Ultimately, a power meter can be an extremely helpful training tool—that is, if you’re actually going to use the data to make changes and track progress. But there are a few things you should ...
The Tweet-a-watt [13] is a hacked version of the standard Kill-A-Watt Plug in Power Meter. By piggybacking on the device's on-board LM2902N op-amp chip, the creator was able to get readings for voltage and current and transmit to a computer, which then sent this to Twitter via handle @tweetawatt.
