This simple circuit is intended to test the zener test. RV1 can be calibrated in terms of voltage. The maximum voltage of the tested zener is that used in the circuit supply.
This indicator makes use of an LM339 voltage comparator circuit that contains 4 internal...
This 3-channel sequential circuit, but which can be expanded further, uses triacs to drive...
This soft starter dimmer was found in a 1980s documentation. We can implement it with current...
