Core

GPilot,
What kind of core does your coil have? Can't see from the images. You must have an iron core of some kind with the mass of a bicycle wheel.

Right now i am using a solid steel rod that is welded to a small bracket that i screw to the bkard 1/8 of an inch from the magnets. I havnt mounted it yet, but will today. Just wanted to know if the direction the coil faces matters. I am waiting for some copper coated steel weldng.rods to arrive. But i should be a ble to work with the steel rod for now. You can see the rod.on the bottom left of the picture.

Have you read the information I posted on an earlier thread about how to check out your coil? I gave you a link to that post. I am not going to retype all that information again.

@citfta, yes i.saw the link, and i had no sucess trying to get the coil to push the magnets away. If.seems to arrtact the magnet anyway i connect the wires. If i swith.the power wires and or.the trigger, i get.the same result, which is no result. I cant even.make an.electro magnet with my coil..dont know what to do now

Compass

GPilot,
Coil orientation matters a lot. So does magnet orientation. Magnets should have north side out. Coil should have north side facing the magnets. Get a compass. Power your coil. With your core in the coil, bring the compass near the coil core that faces the magnets. The compass needle arrow should point away from the core. The south side of the compass needle will be attracted to the north side of your coil. Many people get their power coil correct, but hook their trigger coil backward. This causes cancellation.
Good luck.

Hi folks, Hi gpilot, maybe the 23 gauge trigger coil you are using is not sufficient to trigger the proper bias of the transistor for the amps that the heavier 18 gauge wire is asking for and may explain the slow rpms on your previous tests.
The 5 strand coil the mountain bike wheel we are using, are all the same wire gauges, though they recommend one or two gauges higher for the trigger coil and you are using 5 gauges higher for your trigger coil.
So if your going to use the 18 gauge primary wire, then go with 19 or 20 gauge for the trigger or the same gauge.

#20 and 23 wire, had to check

Try to use a led to CE transistor while turning the wheel to see if transistor is opening if not you have to increase thin wire.

Where do i connect the led? From what to what? Then the led should light up as i spin the wheel? Should the led take.place of the neon between collector and emitter?

You can do it after the emitter so that you know that the transistor is switching on.
Yes it should give pulses when you move the magnet infront of the coil otherwise transistor not switching.
Leave neon there.
If you used thicker coil for base then as skywatcher told you or wind coil again with thinner one or try to increase it's lenght.

i used the same gauge wire bedini recomends. I need a compass. Also know my coil wires twisted together once or twice while i wound it. Is this a problem?

Getting the coil to work

Hi Gpilot,

Your coil looks fine. Your diodes are ok too unless one of them is shorted out or dead. The first thing you have to do is get the power winding of the coil working. Connect one end of the coil winding to the positive side of your battery. With the coil close to one of your magnets tap the other wire of the coil to the negative side of the battery. It should kick the magnet away. If it pulls the magnet harder toward the coil instead of pushing it away then you can either turn the coil around and use the other end of the coil or just swap the wires. If it does not do either then you have a problem. Either the coil is bad or the battery is dead. The problem with the coil may only be that you haven't cleaned the enamel coating off the wire good enough and you are not making a good connection to the battery. Do you have a meter you can use to check out the coil? The coil will work much better when you get a proper core for it. A solid piece of metal is not a good core for the coil. A bunch of soft iron wire packed into the center will work much better. You don't have to have the welding rods for your core. You can use some electric fence wire or old coat hanger wire. Almost any soft iron wire will work much better than a solid core.

If you don't have a meter to test your coil you can use a small 12 volt bulb like from the tail light of a car. Connect one end of the coil to the positive of the battery. Connect the other end to one of the connections on the bulb. Connect the other side of the bulb to the negative of the battery. The bulb should light up ok. If the bulb does not light up then you have a broken wire in the coil or you haven't cleaned the enamel off the wire like I said earlier. Until you can get the coil to kick the magnets away there is no use working on any of the rest of the circuit. You HAVE to get this part working first. I have built several of these circuits and have helped many other people to get theirs to work.

Respectfully,
Carroll

so, i got a compass and my magnets were on backwards. I put them on the right way. I tried to run it again and still nothing. Not clear on where the led should be or what it connects to. I cant get the coil to push the wheel. Also cant deturmine north of my coil. I seem to have made every mistake possible. I still cant tell if my circuit is working wrong or if i need to wind my coil tighter and without any twisting. Please help

[citfta]

I am trying to help

Did you do the test with the light bulb and your coil? If the compass does not show a north or south on the coil then the coil is not working. The wheel will work even if you have all the magnets the wrong way. You would just have to reverse the connections to your coil so you would have south opposing south instead of north opposing north. Some people believe it works better if north is opposing north but it will still work with south opposing south. For right now we don't need the led. Did you carefully scrape the enamel off the ends of the wires? Do you know your battery is charged up? Can you put a small bulb on the battery and get it to light? If the bulb lights when on the battery then do the test with the coil and bulb in series with the battery and tell me if the bulb lights up.

Short

Another posibilty is a short between the 2 windings. Use a meter or test light, Carrol describes, and see if there is voltage on the unconnected winding while the battery is connected to the power coil. If there is, you have a short between windings and must rewind the coil. Magnet wire is easy ti skin.
