Re: Triggering methods

That's really interesting, thanks. I'll take a closer look at that info over the next day or so. When I started working on this project, I did it for a couple friends who have a little photo booth side project. Using an Arduino with all the cameras connected to the same input line worked just fine to trigger a pulse simultaneous, but they wanted to do more. They wanted to be able to do linear sequences too.

The easy way of doing both on an Arduino means still firing them several microseconds apart at best, enough elapsed time such that if a fast strobe light were plugged into the circuit and was fired first in the array, the light would change by the time it got to the end of the array. So I built a more complicated circuit using a different chip.

The device does more than just triggering a pulse simultaneously. It also allows you to set them off in sequence at whatever interval you want, or individually on an ad hoc basis if desired. It hit all the needs my friends needed to get going, and since then I've worked on it myself, building the iPhone remote control app. It is set up to be portable and run on 5V power, so you don't need to have it plugged into a laptop to use it.

I'd love to take a look at your research paper when it comes out.
