I understand completely the DIY thing.I'm going to cater for the home DIY toner transfer crowd and try to put the UNO upside down on the top if I can - soldering will be easier -.
As for the inverted UNO, you might consider adding a reset button since the Uno's will be obscured, or remove the board underneath it so one can press it. Being inverted, it should be at the lower left corner, no? I guess that would depend on the final orientation.
Regarding the board I posted, I checked dirty pcbs and they have a blanket cost for 10 boards, 10 x 10 cm, for $25-28 USD, so that's less than $3 per board.
Pot's compatible with the ones I used are $5.59 USD shipped within the US for 16 on eBay, so about $0.35 each. The biggest differences are these have a shorter shaft, and have a center detent. There's a listing for 1,800 of these for $70 USD too.
I'm not sure about the screw terminals yet, but probably a less than few dollars each ignoring shipping.
LED's, resistors, switch and pin headers should be less than $10 USD all together if sourced from eBay or similar.
If someone made a batch of boards, it looks to be about $30 USD for everything less shipping and the Arduino.
If there's sufficient interest, I might have a go at this.
Or if anyone has suggestions for changes let me know too.
