An even better supply.  Voltage and current regulation if needed.

After answering to jorge message I realised that I need to post the answer to his question.
Can i use power supply?
Actually for the preliminary tests it is a must to use a power supply that stays stable and you know that the voltage is not going down and nothing is changing.

Stefan,

There seems to be a problem here.

Use FoxIT PDF reader, it is much faster than Adobe PDF Reader.

Hope this helps.

Thanks Stefan!  That will help a lot of people.  I know this thing about the Litz wire keeps coming up so I really really hate to ask this.  Not being in the U.K. I would not want to buy from Romero's source so I was looking at other places BUT I keep seeing that diagram someone uploaded and it's in your PDF compilation of the 7 x 0.125 mm wire.  Here is the problem and to me it looks like a typo.  Seven 0.125 mm wires in a bundle as shown in that diagram would have an overall diameter of 0.375 mm but the diagram shows an overall of 0.875 mm.  A 3 and 8 look a lot alike at a glance so I'm fairly sure that what you have there as 0.875 mm should actually be 0.375 mm overall diameter which for U.S. people is about 27 or 26 guage wire.  Otherwise we are looking at about 19 or 20 guage wire which is a big difference in size.  I'm fairly sure at this point it should be the 0.375mm or about 26 guage for U.S. builders.

Hmm,
I edited the posted wire size picture from User Arthus,
as RomeroUK said his total wire diameter was 0.875 mm.
Also you can see on his coil-rotor pictures, that the wire is almost a 1 mm
in diameter just from the look and comparison on these photos...

Hi,

Reading the thread with great interest. Wonderful job Romero! Everybody is waiting for such a breakthrough. Keep the good work going!
Concerning the ferrite rods there is a variety of sizes at Farnell including 6mm and 8mm in diameter:
