Bedini Scope Shots

[NXUS]

Hi, sorry if my prievious post seems a little out of context, I am new to this forum and to its posting idiosycracies. This was a response to an older post asking about electron propigation in a wire.

Me again, I have a question this time. I have scanned trough some of the posts on this thread and are some of you making that fan based on bendini circuit that imhotep posted? If so , any success, I just started looking at trying to reproduce it also. Any feedback would be appreciated.

A comment on the signal you got on your scope from the antenae and ground connection. There is a lot of energy in the air and if you are near any power lines or heavy industrial equipmemnt you can get a large amout of induced signals, the air is full of energy, so is the ground. I installed a fiber cable that ran parallel to power lines for several kilometers, and even burried 4 feet in the ground, enough energy was coupled to it to develope over 2000 volts and enough current to produce an inch long arc when i grounded it. Picture me supprized when i was holding this in my bare hands when it happened 0-0.

The difference you noticed between the scope and meter would be due to the differences in loading, the scope has at least a 1-10 meg input impedance the meter maybe 20 kilo ohms. Also the scope shows the peak voltage whereas the meter usually registers the average. You probably already know all this but just figured i would give my 2 cents worth

Cheers!

Hi BinzerBob,

Thanks for bringing that up!
I found that technique useful for finding the peak current when coil shuts off. I hadn't actually tried using the scope to verify my meters yet but it is good to know they are fairly accurate Are those digital meters you are comparing by the way?

Looking forward to your shots!

Yes what I have found With the 1 ohm resistor in series in say any part of the bedini motor or self oscillating circuit is

a) you can use a digital volt meter to read the voltage across that 1 ohm resistor , the voltage you read is equal to the average amperage passing in the circuit.

b) If you hook up a scope to that resistor you will read the instantaneous voltage accross it which is equal to the instantaneous curent passing through the circuit. and if you calculate the average of this signal, you will get what the digital meter was telling you in (a) above.

C) If you hook up your digital multimeter in series (in front of or behind the 1 ohm resistor or if you take out the resistor and replace it with the digital multimeter) and you measure Ampreage DC, you will get values very close to values you obtained in (a) and (b) above.

d) The Analog amp meters give you a result very close to the digital multimeter as well.

So really all the methods used produce a similar value. say + or - 5%


CAUTION CAUTION BUT read below....

Also..... if you hook up a diode in series with a capacitor you can charge it up to the maximum voltage of your bedini motor / pulse motor voltage spike.... So if you don't have a scope and are wondering how high of a spike you are getting you can use the capacitor diode method. I found this to be very accurate to what the scope was reading. CAUTION!!!!! CAUTION !!!! CAUTION!!!!! if you are using this capacitor method be very VERY VERY CAREFUL... TODAY I CHARGED UP A 2000 MFD CAPACITOR TO 370 VOLTS THIS WAS VERY VERY VERY DANGEROUS. When I shorted it out it created a very loud noise and dangerous spark and got the wife running downstairs. USE A SMALL CAPACITOR SAY 100 uF or smaller to capture a peak voltage. AND MAKE SURE YOUR CAPACITOR CAN HANDLE THE 300v OR 400v OR IT WILL EXPLODE!!!!

H wave motor on, Sine wave motor off

Hello all,

I was poking around with the scope and I wanted to see the voltage of the SSG motor when it was up to speed and then switched off. Basically I wanted to look at the sine wave...

Then I wanted to compare this wave to where it fits on the h wave. All I did was turn the motor off to look at the sine wave and on to look at the h wave. The sine wave sits right on top of the h wave hump.

Take a look. YouTube - 2008-11-20.wmv

The top of the h wave is the voltage spike... The hump of the h wave is the magnet approaching the coil... The line under the h hump is the transistor turning on.

notice that the transistor turns on right at the inflection point of the sine wave... Right at the point that it goes negative... the point that the magnet reaches Top dead center and starts to move away from the coil.

Is this old news? or something of interest? Probably something stated a bit differently.

Let me know your views, thanks.

Hi Binzer,

How do you hook up the scope to see a sine wave?

Cheers,

Sine Wave Bedini SSG Motor

I hook up the scope to one of the windings of the coil... it can be the trigger winding or the energized winding (both of these windings produce the same voltage as they are 1:1 magnetically coupled).

Allow the motor to ramp up to maximum speed and observe the H wave on the scope. Now once you see a good H wave disconnect the source battery (you can keep the charge battery connected). With no power to the Bedini SSG the spinning motor produces electricity (magnets passing by a coil produce electricity ... basically the motor is a generator when the rotor is turning).

To observe the H wave in sink with the Sine wave you have to play with your trigger point on the scope. I was easily able to do it with the h wave upside down (basically just switching the leads of the scope on the coil) and using the negative slope trigger and moving wave to part of the H wave hump. Then when I turned on and off the motor the crest of the sine wave lined up exactly with the crest of the H wave.

But then I got playing around with the scope and I figured how to do it with the H wave in the upright position.

But what is interesting about this is that you can see that the magnets passing the coil simply produces about a plus 5 volt to a neg 5 volt sine wave. The trigger coil simply sends a pulse to the transistor to the energize the main coil at the time that the magnet is right in line with the coil and moving away. This whole action was nicely described in a previous post that I saw, and also on a You Tube demonstration YouTube - Inductor In Trigger Circuit.

All I am bringing to the table is that with the motor turned off the SSG is a simple Generator. If you look at the you tube above it is very very informative and absolutely amazing to understanding it all. I really liked to see the sine wave though to now complete my understanding of the motor (to this point )

Just curious

Last night I thought I would hook up my scope to the 80' of coax cable I had up on the trees, and to real ground ( a 4ft of copper wire buired in the ground. I am getting wierd shots.

The scope is reporting a wave in about 60V in size each segment is at 20V, and one Milla second... when I measuer the voltage with a multi meter I get .4 V

( see attached )

Hey theremart,
Just wondering if you have tried anything else with that.
Pulsing it, different caps or coils in between.. etc..
It would be interesting to hear.
Thanks,
Marcel

Please may I request a scope shot or two from a half bipolar circuit if anyone has them lying around Perhaps with a few basic specs from the machine they were taken from. eg, solenoid or window coils, etc...

Thanks!

RE: have I done anymore..

Hi Marcel...

I have switched to working on bigger projects. If I was to try this again, I would use different wire. I believe because of the shielding on the coax it did not give me what I needed. Other factors include that you should not have the wire touching the tree better to have pvc or something to keep it away from the tree some use rope.

I tried caps, the best voltage I got was hooking up to the copper pipes. ( I had an old trailer before 1967...)

Old carbon filters work great for ground as I found from Pirate. I used a couple old Burkey filters I had and they did a great job of giving more voltage, went up to 1.15 V for an earth battery.

But the type of wire you use is a major factor from what I can see. Would be interesting to know about the early wire manufacture what it was made of...


Anyhow back to my Jean pain, Solar cells, and now a windmill playgroud

Scope shot across diode going to charging battery on a standard SSG setup. System running on 31.5 volts@600ma charging a dead 12v 60ah lead acid car battery. Battery currently at 12.76v. Transistor is cold and coil is very slightly warm. Does this waveform look ok?

[Zooty]

Another scope shot across the diode. This time the diode is connected to a third wind on the same coil form and the other end of that coil is connected to the charge battery. The input has dropped to 500ma, rpm's are the same but look at the voltage.

That is two stage inductance

Your first scope shot looks fine.

What has happened in the second scope shot is that now you have increased the number of turns on the recovery coil it is acting as a generator, clipping the sine wave off at the top. So you are converting some of the mechanical back to electrical.

Also, because two stage inductance increases the duration of the flyback, you can lower the duty cycle more than a standard set up, which lowers your amp draw without effecting mechanical output.

Is it possible you could explain what happens in the system during the h wave.. what each part of the wave means?

I think I did somewhere... can't remember which post... let me see if I can find it...

Does this help?
