I'd like to upgrade my buttonhack to the 4-LED system. Right at the moment, hulkster.net isn't responding (dunno why) so I can't go check the web site to see if Brian offers the 4-LED version of the board as a separate sale or not. Even so, I get the impression he's behind in shipments, so I'd be curious to know if I have any alternatives to getting a 4-LED board made. For instance, aren't there online sites that will produce a PCB from uploaded plans?

Also: I've got his original 3-LED system, does the 4-LED system require different electronic parts, or can I just use the parts from the 3-LED system and merely add another LED?

Or maybe there's someone who already has a 4-LED board and the necessary parts in stock, and I can just buy it from them?
