RaptorTech’s goal was to drop a glider from the edge of space, and with a Raspberry Pi and a high-altitude weather balloon, their vision became a reality.
Here at Pi Towers, we thoroughly enjoy the link between high-altitude balloon (HAB) enthusiasts and the Raspberry Pi community, from Dave Akerman‘s first attempt at sending a Raspberry Pi to near-space, to our own Skycademy programme training educators in high-altitude ballooning. HABs and the Pi go together like the macaroni and cheese, peanut butter and jelly, chips and gravy…you get the idea.
The RaptorTech team equipped their glider with a Pixhawk flight controller and the small $5 Raspberry Pi Zero to control the time point when the glider disconnects from the HAB, and to allow the glider to autonomously navigate back to a specific landing site.
They made the glider out of foam core and coroplast, with a covering of tape to waterproof the body. Inside it were two cameras, two servos, the Raspberry Pi Zero, and the Pixhawk flight controller with added GPS tracker (in case the glider got lost on the way home). The electronics were protected by handwarmers from freezing at high altitude.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
