Universal "GB60Board"

Experimental driving circuit for a synchronous harddrive motor
HD-motor Some days ago I played around with a killed harddrive's synchronous motor which usually turns the harddrive platters. I asked myself how the driving circuit would look like to bring such a motor to life.
As it sounded like an interesting experiment, I've developed an experimental driving circuit to bring the motor to it's limits. Read more under the title link (incl. video of the experiment)...

Server misconfiguration!
Due to a misconfiguration of my web hoster, the scripts of my homepage aren't working fully correct. I am in contact with my web hoster to fix the server installation and to bring this site soon completely online again.
Sorry for the trouble!
