Today I managed to encourage myself to begin building the power supply and not worry about blowing the fuses of our hackerspace again. The supply basically is right now a 2:1 transformer followed by a full bridge rectifier and a big capacitor. I think that the final design will have (a) switch(es) to set how many secondary coils in series shall be used.

Right now the circuit outputs about 180 V DC without a load. That's a multiple of the Voltage other peoples used in their design and I will see wehter I need to adapt to a lower voltage.
