+Open hardware and software designs
+for high powered model rocketry by
+[Bdale Garbee](http://gag.com/bdale) and
+[Keith Packard](http://keithp.com/keithp).
<p>
-A quick update as of 16 December 2008.
-The ARM7-based 'AltusMetrum' design has been shelved indefinitely.
-Working with Keith Packard, I recently embarked on a complete redesign based on the TI cc1111.
-We got there by deciding we need a low-power RF beacon for post-landing direction finding, learning
-of the existence of this part, then realizing that we could radically simplify things by using it
-as the basis for a completely new avionics design.
-The cc1111 integrates a full 70cm transceiver, 8051 processing core, and peripherals on one chip.
-We add to that a barometric sensor, temperature sensor, accelerometer, eeprom memory, and full LiPo
-battery support powered by a USB interface also used for configuration and post-flight data extraction.
-It looks like we can get all the features we want on a single board for less than the price of most
-commercial altimeter boards, with the only downside being dramatically reduced processing power.
-We have a complete schematic and a first pass PCB layout that is currently
-under review and improvement prior to sending out for raw boards.
-We hope to be turning on boards and writing firmware over the
-Christmas / New Years holiday season.
-Stay tuned!

+
+* [EasyMega](EasyMega/)
+is a high-end flight computer with 6 pyro channels, tilt limits, etc. The

+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. Note that we don't actually
+sell TeleDongle by itself, it is included in our
+[Starter Pack](http://shop.gag.com/ground-stations/starter-pack.html) offering.
+
+* [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
+[Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
+useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for
+Android devices, or a compatible iOS application available for sale from

+# 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. And thanks to Maddie for pointing out the paghes that
+[Lisa Richards](http://www.mapcon.com/model-rocket-maintenance-technology) maintains.

+To find more information about the rockets Bdale and his son have built, see
+[Garbee Rockets](http://www.gag.com/rockets).

-Here are photos of the version 0.1 PCB, which has enough issues to not be
-worth duplicating. Version 0.2 is coming soon, and will be fully documented
-on this site!

+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!

+# 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. You can also find us on

+and on
+[Google+](https://plus.google.com/109995815990298399569).
+
+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) and buy a
