The effeciency is about 1% if I remember correctly for 593.5nm. For 589 I think it is around 3%

USAbro, I know someone who made a coil about 2 years ago with a tank cap consisting of salt water and many soda Bottles and powered by a 4 kv 60hz nst. They estimated 1 million volts but the arc length said 700kv. A little over 2 feet arcs! Not too bad for a crude sgtc eh?

What current was going into the ld?

Nice find on the 120w! The corona will get you massive losses. Also high frequency passes through glass which is what your Layden jar's dielectric is made of. Either use an NST for 60hz(lol I know you hate hearing this) or get a professional capacitor made for rf.

Meh it's not too bad. Does require a good bit of messing around with lenses though.

I'm guessing with a cfl you are getting give or take 1 ma from that flyack

He said he is using a 14w ballast so any loss is a big one

You MIGHT be able to get the cfl ballast to work IF you know the frequency. It should state the frequency on the ballast but if not you need an oscilloscope to see it. Good luck and be safe :)

Get an nst. Do V/I=Z. Then do 10^6/Z*frequency*6.2832 That will give you the required tank capacitance in uf An oscilloscope would not be needed.

Not to sound rude but that doesn't tell me anything. All cfls use high frequency and almost all use mains. A flyback uses a ferrite core because it is made for high frequency. You need to know he voltage, current and frequency for the tank cap equation. People use transitors and zvs because...

There should be a rating on your ballast for current. I am still not sure what you are asking but from looking around it seems you want to build a tesla coil. A cfl ballast won't work very well for a coil from what I have heard. If you say it's 14 watts especially. Why don't you just use...

Is that a rating for a resistive ballast? If so that wattage rating has nothing to do with power out. It is just saying how much it wattage it can dissipate before you need to upgrade. As for voltage it is impossible to determine but 1.5 cm is more than 8kv with a rounded surface

That depends on the input. But generally, if it looks dangerous then it probably is. :D A flyback can put out almost as much as it is supplied with. You just need to change out your components. The irfp250s are good but with more power you need to switch to something like the 260s...

He's saying that mots are rated for THOUSANDS of watts. neon sign transformers aren't. Most are less than half that wattage and the big 60ma 15kv ones are pricey and still only get 900w. A mot is not built with safety in mind like nsts. Too much power.

Can you take a picture of the connections on the driver and diode?

New Arrival 50000mW Adjustable Focus Burning Match Lazer 301 Green Laser Pointer Pen with Safe Key for Sale 8000 Meters-in Laser Pointers from Office & School Supplies on Aliexpress.com | Alibaba Group Seems legit to me(sarcasm)

They look interesting. Good luck with the sale!

Interesting. Although it would be very practical , I feel it might bring more legal attention here if people are starting to use them as weapons. We are trying to keep eyes off lasers as weapons so that we don't ban them. In the US we are pretty lucky. But if we misuse the privilege it could...
