Energy Meter

My buddy Frank (the guy talking way too fast above) and I designed an open source energy meter. It is still in early beta, but Frank’s about to be commissioned in the Navy, and I have a three month Merchant Marine cruise coming up, so neither of us will have time to work on it for a while. Anyways, it’s pretty awesome if I do say so myself. It’s similar to the Kill A Watt, but it’s wireless, uses mesh networking, and is scalable from a metering a single outlet to service as building’s primary energy meter.




Also, I wrote an OS X Cocoa application for an interface to sensors. Currently, it only recognizes one sensor, but with a little modification I’ll make it handle any number of sensors. We even configured the sensors to occasionally send current and voltage waveforms. That’s mostly eye-candy, but could be useful to a utility to identify problems or particularly noisy loads.




If you’re interested in getting involved, let us know. You can check out the live code at our Google Code page.
