Mechanical Joule Thief Charger

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 :-)

[Lidmotor]

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.

[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 :-)

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.

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.

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.

Haha brilliant!

[ZincFold]

Very cool! I agree with tj7729. If you utilize the back EMF from the powering coil before it hits the reed switch it should reduce or eliminate sparking in the reed switch for higher voltage. Thanks for sharing ;-)

[Lidmotor]

ZincFold---Thanks for explaining where the pull off the BEMF to reduce the sparking in the reed switch down.

[tj7729]

I'm glad you've done this one with the mechanical switch...

[Lidmotor]

tj7729---This seems to work quite well. I had to play around with where to put the reed switch and the little tuning magnet. Notice the stange place that it had to go Anywhere else and this one magnet motor would not work.

[tj7729]

u should still be able to add another diode/cap/ battery charge combo off the one end of the reed switch...I'd be curious how many milliamps u'd get off that one.

[Lidmotor]

tj7729---Thanks. I will try that.

[rroge5]

what youve made is a electric motor, a brushless motor. i cant think of any electric motor like it =D

[Lidmotor]

rroge5---I don't think that this is unique but my version of it sure is. Google "Rube Goldberg". I made an interesting device to do a simple task---in a very unusual way.
