Hey Visse looks good.
I changed over a monopole (16 magn.)to this config. just to have a working model to go off of.
I am building a bigger wheel with bigger coils it will just take more time then this.
I know John said a smal wheel won't work as well but it seems a lot of us are trying to do just that.
I am building the Bedini/Cole circuit for this as well and any help will be greatful,
as the electronic side is just starting to make more and more sence to me... it's just taken two years.
I have to make the small timing wheel and will try to find some magnets for that today. I bevieve I can find those locally.
For now a connected a monopole circuit just so my kids could watch it.Last edited by Rl2003; 12-06-2010, 03:19 AM.

Hi Wings,
Don't get too hung up on the maths. 34.7W is not what's charging the batteries.
It's what you can get out of the batteries that is important.

I am correct?

Hi Timm,
Looking good so far.
If it were me, I would get the circuit running on the bifilar first to get familiar with it. Then once you have the circuit working, you can change the coil out.
I have a question for John about the neo magnet on the back of the ceramic, but I'll wait until I get to that stage later. I have a funny feeling it's not what most people think it is, but I'll leave it at that for now.

Aaron's challenge doesn't define the coil. I've used my SSG coil, 850 turns of bifilar. As we proceed with this build, is this sufficient ? or should I start right away with a quadfiler ?
This is a 3" spool piece with 2" extended ..
See picture for small neo ...
This is the physical build... the electronics are ordered. I didn't have the NPN,PNP combo.
PS... John K... I'm following you ..
Thanks,
Timm

The Amp meter was between the relay and the charge batteries.

Matt,
Ok I'm going to try that circuit arrangement as soon as the snow stops. I think I have a ss relay very close to that. If it's working then use it. now is the current meter on the input to the joule thief or on the output side. No I was not talking about that kind of arrangement, but I want to do some experiments here with this if I get a break from all this snow. OK Vissie I see what your saying.

It's at 42.5 volts switched 3 times a second........ My machine does not use any power to switch as the power is derived from the single black wire.......
John B
This is how I was doing it last night, is this what your talking about when you say "Does not use any power to switch"?
Essentially everything I am using ends up in the charge battery. The switching is potential based not current based.
Or is there more we need to take in to account?
Thanks

Hi John.Originally posted by John_Bedini View Postnvisser,

Is what you posted correct or not? .
John B
I think the circuit is correct like you described it. I just tuned the circuit upside down so that it shows normal with positive on top.
Matt tested this circuit and it looks like it works fine.
We are also working on a zener mosfet circuit like you asked, but it looks like we will need an extra small bipolar transitor to switch at least 10v to the mosfet gate to make sure it switch on fully.
I repost the circuit here for 42.5v dumping.Last edited by nvisser; 01-24-2015, 08:55 AM.

Big Bedini Machine
One last thing, if you guys would clean up your wiring and get rid of the clip leads you might see something different. Clip leads will lose way to much and spread the fields in every direction, ok for a test but not in the final machine.

nvisser,
It's at 42.5 volts switched 3 times a second. Remember how big the machine is and the coils as it does make a difference. The reason I looked at the circuits posted was to see which pole shows in the drawings. Is your battery symbol correct or not ?. I have said for a long time that you must look at the total potential across the batteries in the output. My machine does not use any power to switch as the power is derived from the single black wire. And yes it is over 3 mega joules in 24 hrs. If I use my big batteries much more. At that point I would upgrade all the wires on the output. A transistor has to much of a voltage drop at that point. Is what you posted correct or not? I must go plow snow be back later. John K read my last posts on where your pole piece extends.

Coil wound
I have my coil wound - 2 windings of 0.75mm (AWG#20) & 2 windings of 0.5mm (AWG#24). I still need to cut up the R60 rods for the core.
@John B,
Just want to check before I super glue the rods in. The end of the coil that was wound on last faces the rotor magnets, right? If this is correct and since I'm in the Southern hemisphere, the core needs to extend out of the same end, which faces the magnets.
Since the height of the coil is 3.5" (90mm) I was going to cut the rods 5" (125mm) long. 1" (25mm) of the core will extend out of the coil facing the rotor magnets and I'll leave approx 3/8" (10mm) protruding out the other end of the coil so I can bond the steel sheet to the core.
Pic of coil attached...
