Justin (Potatono) has made a cool looking Binary LED clock called Time to Hack. You can find information about the clock at Thingiverse and NYCResistor. "Use three pieces of acrylic, each with similar holes cut in them. The top piece only has four holes for the mounting screws that hold the whole thing together and the "Time To Hack" etch. Under that is the clear piece with holes for
Looks like motor technology and battery technology have finally evolved to the point where electric planes will be viable. With a few hour charge this electric airplane will give you 1 hour of flight time. The 75 volt battery pack delivers 200A of current to lift off and a full charge takes about $0.75 of electricity! "We have converted my single place, all metal Moni motor glider into a small,
Is the SixthSense the future of wearable computer interfaces? Everyone today has a pocket full of technology but the interaction with these devices can be clunky. This interface would allow you to interact with your camera, phone, computer amongst other items with ease. "SixthSense is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with
Wow, this tiny Xbee 900 rf module is supposed to have a range of 15 miles. We all know that these specs are always best case scenarios that are not attainable in the real world but it probably means that we could get 9 or 10 miles out of it. I can just imagine the projects that could be possible with this type of range! "The XBee-PRO XSC OEM
Keith has a good example of making a electronic repair with parts at hand. This 300 dollar sign was going to be thrown in the garbage because of a few burnt out and dim LEDs. After the sign was opened Keith would have replaced the 10mm White LEDs if he had some but he didn’t, his next idea was to drill out the rear of the 10mm LEDs and
If you need to add color sensing to your next LEGO project have a look at this RCX Input Mux & Color Sensor. Full schematics and circuit description is provided. "Color sensing depends on measuring the intensity of light at different wavelengths. A spectrometer does this by splitting the light with a prism or diffraction grating into its component wavelengths. However, spectrometers are complex and too difficult to build.
We have seen lots of intelligent methods of monitoring and curbing energy usage recently. The hacked Kill-a-Watt comes to mind. This SmartSwitch device is a prototype device that would allow you to feel how much energy you are using. If the light switch is hard to turn on that is because you are already using lots of energy and the internal brake is on. This would hopefully make you
