well..... 

nuts... 

your a nut for free things gadget! lol  lol

and i might add you know how to get em ! lol   

i did the next coil works out to 483 turns per coil on avarage  x 8 coils .. = mass of collector   this is only half the jt tho ... remember .. lol

ist!

if you build this coil wrong ...  it is gonna blow up ... ok ... 

so dont do it wrong ... 

thank you !

for 1 the last thing you want is this ring im building to continue growing ... if this is what happins it will blow up ... do not put feed back into the ring .... via coils ...  use a cap for that .... 

look at it this way ... if i pulse  a coil and allow that engery to combine with the forward engery .. then i take that back to the start ... it will amp it till it BLOWS... so do not do that!

this is why i dont close the loop this way... lol

Guys

Just saying hello!

Hi guys recently I've build this toroid on a magnet speaker as Gilobob had build. The thing is that I connected it to a 12v battery worked for a little bit and stopped. Noticed that transistor and coil got hot.
Maybe Gilobob circuit should be with two transistors?
Maybe coil burned?
Any clue what happened?
Thanks

If that is a 2N3055 transistor, maybe it should be mounted on a heat sink?  I have always mounted mine on heat sinks either in a Bedini or a JT circuit.  Just a thought, there may be other things to deal with.

@ Jesus:

Hello to you too, good to hear from you.


@ Gadget:

Man, I got my 4 free 3 3/8" OD ferrite toroids today from them too.  My packing slip said these were made in Spain.  They came with a test spec. sheet, actually 3 pages of testing data that if Xee2 thinks might be valuable to other folks here, I can maybe put it up here somehow.

All I need now is a switch (on/off) that has a long enough reach to get through my wooden box side, and I am good to go.  Any toggle switch from the auto store will work fine.  I am starting on this after work tonight.  This will be fun!!!

Happy to report jeannas toroids from magnetics . the free ones WORK !. This little light i could not get it to light even with a fugi when the fuji lit every thing else . this is lit and i see now that its kinda yellowish  not cool white and not daylight but it lit right up .. did not count the turns but it used a roll of red from the shack minus about 10 feet before it hit the other side . I have not tuned it but its a success and i need some new bulbs . this one is about shot . and the other is a 45 watt  and the last is a little fl i got from goldmine  a while back . its bright ! I could not wait to test them so its sloppy . Next one will be pretty gold .
BTw i measured this winding for Milliamps and its putting out over 30ma on the secondary !, but its drawing 78 from the primary .. I can do better with the next one . I think this will be a good one to increase the charge time of a BCap.

@Pirate . Yep this is My second free order  Shipping was 11.98 for 6 toroid . There is a place for about 12 different part numbers . I wonder what the limit is on each . I'll order some more in a few weeks and shoot for 10 . It hard getting a price from these people . I have asked 4 times already and nothing but free samples . Well if they wana give em away i'll take em .
