This simple neon alternating flashing circuit was found in an old American publication. The current is very low, but the supply must be made with at least 100 V.
Capacitor C and resistor R in this circuit determine the time the output remains at the high level...
This configuration was found in an English magazine from 1965. It is valid for any junction FET. The...
This circuit was obtained in a Motorola documentation from 1966. The circuit can use a common FET...
