The post details a few simple neon flasher circuits, which can create beautiful flashing light effect using ordinary neon bulbs.
The ionization potential of a neon utilized in the circuit is around 70V. To the acute left of circuit 1, a neon is connected.
Simple Neon Flasher working
A 0.47 microfarad capacitor connected across the neon gets charged through a 1 MOhms resistor.
The moment the voltage across the capacitor reaches 70V, the neon gets ignited because the capacitor starts discharging through it.
The capacitor is discharged through the lamp, creating a flash till the voltage falls below 45V, a sustainable voltage for the neon to glow.
It is a neighborhood of the circuit. Smaller values of R and C will end in a rise within the frequency and the other way around.
The other two circuits are for the second and third neons respectively. All the circuits operate an equivalent principle.
