just finished my first bedini energizer and already problems :(

[capacitor70]

I tried to make an electromagnet (to just get my first motor to spin) and I used 26awg (27swg) enameled copper wire , 350' onto a ferrite core.  The resistance I measured was 20ohms.  But when I run 12V through this , there is no magnetic field.  The copper wire just gets hot.  Any ideas?

Coil works as electromagnet without problem, Similar type like yours with ferite core and large number of turns (more than 200 Turns)

Coil shows some times N pole, When connected to DC, some times it atracts the magnet S pole. with Iron or ferrite core. 

Soon, I will make 1000 turns bifilar coil...

    Motor is Running, with two relay coils,

current taken is 2 to 3mAmps at 12Volts

With relay coil it gives 2 to 3V for transistor drive.

Hello all,
Another new builder here that was amazed by the possibilities of the SG and SSG. I have tried after watching many videos and reading countless forums to build my own monopole as close to possible to posted bedini schematics on a vcr head roter. The exception is that I dont have space and cash at this time for the actual bicycle wheel kit and all parts listed aren't readily available. Ok for the lack of schematic knowledge I have I am slowly learning them but from the many I have researched they are all basically the same as this YT video http://www.youtube.com/watch?v=ttY7yLXZSpo.

My build is around 140 turns using 40 feet of 22-gauge run wire and 40 feet of 26-gauge trigger wire on bifilar on same spool it came from in radio shack 315' magnet wire set http://www.radioshack.com/product/in...ductId=2036277
The magnet setup I have tried on hard drive using the curved neo's found inside of the hard drive using 1 epoxied on each side of disk as well as another setup consisting of vcr head with a cd-disc glued to top with 4 1" rectangle magnets from radio shack http://www.radioshack.com/product/in...=2103429spaced evenly like a + and a third setup on another vcr head with 4 tiny button neo's http://www.harborfreight.com/10-piec...ets-67488.html that i figured from the compass method have a north field while laying flat depending on which way it is filpped also in a + configuration.
Ok now free spin of the hard drive rotor is around 20-30 sec while both vcr head rotors will spin for 60-90 sec.
Here is where you guys are going to yell at me. Being on a budget and radio shack not having in stock the 3055 transistor I bought a combo pack for joule thief build consisting of 5 each 2n222a, 2n3904, and 2n4401. http://www.radioshack.com/product/in...ductId=2062586. figuring this could be my main mistake can anyone tell me why these wouldnt work on a small scale such as recharging rechargable batteries aa, aaa, 9v with 6.2v lantern battery as power source or I have various cell phone wall worts that may also be power source depending on reccomendations.
The diodes are another part that I couldn't replicate but I think should still work. I did get the 4001 right but radio shack didn't have the 4007 in stock so I got a 4005 http://www.radioshack.com/product/in...ductId=2049728 instead to go in its place.
Another scolding point is I can't find a ne-2 neon anywhere local so I am trying a 5v led just to see if I am getting a spike from the Emitter to Collector with charge battery disconnected. The LED is lit seemingly from the power source. I then attached DMM to those leads and nothing happens when I pass a magnet by the coil at any distance, it stays same voltage as power source. I have tested the coil for shorts used wire clothes hanger core and air core and I get nothing either way. I have set my circuit up according to all schematics that seem to be the same as youtube video and forums that I have read and I can't figure out where my problem is. If this isn't enough info I can take a picture of my set-up and post it here. Let me know any suggestions please.

You are going to need an ne2 neon bulb, if you don't have it just eliminate it (not a great idea long term).
There are those very small inexpensive neon nightlights that are just a 47K or 98K resistors in series
with a ne2 bulb. Carefully cut the plasic off the bulb, then cut the ballast resistor off the
the plug lead. *LEDS will not function correclty for the ne2 in the monopole circuit*


Just a hint, The SGS motor circuit was designed to minimize component count, therefore
the correct functioning of the circuit *depends on parameters of the active transistor*. It may
be possible to add components to adjust parameters of the others, but the easiest thing is to get
a 2n3055 or an NJE direct equivalent. Advance Electronics would be a good source
or any local TV electronics repair shop should have one.

I understand the need for the neon bulb in the larger 12 volt applications but again I am going for smaller scale if possible because of the parts I have on hand. I was figuring if I am only trying to charge 1.5 volts max a 3-6 volt led in plave of the ne-2 lamp may be sufficient but regardless of that I still can't get  said 6 volt neon to light up when connected to emitter and base. I can't understand how soo many people are running monopole coils as small as a fingernail and getting enough voltage to charge 12volt batteries and still getting at least 65volt BEMF. I dont know if my transistors are having a negative effect or my coil just isn't big enough though it should be plenty big to give me at least something when passing a magnet by it.
