DIY Air Quality Balloons
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.'"
posting links to other websites content. and internet news sites claim main stream media is crap, atleast they are capable of doing something of their own.
If you mod me down, I will become more powerful than you can imagine....
How about we suspend a metric buttload of automatic air fresheners to balloons, and set them off to counteract smoke from all the weed these guys are on.
It depends, on whether some idiot decides to paint on the sides of the balloons characters no one over 30 has ever seen with their middle fingers extended.
So, who has their middle finger(s) extended? The idiot painting the balloon, the characters painted on the balloon, or nobody over 30?
... and then they built the supercollider.
then the both of the air and ground of Iraq, you made these red too. such waste. look look, “”First they ignore you, then they laugh at you, then they fight you, then you win.“” So weak.
