Next weekend, if everything goes well, a 15x30cm carbon deck will fly onboard HAPS-1 -http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1
One end of the deck will be the flight radio, the other is my responsibility, a single camera (Powershot A560 ), stand alone GPS logger (to 18km), and a small wide angle mirror so the camera can see the payload, the chute and the envelope above. Still working on a hacked firmware for the A560 - but the intention is every minute will include 15s of video, and then 5-10 stills in fairly quick succession - with the hope that the rotation of the balloon will give us some mosaics out of each section. More details, some photos etc, later in the week. |

The 'flight' SD card ( and a flight spare ) have arrived - the Sandisk Extremem III 4gb SDHC card.
From Sandisk.com QUOTE # Ideal for demanding photo shoots under severe weather conditions—heat, cold, wind, rain, snow, etc. # Built to perform in the most extreme environments and temperatures—from -13º F to 185º F -25º C to 85º C # Min 20MB/second** sequential read and write # Durable, reliable and thoroughly tested—temperature tested (heat and cold); shock and vibration tested OK - not the -50 we may see on flight - and sadly we wont get values for the flight min/max temp (next time maybe) - but it's the sensible option just to get the most robust card I can reasonably find. After the joy of 200hz Phoenix EDL data - I desperately want to log Acceleration for the next flight. The motherboard doing the work on the avionics side has an accelerometer, but it's very much KISS this flight, and no data volume to save such a a large data set either - but I'm going to push to try and achieve that next time around. Foam enclosure is finished, deck has foam underneath as a stand-off on which the 1/4 wavelength antenna will go. |
