3 and friends document work on open hardware and software designs for
4 high powered model rocketry avionics solutions.

19 The motivation for the circuits and software you will find on this site is
20 our loosely-knit group's shared interest in hobby rocketry. Rather than
21 try to introduce the hobby to you here, we note that John Coker
22 has published an excellent
23 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
26 To find more information about the rockets Bdale and his son have built, see
27 [Garbee Rockets](http://www.gag.com/rockets).
29 As Bdale and Robert became more experienced in the hobby and started to build
30 and fly more sophisticated projects, we started to feel limited by the
31 existing electronics products available. AltusMetrum was Bdale's first
32 attempt to address this situation with a completely open hardware and software
33 design... other project have since followed, and it's cool to have help from
38 * [AltusMetrum](AltusMetrum/)
39 was Bdale's original project here, a dual-deploy rocketry altimeter. One
40 prototype was built, but never flown. This project is now indefinitely on hold.
42 * [TeleMetrum](TeleMetrum/)
43 is our current project, a dual-deploy rocketry altimeter with improved sensor
44 complement and bidirectional RF telemetry link.
46 * [TelePyro](TelePyro/) is an 8-channel pyro expansion board for
47 [TeleMetrum](TeleMetrum/).
49 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
50 [TeleMetrum](TeleMetrum/).

60 If you aren't already playing with model rockets, that's a good place to
61 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
62 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
63 learn a lot and see some great flights by showing up at a club launch.
65 As we make progress, you can read about it in our [News](News) feed.
66 We also have an IRC channel #altusmetrum on irc.oftc.net if you have
67 questions that aren't answered here.
