Bedini Solid State Oscillators

Testing out the SS

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.

Ok SS Bedini up and running...

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

Mgc.

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

[MGC]

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.

RE: voltage

Mart,

A 16V capacitor would be fine but 25V a safer bet.


I notice Sephiroth mentioning in a slightly earlier posting about JB using 'high voltage' pulses from a cap pulser to charge batteries. It's more a case of once upon a time he did, more recently he's gone for alot less than this i.e. 1or 2V over the battery.

One thing to remember when playing with JB circuits. Build them as JB says first before seeking to change them.

Thanks for you info!

Heat Syncs

Ok, starting to build the SS, and I am thinking do I need heat syncs on any of the transistors or the scr?

couple volts over batt

The first cap discharges I did were a couple volts over the charging batt and discharged with a mechanical copper switch that I made. That gave the best results I've ever had as far as what I was able to pull out of the charging batts.

Thanks Seph

I understand, I was hoping Aaron or someone else could fill in the details of the cap next to the 555 timer what it's voltage may be.

sorry Mart, can't help on that one as I don't have the book though I have built a few 555 circuits so can have a pretty good guess...

the cap should be at least 12v... probably best to go for around 18-20v. from what I understand, the 555 works by comparing the voltage between the cap and the input voltage. When the cap gets to (i think) two thirds of the input voltage it discharges the capacitor through the output to ground, in this case through the opto and 330ohm resistor, then resets once the cap has discharge.

You can uses the 150k pot instead of the 330ohm resistor closest to the cap to adjust the interval between the pulses as it will vary the time it takes for the cap to fill to the trigger voltage. I don't think the capacity of the cap makes too much difference.

Someone please correct me if I am wrong as my knowledge of 555 circuits is limited

Ok... Starting to get the final parts for my SS Bedini

Most of the parts have come in for my Solid State Bedini.

I have choosen to got with the corrected version of the book page 46 Free Energy Generation.

I do have a question, it states it requires a capacitor for the 555 timer, it says it is a 1 uf.


On another schematic I have they have 2.2uf capactior but they use a 100K pot with the 555 timer...

What I need to know is how many volts this capacitor next to the 555 timer needs to be in the book version. Thanks!

[Sephiroth]

I have built several variation of the SS though not sure if any of them are from the book I do not have alot of cash to spare and I am saving for an oscilloscope so can't afford the book as yet

I am using 22 guage and 26 guage wire

I have tried cap pulsers as well, but as yet have not been able to get as good a cop as just connecting the battery straight to the coil (via diode)...

Also tried trifilar with a recovery coil but unsure whether this is an improvement over bifilar...

However, I was having another look at thedaftman's schematic and I realised the advantage of doubling the turns on the recovery coil; it will allow the battery/cap to charge above the primary voltage with the coil being energised (as opposed to just using the collapsing field). This would justify the bridge recitifer. I think that it may capture more of the collapsing field as well. Worth experimenting with.

Re: Cop

Thanks peper!

0.8 is a pretty good cop to begin with.... I'm sure I can improve it!

Thanks Seph!

I should be getting my parts in next week for the SS. They had some parts on backorder.

So have you built the one that is in the book FEG?

Also what guage of wire did you use? I have 20 guage wire, and I am wondering should I get the exact gauge of wire required?

Thanks.

Congradulation Seph!!!

Nice to see you got results(better then what i expect you can get from it).
You show us once again that you are a well self motivated experimenter!!

I SALUTE YOU WITH ALL my respect!!!
