Hi all,

Just completed the coil.
I do not know if it will make a difference or not??? I used 23AWG Silver mag.
wire as in the B. Boyce Coil. The core was wraped with a Static tape from 3M
and again with a good elec. tape. The Coils have 1.5 Ohm each. Pics below...

I will start the SSC in the A.M..

Stubbs,

glad to have you on board,

nice job on the windings there, very neat

it will be very interesting to compare the results with your coil and the "core" against our coils which of course are air cored.

Hi all,

i have just finished winidng a toroid ala' ossie callanan style ( see his youtube vids ) and have it threaded through the middle of the rodin coil befire joining the two ends together to form the toroid, so the two of them are linked like two links of a chain.

this should fun testing...then again its probably got "Epic Fail" written all over it llol

attached is a diagram of my rodin + toroid configuration, hopefully makes sense

using the two windings of the rodin in series being pulsed by a 494 pwm circuit and using the standard toroid going to a FWBR,in turn to a cap with a 12V light bulb across it...

i noticed, as i rotate the standard toroid "through" the middle of the rodin..the voltage changes from position to position...as i approach the position on the toroid where the two ends have been joined together and this place is in the middle of the rodin..the voltage increases to a maximum, as i move away from that position the voltage diminishes.

Wow... What a night Destroyed a couple 2N3055s and a FET
to top my evening.

This morning I decided to use an optocoupler/HEXFET (IRFP450) combo.
Guess what??? It worked

STubbs,

congrats, i too destroyed a couple of 2n3005's, they dont seem to like the high frequency, althugh my scope was having a problem reading the freq, it seemed fairly high, and the trans got VERY hot.

load details etc?

p.s

im just about to wire up ther same as you, opto going to a mosfet, however, the mosfet is going to my ignition coil.....high voltage instead of current this time.....just a hunch.

Thanks,

David.D

Wee...

This is fun... The Cap bank is only 1570uF; need more...
This curcuit will charge to 420V quickly... Pics below.
I have posted a video, YouTube - Rodin Wound 6in Ferite Core it is not as neat as Gem's, but I guess will do.
I kept lossing my train of thought through the video.
The Power supply I have limits the ampere to user setting.
Nice thing to have when tinkering...

Does anyone know where I can get my hands on large Caps???
Here in Germany resources are limited /hard to find.

Stubbs,

nice work to get going so quickly

i have the same problem re:- capacitors, i only have a small bank of caps that are voltage rated to 400+.

interesting that youre up to 400+ volts, i wonder if its because you have a solid core as opposed to mine & Gem's air core.. see..i told you your solid core would make an interesting comparison.

might want to experiment with raising the rodin above/ below the trigger coill...and observing what happens with the input / output....as i noticed some quite significant changes.

keep up the good stuff

Rave,

I wish I had a few 1000mF Caps laying around.
It was a pain to get 1570uF... I think this just may be part of the big pic.???
I notice that when I move the trigger coil; the deeper the tone, the faster the
Caps load. "no effect on power supply"

Gem,

What software do you use to illistrate your circuits?
I wish to duplicate what I have here; Short term memory ;o)

[stubbs]

Found something new.... I put 4 un-cracked rows of staples in
the center of the trigger coil and fired it up. Cap voltage hit
420V in ~20Sec and my 40W 220V Halogen burns a couple of
seconds longer... wow

Hi all,

i'm going to post this here, though it could just as easily go on the main Marko rodin thread. Parts of this ive already touched upon, but ill repeat and clarify with the little bits ive learned since then from others and my own dabblings.

so far, we can do one of the following with the Rodin coil....

1) pulsed DC, makes a NEO jump around, its fun for a while to watch, if your clever you can even get a cylindrical NEO to rotate and then have a pickup coil to generate, collect the flyback spike etc etc, all the usual stuff... but....... no OU !!

2) AC, as per Jamie Burturoff, makes a spherical NEO rotate, also perhaps, creates a monopole magnet in a steel bar ( though this is perhaps in dispute )...but again.....no OU!! ( this is NOT a criticism of Jamie btw )

so, Marko is quite emphatic that the coil's "heartbeat" so to speak, is 1,2,4,8,7,5...and repeat...
well, pulsed DC is no where near this is it?... pulsed DC is 0,1,0,1,0,1

AC however, is a little bit closer to it, because at least AC is a continually changing voltage value....no...its not 1,2,4,8,7,5.....but its perhaps closer to that...than is 0,1,0,1,0,1...

heres my idea, i want to pulse one winding of the Rodin coil, with DC, but a discrete set of voltage values, obviously in the sequence.. 1V, 2V, 4V, 8V, 7V, 5V .. and repeat...and see what happens.

as best as i can tell, a fair way to do this would be to use a PIC32 setup.. which i have...however im new to it ( although not new to programming by means ).. so i will need some help with connections, components etc..

i "think" it might be possible to use the DAC on the PIC and maybe output that to a transistor which in turn would control what voltage ( via its resistance ) is put across the coil.....is this feasable?

Help, if you can.

David. D

p.s STUBBS, keep going.

Hi all,

I have changed the pickup coil with a 2"x3/8" Ferite Bifillar 150 24AWG wraped core and added a 10000uF Cap.
The voltage at idle reaches 500V within seconds. When I connect a 11W CFL the voltage settles to 180V and
stablizes.
