FW: another modest proposal...

[David Halliday (Volt Computer)]

Actually, Hall Effect keyboard sensors aren't good for analog output
since the sensor has a built-in schmitt trigger and the output is either
full-on or full-off...

I have *not* taken a keyswitch apart so there may be some way to extract
an analog signal from it but I do know that the output is straight
logic-level stuff...
