BALLOON - HIGH ALTITUDE
High altitude balloon attempt for later this year. Most of the parts are ready to go, just waiting on a few camera's for interval still images, Eric might have his video camera ready, Jason will provide the GPS and tracking, and I will get my WHISTLE dog tracker in the payload box.
Parts list and checklist is all ready, just some fine tuning.
Update 03/24/2016 - Nikon Coolpix camera came in, a $20 bid on EBAY with 2 GB flashcard. Tested the camera out today for interval stills - 30 sec intervals - and had around 450 images in around 3 hours time-span. This camera performs great and has 12 MEGAPIXELS and the images are like 4 - 5 MB each.. Really cool camera.
Other camera that I have is also a Nikon S9 but is 7 MEGAPIXELS, performs also great with over 250 images on that battery in around 2 + hours.. All will be great.
