Analog accelerometers are pretty inexpensive
(www.analog.com, ADXL-301 i think). You'd need an ADC
to use them though; i suppose you can find a
microcontroller board with built-in rs-232 level
shifters. Getting the ADC shouldn't be hard, since
many cheap mcus (PIC, fe) have one, two or more.
Analog devices (same url) also has a slightly more
expensive digital accelerometer. It's based on the
same analog device, but has additional logic, and
communicates through PWM, but i don't know if it's ok
to plug one data wire directly in the serial port.
