Thanks. For the prototype I would probably just use an Arduino or something similar. But I am thinking it may go the PCB route eventually if the idea goes beyond that. I want the device to be fairly small. And no have not heard about those. I will keep those bookmarked!

I would like that. I am always trying to meet people to work on things with. Shoot me an email [email protected]. I am just about to graduate university so am looking for things to do (and to get out of the city).
