Selfrunning cold electricity circuit from Dr.Stiffler

This is starting to look like people playing with the OU.COM people now.  Would not be the first time.

But thank god we aren't being sent on unexpected business trips...

Dear All,

   I dont know what is going on with my posts, anyway I am in the airport HSBC lounge, my trip is already planned dont worry about it. I was tracked by CIA when I was living Boston.. But why now again? Any way..

   My posts those are asking for using air core rather than BaFe are wiped off???

   Please dont worry for me guys I am safe..

   Regards, have a good night...

Hi All.
I have just ripped apart my old AM radio and recovered the ferrite coil from it.
Now I am seeing also the neon bulb to light up. Still have to build the new oscillator. More soon.
Regards, Stefan.

Hi all,

Look at pix attached.  1 led in series with the input, 10 LEDs on the output. Input and output single wire.  Oh, I live in a reinforced concrete building and I am in the middle of it.  FM or AM radio just don't work where my mini shop is (Worlds smallest lab). I have been through about 100 variations in the last hour and half, learning as I go. My Sig generator is 27V pp output floating as I have removed the ground connector on plug but of course there is inductive coupling to ground but all is floating right now.

Thank you Dr. Stiffler,

I understand about the follower to keep the Osc. isolated and provide drive downstream.  You been around the block a few times!.....most excellent.

Also, I have seen lots of those little 12VDC trickle charger Solar panels and as you say, they are junk!.  I have 3 big Siemens 50 W panels on my sailboat.  Now if we could light about 10K LED's, may have something!  Again as you have noted, output is so subjective on LED's unless you put a meter in there, it is a WAG.  As you say, a lot to try down the line...........so many experiments, so little time!

I'm still messing around.  Tried a full wave bridge driven by both ends of the secondary and manage to get about 12 ma out @ around 18 volts across 10 LED's...haven't followed it very far.  Just trying things now to get a feel for what I am working with.  I'm working on comparative innies and outties,  gives you something to think about.  I'm going to try and get a spark gap Wimshurst RF osc. working tonight and drive this thing! Stability will be a bitch. Wonder If I can get it to convert the very HV RF down to a usable voltage and current in your circuit!  Just something else to mess with.

Keep at it, man your post are most excellent and I look for each one as I learn something from them all.

The solar cell, well I have been trying to keep my web site in sync and it is close, but still catching up. That first solar cell is a JOKE and I told the manufacture as much. In full sun the TOY could only generate 30mA. I do have the start of the info on my site at the bottom of the page. In short, to make it work you will need the best cell you can get, I will give examples and you will need to play with some small mirrors to use all the light, but that is later right?  You Bet!

I may stand corrected, but connecting both of the secondaries to a bridge should remove all chance of any amplification.

You just may have hit on something I have not thought of, with your LED in the input, try two with a 1 ohm in between. Try measuring across the resistor as the impedance is lower this way. I did a similar approach with 20 LEDS split with resistor in between. That allowed some confidence in the measurement. Would be interested in the result. If your scope is grounded it of course will not work. An associate used an ac isolation xformer and did a fair job on readings, buy there is still the capacity. Anyway take the worst case, because you know it is really better.

I put the model number of my solar cells on my site. Beware they are expensive as they are commercial.
