Two sensors are used in this simple remote-control circuit, one to switch on and one to switch off the relay. The circuit is from 1986 documentation. The transformer has 12 V of secondary.
We found this oscillator in a 1978 amateur radio documentation. The circuit supports other...
Small time intervals up o some minutes can be achieved with this circuit. Only incandescent lamps...
In the figure we show yet another CMOS component based voltage controlled oscillator circuit. The...
