Hello
I have a question, where does the excess energy come from to charge the 2nd battery? I was looking at the last circuit nastrand2000 posted and Im not getting this.

Hi ac
Good to have you back. I thought I was the only dumb ass who wasn't getting it.

In regards to winding coils check out this site.

They really are quite simple. Make sure you take note of whether you wind clock wise or anti, and finish the ends apart so you can tell the start from the finish. Oh and scrape the coating off the ends before you attach hookup wire.

Ive got my hall switched motor crankin now, Its unbelieveable how fast its going. Its drawing about an amp, but this is adjustable by simply changing the position of the switch. I've had it as low as .4 of an amp. I ran it for about half an hour last night and everything remained dead cold, and battery didnt drop any voltage, infact it went up .01 of a volt. As it gets faster amp draw drops till it settles on a spot related to positioning of sensors.

I still need a way to harness this voltage coming off the secondaries. Its up  to 60 volts now on the digital meter. I think whats happening when I hook up my analogue (needle) gauge is the spikes are being earthed because it drops to 5 or 10 volts. Theres definately more than 10 volts coming out though. When I hold the output lines my hands start to go numb with tingling. I will post some schematics and a video in the next couple of days and hopefully some one can help me refine and/or change the setup to benefit from this voltage spikes.

Hi Ren
Good to hear you're up and running. What # Hall IC and transistor are you using to switch the coil on? Are you using any diodes, heatsink,or resistor? Do you have a schematic of your circuit?
Peter

Hey tropes. The hall im using is a unipolar hall effect switch rated from 3 to 30 v I thing. Here is a page with all the tech.

http://docs-asia.electrocomponents.com/webdocs/002e/0900766b8002e123.pdf. I brought from rsaustralia.com for about 3 bucks each. My circuit is essentially the simple tim harwood adams setup I posted a couple of pages back. One exception being a diode joining base and emmiter allow current to flow only from base to emmiter. I will draw a full schematic and post with a video soon. The seconday coils arent connected to anything, they just flow back through a series of bridges.

oops transistor is Power Darlington Transistor  TIP147 PNP, also about three bucks.
