My Motors got me to Tap into Radiant Energy

[iankoglin]

G'Day UFO and all others
I really like to thank you all especially those that helped me to try and debug my machine

Now with Torpex and Larry's input
I made up a single Mosfet circuit and used this to see if the Regulator and then the Oscillator were working (so I would only Smoke 1 Mosfet)
The regulator does work the 555Oscillator does Oscillate but I think it is not sending the proper signal or is not strong enough as it seems to change the frequency along with the duty cycle.

@ Larry
I was originally using Bob's Oscillator and when I was having trouble(Thats me all over) You suggested on page 28 post#111 that you modified this oscillator but as UFO suggested we should keep it simple and use the 555 Oscillator so I continued with it
The others all seem to have success the Bob's updated LM339 Oscillator page35 post #1026 Here

http://www.energeticforum.com/199376-post1026.html

or perhaps Larry I should build the one you have posted on page35 post #1029 the one also showed on page 28 post #111 it is here

http://www.energeticforum.com/199382-post1029.html

@ Torpex I believe you are using 2 double LM? in your circuit

Please I appreciate Your Input

@ John Stone

I recieved today in my mail I think from GlobalSource I thought that it may be of Interest to you Its above my head but this is what you and others have been discussing I

Hi Ian
The main difference between my circuit and Bob's is mine has the complimentary second output.
The FET you linked to is a surface mount and is only rated at 25V instead of 400V and it has 2 FETs built into one device. If you are blowing them at 400V I don't think these will work.
Did you determine what the output of your oscillator was?

Warm Regards
Larry

1.
Shure, here you are:

V2 Generator separated from several possible drivers.

But as i mentioned some posts before prepare your setup to go for opto drivers if possible. You can drive the optos from 12V or 5V generator output adapting the pulup resistor only.

2.
BTW: Today I got 4 identical PC PSUs from scrap (ENERMAX make).
I extracted 8x FETs 900V / 10A ready mounted on heat sink and lots of other components like power shottky diodes on heat sink, opto couplers, 200V electrolitic caps ..... As neat add on - linear voltge regulators like 7805, 7818 .....
So take this as a hint that PC PSUs are a valuable source of switching components being prepared to support our desire for OU.

3. What happened to our friend Ufo? What is the make of his independence day? Lots of more or less harmful accidents possible! Or just a detrimental PC breakdown?

thank you JohnStone
1. i have nothing but seriously basic skills in these fields...i could probably manage to burn myself with my soldering iron if i tried ;-)
so i hope you will draw the opto driver some time and that i can find the FOD3180 or a suitable replacement.
The FOD 3180 are not available where i am. does anyone have some other numbers by which to identify suitable opto-couplers when ordering?
2. thanks i'll openup some psu's and see what i can find.
3. my first guess was underestimation of completion time required and second guess was isp trouble/interferance. very glad to see he's back

The fets I know nothing about I just thought they may be interesting
Thi output from the Regulator is 13.4v into the Oscillator it Oscillates Duty cycle 0.4% to 99.?% but the output varys in volts like 4.?v

as I said I made a single Mosfet circuit to test without the coil it works as far as the regulator but not the Oscillator so I connected the 6 Mosfet Circuit and it works with the regulator but not the Oscillator.

I will try the original Bob/s Oscillator that I made first and see how it works today I was just checking it to see that I wired it OK

...

Again and again: we need to seprate different levels of maturity in our setups. DO NOT MIX THEM!

Level A: Low side driver with N-FET
If you are not experienced with electronics please build your setup with low side driver as posted already and get it running with HER.

Level B: Low & high side driver
The addition of a high side driver is an improvement but no essential asset for basic research.
For low voltages a direct driven P-FET is suitable if available for you - as posted by Ufo.

Level C: Galvanically separated driving

• makes P-FETs obsolete
• it is a very rugged and variable building block
• requires more expertise

C1: optical isolation
Please consider that for an opto separated driving we need more than an opt only:

• opto separation for drive signal (opto coupler)
• driver after opto (FOD3180 or similar drivers contain both items)
• galvanically separated small DC/DC PSU for the driver

Please consider that those members pioneering the galvanically separated driving do not have final sugestions as reliable instructionables yet. This is currently the direct way but requires those special components not being available all over the world. I am so sorry of that.

C2: Inductive driving
There is an alternative for driving -> via small transformers. This is a simpler but most tricky approach. I have no experience with it up to now.
I will try it for you after having success with my opto approach.
Others with experience and willing to pioneer this matter are welcome.
In order to understand the implications see page 30 or But PLEASE do not understand these expert hints as instructable for easy replication. Simplicity has its price! You do not get it for free!
Google search. "fet pulse transformer"


Please find your level of experience and perform it. Ufo tries to get all levels mentioned above with him. Wait for his next disclosure. Focus on him as guide!
@Ufo: Glad you are back and well! Festina lente! (Make haste slowly) . It is not easy to wait but do not haste! Thanks for your effort and contributions. They are very much appreciated.

Don't check your oscillator output with a DMM... only use a scope. The DMM gives you the average (RMS) output and not the amplitude of the signal feeding the FETs base. Changing the duty cycle of the oscillator will change the RMS output of the oscillator, but should not change the amplitude of the signal. You need at least 4V signal amplitude to turn on the FET and your oscillator should be putting out between 10V and 12V amplitude at any frequency or duty cycle. How are you coming up with 0.4% duty cycle? 5% is really hard to see on a scope?

as I said I made a single Mosfet circuit to test without the coil it works as far as the regulator but not the Oscillator so I connected the 6 Mosfet Circuit and it works with the regulator but not the Oscillator.

Exactly what are you saying here? You are getting regulator output (13.4V), but you aren't getting any oscillator output after you attach the FETS? Do you have a coil attached to the FETs?

I will try the original Bob/s Oscillator that I made first and see how it works today I was just checking it to see that I wired it OK

Still working at it

If your oscillator works before you attached the FETs and not after you attach the FETs, it most likely isn't your oscillator, but your FET circuit. You could switch oscillators all day and not fix anything. After you attach the FETs, what dose your oscillator output look like on a scope?
If not oscillating, is it high or low? This will give you a clue as to what the FETs are doing to your oscillator.

Let me know the answers to all questions I asked here... I can't help if I don't know.

To all guys owning no oscilloscope but a PC:
Poor Man's Oscilloscope
Soundcard Scope
41Hz Audio - PC soundcard as a scope / measurement instrument

Googel search:

These progs can be great help for basic watching what is goning on at your oscillators.

In order to protect your PC please use a voltage devider 1:10 between your circuit and the sound input of your PC.

• The sound input is limited to about +- 2.5V AC!
• 20Hz ... 20KHz sine shapeed signals.
• Square about 10Hz .... 5 KHz
• NO DC measurement!
• Never apply HV signals to the PC!

Especially the prog from Zeitnitz is widely used and conatins a signal generator as well.

This is a suggestion for you low funded enthusiasts in order to enable you to overcome serious limitations. We want you to succeed as well!
I did not use these progs myself and can not help but please share your experience in order to help others.

Diodes to protect fets?

Hello everyone!

Thanks JohnStone that reminds me I have a computer to setup for an oscilloscope/workstation. Great guides, that will help me get that computer going while I am waiting for my part orders.

Could you add an extra diode immediately after the mosfets as another option to protect the driver? I found some low loss 600V 11.5A and 1A rectifier diodes. I want to try to use them for for mosfet protection as well as output filtering, what do you think?

Really good specs on the rectifiers that make them look appealing but I'm a noob to this circuitry stuff, so, please be kind.
IDV02S60C 600V 11.5A
CSD01060A 600V 1A

Good to hear back from you, Ufo!

Best wishes,
matt

This should really help those that do not have a scope. I checked out the links and all require paid registrations of from $19 to $49.

You can get a hand held digital scope on Ebay for $79

Here is a free software scope (BIP Oscilloscope). Just basics, but will work for this project and free.
Downloads - BIP Electronics Lab Oscilloscope - 3.0

This can be used to wire up your sound card to work.



Think I will put it on my laptop so I will have a more portable scope.

..

Hi Matt,
where do you intend to add a diode in specific? Where cathode, where Anode?
Where does teh FET live? bottom ? top?
rgds John

@Larry. Thanks for your addon regarding PC scopes. I checekd the sites not thoroughly enough.

[codeboundfuture]

Oops..

I'm sorry John,
My mistake, I was thinking of the circuit as using a P channel mosfet to drive the coil. I have N Mosfets.

Like I said, I'm a circuitry noob.
I didn't mean to waste time.

Best wishes,

Hi All
I set up a photobucket type image host on my website. It is for use by people on this thread only.

You are free to use it if you wish. You will have to register to use it.

Good idea

Hi Larry,
That's a good idea to get a central image repository going.

Maybe we should also start a wiki so we can keep talks about specifics organized?

I like the idea of IRC too for those looking to stay in touch real-time, with the chat kept logged on a page of the wiki so it stays somewhat forum like. All in due time, just some ideas to see how well everyone would participate.

Knowledge is power.

scopes & stuff

Hello all. Been lurking full time for 3 days, starting at page 1, finally up to page 40. Like most of you, spent two of those days hitting the refresh button on page 38-39 every hour or so
Even prior to that I was scoping out scopes. As an old electronic tech/engineer/licensed electrician/ne're do well I feel quite naked without one. I would like to add to this portion of the discussion.
I run Linux, most Linux folks are probably aware there are at least 4 or 5 totally FREE software scopes for Linux. The one I have is xoscope and it appears quite adequate (judging by watching the noise level, as I have never connected a signal, kinda scares me, since I have only the one computer. Although the circuit Larry presents would be just fine for say, checking right at the oscillator output.) I should think there are freeware Windows scopes out there as well, and of course, you could always d/l a Linux Live CD from any of the major distributions and run the Linux versions without even having to load Linux on your HD. You'd have to reinstall the scope on every boot, but not a big deal.
A couple of circuits that would provide a layer of isolation for your computer:
I especially like this idea, because all you gotta do is buy a $1 usb sound card from ebay, voila! if anything happens, buy a new $1 soundcard, computer sound card unscathed (you don't really need the link, that's the whole idea):
usb sound card
Dang! lost the other one. But the $1 USB soundcard idea would win, the other was $5 worth of parts built around a PIC, too much effort for roughly the same device. Of course, you must use a software scope with it.
Finally, I have found Aliexpress to even beat ebay on scopes. It seems to be sort of a Craig's list for China, only new items though. A sales front for them to expose themselves with. It's like DealExtreme on steriods.
$25 USB scope (good to 3khz, probably enough for this stage, but pretty limited)
Nice selection of across-the-board scopes
On the subject of wire for the coil, perhaps the most costly single item of this project (if you don't already have it in the garage), I found that about 200 feet, or 1 pound of 18awg magnet wire is just under 3 ohms. Meaning that two strands twisted up Litz style and connected in parallel would be just under 1.5 ohms, UFOPolitics target number. Here is a link to the cheapest deal I have found so far:
1 Lb. 18awg Enamelled copper wire $16 (buy two, free shipping)
The purchasers of that deal complain because it looks like the wire was wound on the spool by hand, but that shouldn't matter to us, twisting it bifilar & all.
Lastly, I would like to add that I am very impressed by the camaraderie of the entire community here, the excellent work done by so many, and of course, last but by far not least, the superb work & skill of ufopolitics himself. And by that I mean not only his skill in conveying these concepts, not to mention rediscovering them in the first place, but his social skills as well. The deft manner in which he has dealt with the know-it-alls early on has contributed greatly to the ease with which it can all be absorbed. Bravo Sir!
And thanks to all you hard-working replicators too. You play an essential role in convincing us all!

Hi again @All
Finaly I've got my setup with a CLF going after accidental signal generator damage...
Inductive Collapse Lighting a CFL
In this short clip I am lighting a CFL by pulsing a pancake coil and catching the BEMF from inductive collapse of the coil's magnetic field.
There is a secondary winding tuned with a capacitor to form a LC tank circuit to resonate at lower harmonic frequency of the primary (250kHz&50kHz).
On a scope across the tank circuit I see a pretty clean sine wave.
Two batteries supply 24V to the pancake coil through a MOSFET.

I am eagerly waiting for the animations Ufo.
I am into 3D CGI too need some help with rendering? I use NewTek's LightWave 3D
