  • The BMP085 is only rated to about 9000m (29,528 feet). That is about half of the height I would expect from a near space balloon. Has anyone confirmed that this pressure sensor reads properly beyond the 9000m pressure level?

  • Looks like I lost my balloon at about the same time you guys did…and not too far away from you either. It’s surprisingly harder than it looks to keep track of them. If I launch another balloon I would do everything the same, except I would add in an XTend zigbee radio. My best guess was that my balloon reached an altitude above cellphone range and then drifted to an area where there was no coverage when it landed. The long range zigbee radio would solve that issue. You can check out my partial success at nearspaceballoon.blogspot.com. I used a lot of Sparkfun parts in my build. Thanks for great parts and prices!

No public wish lists :(
