Thanks for all the suggestions. I had trouble getting the crude
analog-to-digital (on/off) circuit to work, so I have decided to use an
Arduino Nano (http://www.arduino.cc) that actually has 10-bit analog
inputs. So, I will be doing the pulse counting on the Arduino, and output
interval values through its USB-serial interface, which I'll read out from
Perl or C or something.
This should all work from FreeBSD without any problems!
