Re: "what is it?"
I haven't seen the episode, but I have seen advertised in hunting catalogs a "game camera" with a motion detector that will take pictures of wildlife when you're not around. Some of these may have a time interval feature.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
