This version is enhanced by real hardware inputs:
2 potentiometer knobs control speed (movement interval) and current program.
Additionally Program 0 adds a special manual mode to control the servo positions directly with the knobs.
Now the system is really useful as Live instrument, because you can inter-act directly with the music and change the posistions or programs matching to breaks and changes in the music.
An old PS/2 keyboard cable was used to connect the mirror “stations” to the controller box.
The cable length can be increased by plugging more PS/2 cables between – they are/were common for KVM monitor/keyboard switches.
Now the mirrors and beamers can be placed far away from the “remote” controller box, which can also run autonomously without computer connection and just an external powerplug.
For live visuals, we still use the software interface to display the current values like angles, speed and program settings,
but the knobs as a real hardware interface ‘feel’ much better than keyboard presses on a netbook 🙂
