Step 1 - Test the LEDs

You will need 512 properly working LEDs in the lattice. They will need to be stable and bright. This step will show you how to separate

the faulty ones from the usable ones.

Lots of times there are broken LEDs, especially when they come in large packages. The damage may be noticeable but sometimes it

is not. Start by bending the shorter leg (the cathode) at a 90 degree angle. Hook it up to a power supply and run 3V across it. You can

do this with 2 AA batteries in series, but I had a power supply with alligator clips. Either way, just make sure the LEDs are working

before you begin to solder.

Step 2 - Build the Rig

Create an 8x8x8 template so you can create the layers. You will need a peg board and you will need to drill holes into the peg board

to space the LEDs 1/2" apart. I put foil over my rig to hold the LEDs in place so that they wouldn't move while I solder, otherwise they

would jiggle to much. Use the LEDs to punch holes into the foil.

Step 3 - Starting the Layer

The picture should show you how to do it, but basically have all of the LEDs in the row facing the same way. Begin with the corner

first. The corner row should be 90 degrees facing the other way. You should also align each LED so it is just barely touching the next
