Introduction: 3x3x3 Led Cube NO ARDUNIO
Please vote in glow contest :)This is a very simple led cube that does not need an ARDUNIO to program. It blinks 512 different patterns before restarting.

Step 1: The Base and Frame
To make the base you need to cut a peace of wood and drill holes the same size as your vertical wires. All the wires running vertical are ground
Step 2: Solder the Cube
Soldering the cube is pretty simple once you have the frame done. Just solder the negative line of the LED two the frame and the positives of 3 of the LEDs together so they can connect to the 4020 outputs.
Step 3: The Circuit
This is a relatively simple schematic to do. First I would recommend putting it on a proto-board and marking sure it works right then you can permanently solder it together. The circuit uses 12 volts dc. The nine pine out of the 4020 go to the 9 positive cube out puts. The circuit is very sensitive to the wrong voltage so be careful
We have a be nice policy.
