-# 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. Rather than
-try to introduce the hobby to you here, we note that 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 primary project, a dual-deploy rocketry altimeter with improved sensor
-complement and bidirectional RF telemetry link.

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.

# Getting Involved #
[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.
-We also hang out on IRC channel #altusmetrum on irc.oftc.net if you have
-questions that aren't answered here.
