Bernd;

IIRC, the RC servos take a 0.5ms to 1.5ms pulse input
at about TTL levels.  If you're really strapped for
power, you could always power it down until the
reading needs to change.

The pointer could be something simple made from
pastic, like a disk with the 'needle' drawn on with a
marker.  Naturally, once you're convinced it will work
you could fab up something more elegant.

Sounds like a good match for your application.

Disclaimer: I'm not into R/C and going from an
increasingly faulty memory. . .
