Twitter users will be pleased to know that they have yet another method to share what’s going on in their lives with the Tweet-a-Watt. This device will help you share your power consumption with all and sundry, but be warned that each device is only able to read an individual outlet. You will need to modify a $20 Kill-a-Watt energy reader so that it will charge up just enough juice to “talk” to a computer using an XBee receiver, where a pre-defined Twitter account will automatically publish the results. The DIY components will set you back by another $90, and if you’re feeling flush, there is the option to pick up extra kits for monitoring multiple outlets to co-ordinate with a single tweet for $40 a pop.
