I have soldered a negative ion generator. And it has a neon lamp (GT-NE6S1325T) as a discharge speed indicator at the output side. The setup looks like this:
The idea is when the capacitor accumulates enough charge (90+ V) it goes through neon bulb. The neon lamp does blink as the electrodes on the left discharge negative charge into air. It blinks faster in damp weather or when I bring hand closer to electrodes.
With current setup the interval between blinks is too high ~8-10 seconds or it gives very dim constant light (no blinks) when I bring hand closer.
How can I increase the blink speed to make it more noticeable. And I want to make sure it blinks (i.e. no constant dim glow when discharge is faster).
- Should I decrease the capacitance. What value would be ideal? 10 nF?
- Or, should I decrease capacitor rated voltage from 630 to 400 or 240 V?
- Or, should I decrease 1 MΩ safety resistor's value?
- Or, what other change or new components are required in the circuit?
Also, if I want to reduce the blink rate in rainy seasons. How can I make blinks adjustable without hampering the device performance much? A potentiometer in series with the capacitor?
