3 and friends document work on open hardware and software designs for
4 high powered model rocketry avionics solutions.
5 Please consider everything here work perpetually in process!

17 The motivation for the circuits and software you will find on this site is
18 our loosely-knit group's shared interest in hobby rocketry.
19 Rather than try to introduce the hobby to you here, we note that John Coker
20 has published an excellent
21 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
24 To find more information about the rockets Bdale and his son have built, see
25 [Garbee Rockets](http://www.gag.com/rockets).
27 As Bdale and Robert became more experienced in the hobby and started to build
28 and fly more sophisticated projects, we started to feel limited by the
29 existing electronics products available. AltusMetrum was Bdale's first
30 attempt to address this situation with a completely open hardware and software
31 design... other project have since followed!
35 * [AltusMetrum](AltusMetrum/)
36 was our original project, a dual-deploy rocketry altimeter. One prototype was
37 built, but never flown. This project is now indefinitely on hold.
39 * [TeleMetrum](TeleMetrum/)
40 is our current project, a dual-deploy rocketry altimeter with improved sensor
41 complement and bidirectional RF telemetry link.
