Power ratio over one

Hay Stefan:
Sorry for the delay. Power went out last night and again this morning (darn squirrels).

I originally used a one-ohm shunt. The current reading comes back at .002 total amps. I know that isn?t right. That?s why I used the 16 (8 each way) LEDs that are in parallel, connected in series with the 14 LEDs. I burnt out many LEDs experimenting. A great deal of time was spent using a load to verify the amperage, and voltage.

?The current inside the LEDs should really follow the voltage of the coils
and be not so noisy...?

To further confuse the issue, click on view, format screen, 4 waveforms overlapped. Look what happens with channel 1 and 2. As the voltage goes up the amps go down.

To add even more confusion, use Ohms law to calculate the moment-by-moment resistance. The resistance changes considerably.
Yet even more confusion comes from rocking the magnets by hand, to physically feel for resistance, there isn?t any.

My brother in law arrived in town a few months ago on vacation. He is an EE that designs and builds custom circuit boards for the Robotics industry. He said that he would show me the errors of my ways. The first day of testing, he determined that it must be the Windaq hardware. He spent a few days going over the schematics. He determined that the circuits were correct, so the errors must be from an incorrect setup. By the end of the second day of testing he walked away saying ?we must be making a mistake, we have to be making a mistake!? I just laughed!

So, this is why I straight out say ?I do not understand resistance.?
You are asking good questions. Unfortunately, I cant give good answers!

@Stefan

The basic question I would have is this. Regardless if the LEDS are connected to the gens or not (we know they are not), can a 1.2 volt dc battery light up so many LEDS, and if it could, for how long. If the device can run for longer then that theoretical time, then there has to be something here.

Actually, Plengo is doing something similar with many LEDS in the miniTPU thread.

@HG

When you turned the genmagnets by hand, was there a load connected? It's funny there was no resistance. When I hand turn any of my DC motors with a load on it, you can feel the drag (resistance) . Increase the load and you'll increase the drag

This tells me the design can be improved and that the magnets, even though they are rather far from the coils, the coils are still picking up enough energy to light the LEDS. Crazy.

It's a good thing Stefan and company are here to guide you through the OU aspect of your device. You're in good hands indeed.

So.........................did you figure out a name yet? lol

@All

HG's device is using 4 micro contacts with a swinging plate that activates two micro contacts per side. I am wondering,  is there a way to replace the micro contacts with optical senors in order to eliminate the banging action and noise. Or could the banging mechanism that stops the magnet so abruptly before changing direction, then aid in the overall process towards OU.

Hay Group:

As part of my critical thinking on the subject, I would like to share one of my conclusions.
My test cell is a rechargeable 1.2 volt, 500mA AA cell. This equals .6 watts. Yes, the wattage can be higher, that's why I would let the apparatus run for ten to fifteen minutes before I would take any measurements.

The loads are as follows: The large coils load is 20 LEDs forward an 20 reverse. The operating voltage is 3 to 3.8 volts, and .025A. Using 3 volts and .015 amps as the low requirement, the wattage required is (20 LEDs x 3 volts) = 60 volts; the amps are .015, = .9 watts.

The center coil has 14 LEDs forward and reverse, at 3 volts each, the voltage is 42  at .015 amps = .21 watts.

The center coil also has 16 LEDs, 8 fordward and 8 reverse connected to each other in parallel. At 3 volts and .015 amps each;   (8 x .015 = .12 amps) 3 volts X .12 amps = .36 watts. The total for the center coil is .21 watts plus .36 watts = .57 watts.

The small secondary unit is a mixture of red, white, blue and red LEDs totaling 36 volts. Using 30 volts at .010amps, = .3 watts.
.9 + .57 + .3 = 1.77 watts. A fresh AA cell is .6 watts. These calculations don't take into consideration the power needed to operate the apparatus

Wattsup!
I am not sure what you mean by the LEDs are not hooked up to the output coils. Of course they are. I have done a few experiments with just one, or two output coils, but there has always been a load attached. Almost all my experiments have all three coils operating with a load. The power Factor is the same using LEDs or a resistor as the load.

Absolutely the design can be improved. I have considered optical sensors, but I also have to consider that the magnets will be harder to stop and reverse, as you just mentioned.

Keep in mind that you can?t use the same principals, for an airplane, that you would for a space ship. Referring back to your example of apples and oranges looking similar but are quite different!

One other thing to keep in mind is that the magnetic field isn?t collapsing in the output coils, like it is in the driver coil. My experiments lead me to believe the magnetic field dissipates rather than collapsing in the output coils, due to the low operating Hz.

No, I haven?t came up with a name yet! I agree this is a great site!
