Puppet III Board

Joystick Controllers
The Puppet III is designed for use with many standard Analog joysticks, and will usually
operate well without any controller board modifications. Try the joystick first, before attempting to
make any modifications. Many game joysticks have a nominal resistance of 100k ohms per axis.
If you find that the servos are (a) not moving the full 90 degrees, or (b) they move 90 degrees
with significantly less than the full movement of the joystick, then it might be that the internal
resistance of the particular joystick is significantly different to 100k ohms.
To check this, remove the joystick from the Puppet III and using an Ohmmeter, check the
resistance between pins 1 and 3. Move the joystick until you read the maximum reading. If
it is significantly different from 100k Ohms, then you can adjust the dynamic range by
changing out resistors R1 and R2 ( lower left-hand side of the board ) for standard values
closest to the measured maximum resistance.
Joystick Configuration
Adjust the two slide tabs located on the joystick ( top or bottom )to fine tune servo motion, and
to control servo shimmer and shake. These slide tabs will need to be adjusted as the joystick
handle becomes warn or loose, or will not stay centered.
