This is YACTB (Yet Another Component Tester Box). I was inspired by wavexx who posted one recently. My tester is different than any other I have seen on TV so I had to design my own. I liked the philosophy of wavexx so I adopted some of it.

My own innovation was to make the battery accessible without removing the board. The battery is 'attached' using a neodymium magnet. The rectangular pocket is there to fit my magnet. I was going to use two (thus the length) but decided one was enough.

I love these little testers. Small, fast, reasonably accurate, and cheap! Hey, not up to my Fluke, but hey, my Fluke is three times the volume and no ZIF socket.
