Well hello everyone. Today we’re going to talk about cigar box guitars (CBGs). For a while now, I’ve been noticing more and more references to CBGs creeping into popular websites, including one of my favourites, boing-boing.net.

It contains a  battery charger and a battery health indicator and  a few other components.  As shown in the circuit, ...
