@Woopy and  i_ron, really cool looking builds.

Good stuff

@Mags Really nice video and rundown.
I also have used Ceramic Skate bearing in the past, but they soon knacker up when you hit over 10'000 RPM LOL. Good for low revs though.

Cheers

My bobbins are ready waiting for the wire to arrive.

Hi Toranarod

How thick is the skin on the inside?

Best to get the wire as close as you can to the ferrite.

Nice looking bobbin though

Cheers

We have seen self runners come and go . there have indubitably been hoaxes . The notorious Mylow . and likely Mike as well . As time goes on , more experienced people are using ever more sophisticated techniques to analyse these videos , using methods that James Bond would envy .There are people who come on these forums that refuse to entertain the faintest possibility that OU exists . I can never understand why they spend their time here . As it happens , I don`t believe in Fairies . But I don't spend all my working hours searching pro-fairy forums debunking the believers . Every day we get a little nearer to the truth . Look how long it took man to learn to fly . We have reason to hope that this will not take as long .
PS every time people show pictures of coils . I think of my little grandson`s favourite nursery ryme , "Wind the bobbin up "

American Made muller might be using these things:

http://www.magnet4less.com/popup_image.php?pID=236I=0 3/4 by 1/4 magnet for top and bottom

Since it appears that people are not really replicating but instead making there own design now I to find some equivalent to the litz wire here in the US...

Sorry if this has been covered before, but so many posts on this.

Trying to get straight in my head the firing sequence here.

We have two Hall sensors, one fires Coil Pair A and the other fire Coil Pair B.

I take it the coils repulse the rotor magnets, so what are the best positions?
