The tester worked surprisingly well – it was able to correctly identify BJTs, FETs, even esoteric parts. The only thing it balked on was a linear voltage regulator, which showed up as two diodes.
The tester itself is relatively simple to build. As you can see in the video below, it consists of a power supply, an LED, a few resistors, a pair of known transistors, and not much else.

This automatic battery-charger, built around a single transistor, starts charging when the battery voltage drops beyond a preset value and stops when once an upper preset voltage is reached.
Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.
