Joule Thief

Thanks gadget,

It was the exact same gauge. and the same toroid and (almost) the same numbers. I found that the wire ends were too close to each other and kept shorting when I was taking measurements, so I unwound 2 secondary to 68 instead of 70.

I used the 2n3904 which gave me better results, but I plunked in a 2n2222 (what hazens used) just to see. the voltage went down.

I should have used the 10Mohm resistor on the secondary to look at some lights, but maybe tomorrow I will find it. It is on another breadboard around here somewhere. 

Anyway the main reason I took the pic was to show the screen of the new scope.

Does anybody have advice on how to get a neon to light here? I think it should be lighting, shouldn't it? There is no circuit for it. I just have the 2 pickups in next to each other (series) on the breadboard. There are 2 wires taking their output to the bridge when I am measuring that through the bridge. I pull the wire when the scope is on. Should I do something else to make a circuit? It seems complete to me, but ...

thank you,

   Hate to rain on that one but you can hear the rotor. What can be done with video these
days, that is nothing really. Good job tho.

Hi every one .

Can someone with an oscilloscope post a picture of what's going on between the emitter and ground ( - )?

Won't that be different with everyone's different set up?

On my 7,7,68  pictured above, the emitter says 8.9v (!!) and is mostly straight with a little ripple rising up pretty frequently but it is small. The scale is such that the little ripple is 8.9v. But I am not sure if I am measuring what you want.

The high voltage surprises me. I checked the base and it says 2,5v. Hmm that is a lot of draw just for the transistor with no light or anything. Isn't that interesting. Sorry, no pic tonight. too hard still. I am balancing it on my knee while holding the camera. I don't want to drop either one.

I don't know it this will help.

@ jadaro2600  and jeanna

  I usually consider the negative side of the battery to be ground. The emitter is connected to the negative side of the battery. Since they are both connected to same place, how can there be a difference in voltage between them?
