DIY Air Quality Balloons 44

An anonymous reader writes "A few students at Carnegie Mellon University outfitted weather balloons with air quality sensors, resulting in huge glowing balloons that respond to surrounding air quality. Their Instructables page shows that pretty much anyone can make these using a PIC, a tri-colored LED, and some off-the-shelf air quality sensors (about $10 each): 'This Instructable will show you how to make giant, super cool, glowing balloons that react to surrounding air quality. Inside each balloon is a tri-colored LED. This LED reacts to data from an air quality sensor, turning green, yellow or red based on low, average, and high values.'"
