This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

This tester is intended to quickly check whether a transistor is functional or not and possibly also select two or more transistors with (approximately) equal gains. This is about the simplest ...

These days, the electronics hobbyist is lucky to have access to a wide range of ready-made modules that enable sensors, screens, and microcontrollers to all be linked up with ease. However, this ...
