i have noticed the mps transistors work alot better than 2n transistors
i have watched a mps2222a work at 0.2 volts.. my first earth battery

  Hello everone...

   I'm finding it fairly hard to find a nice large toroid here in Australia, so I have done the next best thing...
   I am using my trusty little  1.4"(35mm) ferrite toroid, I am currently using 2x of these toroids in a JT
   with 1x (used) AA battery, so far achieved 925 volts with only 140 turn secondary,
   my 2x toroids are not connected in series
   and I'm very happy with those results, but  I am going to try to get a bit more volts,
   I am lighting an  8 Watt 220-240v AC CFL twist, quite nicely,
   with 2x (used) AA batterys it lights even brighter at 1248 volts, I will soon post some pictures
   of my light...

I was able to light a fluorescent tube wirelessly using slayer007 circuit. But tube ends need to be less than an inch from the metal plates.

Fantastic xee did you wind the coils in opposite directions?  Also at 6v what is the circuit drawing for ma?

I am not sure which way coils go. Just reverse one set of leads if it does not work. I have not measured current but it is high. I gave up using phone charger because the batteries would only last less than 1/2 hour.

EDIT: Cell phone charger will light tube wirelessly if battery is not too dead. So current is probably about 200 mA.
