Astable Flip-Flop Circuits
Handy configuration for making flashers or generating squarewaves, uses negative feedback for the bias., NPN darlington transistor, the astable flip-flop without resorting to huge capacitors, Mosfet power transistors will work in most of these circuits, useful for purposes other than flashing lamps,the circuit uses non-symmetrical values,a two-stage AC-coupled amplifier with the output fed back to the input through another capacitor.
