Base for Main Board

If you have access to a 3D printer, here is a .stl file for the base seen in the pictures of my 8x8x8 cube

Schematics

Basic schematic of the cube and support circuitry

See port chart for pin assignment detail

Port Table

This file show detains on Mega pin assignments. It also shows detail of the memory array where LED status is stored. Together they make refresh of the cube easy with direct transfer of bytes in the array to output ports of the Mega.

This zip file contains four sketches:
1) diagnostic panel test for use during cube construction
2) The Show - about 4 minutes of different animations to show off the cube
3) Another Show - this is another 9 minutes of animations that are not on the video
4) The Super Show - Everything on both of the above files - a 13 minute show with 35 animations
No preview (download only).
