Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...

Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow ...

It's only a circuit breaker. How hard could it be? A surprising number of engineers specify the wrong type of circuit breaker to protect their equipment. Engineers ...

This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...
