[LUG] Battery powered Pi

 


Really for TomB, but for anyone needing 5v off batterys, then use an SMPS regulator rather than a bog-standard 7805... I've used these:

but there are many others. Just search ebay if that's your thing. Also looking on the mobel radio-control/robotics sites for something called a BEC or UBEC - does the same thing - provides 5v from batterys via a swsitching regulator, so low-loss (ie. doesn't get hot enough to burn fingers!)
