Hi Mart, if your draw is 1/4A or less you should be fine without heat sinks. The 1/2w resistors get a little warm but the transistors seem fine.

Thank you for your information. I am getting closer to having this built still lacking a capacitor that I missed but getting there.

Whew..... a BIG THANKS to all who have helped give me advice on how to get this up and running.

If I am reading my scope correctly I am getting 200V spikes from 12V.

Have not started to tune this yet, ( I have put in two pots ) but I hope to put this threw some trial runs... Looking forward to hooking this up to my 15 W solar panel.....

The devisions were set to 10

Ok,

I noticed that my charging battery was not climbing at all.... So I double check my circuit, and I found I had missed some things on the 555 timer. After a few hours of testing it now is humming right along. At last I am seeing some very impressing rise on my target battery, and for very very low amounts of current draw.

I am wondering if I was to put a load on the battery if it would hold a load as well as if I had charged it with the SSG......


I have been along time about this, and at last it is nice not to have to spin a wheel.

Hi Mart,


I think you're going to like the SS better than the SSG .It will hold a load very well.Nice to see you making progress and let us know how it performs.

It is so nice not to fight with the balance of the wheel, the magnets.....

Simply flip it on and watch the show...

Last night I ran it all night..


Primary battery went from 12.40 to 12.22

Target battery went from 13.20 to 13.75.

I will have to do load tests to see if the numbers are not just surface charge ( this was the case the last time I charged with solid state ....

Hey theremart,
Congrats on the build, sounds like you got it.
I'm still fighting with mine a little, I think it's just my parts, and my breadboards I'm using have had too many things melt down in them.
I had my ss working for one night properly, and it was charging faster than this 8 transistor deal I had built, which I thought was pretty beefed up.
I could hear the ss switching with the cap and everything, it was beautiful. But I did something and the sound stopped, and the charging dropped, and I think I just need to start over and nix the breadboard.
But thanks for the help you had given me, and again, congrats.

The only problem now is I want another one

And I want to convert my 6 transistor Monopole to a 6 transistor Solid State Bedini

I hate the smell of smoke!!! sorry to hear you are having such trouble.

But my SS is charing its little heart out. I have come to the point that I hate to touch it because I might do my smoke signals


I have done a new video showing the results...

Nice video.
I think I have too many projects going on.. lol
The whole scientific documention thing has evaded just about everything I have been working on, just too much in my head I guess.
My to do list still has "SSG load tests" on it, from my first wheel.
Everything went well, so I was invited to the other groups, but my calcuations were a but funny, so I wanted, and still should, do another basic setup, just to get the math down.
Inspiring, good stuff, keep it up.

Marcel

Thanks!

I let my computer log the data... Too painful to keep doing the logging every hour...

Well I put an analog meter on and found I am pulling 100 mA at 12V. Target battery of a deep cycle has climbed up from 10V to 12.3V

I am wondering how to increase the amp pull as I have golf cart batteries and I really don't want to wait 1 week to charge them....

Mart

Well done Mart,

Seem you have very good result....
I can't wait your other test with big capacity battery...

Are you check the COP too?

I found these nice toroidal transformers that have dual primarys and dual secondaries all separately issolated. the primaries are for 115vac and can be hooked in series for 220 etc. Well its a toriod with 4 windings on it. seems like it could be used to make a nice toroidal SS. without having to wind one up by hand.

Search Results Page

There is one available tha has the two secandaries of 115 v also but they didn't show it on the site. that would make a toriod with 4 equal windings on it. but one could actuall use the one that has the 60 volt secondaries and hook them in series and then then you would have a toriod with trifilar windings of approx equal length. The biggest one on their site weighs 13.9 pounds and is 6.3 inches in diameter seems like it would make a kick ass powerfull SS or something similar.

After testing the wave forms on the SS, with a scope, I am thinking I killed the H11D1 in circuit, but not sure.

What is giving me fits is when i hook up the according to the book Pin 5 of the h11d1 to Anode of the scr, and Pin 4 to the B of the 2n3584 transistor it does not work which is how the corrected page of the book reads.. If I switch those two it works, but the wave form look wrong. I am not sure if I killed the h11d1 or not.... I have an extra but I don't want to put it in till I know the correct way to hook it up... any suggestions as to the proper routing of these pins?

The first time I hooked this up I was getting a normal transistor fire on the 2n3584, but then again... I don't know what the wave form should look like comming off that transistor...

Hi Mart,

I have ask to Ren about OPTO H11D1.
24 volt cap pulser battery swapper

His explaination very clear to me, and I made tester for the OPTO to see which still good condition or broken.

hello everyone, since I found this forum had been impressed with the quality and amount of research being done by individuals.I have been working with these type systems for 4 years and I am convinced this is the right path here's a link to my DC oscillator I seem to be getting a considerable amount of capacitor charge, I am using trifilar and quadfilar coils and 200V caps and also incorporated these nifty little 80 V neon lights that I found surplus they are automated machine fault/error lights they seem to work better than the NE2's
with respect and I welcome your opinion.

I got the setup working, as it is charging target battery and now pulling .5 Amp so the target battery is climbing fast. ( changed the resistor next to the transistor from 10K to 100 ohm with a pot next to it.)

I took more scope shots from both the primary transistor and the secondary.


It does seem I am getting the staircase wave


thanks for your help selamatg!

Starting voltage

85 amp 12Amp 12Amp Total voltage Change of Total volts
12.5 12.27 12.27 37.04
12.13 12.37 12.37 36.87 -0.17
9.15 12.54 12.54 34.23 -2.64


Yesterday I took the deep cell 85 amp hour battery battery that I had charged up with the solid state and used it to charge back to two 12 amp hour batteries. This was the results. The deep cell did not seem to hold up for very long with the charge that was given it.

The amp draw was .4 Amp from the SS ( have changed my base resistor to 100 ohms ) and I am getting a different wave form, a stair step effect. instead of the normal sharp high pulses I was getting with the 10K resistor in.

The cap keeps a constant 20V in it as it discharges to the target battery.

I tried 24V input to he circuit for a short time yesterday, the voltage on target battery shot up to 13V about immediately. But I backed off after I saw that it was draining my source batteries at a high rate. Source batteries were two 13 amp batteries. went down from 12.60 to 12.13 in about 5 min.

Hi Mart,

The first two photos of your scope look perfect. As the voltage in the cap rises the flyback voltage is increasing until the cap discharges.

But I can't figure out the next two photos looks like there is a second wave form?

and you say the cap keeps a steady 20v? What capacity is it?

Have you done any load tests yet?

I still can't figure out the tuning on my oscillators... output seems to be proportional to input ie. I can't find a "sweet spot" so my cop is staying between 0.79 and 0.81 ... an oscilloscope would be handy Damn you rich people flaunting your fancy oscilloscopes!!!! l
