Joule Ringer!

not to take off topic, but bifilar wound with copper et other rings of Steven Mark's TPU, wound with maybe copper and tinned? But, seems dissimilar copper et other is significant?

I been asked to clarify EXACT coil winding details to make these bifilar coils. Is it 2 wire pair wound up at the same time OR 2 separate layers with the second layer wound counter direction and back.

Thanks MK1!

Back and forth 2 wires at a time , at least 6 layers .

Well my first replication failed . It goes out as soon as the battery is removed . There are some varibles not clear . the coil is clear . the transformer is not . those AA versions are hard to find items as i checked three stores and a camera center and they are all aaa versions with tiny transformers . Sooo. I only have two AA versions and i wont take them apart cause they are already in fixtures and stay lit 28+hours for emergency . If lightsaber is watching i would love to have a camera circuit from your source , Also i am having a hard time finding small 10000uf caps at 10 volts . not a common part in this area. will keep at it .

Caps not important usually 16v are available everywhere the more uF the better its only for storage not a timing device. The little transformers need more clarification i  agree but in essence the bifilar MUST see like 500v spikes because this is the only thing that recovers used energy in the circuit and send it back to recharge the cap like a JT OR it goes off within 1 second under load and no battery. Some people are bound to have trouble getting this to even oscillate especially  using other transistors. Remember at heart its a Joule Thief and all the usual biasing and feedback caps and resistors can be used to get the tranny working.

Later when the finer details worked out. Existing JT's can be enhanced to self runners:)
