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. +
+To find more information about the rockets Bdale and his son have built, see +[Garbee Rockets](http://www.gag.com/rockets). +
+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. + +* [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 Bdale's original project here, a dual-deploy rocketry altimeter. One +prototype was built, but never flown. This project is now indefinitely on hold. + +# Participants # + +* [Bdale Garbee](http://gag.com/~bdale) +* [Keith Packard](http://keithp.com/keithp) + +# [Presentations](talks) # -# [TeleMetrum](TeleMetrum/) +# Getting Involved # -This is our latest project, a rocketry altimeter with RF link. +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. -# [AltusMetrum](AltusMetrum/) +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. -This was our original project, a rocketry altimeter. +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! -
