Why pay £200 for a laser trap flash trigger when I can make it at home for nothing?!  All I need is two small aubergines.... and an Arduino, a Light Dependent Resistor (LDR), a 10k resistor and a laser pointer...

The analogue input pin A0 reads about 200 without the light in a dimly lit room and about 600 in strong light. Over 1000 when hit by the beam as in the pic below.

So the next test is to get it to trigger the flash when the beam is broken (and the input value falls below say 800).  If that works, I'll see about adding a knob and a simple 4 digit display to adjust a delay between detection and flash triggering..
