working a real gauge without PMSys.

(This works only with electrical gauges)
Wired this way, the pointer moves from zero to full when the pot is rotated from zero to max.
The pot can be preset so that the pointer goes to a target value when power is applied and reverts to zero when power is off.
Can be used that way for brake pressure with a microswitch on the brakes pedal.
Now the question !!
What kind of little electonic circuit could be used so that the pointer would creep slowly to the target value when power is applied. Could be used for Hyd pressure on engine start, or APU spooling up, or temperature going up etc... No link with any software and sort of eye candy but good enough for secondary systems and dirt cheap!
Any idea?
I know who has the answer :)
This is a good one for Mike Powell :) :) :) I'm willing to bet he has the answer :)
