Before you know it you have a truck load of multimeters lying around. They're just indispensable but they're also very cool gadgets. And it doesn't help that AliExpress sells very decent ones for cheap.

My main multimeter at the moment because it basically measures about anything. And it set me back a whopping €11 on AliExpress.

Bought this one for €4 at the Action. Did some circuit bending and added an external measurement board because the ones on multimeters to measure transistors simply suck.
