Check out this Stage Combat Choreography Shirt project that uses a Lilypad Arduino to control it. When learning stage combat audio cues are normally, Instructables user grossmr1 decided to create a method of directly indicating the area of interest directly by using LEDs. A glove is used to interface to the microcontroller which has contacts sewed into the finger tips. “Stage combat is the art of theatrical violence. Rather than
Kevin Martin and Hyundo Reiner from Cornell University made this Automatic Grapefruit Segmenter for their ECE 4760 Designing with Microcontrollers Final Projects. Watch the video below to see it in operation, the system first rotates the half grapefruit looking for the thick material that divides the segments. This is done by reading the feedback from a flex sensor. Once the entire half grapefruit segment locations have been mapped the
 We have seen lots of Wall-E designs built by fans of the movie before. Most Wall-E designs have some DIY electronics like the custom Wall-E track build we saw earlier this year. This Wall-E Engagement Ring Box may look similar to some of the DIY projects we have seen in the past with one big exception, it was built for the sole purpose of presenting an engagement ring!
The video above demonstrates what Vijay Kumar and his team are building. We have seen some toy quadcopters that have some impressive capabilities but I can’t wait till a tiny and smart quadcopter as agile as these are available. If you don’t have the time to watch the entire video make sure you see the flight demonstrations at 10:05. Thanks for sending this in Matt. Â “In his lab at
 The prize this week is a pair of ESD Tweezers, just what you need to work with those tiny SMD parts. This contest will run for one week (March 4 – 9, 2012). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to contest
This Spray-on Antenna could revolutionize RF transmissions if their claims are true! Apparently nano capacitors are sprayed onto almost any surface to make it a powerful antenna. Via: PHYSORG Â “The company is promoting it as a multi-purpose antenna, simple and quick to assemble, mountable on almost any surface, for use in any environment. “Any” bears quite a range of possible end uses.”
Larry sent in his DIY Vacuum Motion Sensor Mouse Trap creation. “I built a mouse trap using an infrared motion sensor wall switch, an extension cord, a paper towel tube and a mini shop-vac. peanut butter is the bait. The mouse goes in the tube. The sensor senses it and turns on the shop-vac for 3 seconds. And voom, the mouse is inside the shop-vac. The sensor turns off
