I'm uploading a different codec (xvid) compression version of that last "scoping the line" video, Stefan, by your suggestion .... twice as large filesize, estimated 40 minutes for the upload or longer.... I hope it's worth it in quality. If it is, I'll use that from now on unless I'm in a hurry.

@TinselKoala

Where Stefan did suggest it?
I will give you a good tool for compression vidos for youtube and this is handbrake , it make high compression with nearly no loss and youtube do not change it. Sincerely

Hi TinselKoala,

Your above idea reminds me a circuit from Jean-Michel Cour where his goal was to discharge a puffer cap into a battery at determined voltage levels of the puffer cap, see here: http://www.google.com/patents/US20070222411  (he got the patent on it too: US 7928700)

I think you can change that circuit to your exact needs. The patent text includes the complete operation with component values

Gyula

I forgot to thank you for this. Yes....  ironically the top part of the Drawing Page 2 depicts just exactly what I had in mind, using an op amp as comparator switching a mosfet... I'm going to have to think about the rest of the circuit to understand it. Thanks again!

In a comment on the video. Thanks, I've heard of handbrake, I'll install it and try it right away.

ETA: Ok, with Handbrake to the default settings it makes a filesize of about 177 MB in .m4v format. It looks perhaps slightly better in fullscreen here on the computer directly than the Xvid conversion by WinFF at 108 MB.  I have uploaded the WinFF version to YT, and I'll upload the Handbrake version after a while. I haven't watched the YT version yet but I'm sure it's got to be a lot better than my first version.

Thank you both for the suggestions!

Holy crap . I am up 6:18 and that little circuit is putting out over 1.535  Instantaneously and the light got brighter  and it is setting 1.466  On a Nicad ? Man . Chills// and yea it is 21 degrees F  outside . everything is froze ,even my flags . Crystal clear and the moon looks like the sun . Beautiful day for light and playing with circuits inside.

I hope this battery don;t short out like My skinless battery did . It also rised and now i know a night of running will carry a cell over 1.5 volts . Old batteries just die especially Nicads if the over charge . But anyways i am getting Great results . Moray ? I need to mount this stuff . It is sitting in a plastic box soldered . My box is way to big so i will wait when i have a smaller one i think .

Stephan , Yes resistors are a nono  in this circuit as they kill whatever is happening . Running from a CAp/Nicad this circuit has exceeded any previously project . It is repeatable guys . Just do it and you will see. It may work with a 12 volt system . I don;t know and won;t find out as i need my transistors so i willl stay at single cell for now . I can do pretty much anything anyone can with an aa powered unit . The lS3 runs real Power from a C cell and i have a video there to prove that  I Am not good anymore making videos with Movie maker . It takes too much time ..but i can do it later on after someone else makes this . I replicated it so it is doable for others to try . This is a real Charge not static . I just tested the battery with a different meter and loaded it is a solid 1.310  . this would be close to an 8 hour charge on my 110 volt battery charger . All the nicads i have settle below this over night . plus this battery was just laying around for awhile and it was on it's way to 1.1 volts .. I am dizzy with prospects of integrating this fix in My Pocketpower+

hoptoad . yes sir i put t5he decimal in the wrong place . Running a nicad here and it is more than exciting to see this happening  . The circuit likes to be left alone and i don't know even if it can be scoped . Every thing external on the circuit changes it . leads act like antennas and change the output . I think it needs a special apparatus to inductively couple any leads without actually touching it . Any suggestions  as to what that might be?

Well getting coffee in me . I tried a germanium and darlington last night on a small coil i wound on a small ferrite rod about an inch and could not get the basic crossover to work so i an working on that trying different transistors i have .. The MpSa14 is a straight darlington and i wold have thought it would work for the primary exciter .. testing ..

Drafted Schematic by -Jesus. Thank you Jesus you are Great!

I have got a new tiny coil i made lighting a green led running on caps . there is a balance , it uses the same setup as before except NO battery . I am using a new transistor setup with  germanium transistor2n1605 with a darlington(mpsa14 as the primary transistor and 1000uf cap and one tiny super cap 1farad .the circiut is charged to 1.5 volts . it is holding up @ 1.65 so far the cap before the second diode is almost exactly the same as before where this circuit begins to charge itself . More experimenting and experimenters should look into this . I am overwhelmed at what i am seeing . I can't begin to explain it . No ground no antenna. the only antenna might be the wire but it's short wire. this is My third replication running.  I need some more good led bulbs like i use in the first circuit. I have to put a resistor in series with  the green clear led to make the circuit work . Once started the led lights and the feedback circuit goes to work .

Edit : it's 10 am and this little tiny coil blew white leds in series . I touched the circuit across the leds and they lit super bright shorting them out . New set on there . this darlington seems to work nice down to about .96 volts . This is where it blew leds. I ditched the green for a brighter lights . amazing me. I also have a resistor sub box and the leds need resistance to get that "balance" and light More later ...

uploading a short clip of my 3rd self charging selfrunning circuit posted . I made this coil last night from a piece of ferrite rod from a computer power supply . I just put one layer of #36 fine tesla wire as the secondary(a drop of super glue to hold the first few turns and the last turn) then used # 26 bell wire 11 turns with a remainder of 4 more wraps to play with . ended up 15 turn primary .. it appears any coil will work as this is My third replication and all three are self charging . the difference in this one is it is running on caps and charging them running two white leds. I love tiny circuits that work especially one that can blow an led in a instant off 1 volt . I will let this one run while i go to the store ..
