We found this configuration in a 1990 Poptronics. The circuit can be powered by voltages between 6 and 15 V, changing the resistors in series with the LED. The frequency is set at R7.
Incandescent lamps of up to a few amps can be placed to flash with this circuit. The frequency depends...
In the figure we have a circuit that fires from a positive pulse of short duration applied to its...
This full wave control with SCRs uses a different solution to avoid using a diode bridge: a pulse...
