This is a small project I made in a few days during my Christmas vacation.

It's a 5x5x5 LED cube driven by two STP16CP05 LED drivers and controlled by an XK-1 board.
The LED cube consists of 125 LEDs organized in five layers with 25 LEDs in each layer.

Each of the 25 LEDs in each layer are controlled individually and the layers are time multiplexed.
The software consists of a LED controller and a "command set" used to easily create animations.
My initial plan was to implement PWM controlled LEDs to be able to have different intensity on each LED but I soon realized that my stripboard design could not handle the signal frequency required.
More information and a build log and can be found here.

I have seen many led cube type projects using an FPGA.
Its nice to see an Xmos chip replacing academic example's.
By he way, the board layout is elegant.

I love this! I am a big fan of glowy devices haha! Can I buy one from you? I would have it just sitting on my desk being cool!

This is awesome

Neat project you have there i must say

I fancy one of those, so I'm designing a PCB for it. Here is the schematic:

I haven't checked it yet, so there might be some errors.

I'll create a separate project for it.

This would be awesome with PWM... how about one with RGB LEDs?

This is one of those projects you can expand upon when you need to liven up Xxmas.
Now with an XC3, hmmm...

Can anyone help in guilding me how to get start build my own LED Cube?

Any program that can use to design the LED moving pattern.

Thanjs

Great stuff and your project is really awesome. Really helpful for students like me who is interested in LED products and LED signs. Thumbs up for you.
