As an extra bonus question, my sensor is going to be an old phonograph
cartridge.
And you *need* to use that phonograph needle?
Analog Devices sells cheap MEMS-based accelerometers (e.g. ADXL202). You
could even use two or 3 axes. The output a 5V square wave whose duty
cycle is proportional to acceleration.
