Finally, you can add that very special member to your online social network—your houseplant.
Why would a plant want to join your network? To let you know when it’s thirsty, of course. Also to regularly report on its moisture level and to periodically thank you for watering it.
The network we’re talking about is Twitter, a group-oriented “microblogging” tool. This Web service keeps networks of friends, colleagues, businesses, and total strangers in contact through barrages of short messages known as “tweets.” And everybody from Barack Obama to the New York Times to my niece seems to be Twittering these days.
So why not Phil, the wilting philodendron that lives in your bedroom?
All you need is a clever do-it-yourself kit from a company called Botanicalls (cost: $89.95). With it you can build an electronic moisture-sensing system that enables one lucky houseplant to join your Twitter group. (Have a look at one houseplant’s tweets.)
This is a fairly geeky project, involving circuit boards, capacitors, ethernet cables, and a soldering iron, among other special equipment. But the kit’s instructions look clear, deliberate, and user-friendly. For a preview, see the company’s getting started and assembly page.
FYI, Botanicalls started out several years ago with a kit that enabled your plant to contact you by telephone, which they now call the Classic kit. If you need a break while you’re building the Twitter kit, I recommend you periodically watch the hilarious video that explained the Classic. It’s at the end of this post.
