Water Sparkplug

Awesome detail.

Thank you

Hi DonL
I used some copper coated welding rods as the coil core. I took three wires, each about 50 meters long, then I twisted them together so that they form one thicker wire (Litz wire) and then I just wound that big wire on the coil core. The coil has about 400-450 windings. All three wires are AWG 21. But there is no need to twist the wires, there is no need for copper coated welding rods - any bolt will do fine. Also the wire gauge is not that important, you can use anything from 18-25. Just the windings should be at least 400
Also you don't even need a trifilar coil, you can just as well use a bifilar coil. With this setup I can go with the spark discharges as high as 200Hz using 2.2uF 450V electrolytic cap. Then I attached two more caps in series to reduce the capacitance to 0.73uF and I could go as high as 350Hz. At last I replaced the electrolytic caps with two 1000V 0.88uF polypropylene pulse caps in series. Now I can go up to 550Hz with no problems. I guess that if I decreased the capacitance more, I could go even higher, but there is no need for that. Also I think that this could be about the limit that the ignition coil can handle. But the best part is that this whole circuit draws only 100mA from a 12v battery
Great stuff this Bedini self oscillator


Edit: If I decrease the spark plug air gap to about 0.5-0.7mm, I can rise the frequency up to 1.5KHz

Hey guys,

I just got done soldering together 120 1N5408's!!! I re-watched Mr. Bill's Nexus video and counted his diode strings. He has 4 strings of 15 diodes each string. My question, is it wired the way I think....parallel with 30 in each string OR the other way....parallel with 4 strings of 15 each? Which way would be better and which way does Mr. Bill have his, near as anyone can figure? I will be testing this circuit tomorrow on an old, points controlled lawn tractor and want to be as close to the way he did it as possible. I know he said he "over-engineered" the circuit, but I figure If I do it the same way.....and it don't work.....I can rule out it being something I changed that made it not work. I at least don't want to change up the circuit until I understand it a little better, THEN I'll try to make it more efficient. Well, fast aproaching is the end to another day in the neighborhood, later................................Mike

He stated that he has two strings of 60 diodes in series (60 per string) totaling 48kva at 3 amps. The two strings are ran parallel giving him 6 amps.
He stated that one string would be plenty because he was only drawing 100ma.

Good luck with your testing . I Hope to be testing mine this weekend also.

Hope it helps,

agreeing

I was being sarcastic Greg . It's obvious it's way over priced compared to the setups found here.

Hi,

I know ... I was agreeing with your statement:

"So more like no thanks. FE should be what it says FREE!"

...absolutely NO ... as in "NO THANKS"...

Peace,

Greg

Hi Broli,

Absolutely NO! Besides the magnitude of their spark is probably not what we need in water as fuel.

already done!

The seem to contradict themselves...



but if you look at the price page...



Wow cost advantage indeed. The setups the guy's are playing here are probably under 100$ and that included an engine!

So more like no thanks. FE should be what it says FREE!

WTG!
Nice progress!

Please post your detail componets and include the number of windings on each set of wires in your trifiler coil. What type of coil did you wind your transformer on? Paper coil? ferrite core or rod? toriod?

Thank you for keeping us all posted.

(just replace that battery with a cap. I have not tried this by myself)

Here is a pic of my coil:



And this is my latest circuit with no booster side attached yet:

Hi all,

This is a quote from Over Unity by Mr. Tesla:

"Its already done"

Light Speed Engineering - Products - Ignition - CDI Features

Peace,

Greg

The seem to contradict themselves...

Finally, the components for electronic systems are all mass produced, giving electronic ignition a distinct cost advantage over replacement parts for magnetos.

but if you look at the price page...

PLASMA II PLUS: 4cyl. Hall Effect Module* $1,315.00

Wow cost advantage indeed. The setups the guy's are playing here are probably under 100$ and that included an engine!

So more like no thanks. FE should be what it says FREE!

VW conversion

Hi all,

This weekend I will begin converting my '64 VW Bug to the Gotoluc/Lindemann CDI. Frequency issues are no longer a factor in my circuit. For all of you having problems with the Nexus, I suggest you consider isolation problems. The incorporation of the isolation transformer in my circuit is what created a stable configuration. Also, turn your voltages down. The effect can be brought with as little Cap charge as 75 VDC with the CDI. By the descriptions I've read and as many inverters are being fried and plugs getting welded, it sounds like you're building arc welders ... just joking ... Great efforts!

The bulk of challenge with the VW will be to create a second set of points in the distributor housing. There is room ... I just don't know if I'm skilled enough to pull it off.

Will post all steps. Peace,

Greg

Hi, guys.
To help solve the charge pump issue, I thougt this idea it's a little bit better than the inverter.
Inverters work at 50-60Hz (sine signal). After passing the bridge rectifier, the frecquency becomes 100-120Hz.
Now, why use (and sometimes burn... ) inverters to charge capacitors when your car allready has a better oscilator device as standard?! I was talking about the CAR'S ALTERNATOR.
It makes the electrical energy for the car. The current is AC type and has hundred of Hz at idle. As the engine's rpm rises, the frecquwncy rises also. Adding a bridge rectifier, it doubles the frecquency!
So, that is what I suggest:
alternator -> usual 7.5V/230V transformer -> bridge rectifier -> capacitor.
Yes, it's not as good as a DC-DC converter that works at much higher frecquency, but it's better than inverters. And yes, the bigger the transformer, the quicker the capacitor is charged.
Look at the schematic attached.
All the best for all.

Just looked up the tracking number from UPS, my 1N5408 diodes will arrive today!! Looks like the rest of my day will be spent soldering together diodes. Just a wierd thought, will this Nexus circuit even work on the bench Or does it have to be hooked up to an engine for the circuit to perform it's assigned task? Just thinking out loud. Bill never did operate the circuit in his video except with the engine already running, hmmm..............

I believe that the circuit requires the engines ignition system in order for it to work properly. Don't quote me on that though. I still have not completed my circuit for testing. I plan on testing it on a vehicle with a single plug first, and then if it functions as stated, I will build the cross talk preventer and implement on all cylinders.

Nice Vid.



I think that was the reflection of the spark plug off the coil.

Hi CPU3rother,

Yup, That's exactly what it is ... a reflection.

Thanks. Peace,
