so, i scraped the enamal from the magnet wire, which i never did before. I got the light to come on when connected to the coil and battery. It isnt as bright as when only connected to the battery. I got the coil to repel the magnets as well. But when i hook up the circuit, it doesnt work. To this point, i feel like i am very close.

That is good news

Hi Gpilot,
OK, now we know the coil works. The light should be dimmer when connected through the coil. That is ok. Did you connect the negative side of the coil to the collector of the transistor? You need to keep the same wire going to the positive of the battery as you had it when it kicked the magnet away. You need to mount the coil next to the rotor and then give the rotor a spin. If you still have everything connected like your earlier pictures then it should start working. You may need to turn the pot all the way down and try again. If it does not run now then you need to switch the two trigger wires. Do NOT make any changes to the power winding wires. Did you get a proper core for your coil? If you do not have a good core then it will be harder to get the trigger winding to turn on the transistor. Your coil looks to be big enough it should be able to turn on the transistor easily with a good core.

I will try again with a coat hanger core. Right now when i try to run the machine, the wire going from the negative of my primary to the emitter keeps burning out. I also tried to bypass the diode that comes off the collector to see if the diode was bad. I get a spark when connected directly to the collector, but not when connected to the diode.

Hi Gpilot,

If the wire from the primary negative to the emitter of the transistor is burning out you have a serious problem. It sounds like you transistor is shorted out. You should get a spark if you connect the negative to the collector. That just means there is current going through the coil. If you connect the negative to the emitter there should be no spark. Have you tried to run it without the neon bulb from the collector to the emitter? If you have, you have probably blown the transistor so that it is now shorted out. Never try to run this circuit without the neon bulb connected from the collector to the emitter.

To make sure about the transistor you need to do the following steps. First disconnect everything from the base of the transistor. Then connect a bulb from the positive of the battery to the collector of the transistor. Use the smallest bulb you can find for this test. Like a 12 volt grain of wheat bulb or small bulb like is used in the dashboard of a car. Now touch the negative of the battery to the emitter of the transistor. If the bulb even glows a little bit then the transistor is bad and will have to be replaced.

Please do this test and then post the results. Also if you have made any changes in the circuit from the way you showed in your earlier pictures then please post some new pictures. As far as I could tell from the earlier pictures you had everything wired up correctly. One other thing I can think of is this. I cannot tell for sure in the picture that you had the emitter and base wired correctly. If you turn the transistor the wrong way you would have the base and emitter backwards. Make sure you have them wired correctly. If you have them wired backwards you have probably blown the transistor that way too.

i did the test with the light and got nothing. I switched the transistor with another and the wire from the primary to the diode stopped frying out. When hooked up, the coil repels the magnet and the wheel comes to rest between the magnets. So it seems the problem is with the trigger. I have switched the trigger coil connections and still nothing. I made a new core from coat hangers as well. I will post some more pics and a youtube link that shows what happens when connected. Thanks for your continued support.

Gpilot,

Are you saying the coil is staying on all the time and keeping the magnets repelled? If that is what is happening then you probably have the system in self oscillation or the new transistor is shorted. Here is how to test it to see what is happening. Disconnect the trigger wire from pot. Then apply power. If the magnet is stilled kicked away then your new transistor is also bad. If it does not kick the magnet away then you just need to get everything tuned up. With everything connected up you need to adjust the pot to get everything to work correctly. With the power off turn the pot all the way one way and then apply power. If it does not kick the magnet away then give the wheel a spin. If it is still kicking the magnet away then turn the power off and turn the pot all the way the other way and then turn the power back on and try again. When you get it to not kick the magnet if it does not run then turn the pot a little and give it another spin. With some adjustment you should be able to get it to run now.

Hi again,

Ok the first thing I see wrong is how you have the pot connected. In your earlier pictures you did not show how the pot was connected to the trigger winding. You need to move the trigger winding to the center leg of the pot. The way you have it connected now the pot is at full resistance and the adjustment is not doing anything. Also did you try putting power to the circuit with the trigger lead disconnected from the pot? You need to try that to make sure the transistor is ok. With the trigger lead disconnected the coil should NOT kick the magnet away. If that test is OK then connect the trigger lead to the center leg of the pot and try again by first setting the pot all the way one way and then with it set all the way the other way. If that does not work then reverse the trigger leads and try everything again. Please follow these steps in the order I have given them. If you jump around in the steps then you will not get the correct results and will not be able to tell what is going on. If you can make a video of these tests so I can see the results.

Close

@Gpilot, your getting close.
@citfta, Magnificent instruction.

Hi folks, Hi gpilot, in the video, it looks like the coil may be self oscillating or the transistor is fried, because the coil is supposed to be triggered by the wheels movement.
A lower base resistor value will stop any self oscillating.
Also, make sure to have a charge load that will take a decent charge initially, to prevent it back feeding to transistor and frying it.
peace love light

I did the test on my transistor and it still kicks away the magnet. I tried again with another transistor i had and got the same result when the trigger is disconnected from the pot. I bought a new transistor, part number mj15004. They didnt have the same one i was using before. I did the test again and nothing happened. There isnt even a spark when i attach the emmiter to the negative of my primary. Is this transistor non compatable with system? I was certain the new transistor would solve my problem

[tachyoncatcher]

PnP

@Gpilot,
That is a pnp transistor. Your drawing calls for a npn transistor. You could use that one with some rewiring, but you will be better off using the correct one. At least you know the problem AND solution.

What is the part number for the right transistor? If i cant find one i will order it. I have seen people use different types, but any sugestions on what you all are having success with?

[tachyoncatcher]

Here you go

This is what I use.
5 MJL21194 Transistors used with Bedini Monopole Energizers.
Has worked well for me.
