That is exactly what the Ghetto BPM Detection does. 🙂 “This one is inspired by my experiences with the band and the DJ-Set and…well…you know why =-). Anyway, for already quite a long time I am looking for a way

What Will Scientists Do With the World’s Smallest Microwave? - Inventor Spot

Scientists have constructed a “micro microwave,” a long, narrow device measuring 4 mm long by 7 micrometers wide (the width of a red blood cell). Considered to be the smallest microwave ever, the technology will likely be used for medical “lab-on-a-chip” devices. Micro microwave:: The gold traces on the glass circle are microwave transmission lines. The 1.25 cm wide polymer block over the transmission line in the center houses a

Tracking fingers with the Wii Remote

The Wii Remote has an infrared camera in the front that is normally watching for the infrared LEDs that are mounted in the sensor bar. This camera is actually quite sensitive and can be used for some cool things! Jcl5m has come up with a method that uses reflected IR light from small reflectors to provide the Minority Report style interaction. Via: Hack a Wii

VJ System - Vocal Joystick

The University of Washington is working on an amazing voice recognition system called VJ which stands for Vocal Joystick. No it doesn’t do text to speech like everyone else is doing, it allows simple vocal sounds control your computer mouse. After watching the videos it looks much easier than the other technologies I have seen in the past. More videos after the jump. “The goal of this project is to

Electronic Tic-Tac-Toe
