Here's some crappy photos of my lastest addition. The first position on the switch is "full power" 4.2, next position is "off", next positon is "pulse voltage", next is off and repeats...the batt body is about 3 1/2 inches, rear mounted switch....no lights anywhere...the case has flat edges so it doesn't roll around on the table..I want to make an atty next..there has to be a better atty design out there somewhere...
