Our favorite $25 computer has proven that it can work for you any way you want. It has been used in simple projects like voice activated garage doors and high-tech ones like wardriving. Now it is headed for the skies thanks to UK’s Dave Ackerman. He made use of the mini computer’s newly launched $25 camera attachment to capture gorgeous images of earth from a height of about 40 KMs from the ground.
Dave used the Model A of the Raspberry Pi computer along with its 5MP camera attachment (also capable of capturing 1080p videos) and attached it to a hydrogen balloon and a parachute. He set the camera to capture images of three quality types. The low and medium quality images that would be sent back to two wireless receivers and high quality images would be stored on the on-board SD card. In order to track location and flight path of the computer he installed a tracker powered by AA batteries that would last for the entire fight time. To make sure that only the “good” images are stored in the SD card the on-board software deleted the images that had bad exposure settings. At the end of the three hour flight the balloon burst the parachute was deployed for a safe landing of the 1.1kg payload that had been embedded in a piece of memory foam shaped like the Raspberry Pi logo. The above project also be seen as a low cost alternative to the PhoneSat projects.
