s if Twitter didn’t already focus on the most excruciating details of daily life, the Tweet-a-Watt is here to broadcast your power consumption to the world. Plus, each device only reads one outlet, so you can really get down to the nitty-gritty. Modified from a Kill-a-Watt energy reader, the Tweet-a-Watt slowly charges up just enough power to communicate with a nearby computer via an XBee receiver, then uses a predefined Twitter account to automatically publish the stats. After purchasing a $20 Kill-a-Watt, the package of DIY components cost $90. You can also buy additional kits for monitoring multiple outlets and coordinate with a single tweet for $40 each. You’ll be the pride of all your random followers.
