Check out this video footage of a great Pi powered high altitude ballooning (HAB) project via raspberrypi.org:
The project started when we all came together with the idea of launching our own weather balloon, to gather scientific data. We got our inspiration from our passion for Physics, and by other launches that has been completed by other people, such as Dave Akerman, the first to launch a Raspberry Pi on a high altitude balloon. We started by seeing how feasible the project would be, by planning out how we would complete it, and pricing it up. We then went to our school, and in turn the Ogden Trust, to look to secure funding.
Featured Adafruit Products
High-altitude balloon – Skill badge, iron-on patch – You sent something to SPACE! Almost Adafruit offers fun and exciting “badges” of achievement for electronics, science and engineering. We believe everyone should be able to be rewarded for learning a useful skill, a badge is just one of the many ways to show and share. (read more)
BMP085 Barometric Pressure/Temperature/Altitude Sensor- 5V ready – This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! (read more)
Adafruit Assembled Pi Cobbler Breakout + Cable for Raspberry Pi – Now that you’ve finally got your hands on a Raspberry Pi® , you’re probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. (read more)
