[sdiy] My Joystick Design

[Rhen, Kris]

Ok, please no laughs.  I'm still a bouncing baby newbie, but I bought some
of those MECI joysticks and want to make some controllers out of them.  The
first one's schemo is here

(one axis only shown) Its fairly simple.  Takes either a constant voltage
(from the +15v source) or some input switched at the jack, so it either
functions as an attenuator or a pure CV source.  The input is ranged, then
the joystick moves from 0 to the range.  Then, there's an offset pot that
takes it +- about 5v.  Both axes are the same.  Any
comments/suggestions/optimizations?  I'm particularly not sure on the
input/output impedance thing.

The other design is the same but the joystick acts as a reversible
attenuator (I'll show that one later). Thanks all
KRIS
