This flasher for incandescent lamps was found in Radio Electronics magazine from July 1968. The frequency and duration of the pulses are adjusted in R1 and R3 depending also on C1.
We present a circuit formed by six voltage comparators. Each comparator will analyze the voltage...
This circuit can generate time base signals from 5 to 1500 Hz. We find it in a documentation about old neon...
In this circuit the CA3140, an operational amplifier, is used as a comparator with the zener diode...
