If I could make one weatherproof, it would be neat to use one outside in my back yard to take some weather information from the internet over wifi and then control some relays that turn some water spigots and save a ton of water for my garden. In my head whenever I think about a 60 year old version of me in the year 2040, I've sort of burned out on writing code but still bust some out whenever I can use it to save water. And the kids will think I am lame for writing code that saves a few gallons, but we'll be right on the brink of that starting to matter a lot. Also it would be cool to use the same machinery to drive those little windows and fans to make a greenhouse stay perfectly the same temperature during the day. This is probably total overkill for one of these devices. But I could code the perl up in an hour or less and it would just work, and having something exist and just work is so much more satisfying than "this thing I keep saying I will do some year".
