Selfrunning cold electricity circuit from Dr.Stiffler

@ Loki
Have you looked at my site or the pictures I sent you direct. The container I use can be picked up in almost any cooking or housewares store for around $9. You paint the bottom a flat black, drill a couple of holes in the top and wrap the thing in insulation.

You are making it far to difficult for yourself, the SS container works fine when calibrated, has a plastic top, easy to work with, maybe your wife is storing coffee in one you can take.

Indeed. I'm not sure of the pictures you are talking about but no worries now.  Will be taking care of this business shortly.

no. I charged so far using 13watts of power from 12.30v to 12.46v. So I believe it will take less than 40watts to fully charge the battery to 12.65v and about 30 to 40 hours max. It is right now charging.

Usually when I do that with my SSG with 6 coils, it takes about 20 hours and 100watts of power to charge it fully to 12.65v.

I also already charged this 100Ah battery once and tested a load to see if it is really a good charge, real power and it is. Now I changed my SEC a little bit more to charge it faster.

This week I will know for sure if it will work better than well. I hope is OU too, cross fingers.

@Dr.Stiffer
Thanks for the tip. I already tested with so many transistor types and the best were MPSA06 and the PN2222 GP. Now with a bigger hit sink it seams to stand well the 20v and 130ma input power. I want to go to 24volts.

I also noticed the ground connection makes a HUGE difference in the amount of power that goes to the battery. I used some extra AV plugs and LEDS to get to the best charging signal. I am also able to run a little motor that serves as a good "measuring rod" concerning the kind of signal the SEC is generating. If it spins faster it also charges the battery faster but not necessarily sends more current to the battery. Right now only 60ma goes to the positive terminal of the battery and it does not even warm up a one ohm resistor which proves it is really small current going in (those are tricks from the Bedini Monopole SSG forum).

What is interesting too is that as I increase the input voltage the speed that it charges the battery is not linear, higher input voltage, much higher charging (kind of like exponential or progressive).

I also tried two SEC together but no luck, they all see each other and interfere substantially the outcome. I thought if one charges, what about 10, would it be 10x faster??? Do you know how to decouple them so that I could use 10 SECs together?

Fausto.

@Dr.S
I usually work with TTL level stuff not used to high frequency high voltage certainly not used to cold electricity or scalar stuff! So a quick question about the SEC boards; is it safe to stick a 10x probe anywhere on the board or do I run the risk of zapping my scope (1Mohm 15pF <=400v)? I have a nice 100x probe on order which should definitely be safe right?

@Loki
I'm impressed with that array of 6x1W LEDs you're lighting up there. Out of interest, to get a similar luminosity, how much DC power would you have to feed them? Probably much more than 139mW I'm sure. Probably more than 139mW even if you fed them low markspace ratio PWM at high freq, SEC looks like a very interesting circuit for sure. Wish I had the parts in stock, to proto it, can't wait for Dr.S's boards to arrive!

@Yucca
I won't say it will not hurt your scope because all I can base it on is my work and so far have not damaged any of my scopes, but I have damaged DVM's. Using less than a 100:1 most likely will not show you a true picture of what is present as it will change the exciter operating point. Be safe and wait for you 100x probe and then you should also see the real form without pulling the operating point.

Well as of today all currently ordered boards are in transient so your should be in route.

@Fausto
If I could decouple them we would all have stable self runners. No matter how long the delay line if the end is returned to ground or back to the exciter it all dies. I have used lines up to 25 chokes long and the same effect. I have missed something big that is causing me many sleepless nights. The power is there, but can not use it unless the load remains floating.

Even with this current problem the SEC15-30W will make enough Heat to be a workable and usable device.

@Yucca,
The LED show, it is cool, literally. You talked me into it and I'm going to do that and see.  Lets take a comparative snapshot here. What is a fair comparison, 5 diodes in series, seems to me would be a "close" and I use that term lightly, approximation of the AV plug??? Since I don't have a luminosity meter presently this is going to be an ugly and subjective comparative study.

The Series string, call it branch 1, will consist of:

VCC feeding,
1. 1N4148 diode
2. ASMT-MB00-NAE00 1W High Power LED, Blue
3. ASMT-MB00-NAE00 1W High Power LED, Blue
4. ASMT-MB00-NAE00 1W High Power LED, Blue
5. 1N4148 diode
Terminated at GND

At the junction of #1 cathode and #2 anode from above the next Series string, call it branch 2, will consist of the following in parallel with 2 through 5 to GND:

6. 1N4148 diode
7. ASMT-MG00-NGJ00 1W High Power LED, Green
8. ASMT-MG00-NGJ00 1W High Power LED, Green
9. ASMT-MG00-NGJ00 1W High Power LED, Green
10. 1N4148 diode
Terminated at GND

Just open the AV plugs at the cathode of the second 1N4148 and tie them to ground. I'll feed this with a DC supply and monitor power input with the same Flukes I always use. 1 reading current and the other voltage. If that description isn't clear I'll post the diagram and results tomorrow. Take a peek at the data sheets for both the 1N4148's and the High Power LED's (Avago Technologies) If I find the need to do some current limiting I will take the liberty of doing so but the diagram will accurately reflect the circuit measured. We'll know within a day or so.  If I were putting this circuit together for a job I'd be planning on more than 139mw that's for sure. 

Best regards,

Jim
