High voltage from CR Battery pile

High voltage from CR Battery pile

thingiverse

Happiness is a warm Geiger counter. I needed a 60v battery for a 1950's vintage counter and rather than use DC-DC Converters it was easier (and cheaper) to have a stack of 3v CR2016 (or similar) batteries. Add as many as needed (20 in my case) and use the 2x Nut + Screw to firmly press together. Holes in the end for the +/- wires, and recommend using a plate against the battery ends (rather than the screw end).
