LED Cube (4x4x4)
I've been looking around the web and I found these nifty cubes of LEDs. There weren't really clear instructions on to build one, but I feel like i can figure it out. So this will be the process of building one. I just got 64 White LED to go into my cube. It will be powered by an Arduino.
I drilled holes in an empty DVD case for a template. Why a DVD case instead of wood? Well because when the LEDs get a little to snug in the holes, I can open the case and pop them out from under! :D
So I finished this layer of LEDs today. 3 more to go!
Here are the connection I have made. Every anode in each row is connected together (RED). Each row will get it's own 470 ohm resistor and then tied together into one output. The blue are just wires the have no connection. They're just there to make the cube look more griddy. Decoration i guess.
I just finished the second layer on the cube, and in this picture I'm testing one of the LEDs in my half built cube.
I finished the rest of the cube today and bought 16 470 ohm resistors for each column of LEDs. Then I made a base to but this all on. Its another DVD case :P
DVD Case Base and the trans-resistor board that is still under construction. The arduino will go right next to the trans-resistor board. The trans-resistor board contains the current limiting resistors and the transistors that allow the Arduino to multiplex the LEDs.
Close up of the Trans-Resistor Board. LOOK AT ALL THOSE RESISTORS! :D
