Hi everybody,
I'm reposting this pos I hope in the right section.
Hi everybody,
I've built Bedini SSG using Daftmans Draft. Unfortunately without success for the moment. I've done different versions of(coils, rotors and also of the general set up). And have also changed all the components several times just in case,
I'd appreciate if someone could give me a clue of where it can be going wrong.
Facts:
1) I'm using a 14.4V power supply.
2) I'm using exactly the same wires recommended by Daftman in videos. (.71 mm for the run coil and .223 for the trigger)
3) The circuit only works when the resistor is at full resistence (980 ohms) if I lower it down it stops working. The coil does a slight beeeeee noise.
4) When the the coil is doing the beeeee noise it gets hot (not too much) and attracts the magnets but when I push the rotor round it won't last for long. What I see is that there is no repulsive force going to the magnets when they pass by the coil. It seems as the transistor is not doing proper work. The trigger coil looks to me doesn't power the transistor (TIP 3055) to give a load to the run coil and get the magnets going round.
5) It seems to me it has something to do with the potenciometer but i don't know...
Has any body got any clue.
I here attach a link with some photos of the circuit. I've double checked all conections... I've also tried getting less magnets (First set up was whit 6 magnets (15mm diam. x 8 thickness) and now i've set it up with 3 magnets.
I've also given 300 turns more to the trigger coil (now it has 800 turns) and 500 the run coil.
Here are the photos:

Thanks for your help.

Does any body think that doing a new coil with a bifilar in the trigger side (the wire is very thin 0.22) would improve something?

Try replacing the transistor.
Please make absolutely that the magnets are in the right orientation all north.
See this video it may help You to identify the orientation of your magnet’s.
Also check your variable resistor (pre-set) is 1K

Hi Teep,
Thanks very much for your comments. As said:i've changed all the components including coil, and also rotor (I started with a big woodden plate with 16 magnets). And also have changed direction of magnets...
One question:
When de rotor is still do the magnets get atractted o reppeled rods of the coil?

Fischer |

With power off attracted.
With power on repelled from the coil.
Please check your coil connections are correct. 450 turns will run just fine but your 800-turn coil is ok so you don’t need to build a new coil.
The only thing I cannot see in your photos is the coil connections, yes I can see the pins but not the coil wires there self. Also make sure the coils are isolated from each other and not got any kind of connection between the 2.
Again make sure the coil connections are connected in the correct way, it’s important you get the ends and the start of your coils connected correctly.
And as a last test remove variable resistor (pre-set) and the 100 ohm resistor and replace with replace with 680 ohms resistor.
Sorry I’m away for the next 3 days from the time and date of this post.

I'm back... been a tad busy...
Follow teeps advice and post back ether way... I'm avaliable-ish over the weekend so in teeps absence i'll try to fill in...
To check your coils are not foobared... use a multimeter to check the resistancies across the coil and between coils...
Their should be NO conductivity between coils...
FAO: TEEP
Isn't the neon connected in the wrong place?
Should it not be diode to Positive terminal?

Hi Teeps & Comwarrior,
Just done what Teeps recommended. And also have rebuilt the circuit, and replaced all the components( Transistor, diodes, resistance and pot). The only thing thats left is the coil.
My next step is to try and rewind a coil. Before doing this as it's the second one..I'm going to try and put my first coil as a second trigger coil. I'm using 0.21 mm copper in the trigger (might be to thin??)
What would you recommend as a coil??
regards,
Fischer |

hi fisher,
just want 2 say that 0.21mm for Trigger is not thin...i used 0.25mm in my first Bedini setup...it worked perfect.
u can make 2 coils instead of 1 bifiliar 1...i found that easier the first time.
1 coil is 0.71mm - RUN
1 coil is 0.21mm - Trigger
put them @ 180 degrees of each other.
thats the way i did it also in my first atempt on my Bedini setup and it worked perfect aswell.
u may want 2 put 4 magnete on your Rotor @ 90 degrees each and all 4 north outside facing.
hope this help u out abit...ima no pro on this stuff...just know some basic stuff...:))
Peace!

Hi BiDaDiKuNuKu,
Nice to meet you. I've been looking at your set ups and videos. Copied your first set up cable by cable. The only differences are in coils and rotor. I have a doubt: I have I think very strong magnets( 15 mm Diameter x 8 mm thickness (7kg of atracting strengh). Question: does this influence the coils size?
I have just done test that you recommended: I put the 2 coils I have: One bifilar (run + trigger)and only connected trigger coil of the other bifilar==>doesn't work. It doesn't even do beeeee....when I connect batery (14.4V).
Another thing I don't understand is when I put power on and the coil starts doing beeee, when I turn rotor it stops doing beeeeee (the current stops going through the coils). Power off and on and "resests".
This depends on the pot, I have to put full 900 ohms to get the beeeee, if not no current going through... which is not logical....more resistence less current???
Another question: I've seen in one of your vids that when you put power on the coils atracts the magnets?? Is that so??
How many turns to the coils do you recommend??
Regards,
Fischer

Hi,
Another that is troubling my understanding is that when the magnet passes by de coil its sopposed to activate the transistor and give "power" to the coil to activate de electromagnet....when the magnets passby my coil nothing happens its atracted to the coil and nothing else....so it turns a few times and ends up by stopping???

ok, the "beeeee" buzzing is caused by a resonance effect, basically the circuit is self oscilating, IE triggering itself...
This tells me your circuit is ok...
The fact that it stopps oscilating when you spin the rotor is ok.
question1:
When you spin the rotor does it draw power from the PRI battery?
If it does then we know it's triggering and trying to pulse...
question2:
How far away is the magnet from your core?
if it's too far away the magnetic field is reduced by the time it gets to your magnets.
as a rough guide it should be between 5-10mm, when you spin the rotor if it makes a 'clunk' as the magnet passes then it's too close, you want it just on the edge of making a slight 'clunk'...
Question3:
Make sure that the primary battery is reading atleast 12V while your trying to spin it (upto 14volts is ok). Too low a voltage reduces the strengh of the coils magnetic field...
How 'free' is your rotor? the less resistance their is the faster it will run...
Also, After ree-reading your posts, the 'BEEEE' is not what your looking for... turn your pot all the way down and re-try spinning it... Only when you've got it to pulse do you then start turning the pot up...
Question4:
What is it your using for the coil core? and how thick is it?

I just looked at your pix very carefully...
i'm concerned at the size of your core in relation to your magnets and the thickness of your coil...
The core looks thin... what are you using?

Hi Comwarrior,
To answer your questions:
My two coils are:
1) The first one I did was 12 mmm core (oxiacethile rod (3mm diameter). But I think it is too long (90mm including wooden parts). 520 turns of .71 mmm run, 0.225 trigger.
2) The second coil 10 mmm core (copper rod 2mm diameter). I did this one shorter about 53 mm long inlcuding wooden part of the coil. 520 turns of .71 mmm run, and 820 turns (added 300 more in a second step 0.225 trigger.)
The tests carried out are alot:
Put the core near (2/3 mm)put it far 20mm...
The rotor is quite smooth...
I've just tested the circuit removing the pot....But the beee noise is necesary if it doesn't beeee the magnets are not even attracted by the coil, even before starting to turn the rotor.
And right now as soon as I start the rotor the bee noise stops and the hole thing stops....power off and on, and beeee noise starts again???
Thanks for your help.
To tell the truth I thought it was going to be more simple than all this. But i don't like to start things and leave them unfinished. Thanks to all for your help.
Regards,
Fischer

Sorry forgot to answer question 1,
When the beee noise is on it drwas power obviuosly from bat, but as I turn the rotor and beee noise stops and power is not drawn.
Bateery voltage is steady in 15.00- 15.80..

ok, first off i have no idea what a oxiacethile rod is... I even did a search in yahoo for it and no results came back...
The cores i use are 15/16mm in diameter filled with 15 M4 threaded steel rods...
I once tried a 10mm core and got the exact same results... so
Next step, you need a 15mm core on your coils with a core material atleast as dence as steel, preferably iron...

Thanks Comwarrior,
I'll do a 15 mm core coil. Do you think if I do 2(one trigger and one run coil) it would be better?

the issue with seperate coils is alignment, both cores need to be aligned with the magnets...

Hi Comwarrior,
Before starting wiht my new coil, I did a test: replaced my 15mmX8 magnets by smaller ones (6-7mm diameter)...the result is exactly the same. tested it with my two coils (12mm core coil and 10 mm core coil)....
I don't know if doing a new coil will be the solution.
What do you think??
Another question, when power is put to the circuit are magnets atracted to the coil or pushed from the coil?
Regards,
Fischer |

Hi,
Just finished my new 16 mmm core coil. And unfortunately, nothing has changed. i'm getting a bit crazy. I really don't understand, what the deal is. Anything more that seems odd to you?

hey fischer i have a quick question...your wire for your coils what is it...is it enameled meaning does it have an outer coating on the wire?....also you might have a short in your coil....or maybe this "bee" noise is it oscillating?
