MAKE A HIGH VOLTAGE SUPPLY IN 5 MINUTES

Step 3The Finished Setup

The Finished Setup
This is how the finished high voltage supply looks like.

Remember, this is a DC supply. The output from the thick wire is positive. In TVs and CRTs this high voltage output drives the negative electrons from the filament to the screen.

If you need AC high voltage, you have to remove the built-in diode or find an old flyback transformer that does not have a built-in diode.

ok i think i did somethin wrong cuz when i was doin the 9V batery part i dident get a 30V spike and i thought it would only be 30V so i dident take the time to put the covers on my alligator clips well i got a spike over 600V thats as high as my meter reads and umm it hurt alot all the way up both my arms

HAAA THATS NOTHING YOUR AN AMATURE I GOT JOLTED WITH AN ORDER OF 100KV AND LIVED TO TELL THE TAIL.

Sounds like you pulsed that 9v into one of the lower impedance auxiliary coils haha.

someone have an idea how can i made an high voltage supply but with extremly low Amp ? the kind of i can touch without dieing ?

Try making a Tesla Coil

A Van De Graaff generator is a great way to make high voltage at less than a milliamp!

I messed this project up and i created 1000 volts unreadable amps

Try the 2n3055 transistor driver, it is very easy for beginners. I have made an instructable on the 2n3055 driver on my page if you are interested. Here http://www.instructables.com/id/2n3055-flyback-transformer-driver-for-beginners/

I looked at it before this one but I didn't have the 2n3055 transistor but I had the Parts for this one... But yes if I had the parts yours would have been really easy but comparatively this and that are both about the same level of difficulty.

y have complet circuit but not work yet
if i test the flyback with 12 volt whats nomber of volt i will see in avometer

Can this power supply be used for a plasma speaker?
Aug 18, 2010. 6:57 PMJimmy Proton says:
yes
Aug 22, 2010. 6:53 AMBigKahuna666 says:
could you send me more information on how to do that? I would love to make a pair of plasma tweeters
Apr 14, 2011. 7:22 PMaweis says:
so, how would i make this suitable for a Tesla coil from 70v alternating current generator, how many volts output would it achieve, how difficult would it be?

so how do you remove the diode without ruining it

Looks dangerous, that setup. The non-conected two red leads on top of the flyback (some mm from each other) is focus and G2 voltages, and represent respective 7.5Kv and 800-1200v. ( in a 300v pulsing setup, like a crt) These two can deliver bigger currents than the hi-voltage (eht) output. Been rapairing crt´s for 20years, an focus lead is the worst smack a tv can give.....(40 minutes with shaking and swearing and smoking) Be careful all of you, and pulldown the focus with 1k5 (hi voltage rating, 5W) and G2 with 2k2 (hi voltage rating, 2W min.) and isolate those. If the CFL is pulsing you will be hit by the hv-ghost........ (been there, done that......)

SO thats what it was. HV-ghost. felt very shocking.im never playin around with fly back transformers anymore. Dont want the FCC bangin down my door.

And freaking awesome too! All  great achievements were once thought dangerous and impossible. Just be careful folks.
