Missing

@zogo,
It looks like you may be missing something. I do not see a neon bulb between the emitter and collector of your transistor. There should be a bulb or charging battery there. At the very least a capacitor. Study the diagram acedragoni posted for you. Without this "load", your transistor will go byebye. It will stop functioning. It doesn't take much. I have lost a couple or the "93"s which are rated 500v and I had bulbs. My coils are 7ohm. I have actually blown the bulbs to pieces. So get a load, as diagrammed, on that machine.

PS Quit trying to read voltage until you get it spinning. If its not spinning, it's not switching right and voltage reads are useless.

Zogo Tachy is telling you the truth if the rotor don't spin no voltage will come; cause voltage is created by fast switching of the transistor.

Hi Randy, and thanx for you post.

Ok... I am under the assumption that the trigger coil needs to generate at least 1-2 volts in order for the transistor to be able to give the pushing coil a fair amount of voltage, thereby a good push. But I may be wrong, as far as I can understand from your post.

Can I use a hallogen 12v bulb instead of the neon bulb?

And can I conclude from your post that it doesnt matter how low voltage, 0.01v even, my trigger coil produces, the transistor will still open up, and let the juices flow to the pushing coil?

Hi zogo,

I don't think anyone else has mentioned this but are you trying to run your machine with the coils as far away as the picture you posted? The magnets really should be ceramic as someone else has already said and the coils need to be about 1/8 of an inch to 1/4 of an inch from the magnets. Also you don't need 2 magnets stacked on top of one another like you have them. If you get the coils in the right position you should be able to generate the .6 to .8 volts needed to turn the transistor on. By the way transistors turn on and off, they do not go open and closed. An open transistor is one that is burned out. If you do not put the neon bulb from the collector to the emitter as someone else has already said you will get an open (bad) transistor. The neon will fire at about 60 to 70 volts and save the transistor. And you cannot use the 12 volt halogen bulb. It will absorb all the spike you are trying to get for charging the second battery. And it will probably keep the coil from turning all the way off which will also keep the machine from running.

Good luck,
Carroll

Hi folks.
Hi zogo.
Cifta is right, but I will add a suggestion: keep trigger coil and power coil
wound on the same core not separated from each-other.
Till you grasp the hang of how it works better stick to ceramic magnets.
If you have no ceramic ones then scrap apart an old speaker and carefully break the round magnet from it to 4 pieces.Then use it for your ssg thing.
Mine was scraped from old magnets and scraped old copper wire enameled/transformer wire.
old rusted out welding rods are great for your project + add diode to base-emiter and neon bulb to collector-emitter...
see here for detailed info:

again stay with basic setup at least now and once you understand the principle go ahead for wild projects...
see here too:

Darcy Klyne's Bedini Monopole Motor Replication

I hope you have the patience it takes to be successfull.
btw, my setup was also hand-wound so keep trying.

Hi Carroll.
I was actually trying to create the Bedini Schoolgirl version like on this page http://www.energeticforum.com/renewa...choolgirl.html, and then I got mixed up in neon bulbs and what not.
My coils are not fixed, so I am able to move them arround at my will (experimenting with the position and distance from the magnets by hand). In your post, you mention that the trigger coil produces .6 to .8 volts to trigger the transistor. Mine only produces .01, and I think that this is the problem which I don't understand. (I have 26# wire and about 200ft of it using a core consistent of metalic rods glued together).
I am well aware that I need some mechanism on my transistor to avoid it being burned once the machine is working, but I havn't got that far yet.

Right now I'm still trying to make my trigger coil produce a bit more volts.

Yesterday I've setup the entire circuit with a capacitor as tachyoncatcher told me to. I've measured the transistor like acedragoni told me to, and added another 9v battery in serial as Peculian told me to.
Then I inserted a small magnet in the center of pushing coil (as it has an air core) and was able to move that small magnet a bit inside the core once I spinned the rotor by hand as hard as I could.
So this means that the circuit is in working condition, but there is not enough power comming from the transistor to the pushing coil.
I then substituted the trigger coil with a AA battery, and the pushing coil worked well. So this can only mean that my trigger coil is crap. I will try to find some cheramic magnets somewhere to test with, but in my logical sense, neo's should create a much larger voltage then the cheramic ones, if the coil is close to the magnets.

I've read something about saturating coils, maybe that's what I'm doing? Does it matter if the magnet is larger in width and height then the core of the coil?

PS: Thank you all for your posts.

More Iron

Hey zogo,
You will need an iron core in that pusher coil. You don't need to glue them, just pack them in there so they don't fall out. Ideally, your magnet is as long as your coil is, in diameter, but this is not necessary. Your magnet is as wide as your core is wide, but this is not necessary. You see, its all experimental.

Hi Randy.
That you can bet on I will. The small magnet mentioned earlier was just to test the circuit.
It moved a little bit each time a magnet on the rotor passed the trigger coil. So I know that the circuit is working, but I just cannot seem to generate enough current from my trigger coil.

Citfta mentioned that he measured 0.6v on the trigger coil. I can only get 1/60th of that and generate 0.014v giving the rotor a hard push.

I just cant understand what I`ve done wrong. I bought another set of neos today and tried with those, still no joy. Went home to my dads, opened up a speaker, took the magnet and tried that one too. I got 0.03v using ceramic magnets, so I am frustrated.
In a week or so, I will get a bifilar coil with 800 turns of each wire from a professional, hopefully this will do some good.

Does the trigger coil produce more current when hooked up to the circut? Apart from the fact that the rotor speeds up thus generating more current in the trigger coil.

Another fun fact I have seen was that if I unhook one cable from the pushing coil, I was measuring 12v at the pushing coil. Hooked it back on, I got 0.

Hi zogo.
LOL , I hope you didn`t destroyed a good speaker
keep that magnet, you will surely need it somewhere on the long run if not for the moment.

Well, maybe I am too optimistic in this yours project but I think it might as well work fine. Bifilar coil is a win in Bedini Energizers. Once you get it to work you will see some benefits right away.

Can you please specify what exactly do you mean by this question ?
I guess you need to ask more about things you see you are "stuck" , because here in this forum there are many guys with lots more experience than me and others who already contribute to your topic.
Now another suggestion:
Get rid of the aligator fancy cables, use soldering and as short as possible connecting wires
to your circuit. I am making a wild guess and say those aligator clips is part of the whole
problem you are facing now.
Again, stick to the basic construction guide/tutorials and use welding rods as the core of your bedini energizer or SSG.
See if the batteries you are using have enough power to pulse your power coil properly.
Keep trying.If stuck somewhere just ask.
Regards.

Peculian, the speaker was working, but it aint no more
It was from my old car, and I would never have used it, and it would just collect more dust.

What I meant by my question was:
A coil produces current when a magnet is rushing by it's center. The faster the magnet goes by, the more current gets created. I measure 0.014v using a voltmeter when my magnets rush by the coil (at maximum pushing speed by hand). This measurement is made when the coil is not connected to anything, other then the voltmeter. Now the question: If I connect the coil to the circuit, would the circuit have an influence on the current produced by the trigger coil?

How about if the coil is a bifilar coil, does the thicker wire ("pushing wire") aid the thinner wire ("trigger wire") in creating current by having a greater magnetic field in the coil? What I'm trying to ask is actually, does the bifilar coil do anything good other then help on the timing? Will a bifilar coil create more current with the exact same components, instead of having 2 seperate coils?

Voltage

zogo,
You need to check out ohms law. Voltage is directly affected by the circuit that is connected. Hook up a 110v neon as I suggested earlier and you will get a 100+v reading off that circuit. Hook up various resistors in place of that bulb and you will get various voltages. This is why I suggested you quit trying to measure voltages and focus on getting it spinning. If it is spinning then you have a successful, completed circuit.
The trigger coil is for... triggering. It will produce enough voltage to turn on the transistor at the right time. This then activates the pusher coil to push/repel the withdrawing magnet from the pusher coil. Then there is the collapsing field. This shows it better than I can explain.

I have limited Internet right now, so my posts Will be intermittent. Lightning hit my home and took out almost every appliance, tv, computers, you name it. If it was plugged in, it's done. --ouch-- Even my furnace/air-conditioning and ceiling light fixtures. Wish I could have stored that energy in some batteries.

If there is no "load" your transistor byebye. This will stop the operation. It will not cost too much.
