Hi Paul:
I'm presently adapting a chrony chronograph because I want to use the
triggers for timing and other purposes. They've spent a LOT of
engineering time to get proper triggering, and the triggers can easily
be pulled off
However, since we are all nuts here, adding a GPSDO coulnt' hurt.
(Usually you shoot outside, so access to the sky should be easy!) Then
you'd also know position, which could be useful in accounting for
numerous other thing like coriolis acceleration, gravity due to
elevation, and gravity

Hello Folks
I have been looking at bullet chrographs and wondering if I could get the a usb
module to do a interval measurement and display on my laptop.
on a yet to be discovered module to calculate the time interval between the
pulses?
The bullet travels at approx 1050 feet per second.

Hi Paul,
See http://leapsecond.com/pic/picpet.htm and contact me offline for the USB
part.
What do you use for sensors: acoustic, optical, seismic?
