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).

# 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.

# 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!

Altus Metrum products are designed and manufactured in the
United States of America.
