Based on an integrated circuit of the time, this circuit appeared in the October 1979 issue of Radio Electronics magazine. The circuit monitors voltages in the range of 10.5 to 16.0 V.
The presence of a low resistance between the terminals of the sensor causes this modulated...
The frequency of this oscillator depends on R and C (see math section for electronics). The...
This circuit was found in a 1980s documentation from the manufacturer of the integrated. The...
