Xenon flash project
Here's a little puzzle:
I have a xenon flash assembly, probably out of an alarm system. It has the usual big electrolytic to help fire the tube. If it's connected to a suitable DC voltage, it flashes regularly. The tube will fire reliably at anything from about 5V up to 10V, the higher the voltage, the faster the flash rate. What I wonder is if I can work out a way to randomly vary the flash rate so that it flashes at a non-regular rate. The oscillator is a typical transformer plus capacitor thing, there's a neon tube in there which I think will flash over to fire the xenon tube. This isn't anywhere close to an area of my expertise and I'm probably barking (at the wrong tree or mad, take your choice) but any ideas would be interesting.

Re: Xenon flash project
Use a few neon bulbs to make a random flasher. Then use one of their outputs connected to xenon tube for ignition.
