The module was controlling:
- the solenoid valve positioned above the cup (and connected to a tank containing milk)
- an infrared motion detector, positioned below the valve, on the droplets' way
- the DSLR
- the flash
Most of the technical work consisted in programming the module, so that it would allow for 2 consecutive droplets to fall within about 80ms, trigger the DSRL just after that, detect the droplets falling next to the motion detector, and fire the flash bursts accordingly.
At first I tried all of this manually, but it was a real nightmare, especially without the solenoid valve to launch 2 droplets at will... you should have seen my tries using a perforated yogurt pot in a dark room :-)
Overall, it took me about 2.000 tries, distributed over 4 week-ends, but I'm a slow guy!
