+# Hobby Rocketry #
+
+The motivation for the circuits and software you will find on this site is
+our loosely-knit group's shared interest in hobby rocketry. This very brief
+[Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
+quickly conveys at least part of why we do this. John Coker
+has published an excellent
+[overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
+on his web site. Keith has also put together some useful notes about the
+process of [certification](http://keithp.com/rockets/certification/) to
+fly high power rockets.
+<p>
+To find more information about the rockets Bdale and his son have built, see
+[Garbee Rockets](http://www.gag.com/rockets).
+<p>
+As Bdale and Robert became more experienced in the hobby and started to build
+and fly more sophisticated projects, we started to feel limited by the
+existing electronics products available. AltusMetrum was Bdale's first
+attempt to address this situation with a completely open hardware and software
+design... other project have since followed, and it's cool to have help from
+various friends!
+
# Projects #
* [TeleMetrum](TeleMetrum/)
- is our latest project, a rocketry altimeter with RF telemetry link.
+is our primary project, a dual-deploy rocketry altimeter with improved sensor
+complement and bidirectional RF telemetry link.
+
+* [TeleDongle](TeleDongle/)
+is a simple RF interface for use in ground stations interacting with rockets
+using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
+interface for other microcontroller systems.
+
+* [AltOS](AltOS/)
+is the name of the firmware and related utilities that Keith maintains for
+the set of hardware projects here.
+
+* [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for
+[TeleMetrum](TeleMetrum/).
+
+* [TeleTerra](TeleTerra) is a planned hand-held ground station for use with
+[TeleMetrum](TeleMetrum/).
* [AltusMetrum](AltusMetrum/)
- was our original project, a rocketry altimeter.
+was Bdale's original project here, a dual-deploy rocketry altimeter. One
+prototype was built, but never flown. This project is now indefinitely on hold.
+
+# Where to Buy #
+
+Altus Metrum products are available from the [Garbee and Garbee](http://auric.gag.com) web store.

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