Here is a link to pictures of an attempt by a group of Calpoly engineers to have a UAV glider bring back pictures from 100,000 feet. After some sleepless nights and an overwhelming amount of work on hardware and software we launched a glider in California Valley. The balloon reach about 31,000 before something caused it to cut away, possibly a strong downdraft caused the code to cut the glider from the balloon thinking the balloon prematurely popped. We latter found the fuselage and one wing of the aircraft near Bakersfield, thanks to a friend with a Christian Husky and GPS tracking on the APRS network.

How-To Tuesday: Arduino 101 & the PING))) ultrasonic sensor
The PING))) ultrasonic sensor is a really easy way to measure distance with a micro-controller. All you have to do is hook up 3 wires and upload some code. These sensors are great for robots, alarm systems, or any...
