![Altus Metrum Logo](mediumlogo.png) Open source hardware and software avionics solutions for the hobby rocketry community.
Open source hardware and software avionics solutions for the hobby rocketry community from [Bdale Garbee](http://gag.com/~bdale) and [Keith Packard](http://keithp.com/keithp). All hardware designs on this site are licensed under the [TAPR](http://www.tapr.org/) [Open Hardware License](http://www.tapr.org/ohl.html), and all the software is under the [GNU](http://www.gnu.org/) [General Public License, version 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html) or compatible licenses. # Projects # * [TeleMetrum](TeleMetrum/) 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. * [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for [TeleMetrum](TeleMetrum/). * [TeleScience](TeleScience/) is a planned expansion board for [TeleMetrum](TeleMetrum/) providing 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. 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. And if you're a Facebook user, you can join the [Altus Metrum](http://www.facebook.com/group.php?gid=341167482968) Facebook group. Our main projects include radio links. If you don't already have one, getting an [Amateur Radio](./Radio) license would be a good thing to do! 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! --- ![United States flag](USflag.png) Altus Metrum products are designed and manufactured in the United States of America. --- 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).
