Got one of these for my daugher. It is cool. But it is slow. She doesn´t see the point as yet and prefers her Ipad.
So I am not sure if I should file this under kids or make a new section called moms.
I got an accelerated interest in android development and wonderful site Hack a Day has a painless introduction by Greg R. Jacobs. Here are the direct links to the series including the introduction and SDK setup.
PowerTrekk is a portable fuel cell charger for use by outdoor enthusiasts who spend time away from the electricity grid. PowerTrekk provides instant power anywhere to electronic equipment such as mobile phones, digital cameras and GPS devices. PowerTrekk is a 2-in-1 solution that is both a portable battery pack and fuel cell. The portable battery pack can be operated on its own as a ready source of power or storage buffer for the fuel cell. The fuel cell enables instant charging from a deflated battery state without ever needing a wall charge."
I want one of these. Period.
Neuroscientist Paul Bach-y-Rita's work on sensory substitution has spawned BrainPort, a sensory remapping unit that uses the tongue as sensory input interface. BrainPort uses the tongue to map the image picked up by a camera into discrete electrical points with up to 600 image points. BrainPort has also been used to correct balance in patients with vestibular dysfunction. See the facinating video on Wired Science!
"Behold the latest ocular assault weapon from the Graffiti Research Lab, openFrameworks, The Fat Lab and The Ebeling Group: The EyeWriter. It is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic lateral sclerosis to draw using only their eyes....This instruction set details how to make your own solderless eyetracker for only $50 dollars using a hacked PS3 Eye and a cheap pair of sunglasses."
"The Sainsbury's in Gloucester, which opened in June 2009, has several kinetic energy plates installed in their parking lot. Each time a car drives over the plates, the motion of the plate creates energy. The energy is then stored and sent to the store to provide power to the checkout stations. Sainsburys says that the plates can supply 30 kWh of energy per hour."
Used instead of speed-bumps, energy that would just have been lost is harvested.
