To start we'll need
2 thermistors - 50 K or 100 K ohm are
best for most applications.
Some 2 conductor wire - speaker hookup
wire will work fine.
Pins to fit the sub D connector or a male
15 pin D connector.
Soldering equipment and heat shrink tubing.
Get the parts ready.
Radio Shack didn't have a 15 pin sub D
so I spent $1 for a 9 pin and only used the pins. The part number
Attach one wire from
each of speaker wires together, solder them together, then solder the pin connectors
Some heat shrink tubing
finishes the pin end.
Now solder each thermistor to the other
end of the speaker wires.
There is no orientation to + or - for
Heat shrink tubing completes
Twenty minutes and
the hardware is complete.
I wound the speaker wire around a screwdriver
to give it the classic tangled phone cord look.
Shut down the computer
and attach the pins to the #1, #3, and #6 holes on the gameport (sound
card) D connector.
