Nice graph , i have a question for you , at some point you say its useless to put more turns on the pickup, once you have reached that point could you try bigger gauge wire on the jt side to see if it gives you the same voltage.

I hope this make sense , really nice work there , as usual , Thank you !

I am not sure what would help. I expected voltage to increase until core saturated. I do not think core is saturating since I can get over 1000 volts out by decreasing base resistor value.

@xee

To reduce efficiency losses , anyway i think this can change some thing , and i saw a perfect opportunity to clear this up , since you are the best at this .

Sorry if you see it as point less , but i was thinking of current also.

Thanks

I am not saying anything is pointless. I have tried several things, including changing wire diameters. But if more turns do not help, then it does seem pointless to spend time and money putting them on the core. I am just trying to find out if that is the case or not. My limited data seems to show that there is a limit to how many pickup turns can be added to increase output voltage.

@ crowclaw

I assume that a JT is built in. Nice job. Did you say it was powered by your new wireless power invention and sell stock in your company? I bet they would have believed you.

You know, it would make a great claim: ..it's not a perpetual motion machine, it's being powered wireless by the core of the earth.

Some of you tried winding around a magnet? ..I thought I read about this many thousands of posts ago.

i knew my sun would speek ... 

he was winding them yesterday ... ; )    never ran them as it was a test i was conductiong ...

lol   anyhow works as i thought lol 


ok  not the point for my post ..  im makeing for the kids a simple jt lite ...  and for the older kids ... ill add a recover /recharge winding ... im useing the ist mini toroide ..  found inside the ramma sun beam clf's

ill add pics ..   it is a 2 turn jt ... liteing 4 ultra brights ...  ill add secondary recharge coil for the older kids

ist!

on this mini im useing a 33 ohm 1w to stop from cooking my npn's leds are bright  transistor is safe from over heating ..
