I have always wanted to build an LED cube. They have always intrigued me. I found plans for a 3x3 in the dummies book and after reading it, decided to expand it to 4x4 (I only have 100 LEDs).
I went online and printed a grid of 1" squares and taped this to a styrofoam lid. I poked the centers and removed the template then finished the holes by inserting an LED into each one to expand them. I followed the instructions for the 3x3 but continued with a extra row and column, connecting the cathodes together. I made 4 layers. The last LED in each layer did not get its cathode bent as this lead will connect to the cathode of the LED in the layer above it.
I currently am in the process of calming my nerves so I can solder the anodes together on each layer. I am going to try the method given in the book which says to make a small bend in the lead and solder it together.
Here are photos of the build so far:
