Simple Wifi Booster For Free


Learn how to make a simple (basically free) wifi antenna booster using tin foil. Yes, it sounds crazy, but it actually works and significantly increases your wifi signal in the dead zones of your house. The video above is pretty lengthy, but does a good job walking you through a few optimal designs.

Hip-Hop Basslines Could Power Implantable Medical Devices


Your favorite hip-hop artist could save a life someday — or at least control a person’s bladder — through the power of heavy bass beats, according to new research. Acoustic waves from rap music shudder through your body with ease, and can readily power a new implantable medical device.

Psychedelic Sphere of LEDs

The friend of a performer created this optical light display of 256 LEDs that can be programmed to create some fascinating displays.  The ball has 16 panels, which are not only the circuit boards, but the structural support of the ball as well. The central brain is provided by an Arduino powered by two AA batteries.  For more information, see the full project details (the site may be temporarily down).

An Aerial Drone That Could Recon the Skies Over Titan


Drones: they’re not just for controversial cross-border airstrikes anymore. Physicist Jason Barnes has designed a robotic aircraft that could cruise the methane skies of Saturn’s moon Titan almost indefinitely, beaming data and images back to Earth and terminating with extreme prejudice any terrorist threats it encounters there (we made that last part up).

Eye Controlled Computer




The eyeboard is an open source project that was built in order to help people with disabilities. His circuit detects the eye movements using the technology called "Electrooculography". Which consists in detecting the resting potential that exists between the retina and the cornea by using skin electrodes around the eyes.

£16 Computer Gets Close To Launch



BBC News : The eagerly anticipated Raspberry Pi home computer is about to go into production.

The $25 (£16) machine is being created in the hope that it will inspire a new generation of technology whizz kids.

The Pi uses an Arm chip similar to that found in mobile phones and is intended to run a version of the Linux open source operating system.

Test versions of finished devices are being checked and if all is well volume production will start in January.

Build a POV Light Tube


With this POV light painter, you can paint the town red or any other color that suits your fancy. The LightScythe is a 2-meter long POV tube made up of multi-color LED strips.  POV stands for Persistence of Vision which describes how our eyes see motion blur when an object is moving quickly.  In this case, it enables us to see a message written with light.


An image is loaded onto a laptop which converts it to serial data, then sends it to an Arduino which controls the lightbar. A camera is set for 10 to 15 seconds of exposure, during which time the user walks across the frame, painting the image to be caught by the camera.
