Maybe if you push the raspberry pi aspect of the project it could gain traction among users of the Pi and Pi 2.
Certainly if you are able to start making the stick miners I would use a Pi. the B+ and the Pi 2 use less power than the original machine.
I guess that is a stripped down USB hub you have there on the wooden block.
I hardly ever bother looking at any other threads on bitcointalk now

I have a rasp pi b older but not oldest model
I have a rasp pi 2 newest model.
The idea of 3-5 sticks on a hub to a rasp pi. power cost lets say 5 x 3.1 = 15.5 watts the rasp pi + hub total watt amount = 25 watts
5 sticks = 40gh if software allows 5 pools 32gh can mine on slush or btcguld or f2pool the other 8gh can solo mine.
gear is so efficient it comes close to breaking even while giving you a shot at every block via the 1 stick on solo pool.
I love the idea of 100 usd to 125 usd out of pocket that pays itself off while allowing me a shot at each and every block.
or mine all your sticks at a 'real' and actually get to break even in 150 days to 180 days.
