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. +
+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. OpenAlt 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 +Keith and other 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 +GPS 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. + +* [TeleMini](TeleMini/) +is a smaller dual-deploy rocketry altimeter with telemetry using only a +barometric pressure sensor + +* [TeleNano](TeleNano/) +is a tiny rocketry altimeter with telemetry using only a barometric +pressure sensor + +* [AltOS](AltOS/) +is the name of the firmware and related utilities that Keith maintains for +the set of hardware projects here. + +* [LipoCharger](LipoCharger/) +is a standalone battery charger for the Lithium Polymer batteries used in +Altus Metrum products. + +* [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/) +that adds 8 additional pyro channels. + +* [TeleScience](TeleScience/) is a companion board for +[TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic +analog sensor input, and 5 general purpose I/O lines. + +* [TeleTerra](TeleTerra) is a planned hand-held ground station for use with +[TeleMetrum](TeleMetrum/). + +* [OpenAlt](OpenAlt/) +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. + +# [Using Altus Metrum Products](Uses) # + +# [Presentations](talks) # + +# 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.
