Bedini Solid State Oscillators

[Sephiroth]

Update on the toroid...

after 24hours amp draw dropped to 80ma
after 36hours amp draw dropped to 60ma
after 48hours amp draw dropped to 50ma

charging was then pretty much at a standstill at 13.12volts... I was using a desktop power suppy with a constant input voltage of 13.9volts...

I thought perhaps when the charging voltage approaches the intput voltage the current will stop, effectivly halting the oscillation.

To test this i then connected two equally charged 7.2ah batteries, one to charge and one to power the oscillator.

Unexpectedly it is performing normally. Input is approx 300ma and charges the secondary battery over 16volts which is way above the input volatge. Amp draw stays steady... don't know what was causing the steady drop in amps during the first test with the power supply.

First impressions are good... appears to be out performing my previous coils dispite it being a pretty lousy toroid!

COP tests still need to be performed, but does anyone have a good link to where I can learn more about the difference between the magnetic flux in a toroid and a solenoid? I can't really get my head around how the magnetic field is behaving...

Sephirot,
Can you post a circuit schematic of your charger?

[Sephiroth]

nothing special except for the coil... Pretty much a standard SSG circuit except I use a capacitor on the trigger side to aid resonance...

[Sephiroth]

Just completed first COP measurement.

COP = 0.7985

Not bad considering I havent tuned it yet

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!!!

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.

[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.

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]

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

[theremart]

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.

Capacitor 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.

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.

[theremart]

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?

Thanks for you info!
