A useful gimmick?


Since a lot of stuff depends on 3v logic/power nowadays, I rigged this up.

It’s a CR2032 button-cell holder soldered to a couple of flat-toothed alligator clips.

I found these at a local component shop.  The flat “lips” of these clips make them perfect for clamping onto edge-pads like a micro:bit or one of Adafruit’s little dev boards.

They’ve also been useful a few times with Charlie and other Pi related things.
