Bedini Solid State Oscillators

[sucahyo]

no, unfortunately not...and i donīt know yet how to either...

I check the 555 by using it to lit a bulb (replacing the coil). Replacing the capacitor with 20uF or so would slow the oscillation and allow us to see the light pulasting if the 555 is working. Don't forget to add resistor in between transistor base adn 555 output.

Dave,

Put a led in series with a 330ohm resistor between terminal 1 of the H11D1 and the ground terminal 1 of the 555. You can also use a 2N3440 instead of the 2N3584.

Hello All!
thanks a lot for your all your help!

i will have to get the proper caps first. in the original schematic it does show polarized ones.
so for now i left the 555 timer thing and scr etc. out and go 3rd winding - cap - fwbr -diode/neon which i needed to try anyway (itīs my first trifilar coil). WOW works a charm. so now i just hooked up a little solar panel as input and my 7Ah batt at the back and itīs charging beautifully...
i think iīll leave the timer circuit for sometimes later.

Stunning stuff everyone, massive thanks again for documenting all experiments, so, so helpfull.
Got some 6v 2.4ah and 12v 1.2ah doing stunningly well after only 6 charges from 9v 100ma input, only 60 to 80ma actually getting to the batt.

Can batteriesalso get conditioned when on the input side?
Is there any advantage to using a psu input over a battery

Awesome doc you put together there smw1998a, really enjoyed the read last night, gave me sweet dreams indeed. Grabbed some 7555 chips today although they read ts555, any good?
Although, if bridge of the h wave is my base voltage, my scope must be way off. So much for all my data records

If a self oscillating ssg isn't realeasing all it's energy each collapse, could this read higher than the ssg input voltage?

Thank you.

Hi all, very interesting thread, I have put together the astable part of the pulse generator circuit linked by smw1998a, I actually found that PDF about 3 months ago in a google search, the astable part was easy to find the parts from what I have around but I am having trouble finding the 330pf and 470pf polypropylene capacitors for the monostable part, I may have to drive to town to order them I guess (long way), I am in Australia and can order online but I am having trouble finding where to buy them.

Any idea's where to look ?

I'm very keen to try this, many sad batteries here.

Cheers

ceramic caps

Also, are ceramic caps ok, I was just presuming it's ok.

[Farmhand]

Slinky, I went ahead and used ceramic caps and it seems to be working spot, on at 200Hz I have a duty cycle of 0.1% thats 200 x 5us isnt it ? is 5 uS .0005 seconds, I hope so I'm not very schooled up on these things.

Actually I'm not sure if the caps I used are ceramics they are very small and shiny yellow one is marked 471 the other 331. I'll edit with a pic later I have a busy day today.

PS. Here is what I have so far of the circuit in the PDF (the astable part) on a breadboard-http://u7beag.bay.livefilestore.com/...001.JPG?psid=1

I tested it and it works perfectly.

You may want to post in the thread that is created for this, Search for OTG Pulse Geneartor
should do the trick, I have built one as well, works now.

[Slinky]

No problem, you are correct.

Is the arch of my h wave my base voltage? Or could this be much higher if the charge isn't fully released each cycle?

[Slinky]

So where to get answers to the relevant questions for this thread?

I guess the basic stuff just isn't interesting anymore for the more experienced builder.

Can batteries also get conditioned when on the input side?

Is there any advantage/disadvantage to using a psu input over a battery apart from the obvious act of changing the battery?

If a self oscillating ssg isn't releasing all it's energy each collapse, could this read higher than the ssg input voltage?

Is the arch of my h wave supposed to be the base voltage of my input or could it be higher if my coil doesn't release all it's charge each cycle?

It would be a great help if anyone could take the time to answer.

Hi all, I finally got the time to put together this circuit-
It was posted back on page12 of this thread.

Seems to be working great, my coil is only small but with a steel rod "bedini style core" I get 520 Hz and with no core I get 2.7 Khz, input is around 220 - 240 Ma. It's charging up 7 ah batteries likety split. Transistor is a mje3055t and it runs from a 12 volt battery.

Here is the waveform -


And here is the setup barebones can't wait to get it all boxed up.


Awesome thread this but very long, lots of posts to go through.

Hi all,

I'm new to the board and I've been trying to get the page 46 circuit from John Bedini's FEG book to work, but I've run into a couple of problems.

First, I had the SSG working quite well from the Monopole group and I read someplace here that winding a THIRD coil, wound on top of the other two (not trifilar with them) would work just fine. Well, I don't know if it does or not.

I DO get over 200volts from the new 3rd coil, while charging the electrolytic cap that straddles the full wave bridge diodes, so I *think* that coil is OK, but I'm not getting pulsing to the output.

I've read through (PHEW!) most of this thread, and I naturally corrected the BD243C type transistor error and the pins 4/5 mixup on the optoisolator, and I've replaced most of the IC's at least once, to check that they hadn't blown out, but I can't seem to figure out why there's no pulsing at the output.

Should I be getting a square wave output across pins 3 and 1 on the 555 timer?

I'm using all the correct part numbers for the IC's and I'm pretty close on the cap and the resistor values. Any ideas about how to troubleshoot my lack of output? I'm drawing a blank.

Thanks!

@ Farmhand.. I built that circuit a couple of weeks ago. Lately I put 50K pot in place of the 18K resistor. I charged up a cap rather fast. I think my next trick is to put a tri- filer coil and add a scr Pulse with a neon trigger. After that I want to go multi- filer.

[Farmhand]

50K pot in place of the 18K resistor

G'day Chip Shorter, I actually used a 20 k resistor there because I didn't have an 18 k, seems to work well with that.

What have you found the best resistance value on the pot for your setup ?
I was wanting to experiment with some different resistance values as well.

It's a very simple circuit that seems to work very well, I also want to up-size to a much larger coil so it can be used on larger batteries, with a better transistor too.

Hi all! This is my first post, but i'm familiar with this forum for about two years now.
I just built the Bedini SS device and i'm charging a battery right now with it. I used the same resistor and capacitor values as in the FEG book on page 46. The device uses about 260 to 290mA DC when charging a battery and the output is about 100mA. When the output is not connected, i get 367V pulses on it and the input current rises. If i connect a 220V 20W lightbulb on the output i can see the pulses.

Now i was wondering how big batteries will it charge, 'cause now i'm charging a 44Ah 12v car battery and it seems to go almost nowhere. I'm assuming that it will take 3 to 5 days to charge it, will tell you when it's done.

The transistors and the SRC stay cool all the time, so i think that this circuit can be made to charge atleast twice as fast as it does now (the output could be two to three times higher - up to 1000V). Did anybody tried to improve the circuit that way - would a bigger coil have that effect?

I just hope to find some answers here.
Thx for all the info in this thread!
