@Gadgetmail,
soundscope...  thanks. I will see if there is something like that written for linux. looks good

thanks

any how i can continually short the cap it is always full.... 

but i cant seam to get it to fire on its own....   hummmm


ist!

IST,

I am not sure what you mean. (but this time close enough to engage it, so thanks for the clarity!)

When you say 'continually short the cap' are you doing that by hand?

To fire on its own? into another cap? into the inductor? 

What you are doing is very interesting. I will appreciate being able to follow along with you.

Thank you,

jeanna

well i built my power supply

i used a d cell battery a cam unit ...  modded  and a 275vac 1uf cap a rectangular yellow one found inside a microwave ..  looked on the net for info found none .....   go figure ...

any how i can continually short the cap it is always full.... 

but i cant seam to get it to fire on its own....   hummmm

any ideas....

i will post a pic soon of the unit i made ...  i will if i must use relays to switch it but i would like to have it fire on its own  i will then dump this cap to a coil of low self inductance .. and see what comes back or use it to produce magnetic waves in an induction style generator that spinns 

ist!

@ innovation_station

Not sure if this will help but maybe take a look at Gadgetmall's circuit where he uses an SCR and a high voltage diode to dump the voltage out of the caps as seen here http://www.overunity.com/index.php?topic=6519.msg149358#msg149358

yes i just shorted it by hand DO NOT TOUCH IT!!!

it might hurt...  lol

here is a pic i want to get rid of switching to drain the caps .....

there must be a simple way

@ IST:

Can you maybe place contacts, or a single contact, on your spinning disk to discharge the caps?  A simple copper spring type contact (as used on mini slot cars here in the US) might work.  Then, the faster your disk turns, the more shorts you get per second.  Just a thought which may not be useful.

that ring is for the young effect i called it the young ring 

any how i grabbed one of thease power boards from a microwave it has a toroide wound on it with heavy windings so i hooked it up to my cam flash unit and powered it from the 1uf cap hooked my meter to the out put of it .....

now i have 622 vac and 287vdc and i hooked my meter across both on my miliamp scale and it reads 7.25 miliamps

now im not so good at metering things but that seams powerful....

ist


pic of new unit soon


and meter readings
