This interesting circuit of the 50s uses a fluorescent lamp to obtain a stroboscope useful for the rotation of motors. The circuit uses a power valve to control the 10W fluorescent lamp.
This circuit was obtained in an old American publication from 1978. It can be assembled with a...
Decade counters, such as the 4017, can be cascaded as sourcing signals with the frequency divided...
This circuit uses a dual-gate MOSFET, a rare component today. We found it in American...
