Mechanical Joule Thief Charger

This is my little pulse motor run mechanically with a reed switch instead of the transistor circuit. This made things even simpler and allowed the second unused trigger coil to be converted to a charging coil. The setup runs on one AA battery and drives "Maggie" to produce light from two 3v Leds. That is also why I call it a "mechanical Joule Thief" ---it bumps the 1.5 or less voltage up to 3 or more mechanically.

Hi Lidmotor, one question i have. Why you do not put on the other site of the coil also a wheel? Would it not be more efficent?

[Lidmotor]

rensseak--I have tried that and it doesn't work very well. Thanks for the suggetion though,

[blulander1969]

also a little info on the bridge rectifier would help me :-)

bullander--- the bridge rectifier is just a just a small low voltage one---any one will work or make one. The cap here is a 35v / 100uf.

awsome,,can i add a dc motor for generating rigged up to that pulley you got there,,, but run in series---> generator-reed switch-hard wired cell charger as transformer------- then you can with this setup you can pulse charge with the dc generator, and then as your pulse chageing you will collect a back spike off the secondary........ plus the pulse charge wont drag down your system as much, this is a relly nice and neat setup, great job.

[Lidmotor]

crob227---There are all kinds of things that could be done with this basic setup.

[blulander1969]

Thanks I will see what there is at the local maplins :-)

[blulander1969]

hi lid could you tell me what cap u used here please :-)

Ben---The coil is a stupid simple one but it works. Radio S-h-ack sells a package of magnet wire ($7) that comes with 3 coils of wire of different gauges. The coils are :40ft.22ga,75ft.26ga,and200ft.­30ga. Make one bfilar coil out of the three. Solder the 22 & 26 together to make one long wire and wind it up with the 30 on a spool. Add nails to the core or not. The 30 ga is the trigger wire. The 22&26 make the drvier.

These experiments of yours are incredible, and very proffesional.

Great job! Im not getting great results with my coil: 800 windings, 26ga-28ga.

I should put a video up, what does your current coil consist of? Looks like lotta windings with 28-30 ga.

Ben.
