Joule Thief

I will try a neon but the one I have is an indicator type neon so I won't be able to see if both leads are lit.  I tried a 7W flouro and it wont light up.

If you can not see the electrodes there is no need to do the test. I was just trying to see if you are getting single polarity output or not. My test give large voltage for current in one direction and only small voltage for current in opposite direction. I was trying to see if your coil did the same.

How can we transform our high voltage output from our JT into lowerpower at higher amperage???

Use less turns on pickup coil and you will get lower voltage at higher current.

Yeah that's the direction i have been working in. I posted a pic like 40 pages back of something i was working on. I have 8 secondary's at 2.4 volts each producing around 100mAs each at the same time.

Something odd i have noticed is that if I do not balance the load across the pickup coils correctly then anyone of the pickup coils can pull more amps directly from the battery or so it would seem.

Not sure why that is. I still have not found a way to get more amp draw then the battery is rated for =/ but I have hit over 1000 volts from a 300 turn pickup coil.

Take Care All!

Thank you for the infor.  Now I can experiment more.  I have a question though....Will doing this drain the battery faster?

Also will using thicker guage wire also increase the amperage/current flow? Can you use a combination of different guages and add them together to get the best of both worlds?

Ex: 2 pickups
...Pickup 1 300 turns of 30 guage
...Pickup 2 20 of 16 guage

The conbine bridges!

You are welcome. Thank you for taking the time to post all of your results. They have been most helpful.

Yes if you run 8 pickup coils at a draw of 800 mAs it will drain the battery very quickly. I have not noticed any difference as of yet with a thicker gage wire.

I have not tried adding them together. That sounds like a good test.
