You're not understanding Roy.  Real instruments are driven by 400Hz AC 
Synchro motors.  What Mike has designed is an apparently inexpensive 
method of driving a synchro from a digital signal.  Prior to now the 
only DS converters I've seen were in 18 pin DIP packages and cost $900 
*Each*.

This means that you put one of these little doohickeys between your real 
instrument and your computer, add some wire magic and viola!  real 
instrument in the cockpit. :)
