This powerful pushbutton uses a power MOSFET. We found it in a Popular Electronics magazine from the 90s. The MOSFET must be mounted on a heat sink.
Photodiodes can be used to sense moving objects, such as optical switches and encoders. In the...
Found in American documentation from the 1980s, this circuit for general purpose transistors has good...
This simple circuit is intended to test the zener test. RV1 can be calibrated in terms of voltage. The...
