A3144

@romerouk,

Back a few pages you posted a drawing of your switch.
The switching transistor inside the A3144 is a NPN
capable of switching 25mA. In your drawing you did
use a 100 Ohm resistor. Did you use this resistor
as a pull up from pin 3 (collector inside A3144) to
the positive rail?

I call it pin 1 the voltage in, from plus goes to pin 1 thru a 100ohm resistor.
This schematic was used by many others in the shorting coil experiments.It is simple and works great.For my next build I am going to use proper mosfets with dedicated driver circuits...

Hi Romero,

CONGRATULATIONS!  You seem to have a COP=2 setup!  Very good.

For any naysayers a possible looping should be practical by using a DC/DC converter, such off the shelf units have at least a COP of 0.8 i.e. a 80% efficiency (or higher), this means the resultant COP still remains around 1.6 (0.8*2) and because you showed 12V output at 2A current (24Watt) the remaining available extra power (beyond the output taken for selfrunning) is at least 5-6Watt:
you can win the overunity price right now!

Here is a possible DC/DC converter I think would be good for looping back your output to input:

rgds,  Gyula

Looping or using a scope to measure the output power will tell the true story.

The input power (~ 11.3W) is going to be fairly accurate because of the DC source. However Gyula, you should be aware that multiplying an average current by an average voltage of an output produced by induced currents in a coil, is not going to have a power factor of 1, and therefore the simple product of 24W will not be accurate.

Judging by the intensity of the bulb and assuming the efficiency to be 80%, the true output power is likely closer to 8W or 9W.

Nice job on the build R.

I have asked this before but if got missed in the exitement . All the rotor magnets are same pole face up . I feel that this may mean that from a given generator coil , the out put will be not AC , but pulsed DC . If this is true , then a BRIDGE RECTIFIER IS NOT NEEDED.It can be replaced by a single diode . Can anybody confirn or deny this please? Single diode equals less volts drop and higher output .

Neptune,

A single magnet passing a single coil makes AC You do not need NSNS to make AC. What controls the wave form is the direction of motion.

As the magnet approaches the coil it generate say a positive pulse. At TDC there is zero induction, As the magnet recedes from the coil it generates a negative pulse (depending on the magnet pole and the hand of the coil)

Hi folks, Hi romerouk, thanks again for all the information and videos.

I recall reading something from Muller about hardened steel ball bearings and also tubular steel cores could be used instead of the magnetite that he used.
Though I don't have any of the above, nor do i have a sufficient supply of ferrite cores.
All I have are steel bolts, so i will use those for the time being.
I have 1" diameter neos I'll be using, with 6 neo magnet rotor from another project.
