Luis Cruz just graduated from high school but don’t let his young age fool you, he is already developing some very serious systems. His low cost eye tracking system uses Electrooculography to detect the movements of a person’s eyes. This then allows a person to control an electronic or computer system just by looking around. He has also received some CNN coverage, see the CNN video below. Read about the
This Hot Glue Climbing Robot from the Bio-Inspired Robotics Laboratory at ETH Zurich isn’t exactly practical but it is an interesting concept. The robot can climb almost any surface by attaching itself by using glue. The biggest disadvantage of this method is that hot glue takes a long time to dry where it can support the weight of the robot. Via: ieee Spectrum
A noisy fan inside a AC Ryan Media Player caused Gerrit van Donk to use the PWM Fan Controller Chip from the PWM Fan Controller Project. This will allow the fan to remain off when the unit is cool inside and only turn on when the system generates some heat. There is a hard drive inside so I would assume this will be the main source of heat but they
I was just catching up on some episodes of The Amp Hour and heard about this DIY Pick and Place Machine by Build Your Own CNC Router Machine. I love the fact that the entire thing has been constructed from everyday items. It isn’t the fastest thing but I love machines that you can program and walk away and get something else done while it completes the task. If you
Seekway makes some huge LED displays, this LED Display uses 76 thousand LEDs to generate 3D Images. Creating one of these would be a lot more than a weekend project and unless you have a big building entrance to put it in I doubt you would get much use out of it but it can sure lend some inspiration to some smaller builds.

Check out this IBM Thinkpad that took a Zap from Huge Tesla Coil and Lives. I personally didn’t think it would last for more than a few seconds. Thanks to The Geek Group for performing the test.
Lots of you know that there are different materials in LEDs to allow them to emit the color you desire. For example Gallium is used in many blue LEDs and other electronic devices. I had never seen the property that Gallium has to weaken metals though. In the videos below Nerd Rage demonstrates how a small amount of Gallium can disrupt the strength of some metals and allow it to
