Soren from energyconsumption.org has joined the energy measuring resource quantifying savings suggesting future pontificating environmental investigating blogging team here at electrimetric. If you haven't already check out energyconsumption.org and check back here for posts from him.
Featuring an aluminum, curvilinear design, a series of diecast cooling fins dissipate heat from the internal circuitry. Meanwhile, LEDs put out 400 lumens for 50,000 hours while sipping on just 7W.
If you're interested, the bulb is available for $30. Otherwise, you should just try to convince your modder friend to incorporate it into his next case design. Maybe some gross ode to Thomas Edison. [Chinavision via 7gadgets]
What can you do with Tweet-a-watt? Many things, not the least of which include monitoring your domestic power usage without having to hack your main power grid (handy, especially if you’re a renter). The Tweet-a-watt automatically uploads the data to your Twitter account for sharing, competing or bragging. There’s nothing like a little public accountability to keep us all honest!
Designed by MIT graduate and open-source maven Lima of ladyada, Tweet-a-watt is an open-source hack with a green heart. You can make your own Tweet-a-watt by opening up an off-the-shelf Kill-a-Watt power monitor and making a couple simple modifications - wire an Xbee wirelss module, super capacitor and transmission indicators to the power sensor output, then syc it to an Xbee reciever connected to your PC via USB. Clear as mud? Never fear, Ladyada.net has all the details mapped out nicely — with diagrams !
