Using the 723 integrated circuit, this power supply has the voltage determined by R2 and R3, which can be changed. The circuit is from a Radio Electronics magazine from July 1971.
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...
