As long as the material being fired is massive enough, a CDS or light interrupt circuit works. Pretty simple to build, and the switching for how long each coil stays active is pretty straightforward too. Typically, however, something like this has a meter or more in barrel length - and that only maybe punches through a #10 can on a good day.
I believe there are videos of the longer pipe models kicking about on youtube.
