Simple/powerful Flyback Driver from a Computer SMPS

Picture of Simple/powerful Flyback Driver from a Computer SMPS
I found a way to use a switch mode powersuply from an old computer i had laying araund as a spair. It is very easy to build and gives you 1-4 cm arcs with an input of abaut 4A.

Step 2: Step 1:


Open The powersuply.

Just disconet the suply from mains power, disconet from computer.

Step 4: Step 3:

(do not use)
Hook up a bufer capaciter betwean the two wires from the transformer.

i used a 22nF 250VAC capaciter
do not use a Elko!!! they will explode

the capaciter triks the powersuply into thinking that ther was a user hooked up to it and prevents a high voltag feedback from the flyback into the powersuply.

use an induktor from another smps and hook the capacitor mentchnad befor in paralel with the induktors coil. i coil shold give u 4-6A. this methed produces a lot of heat, thats why you sholdent use this more then 2-3 min.

Step 6: The Test

This is a video from me of my driver in use.

good ible but the spelling, not so much. i understand that you have dyslexia but can i suggest you use Google chrome as it has a spell checker just like Microsoft word or get someone to read it over.

It's nice of you to take the time and write this. I'm really not trying to be a jerk, but you should consider learning to spell correctly if you expect someone to take you seriously. Would you trust someone that can barely form a sentence to tell you how to safely build a dangerous device? You seem intelligent, so at least use spell-check...
Anywon who can't think of more then one way to spell a werd has a week mind.
You complain about other peoples spellings but then don't get it right yourself. That's rich.
You really need to leave people alone, As he said before he has Dyslexia, which is a development reading disorder or something of the sort. This may have been a year ago or so, but I can not help but to reply and say how foolish you are to make fun of someone who simply cannot spell correctly.. So what? I have dyslexic friends who can't spell right, but I don't make fun of them. People like you really ruin the fun on Do It Yourself sites and Video Sharing websites such as Youtube.


(btw, learn to spell, emcelhannon. *wink*)

I appreciate your ible. I followed it throughly, However, I almost killed myself due to me not shorting the cap that was sitting in the monitor calling my name. (No, seriously, it gave me 'the look')
