If you ask me which instruments I regularly use in the lab, you will hear Multimeter, Oscilloscope, Transistor or Component Tester. And since quite some time I ask myself: How is it possible to build such a versatile component tester for less than 10 dollars. After looking at the minimal parts count of such a device, I am convinced: The inventor was a Genius. Let's have a closer look.
