Gpilot,

Where did you go? Did you get a good transistor and get your SSG to work. If you can't find the MJL21194 you can also use a 2N3055. The MJL is a better transistor and is stronger but the 2N3055 will work if you can't find the MJL21194.

I was given a BU 2508DF PHM0001 b4 transistor. I am.in.italy and there is still.a.language barrier. This one doesnt seem to work either, so.i just ordered a few that u recomended. Wikl keep u posted.

Here is a link to youtube that shows the progress. I built a new circuit with all new componants. It still wont run. When i hook it all up, you can hear the electricity going through the coil. When i turn the pot up, the pitch of the sound is a higher frequency. You can hear the noise i am talking about, so turn your speakers up. Thanks mates.

It's probably self oscillating. If you want the rotor to turn you have to lower more the base resistance.

How do i lower the base resistance?

[SkyWatcher]

Hi folks, Hi gpilot, just experiment with different value resistors on the base leg of the transistor, as it is right now, your coil should be able to charge a secondary charge battery as it is in self oscillation.
Though you want the wheel to trigger the coil instead.
So lower the base resistance until you hear it stop oscillating and use meter or neon on output to verify it is not oscillating, as you would see a much higher voltage than input.
Hope that helps some more.

Self Oscillating

Gpilot,
It's self oscillating. What size is your pot? Bigger coils, require bigger base resistance. If 1k or higher, double check your diodes for correct orientation. If correct, switch the wires on the trigger coil. If all that fails, follow citftas direction for troubleshooting coils.

I got the machine to run! It only runs slowly at the moment, iwould estimate 60-100 rpm. I tried several different resistors, and tried putting a few together, but no effect. I cant get itto speed up when i adjust the pot. What do you think? Here is a video of it working.

Have you tuned it with the variable pot? (I think it is called
the 1 ohm test).

Core

Great! You got it running. Now the fun begins. Experiment, experiment.
Did you follow earlier direction and get rid of that solid core? Solid cores cause drag, heat and power loss on these machines. Also the steel L bracket behind your coil is not good.

After about 30 or 40 minutes it eventually slowed down and stopped. I have tried with all types of resistors from 100 ohms to 680ohms. The only difference i find is a change in the pitch of the sound. Still unable to keep it going, and speed it up. I have gotten rid of the solid core and i am using 2-3 dozen clothes hangers cut to theright length and super glued together. I will change the steel bracket, but the machine should run the way it is. I am going to buy some larger resistors tomorrow in the 800-1k range and see if it will start. When i disconect the secondary battery, the neon begins to glow. That is how it should opperate, but still, it eventually stops. I got another 1k pot as well, but no change.

Try to do a resistor as low as 10ohms and see.

[Gpilot]

I will get a 10ohms and 900. Hopefully one of the extremes will work.

Likely to be ordinary steel. I think you will find that they are useless.

You need to use the correct material which I reckon is swedish soft iron.
Welding rods should work well, if you hammer off the flux coating.

Magnetics

The steel bracket will effect the magnetic flux of the coil tremendously. Prolly causing it to sing like it is. I did some tests with steel plates on the south side of the coil for flux shaping and they caused the coil to sing. The purpose of the iron wire in the coil is two fold. One, to reduce the eddy currents. Eddy currents cause drag, heat, and power loss. Two, soft iron does not hold magnetism as readily as steel. If your circuit is working as it should, the magnetic poles of the coil will switch. Soft iron will switch easier than steel. I have had good luck with hanger wire. A good test is to remove the coil from the machine, after running it, and see if a pin or needle is magnetically attracted. If so, the core is retaining the magnetism. Not good.

On the subject of resistance. It depends on the amount of wire in your coil. The longer the trigger wire, the more resistance you will need. My current energizer uses over 2k base resistance. My pot is a 5k pot. To test your setup, give it a SMALL push. It should speed up from there. If it doesn't, your circuit needs work. Best to work on your circuit with a neon instead of a battery, so you can see if it is pulsing correctly. If the neon doesn't flash when the wheel is given a small spin, the circuit will not push the wheel as a motor. I'll say it again, get rid of that steel bracket! Glue a frickin piece of wood on the back of your coil to hold it down.
