Photography Laser Trigger

[JonnyFGM]

Thanks for everyone's help with this one

I decided to just jump in at the deep end and do it lol, decided to go with the missing pulse idea with a phototransistor. Initial prototype is done, so far only the triggering feature has been implemented, the delay, counting etc is to come later.

Anyway here it is in the wild, well in my back garden

oh and another question.

The poles they are mounted to aren't the most sturdy, and as a result the laser keeps moving and not hitting the phototransistor.

Is there anyway to increase the size of the receiver bit? I was thinking something along the lines of a bunch of fibre optic strands in a big circle with the other ends focused on the PT?
