Hello,
I just built my very first bedini motor. I have been watching the videos for months and have seen many different types. I followed the instructions on youtube extactly (although I am new to schematics, and transistors and stuff). While I am new to these circuits I am not new to signal path. I am an audio engineer so hookups come easy to me. I have checked all my connections about 4 times over so I know the circuit is wired right. I have not given up the idea that there is a short somewhere, but it seems my motor isnt doing much of anything on or off. Oh and by the way I work at a radio shack so most of my parts come from there. They have almost everything. These are the specifics of my motor, and what it is doing:
I am using a rotor built from 2 cds, on a CD rom bearing ripped from a cd rom drive. It has 4 ceramic magnets glued to it width is about an inch and a half all magnets have their north pole facing out. catalog number is 64-1877 at radiochack.com. for resistors I am using one 100 ohm resistor and one 330 ohm resistor wired in series (430 ohms total) which is then linked to my pot, which is 5000 ohms. I am not sure if that is too high I checked some forums before I bought it. One last thing about my circuit is it is all wired to a barrier strip so that I can just screw things in and dont have to solder as much. Oh and lastly the coil (which took especially long to compose) is made up of about 700 winds using 22 and 26 gauge wire. The two wires were wound very close together, although it isnt perfect. I have the top of the coil near the magnets.
Problems: The wheel spins...just not on its own. I have 2 14 volt drill batteries one dead and the other is fully charged. I tried bypassing the dead one, but it didnt help.
when hooked up the transistor is usually buzzing...Is this normal?? I also had the neon bulb light up as the transistor is buzzing, but very dimmly flickering. all this while the wheel is NOT spinning. If I spin the wheel manually I will hear a shift in the pitch of the transitor buzz. I also touched the collector and got shocked with about 14 volts. Any Idas about how to fix this thing, I can get some pics if that helps.
