Could i use a fly back to power it. Where could i find some easy to follow instructions.

Looks like UV or violet (325nm or 442nm).

442nm...oh man...that would be such an awesome wavelength! And the price is great! Somebody should really buy this (I don't have the funds...) I mean, even for Buy It Now and expensive shipping, for about $325, if this were really indigo/violet, that would be an amazing color to see. And also very original.

Too bad for all these dangers.Those shortwaves flouresce a lot more stuff and they're invisible, could be pretty cool in a pointer, if not for all the dangers and [highlight]cancer[/highlight]. :D

Switch, you and ending with "cancer"............is actually really funny and pretty cool. This alone is one of the best parts of LPF..

Cancer-ray...cancer-ray...cancer-ray...

i got a neon transformer it says out put 3.5kv.It has no plug the input side.How do i tell the polarity..THis will be the first time messing around with the mains :-/

Don't. Please. Just don't.

Messing around with high voltages and short wavelengths with insufficient experience and comprehension of either is a recipe for disaster, to say nothing of lacking both. I know my way around a HT supply, and I would not suggest playing around with a 3.5kV supply of unknown ratings. It constitutes a credible risk of unintentional cardioversion at best, with possibly lethal results. Adding invisible, unpredictable, high-power, short wavelength pulses (and fiddling with adjustments) to that mix is simply not a good idea for a school project.

If the teachers have any wits about them, or care the least bit about their students or their liability insurance, they will not allow this device on the premises. Don't know how the rating criterion are over there, but around these parts, a nitrogen TEA laser would be considered a class 4 unit with a lethal high voltage power supply.

Never mind. Go ahead. Do it.

Who am I to stand in the way of Darwin?

I'm not planing on bringing a plug and it will be in a glass case with a key switch.

I don't think Darwin will mind.He was still dead last time I checked ;D

Guess he wasn't the fittest, eh?

Neon transformers don't have polarity. They use AC so you can connect the input however you want. Just make sure you ground the transformer case. To use it as a laser power supply you will probably need to use a rectifier to get DC. Then you can use it to charge the HV caps or w/e.

Hello All,

Here's another good page with construction details. It also explains some of the math behind it and describes tuning/electrode spacing quite well.

For anyone looking to build one of these, I recommend a flyback transformer over an NST for safety reasons. I've worked on both. A flyback transformer can zap you 4 sure. But an NST can ruin your whole day, forever.

cheers,

Most of the newer ones operate at safe currents. Yes, it'll really hurt, but you'll be alive to laugh at yourself another day.
