Low-Cost and Low Frequency Oscillator-Flasher

It is a low-cost circuit diagram project for Low Frequency Oscillator-Flasher Circuit. Electrolytic capacitors are unnecessary to generate a 1 cps frequency. As an scs triggers on, the 0.2 µ¥ commutating capacitor turns off the other one and charges its gate capacitor to a negative potential.

The gate capacitor charges towards 24 volts through 20 retriggering its scs. Battery power is delivered to the load with 88% efficiency.  The 20 resistors can be varied to change prf or duty factor.
