Kevin286 is making a satellite transmitter circuit that can be forwarded to a website (!), he says:

I work at a small company that deals in GPS tracking via simplex satellite modems and as such have rescued quite a bit of junk before it’s scrapped….I’ve got (an) Axonn STX2 satellite transmitter…I’ve been working with the Arduino stuff for a little while now and have a basic understanding but I’ve never used the Arduino to ‘talk’ to anything before.

Sounds interesting…anybody have experience with these things? Help him out in the forums!
