Joule Thief

i should mention you want to tune off the dirrect freqs ... or  it will blow ...

assume you get close to core resonance .. and intrupt it ... the resonsant wave flys back .. upon cut ...  this means ... insted of NORMAL JT OPERATION where 1 spike is added per pulse ... 1000's are per pulse ...

be careful! 

i do not reccomend mosfets ..  reason they blow up ...  because of the high voltage ...  they do not like it ...

i have blowen many of them in the past ..  plus you need a controller ..

i find bedinin to work well and with my last coil i dont see why a 2n2222a will not work .. i only need a higher voltage to pump through the collector ... the ring will add to the output by original design ...

ist

so on my last ring showen i did laps on the primary pulse coil .. 8 laps infact ... just funny how it ended up ..  so as i pulse primary drive coil it will race around collector 8 times ..  then the 8 coils will bang  and then colpase goes into the collector .. it gets accelerated 8 times over 5 turns .. and the cycle repetes ..  i would expect vhf from such a design ...

Thanks Gadget for the input! I'll use all of your advice.

Paul:

Great testing idea.  Where were you getting the 1.55 volts from?

It was the battery voltage on the JT circuit, but it was not a battery per say. It was an adjustable voltage from a power supply.

These voltages you guys mention, are you referring to how much voltage the JT will produce *without* a load? Are you referring to DC or the peak pulse voltage.

Today I'm looking forward to seeing how many times the AA 2000 mAh NiMH battery can charge the UC. The AA NiMH is fully charged at 1.412 volts.

Also, another experiment is to see how much energy is in the AA 2000mAh NiMH battery. There should be a lot more energy than just 1.4V * 2000mAh * 1 h * 3600 seconds/h. I'll connect the AA to a load, and use the data logger to see how much energy is in one of these little guys.

paul im glad you came to play with us ... the studys and tests your doing are verry important!  and some one with the proper skills needed to do it .. 

it is not that i do not understand how to mesure things .. as i do .. but  lol im not about to do all of it .. as you all have seen ..

i have put forth quite an effort to bring this public .. because ... it is time ..

donot think because i say mosfets for this style are not my first choise ..  that they are useless..

this is not what i mean ..  i can with ease design a unit to bang with fets..  they ARE BEST SUITED FOR HIGHER AMPS.. AND LOWER VOLTAGE RETURNS ...  imo   

this means use 10 of em .. at say 12vdc 1 amp and bring back 120v xx amp  ..

they work if you stay in the working range ..  i have lit bulbs with them in the past ...  from any coil

: ) 

simple...  it dont matter steel copper core no core ......  the 120v bulb still lit .. where the source could not lite it ..

thank you

ist!

i will add a picture of some ... and this is only some of the coils i have wound .. TO ARRIVE AT MY ANSWERS.. .... 
i have built  several hundred things ... ; )

i have at least 1 more pile like that ...  of jt style units .. small ones .. and i have 4-5 boxes full of large coils i have wound ...

EACH AND EVERY COIL OPERATES THE EXACT SAME ...  TESLAS KICK .. as it were called ..

The test is now on its way to find out how much energy is inside a fully charged 2000mAh AA NiMH battery.

Is this with a Joule thief or just a battery ?
