I'm looking for an 8-channel multiple pattern LED chaser/sequencer. I've searched and found different chasers, but none do exactly what I want. I would like it to have a pattern select button, a second button that reverses the current pattern, and a pot to change speed. I found this project:

8 Channel PWM LED chaser

Unfortunately, it doesn't have a reverse-pattern button or pot to change speed. Can this be modified so it has these buttons?

Canakit sells one that has the functions that I need, but the board is too big. On their website, it says they can modify or customize kits for you, but I wrote to them twice and didn't get a reply.

So, does anybody know where I can find a chaser like this? It needs to be run by batteries. The smaller the board the better.

Thank you.
