PCB for LED rings

Well… I just finished my own Midibox, now a friend wants one, too :slight_smile:

I would like to teach him, although he has never soldered or programmed before. Will be interesting.

He is looking for a relatively simple Midibox 64E kind of thing, but he wants LED rings.

Is there an existing PCB layout for LED rings which he could use? I searched forum and Wiki but could not find anything.

I think all the LED-Rings I have seen in finished MidiBoxes have been wired down to the PCB.
