Hi.I have been playing around with the joule thief circuit and i am amazed at what i can run with it.Reed switch motors, Dc motors all work great so i thought i would try it with my Bedini Motor.I used my 4 rotor bedini as the test bed as if i got it going i wanted to see if it could run a slave coil as well anyway i am pleased to report that it can.
It spins really fast on 1.5v and can light the neon.
It spins even faster with the slave coil connected as both coils are pulsing the one rotor using 2.4volts.I will buy some new batteries and see if the slave will run on 1.5v.It will also spin two rotors off the one coil.
I have attached some pictures and may make a vid.:thumbsup:

jonny are you saying your running all 4 coils from one as a multi coil? Whooly crap man thats impressive. At that watts in thats prob the best solar Bedini contender i have seen man well done. Keep going.

Hi ashtweth.I am using a combination off two coils.The master and one slave.The other two coils are not connected and have been moved away so there cores don't add drag.I have used my four rotor bedini as it is perfect for testing this out as i don't know what this circuits limits are and i can add slaves and rotors as i improove it starting with some new batteries tomorrow.:thumbsup:

Great work johnny. It's always nice to see people doing new things. Or bringing back the old and hidden.

Hi.Here is my circuit diagram.:thumbsup:
@redeagle. Thanks:cheers:

@Jonny

I noticed that you were pulling you negative charging off joulethief driver from the negative terminal of the source battery rather than straight from the coil. That would seem to drop the source battery quicker. Can you clarify as to why you chose to do it this way?

You are using a car audio capacitor as well in your setup? I have been playing with supercaps with a bedni. Looks very kool. Thanks for sharing, please let us know how your load tests go with the devices you charge up with these.

Thanks

@redeagle.Not to sure what your refering to.The joule thief part is pretty standard apart from different type off diode and a cap.
@theremart.The cap is a 60000uf 15v electrolitic.The joule thief will charge it up to 15 volts in a couple off minutes if a load is not paced on the cap it would empty its contents on my ceiling.I got it from a car boot sale for 50p.Bargain.:thumbsup:

Hows about you loop L2,L3 and L6 too before the Transistor with a Diode?

Jonny----Great news!! I got mine to run finally. This works just fine. I used super caps front and back (an assortment of 2.5v -- 5F and 10F). I just charged em up and let it run. It was fun to watch. :dance:

@Joit.Thanks for the idea's.If anything spectacular happens i will let you know.:thumbsup:
@Lidmotor.Thats great.I new you would get it going when you could spend a little time on it.Any pics?:thumbsup:

@ Jonny---Sorry but it was such a mess I didn't take any pics or make a video. I am still scratching my head as to what is really going on here. I did make drawings of the setup so I could replicate it.

PS---Today I did the experiment again and made a video of it . Any comments on this are welcome. -----Lid

Great job Lidmotor:thumbsup: .Some very encouraging results and interesting waveforms you seem to be getting from your setup.The fact that your source battery is maintaining it's voltage is very good news.I know it's a bit early to shout "Are we there yet dad":thumbsup: but i think the combination off a Bedini motor with the joule thief is a winner.
It would be interesting to get sephiroth's opinion on the waveform.
I hope you are going to leave it running for a bit and see if the voltage holds and maybe you could post your circuit diagram and data here for reference.
Great work once again regards jonnydavro.:cheers:

1>50>500. Its true.

@ Jonnydarvo---- Well I discovered why my experiment seemed to not use any energy. The battery in my volt meter was going dead and it gave me a false reading.:mad: The experiment was still a success and I'm glad that I found the problem before I got too excited. It was efficienct but that's all.
Today I setup the JT to run on just one super cap and found that a cell phone solar charger works well with the system. This 'thief' will run for many hours on a 5 farad 2.5v cap. Zap the thing with the energy stored in the internal lithium bat of the solar cell phone charger-- and off you go again.
The other thing that I did today was play with a Peltier module to harvest energy from the environment. I had no idea that they could gather energy through induction also.:thinking: Here is a video of what happened:

Hi.Today i made a USB Joule thief Bedini motor which charges a 12v battery from the usb port on my laptop.I can think off plenty off other things that could be run in this fashion.Here is what i have up to now.Here is a video off it running.
