Transistor tester comparison, test and box assembly

Comparing two component tester kits based on ATmega328P and showing how they identify and test various components. For fun, I also assemble the box that comes with one of them. The tester with a color display draws 30mA and the monochrome one draws 13mA in use. Both draw less than 0.1uA in standby.
