Raspberry Pi flew to 40 km of altitude and taught us the Earth from the stratosphere
Already there are many tests and exercises of shipment of mobile phones sent to space to get some fantastic from the stratosphere or from space pictures have been releases with helium balloons as launch directly into space by NASA or even Lego toys but this is the first made with a Raspberry Pi in a very special way given that these images were submitted and issued by radio in real time during the ascent of the device.
Dave Akerman has been the entrepreneur who wanted to carry out this exploit in order to send a Raspberry Pi a little less than 40 kilometers of altitude and get some fantastic pictures of our planet at that point with a built-in camera to take advantage of its premiere and see to examine the quality images that is able to take.
Una vez las condiciones climatológicas fueron favorables y con la correspondiente autorización por parte de la CAA (Autoridad de Aviación Civil del Reino Unido) fue otorgada y actualizado el firmware de la cámara del Raspberry Pi así como modificación de su código para la realización de tres tipos de imágenes que se tomarían cada minuto aproximadamente (una de poco tamaño y otra de tamaño medio para enviarla por radio y una de gran resolución para ser almacenada en la tarjeta SD del Raspberry Pi) y ultimar los detalles como la batería del dispositivo llegó el momento del lanzamiento del globo de hidrógeno con el Raspberry Pi to achieve the goal of the 40 kilometers of altitude.
During the approximately three hours of ascent both Dave Akerman as other listeners located in Northern Ireland, France or the Netherlands which had the radio frequencies used by the Raspberry Pi they enjoyed in real time the images that were being shipped from the same.
Time-controlled and calculated approximate landing area, Dave went out of way to the meeting of its Raspberry Pi While at the same time still showing images that was taking up to fall on account of miscalculation is that to have delayed the launch two hours he did not consider small winds that altered the trajectory of the globe. We must bear in mind one thing and is that the Raspberry Pi does not have GPS so its location is much more traditional with the use of force of the built-in radio broadcast both the predictable calculation in Raspberry Pi.
The calculation provided by the route that would take the balloon was useless due to the change of course caused by the wind and the strength of the radio frequency may be impossible to take account of the fall of a device to 40 km height in free fall once burst the balloon of hydrogen being extremely optimistic think that the device, the radio station or the batteries would hold this fall by rather welded that were.
Thanks to having put your phone in the Raspberry Pi He managed to recover his material and is that just when was it to give lost, He received a call from someone asking if I had lost a balloon with a raspberry hung on it so at the end the experiment and experience ended happily with a fantastic images that are visible through this gallery of images that were stored on the card built-in SD in the Raspberry Pi.
