Hi Romero, @all,
I checked my current draw, it goes up when I connect the diode bridge, then I tried to decrease the turns on my secondary, the power output went down, only 3 LEDs lit,  but when I check current draw it decreased when connecting the br-diodes from 1.6ma to 1.5ma is it sufficient to self sustain?

@Hitmal, @blackchisel97  - Is the current draw going up or down when you connect the led bridge back to the battery? It should go down

Romero

@romero
The first and second pic is the amp draw without the bridge of diodes connected and the wave form it produces, pic's 3 and 4 is with the diodes connected. as you can see my amp draw increases :( but I haven't added another coil on the output yet, that might help.

Cheers Hitman

@Hitman
I don't know what to say... I am not sure what is wrong there, the input draw must drop when the bridge is connected to the source.What about when you short the led bridge output terminals?
What is the voltage after the bridge? Try using a variable resistor in series with plus lead connecting the bridge with the battery.

Hi Romero @ All.
My very first circuit built 3 days ago is still running well and I have a small battery gain - 0.002V.
My second one, on 2955/3055 (updated 1st circuit) kept draining battery so I decided to redo it. This time on 2N3904/3906. It will run on 1mA with all LED's dimm but that's not what we're after.
When I connect the bridge to the battery (of the second one) there is a slight increase in mA draw (AC side of the bridge remains connected to the circuit and LED's are lit).
I don't want to "disturb" my first one since it is holding well
I'm still working on it.

Cheers

@blackchisel97
is best not to touch any working one. Many times I get problems replicating my own work too, there are many variables involved and some are not known yet.

@Romero
Yes, I found each toroid even done same way, same wire length brings different results. Unfortunately, those which I have a few (all the same) from power cord filters aren't the best. Same with transistors and even LED's. I need to find variable cap so I don't have to switch them every time.
I've been trying to run from single kHz up to 100+ depending on components.

This nice 1st waveform you have posted before was with second circuit ( two toroids and ground) - am I correct?

Cheers

Romero

@blackchisel97
yes, that waveform came from the second arrangement.

Thank you Romero. I've been trying different inductors and transformers to replicate my first but couldn't get same results (yet). Also, my first one started to drop until only 2 LED's were on. I tried to compare inductance to see if it can be a factor responsible. I didn't solve this one yet. I tried the second schem. but I left it for now until I fully understand how to replicate the first one each time.
Meanwhile I was (still) playing with other circuit which should desulfate the very battery which powers it. It is simple 555 triggering gate of N-channel Fet with 2 coils in series. It can be used to charge another battery via diode off the drain or the diode can go parallel with 2 coils from drain to the positive rail. There is a capacitor between the neg. rail and connection between both inductors.
I can post details if anyone is interested and want to play with it. I also work on electric fence to protect my garden from visitors (racoons +). Again, I can share details (if anyone has similar problem) when I get this done.

Thanks blackchisel97, I'd love to see your schematics.

Hi blackchisel97,
Are you using the same transistor Romero posted? I think it's best or try using different low power transistors, and also try different lengths of winds on secondary, mine I manage to get the amp draw to 1.19ma and it's holding well, it's almost 3weeks and the battery voltage did not drop still 1.25v, I'm working on the second circuit but no succes yet, about your circuit pls post them, and I'm more interested on the electric fence to protect my things from being stolen.  ;D

Happy day! Regards

The leds are more brighter than before..

Hi guys. Crazycut06, your yellow toroid looks like the one from PSU. Very nice result you've got on such low mA. I don't have the same transistors Romeo used. I tried 2N3904/06 instead and 2N222/2N2905 but I only had two of 2905 and used one already in solar levitating Mendocino motor.
My first setup was done on them and works better than others but it started to drop after a week.
I used same type toroid as you have.
Here is the site with electric fence schematics - http://www.pocketmagic.net/?p=2217.
I changed caps from IC pin 5 from 10n to 100n and in the last moment replaced 3055 with N channel FET. I had everything soldered on proto PCB board and just left 2N2222 as per schem. This could be simplified but works perfect and I'm getting over 1/2 inch spark (very painful :o). I don't see a reason for 20 Ohm resistor to be at 2W as everything runs cold even at max frequency. I used 12V ignition coil without internal resistor.
Second circuit I was playing with is from this site - http://bedinimotors.blogspot.ca/2010/06/bedini-ssg-circuit.html  - scroll down the page. One thing puzzles me is that the core of those coils is drawn like two separate coils, not bifilar. I tried both with different cores and wire thickness and I didn't figure out this one yet. I know, this is nothing impressive but I don't have a budget to do what I wish and cannot sit and do nothing at all. Sort of therapy ;D

Hi blackchisel97,
Yes that toroid is from a computer psu, thank for sharing your electric fence circuit, but  i think it will not work for my fence co'z its heavily grounded, its welded through the inside of the beam, any suggestions?

blackchisel97

Hi crazycut06. What about running single wire over the top of your fence, isolated from it? At least it will discourage intruders from climbing over.

Yes, that was my last option, thanks!
