Bedini Solid State Oscillators

[Chip Shorter]

theremart- I think the SCR he wants you to use should be rated for 800 volts. I have some that are as big as a hockey puck and others that are in a TO-220 package size. All 800 volts.

If your talking about the resistors on the 555 and the h11d1 1/8 watt will do. I would go 1/4 or half watt on the transistor circuit. The cap I used on my first one was out of a flash circuit for a disposable camera. The value escapes me at this time but the whole thing worked great.

How many amps is your SCR? I see them from 18 to 200 amp..

Thanks again for the input!

Thank you, Ashtweth. Where is this old board, is it still alive? Maybe I could read some useful discussions there.

Its a mcr265-10 which is rated for 55 amps @800 on my original version(edit)
Depending on the size of your capacitor. If you use a very big cap maybe you want to go with the higher current SCR. So if you see yourself down the road going to change the cap around or add more, maybe a bigger SCR would be advantagous. Go with what you can afford.
A note about making changes to these circuits: Sometimes when you get the thing running you see what is really happening... In the book Free Energy Generation they talk about getting 300KW pulses on the negative side of the battery... In the same book they show an antenna variation whereas they hook up a long antenna to the HV cap and then fire the SCR into the Battery. If using an antenna we could presume that the voltage is there perhaps 200-600 volts but I can tell you very little current is present perhaps micro amps and the cap is very small probably a few hundred pico-farads. However the Dialectric strength of these componets must be able to withstand hundreds of volts. Also I can tell you that the advanced motor circuit with the 555 charges way faster than the antenna system. So pulse potential/frequency is key here. Remember when discharging caps electron current shows up due to the fact you have a voltage drop when the SCR fires. If you haven't already got the book Free Energy Generation Circuits and Schematics by John Bedini and Tom Bearden it is worth getting. Its hard to read at first but once you build the circuits-the motor ones at least-by the 5th or 6th time you read it all makes perfect sense. I strongly recommend the book because it covers the theory and how it has been misinterpeted/overlooked over the last 100+ years. Also the bibliography section of the book is chock full of interesting info too.

Thanks I have the book. I don't relate to much of it. My objective is to get to supercharged batteries. I hear rumours they exists... but still tracking them down.

thanks

Opto connections

Don't forget what has been previously mentioned in this thread (but 8 months ago now):

The transistor part number in the book is wrong and should be BD243C, another mistake is pin 4 and 5 of the opto, the connections are inverted.

Those opto connections threw me off for a while. Find the H11D1 datasheet if you are not sure. You want it to make a Darlington configuration.

waveforms?

Ash,

John Bedini mentioned on the Bedini_SG board quote that the waveforms in question were correct. I looked on that board but could not find those pics. What waveforms should we be looking for?

Questions from a friend... about the SS building it.

A friend of mine is building the SS. Here is their questions...

"
Hey chief,
I thought of a question, maybe a few.
The solid state charger that you built, did you get it going as it is supposed to from the book?
I have the parts now, from the store today, and I'll start putting the correct version together tonight.
What I was wondering is, I was under the assumption both transistors were NPN, which I'm pretty sure both symbols on the schematic posted for me show it that way.
But the secondary on the discharge portion..
Well, I went to get one at the parts store today, they didn't have it, but had a replacement for it, which was a P based.
Is that one supposed to be a PNP? The one controlling the SRC?
And two other questions if you don't mind..
Did you see a big difference in charging from the SCR section, verses right off the coil?
I had put this circuit together, minus the SCR, with a mosfet, and I didn't see any difference. I'm sure I need the SCR.. lol
And last, if you know, what is the difference between an SCR and a thyristor?
As far as I can tell they are the same thing, but different qualities somehow, not really understanding it.
Appreciate your time."

Hi all,

Has anyone got a scan of the schematic you are all refering to. I havn't seen one yet. (sorry if it is here and i just missed it).

I managed to get my ssg circuit to oscillate by placing a mulitmeter over the 100ohm base resistor. The meter is on the 200ohm test setting. I can get the coil up to 22KHz if I adjust the pot all the way up, but I'm not sure if the highest frequency is the most efficient frequency.

Pics are on the SSG thread. (wasn't sure where to put them.)

[InTheField]

Answer what I can...

I also haven't seen the schematic, but would really like to...

A lot of folks use the terms interchangeably, but the term "thyristor" actually encompasses more than just SCRs. An SCR is a sub-type of thyristor... other sub-types include things like "diacs" and "triacs". (A "diac" is basically a diode for AC circuits. A "triac" is also bidirectional, but has an "on" gate.) An SCR is basically a PNP coupled with an NPN together in one setup. Once it's turned "on", it stays on until the current flow drops below a certain amount. So, when you go to the local electronics store be specific and ask for an SCR. If you ask for a "thyristor" and you get the wrong clerk, you may end up with a triac... which isn't what you want, but fits what you asked for!

take care...

Thank you for the info I have passed it on!

schematic

The solid state oscillator schematic referred to here is in Tom Bearden's book Free Energy Generation. I'm not sure a scan would be legal.

Go back to post #7 in this thread (here). That circuit is essentially the same thing.

RE: scan from book..

The solid state oscillator schematic referred to here is in Tom Bearden's book Free Energy Generation. I'm not sure a scan would be legal.

No, I got chewed out by Rick for posting it on the Bedini III group for a user who owned the book with the corrected schematic. ( part of the reason I left there ) so no, not a good idea to post that schematic... which I understand why... if you can get it for free why buy the book?

But do note the schematic does need to be corrected as stated before, I am waiting till all my parts get here, I hope I ordered the right parts.

So frustrating trying to replicate, when the target moves. But so good to have a group here that help you to the next step.

[dambit]

well how about someone draw up the corrected one. it's not in the book. technically not the same schematic.

What's are differences between the schematic in post #7 and the proper one? Components wise.

(P.S please don't start quoting copyright law, I was having laugh.)
