Urban Sonar is a personal space monitoring system that senses an individual’s experience as they move through the urban environment and records that information for review at a later time. Turning the gaze both outward and inward, negative space surrounding the individual and their heart rate are used to visualize a lived experience through quantitative data.[link] | [via]

Richard Parker shows you “How to build a web connected gas meter with Arduino” and displaying gas usage in real-time on Pachube which is a service that enables you to connect, tag and share real time sensor data from objects, devices, buildings and environments around the world.
The main sensor on this unit is a photo-reflector, which is a fancy name for an infrared LED and an infrared sensor in one assembly. When the infrared sensor detects a reflection from the infrared LED, the strength of that reflection is fed back into the Arduino.

arduino sonar buzzer php twitter from Joshua McGinnis on Vimeo.
Twitter again, this is more fun for Twitter users. The farther you are away from the computer, the larger the text and the greener the screen. Otherwise, the text becoming smaller and redder the screen, if you getting closer to the computer, It is use Maxbotix LV-EZ2 ultrasonic range-finder , arduino diecimilia and buzzer.
arduino & sonar returns your distance away from the computer and it is displayed on the screen. the farther away you are from the computer the larger the text and the greener the screen. the closer you are, the smaller the text and the redder the screen. get within 5 inches and a buzzer alarms. distance is twittered.
