Here it is.
I only did 3 of 5 rows, the other 2 are connected up the same.
i do not really understand that. i understand the logic and how it works, but not how you would implement it in the cube. it looks like it would control each colomns cathode, and then somehow have a second transistor to control the cathode a second time, but it would be based on each layer. i just do not know how you would wire that. maybe i am understanding it wrong. sorry for my questions, i am just trying to learn. as previously stated, i am a noob. i have been messing with electronics since i was a baby, but never anything like this. thanks so much for your help!
