Rodin Coil Tests and Replications

[stubbs]

Hi all,

I pulled out my PWM and pulsed 40kHz @ 150Hz.
Right off the bat; lit a 25W & a 18W bulb.
To tell you the truth, I am tiered of this bulb thing. Espeacially after those tests...
Tomorrow I will put my 1Gig Functions Genny on a opto as was suggested.
I will then tune it to a 100Ohm 100Watt Resistor, and start charging
Batteries with a swap circuit. The swap circuit is built with 741 OP(s).
Sensing input with three opto. (H11D1) outputs.

I would have posted on this earlier... Buuut....
My 600W Grid Tie inverter Blew @ 375W. "Had a Lemon"
Batteries Charge extremely fast. All my Batteries came out of a junk yard.
I have managed to recover the Batteries in this circuit, so far...

well stubbs i didnt know you had a 1 gig FG , excellent !

btw, which video or whatever..did you use to guide you in winding your Rodin coils? as there are at least a couple of different ways to wind and these differences may well become important in future replications.

had a nice sunny day here so gave my batts a nice refresher for free

if you find time, in your next video or whatever, could you do a quick run-down of your physical configuration of your rodins and associated things.... ie :- which coil is on top etc etc.. connected to..whatever it is connected to..etc?

Many thanks again for your sterling efforts

Hi Rave,

I used Gem's Vid to wind both coils. The only winding difference, is that I pulled
all the windings together. Instead of dividing the space between windings.

My 1Gig FG is dead... ouch!!! But fortunately I had an old one from school.
It is only 9MHz; Oh well... I managed to hit a freq. somewhere around 100-
140KHz @ ~10VDC Gate pulse that lit a 25W Bulb full. Unfortunately the
Transistor blew chunks everywhere. But that was not all; it took about every
Diode with it. I have a new Transistor now. It is a 500W capable block
FA57SA50LC. I am now waiting for some ultra fast 50A 1000V Diodes; ordered
them yesterday.

Daydreaming at the Junk Yard
I was digging around at the locale junk yard and found steel re-enforced Hyd.
hose laying around. I got a crazy idea of making a very fatt and Large in diamiter,
Rodin core. If I design a Magnet lined wheel to rotate through the Rodin core,
I believe that the Bedini SSG would excel; not only creating a charge, but an efficient mechanical drive as well??????

Just a thought

Damn stubbs, how much juice do you have going through that circuit !??!?!

[stubbs]

51 or 52VDC @ ~400mA at the time everything bang.
I can say that the bright light and the Bang were pretty impressive.
Woke the wife out of a dead sleep...

Stubbs,

so around 20 watts or so input.

i am at the moment trying to salvage parts from 4 PC power supplys, got some nice large semi's on there, toroids, caps of course....got a decent'ish 5000uF @ 200V cap bank now :-)

still cant wait to see your schematic so i can start at least in part replicating with what i have here.

going to put together GEM's latest solid state circuit and try it with the rodin which is now completely filled with Fe304(magnetite)...see if theres any difference/s from without it.

keep it up

[stubbs]

Ya i'd say around 20W, but it does not make any sense.
The Transistor is a IRFP450, which is good for over 100W.
My Caps sustained at ~240V w/light. It is possable that I
over shot the diodes in current causing the Transistor die???
Or... The back EMF was too great. (which I doubt, because
of the sustained voltage on the Caps)

I should have the circuit ready to post this weekend.
I believe Gem is onto something with his Rodin Genny.
I have been wanting to replicate the Bedini SSG, for a while now.
But after seeing what Rodin coils are capable of....
A magnet driven by the Rodin coil, switched by B. SSG; provides alot
of torque without losing /compensating the charge effect on i.e Batteries

Just a thought...
Batteries on a couple of battery swap circuits. One for the powering Cells of the Rodin SSG
and the other swaping 2 separate banks between charge or powering a Grid Tie Inverter. (20Hr per Bank)

What do you think???

[rave154]

Stubbs,

I like youre thinking :-)

but i think, without wishing to dampen the enthusisam obviously, lets you & gem & myself kind of get more or less on the same page circuit wise & equipment wise...and then kind of....vear off to the sides a lil... make sense?

in terms of "what" blew your circuit.....honestly.....i wouldnt put anything past being a possibility when it comes to this Rodin coil.


its interesting, and i might be wrong here.....BUT.... im ususally using 12V only in my tests etc...and i havent really observed anything REALLY out of the ordinary......however....GEM & yourself.are using 24V, 36V.....50V.....and you guys seem to be getting the goods..... a voltage threshhold in play here perhaps ( or a current threshold, same thing really ) ??

p.s

when you said " build a large fat rodin.and put a magnet disk in the middle to be able to rotate"... did you mean have the magnet disk in the same plane as the rodin is in.. ie both horizontal......or..... have the magnet disk at right angles to the rodin plane?... i will try and draw what i mean.

[rave154]

attached is my crappy drawing stubbs...

upper left...is the "same planne" arrangement..red is the rodin coil...green is the magnet disk..blue are the mags on the disk..

lower right.. is the "right-angle" arrangement...obviously this would not be possible with a solid disk.. it would have to be a flat toroid disk.. supported somehow so that its entire circumference can rotate through the middle of the rodin coil..along with the magnets attached to it.

[stubbs]

I believe you are right about the voltage amongst other.

At the beginning of this all, 14.1VDC seemed to be pretty efficient
at certain freqs., also at 24VDC and so on... efficiency and effect seem
to increase. Too bad I cannot play at the moment... I wish to replicate
everything I did when I blew the Transistor. With better components of
coarse. At just over 50VDC everything; from what I can tell (in that breif moment)
was quite efficient and seemed easier to tune.

That 25W Bulb was brilliantly lit; as in Gem's Rodin Genny.

[stubbs]

Correct... Need to come up with something as such.
Need to look into that. Motorbikes have evolved to shaft
driven "spokeless rims".
here is a good one...

Coil collapse coil may produce voltage much greater than input. At 12V 500mA my ordinary coil can light up neon bulb which said to only light up at 70V above. It surely more than that at 50V.

You have to utilize the coil collapse current.
from two wire going to the coil, add in parallel a lamp in series with diode blocking source power.

[stubbs]

Hi all,

I finally finished the circuit. It is probably not error free. It has been a while since I have done anything in any E. CAD programs; let alone electronics.

If you see anything wrong; PLEASE!!! let me know. It will help me alot.

T1 was swaped out with a fa57sa50lc.
D3 was swaped out with a stth9012tv

Circuit moved to post #132

The Bedini folks use 1000v diodes because lesser ones get trashed.

ahh....good work stubbs....... digesting it as we speak :-)

any joy using your other sig gen yet?
