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 # * [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. * [TeleMetrum](TeleMetrum/) is our current project, a dual-deploy rocketry altimeter with improved sensor complement and bidirectional RF telemetry link. * [TelePyro](TelePyro/) is an 8-channel pyro expansion board for [TeleMetrum](TeleMetrum/). * [TeleTerra](TeleTerra) is a hand-held ground station for use with [TeleMetrum](TeleMetrum/). * [AltOS](AltOS/) is the name of the firmware and related utilities that Keith maintains for the set of hardware projects here. # Participants # * [Bdale Garbee](http://gag.com/~bdale) * [Keith Packard](http://keithp.com/keithp) * [Carl Worth](http://cworth.org) # 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. 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! --- This site is powered by [ikiwiki](http://ikiwiki.info), and hosted by [Garbee and Garbee](http://www.gag.com) using [Debian GNU/Linux](http://www.debian.org) and [Apache](http://www.apache.org).
