that being said try a nail a screw lol how about air 

if you are lazy.........   lol


buy a relay ... 

i can teach you yet 1 more trick

lol

try to recover it in a  BIG CAP..... even bigger than it could posibly drain in 1 pulse.....

now tell me you dont get the mechinical work for free

never mind the extra electrical engery ... 

and well your at it tell me i didnt crack it 


ist! 

BTW  i dont got the CRACK POT AVITAR 4 nuttin 

@IST

I am interested. Can you elaborate more on the relay and big cap suggestion? I am going by Radio Shack later and might pick up a relay and big cap if you suggest what to get.

@ Goat
I apologise for my 3 post later on reply, I go to sleep for 7 hours, when I wake up there are 3 more pages added to the forum, and more new people coming outa-de-wood-work, ha ha.

On your LED warnings.
YES, I totally agree with you, some of these LEDs can be driven to distruction, in the process of doin so, they are able to exceed many times their normal "rated" brightness, so all those reading this, PLEASE TAKE CARE when you are experimenting.

                                                              DON't look directly into the top of the LED

Procedure
make sure you have a suitable resistor in series with the LED (not like me, feeding DC and HFz directly to the LED) I should know better.

If possible, put a "T-Pot" or adj resistor in series with the LED.

I just didn't think about it, and could have payed with it with some eye loss, I was lucky.

Goat, thankyou for posting the original warning, and this last one as well.  TA muchly.

Torroidal cores and ferrite cores can respond to highfrequency changes in voltage whereas laminated soft iron is for much slower transients.  Torroidal cores can also utilize eddy currents wheras laminated cores are insulated so as to discourage eddy currents.

@sparks...

why high freq?   you wont want it trust me!!!

the big diff with high freq and low freq with the right coils IS.....HOW MUCH DO YOU WANT!!!..... AND STAY FAR AWAY FROM HARMONICS AND RESOSANCE!

or tune your coils to crap and and hit it fast as the cam flash does... the jt ....  a poor way to go 

@timmy          any relay and a big cap best to play and find out or if you know electronics....  then match it ..   i cant say for sure ...

i have been playing with a big one 120 000uf 15v and i can hand pulse it way past its rateing .... HAND PULSE...... IN SECONDS....mabe 20seconds 

ist!

i forgot to mention im useing a MOT.... but it is no diffrent with a relay matched 

of course there is more parts involved....  and i aint talking ... 


BUILT IT.... IT WILL TEACH YOU

@IST
I don't want a cap THAT big 
My photo cap is as big as I will handle with my limited knowledge.

like is said guys i can go on for ever bout this stuff... 

and im not trying to pump my ego by anymeans im trying to get you in the right dirrection as nobody wants to figure out the puzzel as i have done ....

call it a boost if you like 

i cant watch people waste TIME....

no body read tell the truth thred eh?.... 

been a year already....

you guys are smart youll get it faster than i ever did .....  lol but i also had to reverse engineer the dam TPU  like 50 times first .......

its all on this site..... 

and i never picked up a peice of wire b4 i started with the intenction to wind a coil .... 

so if i can do it solve it prove it all .... 

SO CAN YOU 

ISTEAM!!
