No probs FRC, I think the SSG bipolar kit is for a self runner conversion, a NSNS alternate pole arrangement, i might be wrong i'm not familiar with that. I think you might want to stick with the monopole setup for now. The bike wheel is good, I will try to take a short video tomorrow of some points of interest on my very rough one, I made a simple wooden frame for it, that I will modify, it's not finished yet and i've been using it for ages. But it is very functional.
I highly recommend that you get the bipolar circuit. You will get 2 of the MJL21194 and 21193. So you can use the MJL21194 for the standard SSG set up and then when you are ready to experiment with the bipolar switch you will already have everything. I would also recomend that you purchase a couple of Hall sensors at the sametime so when your ready to use those you wont have to reorder and pay for shipping. Dont waste your money on the 3055 transistors they blow too easily, and if you only use 12 volts on your input chances are you will never blow the MJL's.

P.S. You can use the bipolar switch on any of the SSG kits, I prefer to use it on my 3-pole kit. I bread board it so I can easily change resistor values.
Thankyou to all above who replied. Your posts are very helpful. Seems the more
I learn, I realize the less I really know. There is a lot more to understanding the
SSG than I thought there was to begin with.
Not enough current through base to turn transistor on
Hello everyone. I have just finished building my first ssg and i need a bit of help. When i place a voltmeter across the trigger coil and spin the rotor by hand, i only get .2 of a volt. I am using neodynium magnets mounted on a hard drive as a rotor. Is it possible that my magnets are two small to trigger the base ? Or am just getting the whole thing wrong. I have checked the cct over and over to see if it's wired correctly and all components are working.
I understand that this tread is fairly advanced. Even if someone could point me in the right direction.
Thanks.

Reason: More to add
i too am starting with this SSG stuff, see my posts in the "Bedini Schoolgirl" threat.
I also use neo's (4) although that is NOT recommended because they could be to strong and saturate your core.
I measured my triggercoil voltage when turned by hand, and it reads 0.4 V in the AC postion meaning 400mV ac.
The scope shows a RMS of 432mV, and 1.32V pp.
All offcource depends of the distance of the core and the magnets and the trigger resistance used etc., so perhaps you could give some more details on what you are using (transistor, diodes, coil dimensions, core material, batteries etc).
Also i recommend to read this document (thanks Farmhand) which has a lot of usefull info:
Hi. Just asquired the plans for a Bedini generator which I am excited about. I'm reviewing the design in order to plan out the project. Plans specify Grade 3 Ferrite magnets; which dimensions translate from metric to roughly 2"x2"x3/4". After a quick web search I noticed that there is a more powerful type magnet than the ferrite type, which I can get in blocks of 2"x2"x1". One source offers Grade 8 ferrite magnets. The plans did not explain their choice of magnets. I assume that the size of the magnet relates to the size of the coils. Does the thickness matter? Would anyone care to respond with some thoughts on what magnet to use. Any info on a source would be appreciated also. I'm an electronic hobbyist, with some training, who has been an amateur radio operator for many years. I'm confident in my ability to complete this project with some guidance from the gurus. Thanks.
Pardon my oversight in not specifying which generator I plan to build. I bought the Magnets4Energy PMG plans. The design specifies three main elements consisting of a stator and two rotors, circular in shape, each about 1' diameter, aligned concentricly around a wheel hub assembly. The two rotors, located on each side of the stator, each with 8 magnets, rotate, while the stator, with 6 coils, is stationary. The magnets, oriented on the opposing rotor plates, so as to attract each other, rotate over the roughly 4.5 inch square coils. The design, which I suspect is old, specified Grade 3 2"x2" magnets 3/4" thick. I located 2"x2"x1" neo's which I am considering using. What will that do to the design, if anyone knows? Thanks.

If it is a SSG Bedini project you are building (like mine) you don't want to use neodymium magnets, according to Rick and John. For various reasons, they specify that. Stick with ceramic grade. They are cheaper anyway. Best way to learn about the radiant chargers is to stick very religiously to the SSG circuit as outlined by John and Rick, learn as much as you possibly can (by not deviating) - then - afterwards get experimental. They have really simplified things to the point where you will get trained in the basic parameters, first... seeing what the circuit does, and should do, in it's most basic form, allowing you to understand the fundamentals before moving on. They have plenty of advanced projects (as do others here), for your future playground. The way I see it, is, if you can get a SSG to run at unity - or very close to it - you've really accomplished the initial goal. A person could spend an endless amount of time, money and brainspace building variation after variation that ran at 60-80% of unity, and essentially learn nothing. That's how I personally see it, anyway. I think that's Rick's point, and it makes sense, really.

Has anyone seen my Bedini Ceiling Fan that pushes the warm air down, and charges batteries as an added bonus? Me neither. 'Bout time I made one!!!!! :P

I'm no authority on the system, I've never built one, nor have I heard of anyone building one, BUT
a lot of scams are out there.
I'm not saying that it is impossible to make a circular shaped motor that propels itself by magnetic force alone... however... the average home needs about (min) 3.5 kilowatts. That's a lot of drag. Your perpetual motion machine had better have some good torque for that. It's tough to create that with a 25 km/h wind, and 18 ft blades... your gonna do that with a stack of perpetually moving magnets? Good luck on that one. MY bet is, if it were accomplished. It'd be worthy of more than an ebook marketing plan!
Why not consider a Bedini project. At least with a Bedini project you have a solid community of experimenters. No horribly unrealistic claims like "Running Your House" -- My thoughts are, if there was a permanent magnet motor, sold by ebook plans, that worked... as in "really worked" -- it'd be an info-storm - it'd be so widespread and making news RIGHT AND LEFT.
Worse thing that can happen with a Bedini project is you build it incorrectly and learn how to correct it so it charges batteries. Any way you look at it - it WILL do something beneficial. You don't see 500 people a day claiming they were "ripped off" by John Bedinis technology. Even if you cam to the conclusion that you didn't think it was worthwhile, the parts you've purchased are useful for hundreds of similar experiments; and another interesting aspect is, despite whether or not it harnesses free energy it does charge batteries. You might just find something "spinning around" that can be adapted into a battery charger, in addition to what it is already doing.
This is another real cool thing to build, that I personally, totally believe in. I am currently involved in building a pump using this technology:
