Help with Building an overunity device

[grant]

Ok I order some thyristors and Zener diodes I just need to wait for them, I also successfully conditioned a220uF capacitor (it is sitting on a table slowly charging itself from 0v) I also built a kromrey generator but I only have two 220uF caps which probably isn’t enough

This is a good educational project which seeks to achieve the same goal as the "Imhotep" style oscillator

The NPN conducts charge away from the gate very quickly resulting in a very sharp voltage spike. Works well (produces 600v+ when built right)

As mentioned see the papers by Julian Perry - he picked up where Bedini left off  Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

it looks like this is just a modified bedini motor, I previously built a kromrey generator however I could not get it to go a fast enough rpm, and the bedini motor is a much better device anyway, I will build the circuit but I will need a bigger cap dump as I dont want to condition my batteries directly. I also have all the parts to build it

It forces a fast fall time. Open to interpretation though.
Articulate your objective! (not here (unless you'd like)

I hope the direct replies from myself and Green are appreciated
Honest advice is rare ime.
It'd be nice to get a reply to my PM.

Having messed about with this circuit for a while now, I would say the following: Split the cap dump and cold elec gen into two completely separate units. This will simplify things greatly.

The cap dump can simply be a self-contained box with two connecting wires to the battery, and that's all. It contains a HV booster DC-DC converter to give say 150V, which charges a 470uF 160V cap through a 30k resistor. A neon triggers the thyristor which discharges the cap back to battery. Thyristor cathode to batt+, anode to cap+. (cap- to batt-). It will trigger about once every 20sec with these values. Continuous desulphation!

The resistor value should be such that the charging current is always less than the holding current of the thyristor, so it switches off once the cap is discharged. The neon should flash and trigger the thyristor, but in the case where it stays on a NPN HV transistor could be used to amplify the current to the gate. (Also add a 100R resistor to gate to limit peak current)

Another thing: Put a low value resistor (say 10ohms) in series with the input to the voltage booster, with a zener (say 33V for a 24V system) across the input to the boost reg directly. This prevents overvolting the device when the cap discharges.

Be careful of going too high on volts & energy with the capacitor, as this can be dangerous if the battery is gassing and a spark is caused in the battery. Always be cautious!!

hello again, I have built a bedini motor circuit, I've just built a quadro-filar coil, (an between of 2 and 8 strands) I am using the circuit detaileed here: https://www.thedoityourselfworld.com/art...p?id=11558
of course I'm only using two of the strands, I also tried using all four (2 in series for trigger coil and 2 in series for power coil) and I replaced the 1N4001 diode with a 1N4004 instead,
everything else is the same about the circuit.
currently it does not work, my O-scope shows the transistor is triggering, but there is no collapsing field likely because it isn't turning on enough or is turning off too slowly,
any advice on getting it working?
right now I'm not worried about cap dumps or overunity I just want it working, and conditioning my car batteries (their SOH is not great)
I have 4x 15000uF electrolytic caps (the same as john bedini used) and lots of different Zener diodes.

What do you mean when you say it is not working.  Is it not causing the wheel to spin?  Is it not charging the charge battery?  My first suggestion would be to reverse the leads from the trigger coil.  What exactly does the scope show when you say it shows the transistor is triggering?  Also check that you have the diode in the right direction.  Does adjusting the pot make any difference?  What kind of magnets do you have on  the wheel.  They need to be regular ceramic magnets, NOT neos.  If you disconnect the charge battery does the neon bulb flash?  If it does then quickly connect the battery back up so you don't blow the transistor.  If the bulb flashes then the circuit is working.

Why do they need to be regular ceramic magnets, NOT NdFeB magnets ?

[citfta]

Hi Verpies.

The only purpose of the magnets is to trigger the transistor.  Using neos make it much harder to get the circuit to work properly.  The impulse from neos is just too strong to properly trigger the transistor.

when I say the circuit is not working i mean the wheel does not spin, nor does the neon light. according to the scope the voltage across base-emitter goes +- 0.65V which should be enough to trigger the transistor, and during the positive half the voltage across collector emitter drops to 0V
