I'm copying/hacking existing designs for a velocity chronograph (aka gun chronograph). The plan is to control the device using a shrimp, with with two IR LEDs as triggers and a 7 segment display. The initial prototype will be two stand alone systems - the shrimp and the chronograph, but eventually it will be a fully integrated system.


I'll be roughly following this design: http://www.eevblog.com/forum/projects/airsoft-paintball-chrono/

Project diary/stages:

I have soldered up my first shrimp and tested it. I just need to fit a set of pins to attach it to a breadboard. I am thinking of designing a printed case for the USB interface dongle to give it a bit of protection. The next stage of this project is to acquire the chrono specific parts.

I've ordered most of the components and had an aluminium tube machined.
