Step 2: Solder the LEDs
As i said before, i decided to to this after i built it, so i don't really have any pictures of the building process.
However the pictures below are excally what it should look like. These are from Chr's instructable for his 4x4x4 cube. Also there is additional information on his that may not be included on mine. So go read his too.
First make all four layers, then solder the layers together.
