Trigger Trap was a camera triggering product that was successful on its first Kickstarter, but failed on the second, and the company is now defunct. The full sad story is presented in an audio podcast called Inside the Lens which is produced by Don Komarechka, a Canadian professional photographer and total geek:

The product is actually quite simple, but everything you think could go wrong, including hiring incompetent EEs, does go wrong. But the story is very well told, and I think worth a listen by anyone who might ever be involved in such a project. The bottom line, as both Dave and Chris would confirm, is that hardware is really hard to do.
Don now does two podcasts at photogeekweekly.com, both of which are deliberately technical. Fair warning.
