BigBoost

This is the final BigBoost prototype soldered to some Matrix Board, which is then soldered directly to the battery terminals.

I'm yet to get the Low Battery detector working, namely because I don't have the right resistors, but soon I shall.

So far it will charge an LG KU990 Viewty and my G5.5 iPod, but I've not got it to charge my old Samsung D900. However these are funny phones, so I can be patient.
