Flashing Neons (NE-2 / NE-51)In this circuit, one, two or three neon indicator bulbs can be made to flash
in sequence at rates determined by the R and C values. In the single stage
circuit, using one lamp, the capacitor charges through the resistor until the
ionization potential of the neon is reached (about 70 volts) and then discharges
quickly through the lamp until the voltage falls below what is needed to sustain
the lamp which is approximately 45 volts. The cycle then repeats at a rate of
about 3 Hz for values shown. Smaller R or C values increase frequency, larger
values decrease frequency. All capacitors should be the non-polarized variety
with a 100 volt or more rating. For more than 3 stages, the lamps may need to be
matched for similar turn-on voltages.
