nice pics/vid lespaul109, i think i understand now how this machine is suppose to work to produce free energy/over unity.fascinating idea!

Could you share? Most people do not understand.
Thanks!

hi all

just 2 cents, trying to harness the gravity power on a longer shaft. The setup seems to work, now lets do some measurement to see if Milkovic and Chalkalis together can do some usefull work.

any idea ?

Good night

ok, tested my motor that has two coils. Each produces 8v peak to peak @ 300rpm. My drive motor needs about 3v @ 600mA can some one tell me how to wire both coils using diodes and/or rectifiers and caps to power my DC motor? Color codes are:

Coil 1: Yellow & Black
Coil 2: Red & Grey

thanks,
jake

Hi Jake,

The best circuit for you would be a DC / DC converter because it can have a 85-90% efficiency. It is basically a switch mode power supply.
However, first you can test an important thing: try to load your stepper motor's two coils output to see how much output power they are able to produce and how much drag it causes to your main motor?

Just build a full wave rectifier with two diodes like the first schematic in this link shows:
http://www.electronics-tutorials.ws/diode/diode_6.html

Of course your coils will connect to A, B and C points in the schematic (they will have one common point of course) instead of the transformer secondary and you have to find the correct phasing for your coils. Not shown in the that schematic a puffer capacitor arcoss the loading resistor symbol, you have to use at least a 470-2200uF 25V electrolytic capacitor to filter the output "half waves".
So if your drive motor needs about 1.8W (3V @ 600mA) then your stepper motor output also has to give at least 1.8W or a bit even higher...
Do not care how many DC output voltage you will measure across your resistor load, just test. Use the P=V²/R where V=output DC voltage measured across the R load resistor you choose and vary.

rgds, Gyula

for what its worth.... here is my idea

You could use the 2-stage lever oscillations to actuate a Solenoid.
Feed the energy into a capacitor, and use it to re-charge the battery.

Then it is simply a matter of monitoring the level of the battery to see what happens.

simple, the weaker small motor will spin in high rpm which will keep the pendulum rotating. now just attach a generator to the pendulum's shaft for greater output.
i am not sure if this will work, but it is how i understand the functioning of this system.

Did you test the motorgenerator output with a connected load?
A suitable load must simulate the needs of your drive motor.
Use 68R at each coil. Check the the voltage at 300RPM.
If it drops to much, like 5V or so, then switch resistors to 27R.

My drive motor needs about 3v @ 600mA

This sounds terribly inefficient. You need a motor with much lower no load current.
Most of your input is wasted while waiting for the pendulum to return.
Find an old battery operated tape recorder and try the motor inside. Those are
usually of good quality and have a very low no load current while producing pretty
good torque and speed. All to save batteries...

One of the motors I have scavenged, uses only 6mA no load at 800RPM at 8V.
That's only 0.048W and it's a lot less than your 1.8W input.
And it pretty much tells us that your design is far from from being close to OU.
Your only chance is to slash input power to your drive motor by 40 times or so.

I can give you another tip for improvement.

Scrap the drive motor.
Mount a small electromagnet in the same area.
Add a small magnet to the pendulum. Ceramics is OK.
When the pendulum swings close to the electromagnet it gets
attracted to the iron core and procedes instead of falling backwards.
When it get top dead center you just give a small pulse to break the
attraction and there you have it, the pendulum falls into next loop.
The good part is that no power what so ever is used while waiting
for the pendulum to get into position.

The pulse can be self triggered by a small Reed switch, simple and good.
You only have to adjust voltage to break the attraction from the electromagnet.

@fatchance

can you send me pic of this recorder?

thanks,

FatChance!!! · « **Reply #54 on:** July 30, 2010, 08:23:50 AM »

No, I have no pics, I have scraped the recorder parts a long time ago.
But I can update you with new fresh motor numbers.
I tested my motor yesterday at 8V to get precise readings.
It uses 4mA at 8V = 32mW, while spinning at 1020 RPM.

0.032W vs 1.8W at no-load.
I do think you need go digging for old recorders and test their motors.
Please have in mind that all motors will use more power at load, aka kicking the pendulum.

Anyway, I can't see your device having the slightest chance of harvesting gravity power.
All gain from the pendulum falling down, is spent when swinging back up to the spin wheel.
You will make the device spin just nicely by the help of a motor but any load to the pendulum
shaft will prohibit the pendulum from swinging back far enough for another kick.
Just to make it spin at shaft load, you must increase the pendulum falling speed by increasing
voltage and power to the motor kicker, and this pretty much nails it.
You will only see the motor input at the pendulum shaft. No overunity or gravity power here.

I would like to have those motors for other projects also, but I'm not sure I know what machine they come from. Your motor does have some awesome stats though!

Yes...to confirm what you are saying.

ok, that makes more sense now

thanks a lot

@lespaul109

What makes sense?
The motor advice or my explanation of no excess energy?
