In prototyping quantity the board itself will run itself well beyond the cost of a Poker on BatchPCB or Express PCB. I don't have the space for a home photoetching setup, the frustration there would be getting the holes drilled anyway (let alone trying to align both layers perfectly).

if you can find other people that want this, check out http://dorkbotpdx.org/wiki/pcb_order - no set-up fee and free shipping. you get 3 copies of your design for $5 per in^2 ($80 per board) but if you can find 10 people, the "medium-run" would be $48 per board.

Whoah, thanks. someone should make a drop in replacement for the boards in the Poker DIY thread.

I'd be in for a pcb groupbuy if it had the same fit as the pokers pcb but was programmable.

I was thinking about a poker sized/spaced PCB with a 44pin TQFP footprint for the hip new Atmega chips that have USB functionality built in, set between DIP headers that fit a Teensy if people want to go that route. The extra pins from either controller are broken out into a through-hole protoboard style area to mess around with LEDs or battery/bluetooth contraptions.
The idea is that the board could accommodate the broadest set of ambitions while leaving the trodden path clear: Usable with existing aluminum cases, Teensy mods, etc.
Loligagger:
Sounds ambitious, if you can pull it off though I'll totally be in for one.
