Here is a slightly fixed schematics, the sources of the firmware and the Eagle .sch-File ...

The circuit requires two supply voltages: +5V (named so in the schematics) and +35V (named <tt>vcc</tt> in the schematics).

Note, please: there is still no over current protection in the design.

If you like to use this design for your own purposes, feel free (and maybe, you want to let me know, especially if you enhance the design somehow). But dont blame me if something goes wrong. This design is working successfully in my basement, but, as mentioned before, it has still no over current protection (so, avoid short cuts on the bus wires). Furthermore, I cant state whether it is fully complaint to EN 13757 standard or not.
