It may also be useful as a generic RF +interface for other microcontroller systems. + +* [LipoCharger](LipoCharger/) +is a standalone battery charger for the Lithium Polymer batteries used in +Altus Metrum products. + +* [MicroPeak](MicroPeak/) +is a rocket altimeter that is both precise and tiny, designed to be the +ideal altimeter for model rocket contests. + +* [MicroPeak USB Interface](MicroPeakUSB/) +provides an interface between [MicroPeak](MicroPeak/) and USB to +download flight log data. + +# Projects # + +These are projects we're working on that may become products someday: + +* [AltOS](AltOS/) +is the name of the firmware and related utilities that Keith maintains for +the set of hardware projects here. + +* [MegaDongle](MegaDongle/) +is a higher-performance alternative to [TeleDongle](TeleDongle/). + +* [MegaMetrum](MegaMetrum/) +is a high-end flight computer with 6 pyro channels, more and better sensors, +GPS, and a high performance bidirectional RF telemetry link. + +* [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. + +* [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds +[Bluetooth](http://www.bluetooth.com) as an alternative to USB. + +* [TeleNano](TeleNano/) +is a tiny rocketry altimeter with telemetry using only a barometric +pressure sensor + +* [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. + +* [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield. + +* [TeleTerra](TeleTerra) is a hand-held ground station for use with +[TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/). + +# 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. 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! + +# [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. Feel +free to subscribe to our +[mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also +hang out on IRC channel #altusmetrum on irc.oftc.net if you have +questions that aren't answered here.
