Servo Pulse to voltage converter.. Mini SSC II

[Jon]

I have a motor that requires a control voltage between 0-5V.. Ov=stop
and 5V=full speed. I'm using Mini SSC IIa and need to take one of the
servo outputs and create a voltage?

Is there any off the shelf device that will do this?

Can I just integrate the pulses and offset and scale the integration
with an op amp circuit?

Thanks,
Jon

I've tinkered with a kronosrobotics servo control chips and ran a
servo control output thru a diode to a 1mf capacitor. I was able
to connect this to the base of an NPN transisto to the + side of
the capacitor, which inturn controlled an LED. I could see some
change in led intensity when changing the servo position full
range. You can connect a meter and see some voltage change. Below
is a page where I'm using a mini ssc ii as a pan/tilt webcam
control.
