Hi,
This is my first attempt at a web site.  So things,  
will no doubt be, dynamic for a while. Change is
the only constant.

A good article concerning Audio Taper :

A Mechanical Charge Pump.
It was a joke,.... really.  Then a silly idea,  
then it worked.  Who knew ?  The thought of
the sound of those screaming little relays
still makes me laugh.

I used a BS-2e to drive the relays with a
serial shift register latch, (74HC595), and
open collector array, (ULN-2003).

Measure Audio Taper.

I made this device to measure the
taper of Audio pots that are used in
the
OD-50s.

Here I am using a Parallax Basic Stamp
2 OEM to drive a Stepper motor that
rotates the
POT and then measures
the wiper resistance.  I simply use the
Debug command to create a crude
graphic in the Debug window.
