Muller Dynamo

Todays progress
We Its time to wind the coils. Oh fun and joy. 18 coils 

when its all assembled I will present a full specification list and we will see how close to Romerosuk I have been able to build it.
there where some parts I cloud not get. hope its close enough.

@toranarod: I admire your build and would like to know where you got the nice bearing?

See the attached copy from your photo where I marked the bearings I am interested in. May be you have time to explain how you intend to mount your disk (carrying the magnets).

Greetings, Conrad

@plengo,  you are messing with my scheme of saving all the pages here as they keep changing and numbers change.     Oh well good riddance to tommy troll. 

@all using solderable Litz wire as most of us probably have got if we ordered Litz.  Based on koneheads good info I'd suggest if you already have solderable Litz to put extra effort into making a solid build as vibration free as possible.  I'm sure most replicators at this point are not looking to build a long term power solution out of this first build but rather a proof of concept so it may not be that important but it would be nice to make it last. 

@conradelektro,  I can't say for toranarod but it looks to me like either a hard drive bearing or CD drive bearing.  Those are fiairly low friction but I have had some concern if they will hold up under the much heavier weight of the acrylic rotor and magnets.  I think Romero said he used a hard drive bearing.

Here's a DC to DC converter I build. Maybe some of you will find it interesting. You may see a video about it here: http://www.youtube.com/watch?v=sqW2mbV3aDs and the schematic below

Yes this is much better for a power supply
there is more control over something like this.
looks like a good circuit.

here is one I use and will try on the Muller.
I used this on an Adams motor I built.

That`s pretty cool. I use this configuration as an inverter in my bike & scooter ignition I build. It raises voltage from 12 V to 250 V needed for capacitor discharging ignition.

The bearing is from a WD hard drive. Old hard drive bearings are not normally not strong enough.  This one I found in a WD as in the photo below  has a very robust construction. I am always looking for this type at old computer junk sales. 
easy to get out and very easy to use. I have used this particular type from the WD model On much bigger pulse motors before with no problems. 

I will post the serial number?
