People have asked if and when it would be possible to buy AAduinos. The answer to both questions is “sort of soonish” as I am about to start a crowd sourcing campaign with the good people over at Crowd Supply. Here’s their pre launch page. There are a number of cool projects running over there, Lime SDR is a personal favourite of mine.
This would shrink the dimensions of the system, from a 3-cell-AA to a 2-cell-AA battery.
It would probably not make it into this campaign but definitely should play with one of those. Thanks!
