@xee2,
Earlier, I forgot to post the drawing of yours that I changed. Please look up about 8-10 posts?
Thanks

Put an LED across the collector-emitter of the transistor to make sure your JT is oscillating. Is it?

i just check my small jt in the other room looks like i will have to cut it off for the nite..
at 9:26 pm it had 1.420 volts and at 10:55 pm it has 1.431 volts..
so to be safe i'll cut it off for tonight.. or do you think it will over charge in 8 hours??
its charging the run battery.. i don't have a second battery in it charging
and i have no ideal why it is charging.. theres no feed back..
if you think it is safe to run all nite i will do and check volts tomorrow

it is a verry intresting toy .. 

you can BOUNCE THE FLUX AS I HAVE DONE YEARS BACK WITH MY CAP CHARGER .....

this is like a 2 freq unit ...  like a pulse motor with a ringing pulse ..

i also had it doing many things ...  this was quite neat tho ... 

ill add the link as i finish it

I think it is safe to run all night because I do not think you are really adding energy to the battery. Increasing battery voltage does not always mean that the charge in the battery is increasing. Leave a battery that has just been heavily used sit over night and the next morning it will have gained voltage (usually). This is a chemical thing.

i agree with you that i am not putting it back in just thought it was weird..
it been running since i built it at 8:00pm.. so at 9:15pm i thought i am going to check the volts and let it run all nite and then check them regular to see if my meter is lying to me..
so i check again at 9:26 only to see the volts being higher so i wrote the specs down ..
and right now it is still running with 1.434.. at 11:27pm..
weird.. i just didn't want the battery to start leaking all over my table while i sleep
if something was going on
