Muller Dynamo

ChrisC, I remember Romero saying that it is important that the rotor should be thick enough so that it should not bend. Do you think your rotor will be stiff enough after the magnets are added? Thanks for the info so far.

The rotor plate is 8" and the stator plates 11". From Tab Plastics. These are precut circular acrylic plates used for wedding cakes tiers and that's why they are much cheaper. see: http://www.tapplastics.com/shop/product.php?pid=140&PHPSESSID=20110517203131322248093

I had to drill the tripod holes as they are not critical but took 4 hours; all I had to do is to make sure it's close to 120 degrees. The 8 magnet holes on the rotor are cut by Tab plastics from the stencil someone generated right at the beginning of the thread. Those holes cost $30, I think. It's NOT CNC and they have 1/8 or 1/16 tolerances(?)

Magnets I've ordered from http://www.magnets4less.com.
30 Neodymium Magnets Disc 3/4 in x 1/4 in Strong N42 (ND045-1) - $46.50
7 Neodymium Magnets 3/4 in x 3/8 in Rare Earth Disc (ND046) -       $20.23
Shipping                                                                                     $12.18

Hope that helps. Tab Plastics will do online orders and you can give them all your requirements (assuming you're in the U.S).

cheers

@woopy : what is the sampling rate of a "low budget" multi meter ? And how strong is the interpolation "function" in them ? Is it possible due to the value update feature a simple multi meter fails at measuring the correct values at 950 Hz ? Probably not relevant to the issue, but as some smart guy once said : 98% of the so called OU devices are simply a missinterpretation of the measured results.

@dave45 : ofc it should be the moon phases. That is how the muller generator achieves that balance to not get a lockdown position.

Congratulations Ben - 68 years young!

i'm starting to catch up 

looking forward to your build videos - we need more people with your keen ability and humility

yeah, you correct, Tudi, at least one True RMS Multimeter among others is minimum before talking out
