Rodin Coil Tests and Replications

[geminitric]

Greetings,

I am creating this thread as a place for discussion to focus on Rodin Coils - the technical application, original testing and experimentation, and replications and results. If you wish to discuss the number theory and non-practical/non-technical matters, visit the Marko Rodin thread.

Rodini Solid State Oscillator

This Experiment involves using a Rodin Coil within Bedini SSG circuit and resulting in a solid-state resonant oscillator with notable high-voltage and high-speed charging and even current-driving abilities off the charging lines (I light a 14W CFL off of the lines going to charge the caps). Because of the combination of Bedini and Rodin, I have nicknamed it 'Rodini'.

I am no expert, but the Rodin Coil's magnetic vortex is highly influencial here in its action upon the normally-wound trigger-coil. Most of the active field is contained with the inner circumference of the Rodin Coil, and the alignment of the normal trigger-coil with the Rodin Coil's field is critical to get any resonance and high-voltage.

A video of the Solid State Rodini can be found here :
YouTube - Rodini Solid State - bedini rodin coil combo

Included is a diagram and description of the setup for those wishing to replicate, it is the most current version (more current than the video), the difference being better wound trigger coil and use of 2N3055.

From a 24VDC power supply I currently have it so that the caps will maintain a charge around 120V while also lighting a 14W CFL to what appears to be full brightness. Play with the relative positioning of the coils to find the best spot - the neon brightness will increase/decrease as an indicator, and when you've found a good spot you'll see the capacitor charge rate increase and the maximum charge voltage level increase. Moving the trigger coil too far from the active field in the Rodin Coil inner circumference will cause a loss of resonance / failure to resonant.

Michael F.

Thankyou Gem once my eyelids are properly open ( its 4/47am here ) i shall begin work on this.

Many thanks again for tying it all together, much appreciated.

GEM,

quicky update, just got to finish winding another torus coil and re-arrange my 494 circuit, then ill be almost done for repping your circuit, btw..what frequency / duty cycle did you use?

David. D

[geminitric]

power supply and operating frequency

what frequency / duty cycle did you use?

Hey David, thanks for the quick work on the replication, I hope it works for you and perhaps you can get some better measurements :-) My lack of oscilloscope makes answering your question (and some of my own) difficult.

The power supply is coming from two ATX DC Switching Supply boxes (yoinked from old computers), each feeding off the 12VDC lines and connected in series to my circuit. As far as I can tell, it is constant DC, but I cannot be certain. I intend to use two 12V batteries to compare, but at the moment only have one.

When the oscillator is on, I've compared the sound of the coil hum to that of a computer signal generator and at around 2.9-3.1kHz they sound the same. To me, so grain-of-salt that. When it sounds like this, I get the best charge rate and level. I can change the pitch (frequency) easily by moving L1 around relative to the Rodin Coil. Many position tests led me to leave where it is at the moment (making this pitch of sound) which is slightly off-center. Your configuration may have its own sweet spot.

Something to note, the capacitor bank I'm using has been used in MANY experiments and is most definitely what they call 'conditioned' - this may have an impact on the efficiency of the circuit. Hopefully you also have well conditioned caps to test with ;-)

Hi all,

just a quicky, looking at the attached simple circuit....my bulb is light...this shouldnt be the case surely?? i thought an n-channel mosfet only conducted from drain to source when the gate is "high" ?

help.....im puzzled and my pwn circuits are no longer working !!....

p.s i should mention i have tested about 3 brand new mosfets now and the bulb light permanently.

David. D

[rave154]

folks, i figured it out ( eventually )

im not going to tell you what was wrong..because its too emabressing !

enough said

[stubbs]

Hi Rave154,

I am kinda new at this... The attached Image would be the correct way???

[rave154]

thanks stubbs,

you are correct

my mistake was.that i had the polairty of the battery on the "actual" circuit.backwards

didnt realise till about 3 hours was wasted

[rave154]

GEM,

im just as i speak, in the process of putting your circuit together, i got way-layed via problems with my pwm circuits etc..all sorted now :-)

as im going through your video and circuit...and hopefully you still have it arranged as it is in the video...could you try 3 simple tests just for
"sh*ts & giggles" as they say...

the coil of white cable that is the cord for the CFL lamp...
1) could you take that coiled up cable.and as the circuit is running...remove the standard coil..and replace it with the coiled up cable...

2) as another test...replace the standard coil as normal...and place the coiled cfl cable loosely around the standard coil...

3) loosely wrap the cfl cable around the rodin coil itself , as in, wrapped around the equator or circumference of the rodin.....not wrapped toroidely.

right then... here we go...

Hi Geminitric,

I try to access your link in youtube concerning your setup of the rodin coil.
I get the message from youtube "Content von Sony Music Entertainment. Es ist in deinem Land nicht mehr verfügbar"

Its some kind of copyright thing between Sony and Germany???
Would luv to view it...

[rave154]

stubbs,

try going to the usa version of youtube or the uk version..

someone tried to rotate a magnet inside the rodin coil(with a motor) and see what kind of waveform is formed in the coils?

[stubbs]

Hi Rave154,

I have tried everything to view YouTube - rodin coil version 1 construction video 0001

The germans have it locked down for some copyright issue with sony

I have found a few other plans on the net, and will start building it and the Rodini SSC this weekend.
I only wished to see what geminitric is using for the core, and if any other/new info can be obtained from this great work.

[geminitric]

my coil cores

The germans have it locked down for some copyright issue with sony

I used Youtube's audioswap process to add the soundtrack, and yes it appears that the song I had picked was copyright-blocked in Germany by Sony. go figure. So, I have switched the song, give it a few minutes and try again - PM me if it doesn't work and we'll try something else.

I only wished to see what geminitric is using for the core

All of my coils so far have been wound around green styrofoam donuts that can be found at Michaels Craft Store (Canada) or similar craft & hobby stores. The one I'm using in this setup has a 6 inch outer diameter.

I have found that putting ferrite inside the inner circumference of the rodin coil is beneficial, the more I can pile in there the higher my voltage remains across B1 & B2 when the light is on. I would suspect that a rodin coil wound around a ferrite core toroid would be a good idea, but I can't get any large enough at the moment and will have to hope someone else can experiment with that. I wonder if can make some sort of ferrite-glue-laquer sorta thing to coat around the wrapped wires of a rodin coil, and maybe lock in some of the field around the outside.

@rave - I'll take a few minutes this aft. to try out your tests and let you know! I figure you mean me to test what effect (if any) the big cable has because it is coiled up on the way to the cfl.
