Step 22 - Enclosure Base

Create the base for the cube to make it look pretty. I was able to find a smoky reflective surface at my local Tap Plastics. Begin by

drilling an 8x8 matrix of holes just big enough to fit the legs of the LEDs through. Space the holes out appropriately to your cube. In

addition, add eight holes for the ground connections.

Fitting the cube through these holes was probably the toughest part of the entire project, but it can be done. I recommend to start with

one row and bend the legs as they pass through the base. Fit the rest in sections, as it will be impossible to do it all at once. It would

be like threading 72 needles at once, yikes! Do this carefully without damaging the lattice of the base.

Step 23 - Ribbon Cables

Place the cable and header into a vice and gently press the vice until the header snaps close around the cable. Strip the opposite

ends of the cable, just enough to reveal an inch of exposed wire. Wrap two of the closest wires together and solder the pair to an LED

on the underside of the base. Continue with the rest of the wire until each LED in a row is wired.

You will need nine ribbon cables, counting the ground lines. They will connect to the nine male headers on your board. The

orientation of the header shouldn't matter, but each cable should have its own designated chip in order.
