Our pals at Adafruit have released kits for their most awesome Tweet-a-Watt, a kit that turns a lonely Kill-a-Watt power meter into a Twittering energy-usage reporter. Now you can tweet your ravenous power hunger to the entire world!
The Tweet-a-Watt Starter Kit, with everything you need to create one outlet monitor (minus the Kill-a-Watt unit), costs $90. Additional Add-on outlet kits sell for $40. We should have Tweet-a-Watt kits in the Maker Shed soon and will let you know as soon as we do.
How to make your own Tweet-a-Watt will also be one of the major projects in MAKE, Volume 18, so stay tuned for that.
