB cable soldered to the board. The project's Eagle schematic and board layout can be found in the led_cube.zip file. The base was printed on a Makerbot Replicator using .3mm layer height and 100% infill. For the open Scad file of the box, ensure the path for the MCAD\boxes.scad file is correct to avoid crashes. Arduino libraries for controlling the cube are included in the libraries.zip file, while a demo program can be found within LED Cube Demo1.zip. The cube's construction involves connecting the + leads of each layer and column, while the - leads are connected together and to the 36 ZX drives from the LED driver chips. To power the Arduino, make a cut on the designated location as shown in the image, then connect the red and black wires from a USB cable (5 inches long) to the +5V and GND pads respectively after removing the plug-in end.
