Hi Daftman,
Cool circuit, would love to build one can you upload the print off plan so i can have a go? keep up the fantastic work. plus looking forward to your results with this one. the DSSC = Daftman Solid State Charger.
Cheers

I will be doing a downloadable diagram soon but need to complete my tests and do a bit more work on the circuit before publishing it.

I have not yet finished all my tests but the tests I have done look promising for revitalising batteries.
I used the DSSC to rejuvenate one of my drill batteries that was about to be thrown, it’s now back on the drill and as just done a days work and can now be recharged on it’s own charger.
The only thing is my coils were getting hot so need to do more on them. So if anyone is going to give this one a go please be advised, keep a eye on your coil I think more terns or needed probably 1500 if you use thicker gage wire you will need even more turns. Don’t run it without a charge battery connected for to long as it will blow the NB.
This unit pulse’s the mosfet and according to the data sheet it’s capable of a continuous drain current of 40 amp and a pulsed drain current of 230 amp. This circuit isn’t capable of that type of current 3 amp would be pushing it, now with a small amount of modifying it could be used for HHO production (PWM)
This unit was tested with 2 coils wired in series and came from Maplin Electronics 250 ECW 0.71mm 22swg order code YN83E and was used has they came.
I will be doing more on this unit including modifying the diagram to collect the back EMF energy into a capacitor then discharge that stored energy in to the battery for better revitalising.
This unit is designed to run on 12 volt.
This is the link to the new downloadable and printable version of the diagram.
You will need Micro office 97 or above to open and print your copy.

| I appreciate the Set Out Board you have drawn. It makes life easier for the non schematically inclined like me. One question from someone learning about triggering devices with a 555. Is the trigger from the 555 enough to fully turn on the FET? I have seen other similar circuits use a small NPN or PNP triggered by the 555 to turn on a FET do to poor saturation of the gate. |

alien, it depends on the FET and it's saturation voltage... but it's not all about voltage, when a transister or fet actually turns on it draws curent from the base... 555's can only supply a certain amount of curent befor they blow...
So, to help prevent from killing 555's they use an extra transister...

Hi all. Just wondering if anyone else has built this circuit? Thanks to Sir Daftman's very easy to follow diagram, I built the circuit as shown, but could only attain a pulse about every 36 seconds, which corresponds to 555 calculator results for a 1M R1, 50K R2, and 100UF C1. VR1 & VR2 adjustments had no effect. I'm just a hobby level electronics amateur, but after comparing the timing portion of this circuit to other asynchronous 555 circuits, it looked as if the 555 output is feeding back into VR1??? So, after calculating R1 and R2 values, I rewired the 555 conventionally, using two 5K pots for VR1 & VR2, and eliminating R1, R2, and D2. The circuit now oscillates normally and pulses the 26 ohm coil, drawing about .6mA. But the charging battery only fluctuates about .2Volts, and does not rise. There is much that I don't understand yet about back EMF. Maybe we need to use a bifilar wind coil??? I guess I need to study Bedini circuits some more, and experiment. Thanks for your time.

Please post a pic or a video of your build,
I do no of 5 others that have built from the diagram as is, and they are working perfectly so I don’t understand why yours isn’t performing.

Well, normally I would breadboard my tryout circuits, but your diagram was so easy to follow, that I just built it on perfboard and wired on the back, so a picture really wouldn't show the connections. I do like your MDF and brass nail constructions though, and I may try it next time. Anyway, Ive been playing around with some of my shaded pole motor coils. The original one I used was 7 Ohms, which drew .6 mA and would only charge a capacitor to 40 volts. The last coil I tried is 76 Ohms, which draws .2 mA and charges a capacitor to over 200 volts. This one seems to be working much better on my charging battery - voltage is slowly increasing. Wish I would have started these experiments long ago - Have a long way to go to catch up. Thanks for your help.

Hi all. I have not had much luck with this circuit. Charge battery keeps fluctuating +- .2 volts. Any success stories,or advice would be appreciated.

| what kind of batteries are you using bojangle? mine doesnt seem to like NiCd batteries too well. loves solid lead acid batts though. |

TEEP, what is the current status on your DSSC? Do you know of anyone who has modified Bedini battery reclamator to do what your DSSC is doing? Good luck with your endeavors,

Hi Daftman...
I have just completed this circuit and it is working fine. It is as you said, it works like a charm on lead acid batteries and presently I have a 12v battery being revitalised, as it would not accept a charge on a standard charger. I first had a coil that had 450 turns of 23awg, but found that it got rather hot. So I had a spare tri-filiar coil and looped the wires together so that I have one large coil, just like you showed on your movie. This coil doesn't get hot and nor do the ceramic fuses. I also noticed that when the caps charge up and fire the high voltage to the battery that NB flashes for a split second. This seems to repeat itself over a few minutes and I figured this is what it is supposed to do.
The pots I have both set to the middle as I don't know what I am supposed to set them too, maybe when you have some further tests done you may wish to share this info.
I will make some pictures soon and place them along with this message to you and I thank you once again for the great project.

Hello Forum,
Does anyone know what the optimal coil configuration for thedaftman's DSSC? If a trifilar, or bifilar coil is what's needed where can I purchase one in England? A friend of mine is flying to Costa Rica from London and he's bringing parts. Thank you for your help,

Hi Topher. The Daftman's DSSC is just using two enamelled copper wire in rolls of 250g 0.71mm
(22swg)70 meters, in series from www.maplin.co.uk. |

Just came across this video by youtube user valllhalla and thought you all maybe interested.
If the circuit is put together the way it’s set out the only thing going in to the cap that’s running the 240v bulb is the collected BEMF.
I think most of you on Teep that’s seen my videos will probably understand that I don’t believe in BEMF, now with this video I will have to sit up and reavaluate my believes on BEMF as this video seems to prove theirs something in it. So back to the drawing board for me.

miloman, it sounds like you have an error with the flash plugin on your PC. Uninstall flash and then re-install it to see if the error is resolved...

Hi All,
Thanks DaftMan for your wonderful work. You have been an inspiration to me and countless others.
I have just built the solid state charger, which appears on this forum.
It seems to working very well(last hour or so), but when I connect the charging battery, my neon bulb still flashes. After about 1 hour, my source battery has lost close to 1 volt, but my dead 12V 1.3Ah charging battery is at 6V(6.5Ah), from 3.3V.
Does anyone have an idea why the neon still flashes when the charging battery is connected?
I will try and post some photos, if I can do that on this forum.
edit - Here is a picture of my charger : http://photobucket.com/KryptKrunch
Thanks, Krypt |

Does anyone have any experience with winding different coils on the Daftman DSSC and how they perform? I would imagine there is some kind of optimal configuration, although this is likely to be a little dependent on what batteries are in the circuit too. Bifilar, Trifilar, Series wound coils? It would be nice to know of what others have found and if they could supply details like wireguage/length/number of turns and possibly what is the resistance of the coil on a standard ohmmeter.
It is a little expensive to go through so many episodes of coil winding. If anyone can help I'm sure many will be listening. Thanks to The Daftman for providing such great tools and design aids so that many of us can take part in such an important adventure.
