just finished my first bedini energizer and already problems :(

Yes, please post a photo of your setup!

The Bedini motor system works on relatively high-voltage spikes. Simply using smaller transistors and less wire and LEDs instead of neons... you are not making a Bedini motor any more.

The 2n3055 is really cheap and is the recommended transistor to use. Some other transistors that you can find in old CRT TV circuit boards are also good to use, but you should be able to get hold of some 2n3055s easily enough, they are very common. The transistors in your JT kit won't handle the high voltage spikes that are fundamental to the Bedini system, although the metal-can 2n2222a transistor can work well in high-current JTs with spikes of 50 or 60 volts. Any reasonable Bedini rotor-coil system will be making spikes in the hundreds of volts, though, so the smaller transistors don't have a hope of surviving. Not all 2n3055s are created equal, either.... try to find name-branded ones, not generic unlabelled Chinese fakes. The neon is there as a kind of "90 volt fuse" that fires when the spike from the coil exceeds its threshold voltage, and this protects the transistor from these HV spikes. So you can see that an LED would not do the same thing, once you got the coil making the spikes the LED would just fail open and then the transistor would probably die in short order. No pun intended.

I know you are getting tired of watching videos.... especially mine.... but here's how I made my first Bedini monopole motor/charger, when I was helping someone else get started. (If you search this forum you might find that old thread... we finally got his working.)

There is a better way, IMHO, to make "bedini-style" pulse motors, though, that MileHigh first suggested. We call it the MHOP, and it does everything any Bedini motor does, in terms of charging external caps or batteries, etc. but it's a little more complicated electronics project, probably not for raw beginners, although it's really not that bad.

ETA: The 1n400x rectifier diodes are tough little buggers. The 1n4005 is fine to use instead of the 4007, even though you can get spikes that exceed its voltage rating, it generally can take it since the spikes are so short duration.

Ah... I see in the photo up above your post that the builder is using a lower-voltage system with a TIP122 Darlington transistor. My supplier sells these for 75 cents each, they are common as dirt! And the builder uses a LED and capacitor in place of the neon in the higher voltage system. You might consider trying the circuit he used up above.

Thanks for the suggestion tinsel. I have since bought a 2n3055 and a TIP31 and still can't get anything spinning but did finally get around 20 Milliamps output spinning by hand. I also scrapped a magnetic window alarm for a reed switch thinking that could be the culprit and still no results. I have since then re-engaged joule thief and ran across the re-emf circuit by Rene. It seems to be doing what I was looking for as far as charging and desulfating same as bedini circuit and with less materials and space. So again thanks for the input and I enjoy your videos.
