This isn't metalizing I know, but I did it today...
Mini Neon Driver From Disposable Camera Flash
This is a high voltage DC circuit made from an old disposable camera flash. Its similar to the popular Joule thief I believe. Here is the diagram:
This is exactly as it is in the flash except I've removed the rest of the circuit, like the high voltage capacitor. Ouch! Also the switch in the doodle is closed permanently.
In its place I put a mini neon bulb. I like freeform circuits.
Below its running at 1.5v. I don't know whats the voltage across the neon. (over 100v but less than 400v)
Here's the power supply. Its reading .5 amps at 1.5v it goes up quickly when the voltage rises any more. As this is a DC circuit only one side of the neon glows.Would it be possible to do AC by using two of the above circuits at 1.5-o-1.5v?
The neon in the power switch is more impressive...
