In another thread there where an interesting link to an Java application for calculating a lot of measurments.
What I put into the calculator might be wrong, but when I look at it it looks pretty much allright, please corrcecte me here :)
A thing I cant see why, is the spacing betwen the secondary turns, it is not so big at all, and my wire can have been so heavy either. The tool on the site gave me 1896 turns of wire. Thats a bit more that i thought it was.
On my secondary the wire it stands diameter: 0.2mm , but I think it is a bit more with insulation in count. It says the resistance of the secondary is 230 and it is actualy 235 so that is no far off.
