Time-Nutties,
how about using a small uC (PIC/AVR) clocked with 100ns instruction
speed. Start = 1PPS from GPS, Stop = 60 Hz Edge? Use internal capture
hardware to count processor cycles in between.
Send output once per second via FT232(USB) to host PC.. alternatively
store locally on SD card..
This could be a tiny add-on card in main-powered GPS setups..
Sorry for not jumping on the soundcard-software approach.. I'm a
hardware guy and my programming skills suck.. :)
Regards,
Achim
