Yesterday, I got a digital camera for the project. This is actually the main dr
project - to get my own photos from space (well, 35km is not space yet - The Kar
altitude of 100km is generally used to define the boundary of Earth's atmosphere
so its only a third of the distance - still 3x higher than from a commercial air
camera should one get that can withstand the harsh conditions of temperatures be
Celsius and an unknown amount of shock, and maybe crash landing back to earth.

I'm starting a new personal project in High Altitute Ballooning and would like t
case anyone has some experience/interest to share in this fasinating hobby. My g
small helium-filled weather balloon carrying a small payload of a few instrument
of a camera, a few sensors and tracking electronics to successfully retreive the
balloon will ascent at a rate of 3-5 m/s untill it reaches its bursting point at
29-34 km, when the payload will fall back to earth. A parachute is attached und
to provide a fairly save descent rate of 5-8 m/s for the payload. The payload ma
kilometers away from the launch point (depending on the wind at various levels),
it, hopefully contains some interesting data and video/photos from the earth at
the distance to space.

Today I tried out the gopherspace on SDF. It works a lot like ftp sharing, just
can use this space to keep a blog (called a phlog or glog) or just share documen

file in the tutorials section on the sdf.org website.
