Thanks, gyulasun. I see you're a big poster here, maybe you can give me some pointers. I want to build one of these motors but there are many different designs and principles being proposed. Any thoughts on which one would be the best bet to get started with? Any advice appreciated...
Thanks, Mike

hi springfield, I suggest you start with a simple bedini sg (school girl) monopole. bi or tri. There is a simple tutorial here http://www.youtube.com/watch?v=zJySgeSpJpQ parts 2 + are easy to follow. You can study it more closely in its simple form at bedini monopole3 forums with other beginners. Once you understand the basics you can move on to more complex configurations.

@ Ren:

I too am collecting components for the Bedini SG.  I have watched the video tutorials (especially introverterbrate's) on youtube posted from several folks,(very well done by the way) and have a good basic understanding to get started.  Just one question that I can not find any reason for but keep hearing repeated and this is the type of magnets.  I have a mess of very powerful neo's from other experiments and they would fit well on my VCR motor spindle I am using.  Everyone says to use the much weaker ceramic mags "because we don't want too strong a magnetic field" but they never say why?  I think the stronger the field, the more leeway we have in the positioning of the coil, the stronger the pulses would be...etc.  That, of course, is my uneducated beginner's opinion which I am not inclined to put much stock in. So:

Can I use my neo's?  Will it work with them at all?

Why don't we want a strong magnetic field?  Could we not just raise the rotor above (away) from the coil to reduce the field strength?

Sorry, I said one question but these are all related questions.  Thank you.

If anyone else has any opinions on this I would be glad to read them.  Thank you.

Neos will work, they tend to over saturate the core which can  increase amp draw or just make for harder tuning. I personally have made high speed rotors with vcr and hdd hubs and both went super fast, but just didnt perform as well with charging. What you have to realise is the magnet is the source of induction for the trigger. You have heard everyone say you want the fastest switching time possible? Well its much easier with a weaker magnet. This is also why every one has different results, all magnets are different hence all inductional properties are different. I have a tiny HDD energizer which has tiny 9mm x 9mm x 3mm mags that works great.
