@ jeanna

are magnets on the pulse motor

I think he should have added a bit of explanation in the video. But, I think there is at least one magnet on the rim of the rotating disk and that by positioning the reed switch at the proper location when the magnet closes the reed switch it sends current through the coil and either pushes or pulls the magnet (depending on which way current is flowing) thus giving the rotor a small push (or pull).

Mark,
1- What is the base resistance?
I was amazed at rosphere's base resistance. Maybe that is part of the trick??

2- What is that dark green round thing? - Is that the pot?

One more q for now,
3- Does your coil get warm at all?
I made mine wrong but put it into the breadboard anyway and the bjtl did not light, and nothing seemed to be working,  (I used a croc wire wrapped around 4 times as the secondary and nothing there...no surprise),  however, when I pulled it out, the coil was warm... so, something was working.

thank you,

The green thing is indeed some 300 ohm pot. It did nothing to the led intensity, i assume that i am now even close to the proper resistance value.

I did not notice heat but usually it means there is a short somewhere .

Usually i don't put the secondary on unless the basic joule thief led works.

I can't wait to put the coil inside , to see if the jt circuit is blind to it .

Because the field inside , is way more powerful inside.

I will spend all night on it , i may have a few video .

If i could find a filament bulb ...
