Thanks Rich...got those.

Inductance is the most important measurement I need however, and failing that, I can calculate approximate inductance from the coil dimensions I mentioned.

Darren

When I get time I'll check the resistance and inductance of both coils. I gave resistence for both coils together, didn't think to do it separately.

Also, I've often though, "couldn't you have just counted turns when you wound?", And yet, I did not. Sorry about that, so no turn count. It's not too many though, we're not talking thousands, couple hundred on primary, max, little better than double that on the secondary.

Not that that helps.

ya .. i was wondering the same .. it goes w/ what many of you have been saying ..

i mentioned this in the previous thread - http://www.overunity.com/index.php/topic,2235.msg33932.html#msg33932 

it could be the ion effect, superconduction . etc who knows ... BUT i am inclined to think that we are using a "brute force" approach to accessing this advanced energy .. if we extract this energy correctly, the device should actually be cool to the touch (again a guess).. .. many things could cancel the flux .. certain coil configs can do that too .. mobius, etc. I wonder how using crystals or fiber optics will play a role in advanced Free Energy extraction.

i am currently working on really looking at the SM vids frame by frame to see if i can make decent drawings of the devices .. they show some very good close ups of the 15" coil .. but i am also looking at the open frame TPU vids also to look at the coil configs and wiring ..

(something i found interesting .. if u look at the very OLD one, where he is in a workshop showing the small device flipping 180 degrees; if u look at the frame when he is flipping the device, u can see a metallic central vertical core. .. like a tesla coil)

ps .. i cant download the vid from the link or other vid downloaders .. it keeps erroring .. may be a prob on my end.

Folks it just occurered to me, that SM used to talk about Vacuum tubes right, well how do they function, they produce heat, same thing what Otto and Roberto have found out,
what if this is what cancels the magnetic flux and speeds up our electrons, same as what happens ina vacuum tube.
what about the imploding tv set, if the coil malfunctioned or there was heat involved, which set things in motion, wow.........................

refer to the heat magnet motor, you bring heat next to iron, with magnetic field near it like a magnet, and what happens, it looses it magnetism, so im thinking along those lines:-http://scitoys.com/scitoys/scitoys/magnets/magnets.html

Also we know that these things produced heat, so there's the other clue.

Kind Rgds,

If you keep cooking your mosfets try the IRF730 they seem to perform well for me.

I will do some more test later in the week to verify the seed.

Cam

Hi Cam,

I asked Otto a few days ago about the IRF730 as it has a even faster rise time then the IRF840 (10 ns against 23 ns), but according to him the IRF730 doesn't work properly for this setup. Input capacitance had something to do with it he said.

As per the document
Secondary 10.5m of .35mm wire
Primary 4.2m of .5mm ? 1mm wire
Control coils must be mass equivalent:

.5mm= 24gauge = .00122lbs per ft
1mm= 18gauge = .00492lbs per ft

4.2 meters = 13.777 feet
10.5 meters = 34.44 feet

13.777 ft * .00122Lbs per ft <24 gauge>= .01586lbs

.35mm = 28gauge = .00048Lbs per ft

.01586/.00048 = 33.04167ft of 28gauge

The doc math closely matches using 24 gauge as primary and 28 gauge as secondary.

Cam

Thanks Cam, Had to recheck my wire gauges after that, because my weight is a lot higher. 12 grams per coil segment(primary and secondary), yours are equivalent to 7 grams per.

so, I have mine wrong, using the rat shack stuff. Shoulda checked ahead of time, as my coil lengths probably are not ideal with these gauges.

Turns out my gauges are 22 and 26, respectively.

Much heavier gauge on the primary, and slightly heavier on the secondary. So my coils are bigger. We'll see the effect.

got my drivers, Still haven't gotten my fets yet.

bad shipping luck.

However, got lotsa extras so I can burn as many as I want, when they come. As now roberto is testing a new fet which seems even better.

Better make my board with sockets for the fets.

I was going to wind a coil, but I don't have the #24 wire, so I decided to try and calculate the inductances.

What I came up with:

Primary: 15.5uH, 0.36 Ohms, [165.32 inches of #24 wire], 90 turns

Secondary: 107.8uH, 2.28 Ohms, [413.28 inches of #28 wire], 248 turns

I used a coil length of 1", and a starting bobbin diameter of 0.5".

Hopefully a few people will add their specs for comparison.

Hello All,

I'm finally back from my weekend trip and thought I would take the time to draw up the the circuit diagram for my control circuit.

It uses the mic4427 MOSFET drivers for the IRF840 MOSFETs. For those of you wondering where to order them, they can be purchased inexpensively from this website here:

http://www.arrow.com/

Search for mic4427BN. That is the correct chip.

I am currently modifying my control circuit to output extremely small duty cycle square waves (500 ns pulse width) to conserve input power. My firm view is that we only want to put in enough current to load the coil inductance and no more. Any extra input will simply be wasted. The attached circuit diagram does not include the ICs I will be using for the pulse width control but I will be using the 74HC423N chip. It is a Dual retriggerable monostable multivibrator which, using a resistor and capacitor allows you to vary the output pulse width from a minimum of 75ns and up. The mic4427NB drivers need a minimum 500ns pulse width to turn on and off properly.

As soon as I have finished the modifications to the control circuit, I will post an updated circuit diagram.

The board I have currently runs on a single 9V battery and the input frequencies are controlled by three separate battery-powered function generators, which I bought from here:

http://www.electronickits.com/kit/complete/meas/fg500k.htm

They have a range of 1Hz to 1MHz. Above, 500k, the square wave output really breaks down but since the FET drivers are comparator driven, it won't affect the switching of the MOSFETs.

That should be all you need to make this circuit. If you want to use 555 timers, make sure that you put some capacitors in parallel with the power supply inputs to the timer chips because the FET drivers draw a lot of power when they are running. If you have any problems, PM me and I'll see what I can do to help you.

God Bless,
Jason O
