This circuit was found in a Dutch documentation from 1970. The circuit makes use of semiconductors that have current equivalents and is indicated by a 0-5 mA milliammeter.
This circuit was obtained from Radio Electronics from the 90s. The infrared sensor is of an...
In the figure we have a typical relaxation oscillator with a SIDAC as well as waveforms and...
Other series amplifiers such as the MC3301, MC3401 and LM2900 can be used on this circuit. We...
