21 All Altus Metrum products are available from the
22 [Garbee and Garbee](http://auric.gag.com) web
23 store. [TeleMetrum](TeleMetrum/) starter kits are also now available from
24 [Apogee Components](http://www.apogeerockets.com/Altus_Metrum_GPS.asp).
28 The motivation for the circuits and software you will find on this site is
29 our loosely-knit group's shared interest in hobby rocketry. This very brief
30 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
31 quickly conveys at least part of why we do this. John Coker
32 has published an excellent
33 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
34 on his web site. Keith has also put together some useful notes about the
35 process of [certification](http://keithp.com/rockets/certification/) to
36 fly high power rockets.
38 To find more information about the rockets Bdale and his son have built, see
39 [Garbee Rockets](http://www.gag.com/rockets).
41 As Bdale and Robert became more experienced in the hobby and started to build
42 and fly more sophisticated projects, we started to feel limited by the
43 existing electronics products available. OpenAlt was Bdale's first
44 attempt to address this situation with a completely open hardware and software
45 design... other project have since followed, and it's cool to have help from
50 * [TeleMetrum](TeleMetrum/)
51 is our primary project, a dual-deploy rocketry altimeter with
52 GPS and bidirectional RF telemetry link.
54 * [TeleDongle](TeleDongle/)
55 is a simple RF interface for use in ground stations interacting with rockets
56 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
57 interface for other microcontroller systems.
60 is the name of the firmware and related utilities that Keith maintains for
61 the set of hardware projects here.
63 * [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for
64 [TeleMetrum](TeleMetrum/).
66 * [TeleTerra](TeleTerra) is a planned hand-held ground station for use with
67 [TeleMetrum](TeleMetrum/).
70 was Bdale's original project here, a dual-deploy rocketry altimeter. One
71 prototype was built, but never flown. This project is now indefinitely on hold.

79 If you aren't already playing with model rockets, that's a good place to
80 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
81 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
82 learn a lot and see some great flights by showing up at a club launch.
84 As we make progress, you can read about it in our [News](News) feed. Feel
85 free to subscribe to our
86 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
87 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
88 questions that aren't answered here. And if you're a Facebook user, you
89 can join the [Altus Metrum](http://www.facebook.com/group.php?gid=341167482968)
92 Our main projects include radio links. If you don't already have one,
93 getting an [Amateur Radio](./Radio) license would be a good thing to do!
95 And if you just can't wait to show your support for our efforts, visit
96 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
97 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
98 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
