I have not   tried an incandesent  bulb with theMOT yet

I will  try it later 
RIght now something is  not quite right  with my  3055 board
It  is not working as well as it  first did .
I  get  good voltage with no load .......but it  drops to almost nothing  as soon as I put any kind of load on it

I can't even get  it to light my  CFL anymore.

@Gary, did you fry the 3055 with the mot?

Hi everybody,
I am compiling pictures and text and will be busy for a while, but I named this for gary and I thought I should post it now rather than later.
This is a spool of magwire being used as an inductor to light a light.
It makes a beautiful wave and shows voltage even while lighting the light but it doesn't light it very brightly.
It is on the left and lights 2 in parallel; the 18 leds in series are from 2 toroids on the right.

for now...

A buddy of mine on Youtube posted this and asked me to bring it to your attention:

He did not film this and it is in some language I do not recognize but it is what appears to be an earth battery, joule thief, spark gap (Jeanna will like this) and God knows what else and they are lighting about a dozen incandescent bulbs from it.

It is a 7 part series (the link above is for part 1) and maybe someone here will be able to figure out what they are saying.  It is very interesting to say the least.  I can't quite figure out what they are doing even though I recognize some of the components.

WOW! Just up to part 3 now. great watching!

@Gary,
I went right to walmart when you first told me about this. They have some led spots there, but 10 leds, not 60. I would like to make this one for some reason anyway. I want to place another order from the chinese led people soon. I think I will get 500 I think for $35 or $40. Once I get the light fixtures right, I will change the whole house to led lamps. I also want to try to take a frosted edison bulb apart and see how they do in there esp with a jt for power.

Is  this  what you are getting ?

I have ordered  a couple of times from them


what about getting the light  fixtures right ?
Are   you  planning on   running  the JTs  at higher  voltage or  putting  a  step  down  transformer  in each lamp .
In a way  a  transformer might  be nice ....... you  would have the option of  adding a battery  for emergency lighting  .

Xee,
I am wondering if you can get the very high voltage I got at about 33.8 ohm?

I went down to 20 ohms and the output did not go much over 250 volts. I do not think you were getting any significant amount of energy at 600 volts else you would have been able to light the fluorescent tube.
