existing electronics products available. AltusMetrum was Bdale's first
attempt to address this situation with a completely open hardware and software

is our current project, a dual-deploy rocketry altimeter with improved sensor
complement and bidirectional RF telemetry link.

+# 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.
+We also have an IRC channel #altusmetrum on irc.oftc.net if you have
+questions that aren't answered here.
