Some sort of sound emitting device would be good, although if its a windy day...
As long as you have a rough estimate of the flight time, doesn't really matter how the smoke is triggered, in fact you want it to last long enough for
you to get nearer the estimated impact zone.
Even a simple fuse would do, although you'd want a way to easily abort if required

I agree that cake mix is probably not going to last long enough to be significant...

Oh no...
.PNG coat hanger... did you just find that on google images ?

The little "icon" size option is convenient

Saefroch could get about a 35s burn time from one of his cakes and total flight time of the projectile would probably be around 25s give or take. With a spotter about 1km away from the estimated target zone but at a much higher elevation, I'm sure they could narrow down the zone to about 100m^2 at the least.
A fuse sounds like a good idea but how do you go about igniting it? I can't have a 1.8m fuse coming out of the barrel and I wouldn't trust the fuse igniting/staying intact if I drilled a hole through the sabot, poked the fuse through and hope flame front would ignite it. Unless there is some other way?

At first I thought it was spam, but that is a great idea!
All you have to do is vacuum-pot the internals in epoxy to G harden it some.
Still too big (I can tell even without having seen the circuit).
To fit in the MiniBoy it can't be wider than 14mm.

Even if you get rid of the threaded rod and glue everything together?

Yup, even an AA battery wont fit (perhaps the diameter is actually less than 14mm, I can't remember). Something the size of a sim card but longer would probably work great.
