Sacrelige!
it was a one milliwatt laser. The same power as a hand held laser pointer.
Iv'e made a 1000 watt laser system. The only thing I haven't actually made was the laser tube for it.

i like it a lot after seeing the video!

I was going to get a neon transformer soon as ignition for a mini as per another thread. This looks like it works really well.

An NST is a bit overkil for a gap for a mini. I would personally use an ignition coil from a car, $30, and attach to an AC circuit. If your interested i could post the ciruit here.

There are two different ways to get an ignition coil to work. One way is through a 12v DC circuit and another is a 120v AC circuit. You're choice.

This circuit is the more complicated one. You may have to order the parts for this. However all the parts are relatively cheap.

This is a basic ignition coil driver circuit for an AC wall power supply. The circuit uses a capacitor partnered with a wall dimmer switch. The best place to find the capacitor recommended for free is in an old TV or microwave and the best place to find the switch is Home Depot.
