The little power tweeter is making the engineering rounds…
ReMake America! These challenging times have presented us with a rare chance to try out new ways of doing things. The opportunities for makers are terrific — we can start at home to remake manufacturing, education, food production, transportation, and recreation. In this volume you’ll learn how to make an automatic garden, heat your water with the sun, monitor and share your home energy usage, and more in MAKE Vol 18.
Tweet-a-Watt Successfully Combines Personal Fabrication, Social Messaging, and Green Electronics by Matthew Traum @ Design News.
…the Tweet-a-Watt, monitors and reports energy consumed by appliances and electronics plugged into it. As reported in “Show of Power” in Mechanical Engineering Magazine, electricity from a capacitor runs an embedded XBee wireless module within the Tweet-a-Watt just long enough to send daily data through a computer to the Internet. There a social messaging service like Twitter displays the results.
In his 2005 book “FAB: The Coming Revolution on Your Desktop – From Personal Computers to Personal Fabrication” Neil Gershenfeld describes the future of engineering design as moving away from mass production to personal fabrication. According to Gershenfeld, driven by the desire for personalized products, people will begin modifying technology by adapting commercial products for unique personal applications. A look at the Adafruit Industries Web site suggests the first wave of Gershenfeld’s personal fabrication future is already here.
SHOW OF POWER by Jeffrey Winters @ Mechanical Engineering magazine, ASME Int’l (the American Society of Mechanical Engineers).
For most people, the only time they are aware of their power consumption is when the utility bill arrives. Then, it’s tidily totaled for the month. But a gadget that would enable users to publish their daily electricity usage won a green industrial design competition in February…
