-A quick update as of 24 November 2008. -The existing ARM7-based 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. -The schematic is under design review now, PCB layout will begin soon, and we hope -to be turning on boards and writing firmware over the Christmas / New Years holiday season. -Stay tuned! -
--Welcome LCA, SCALE, and OLS 2008 attendees! -Thanks for looking, but there's not much here yet... -
+ +Open hardware and software designs +for high powered model rocketry by +[Bdale Garbee](http://gag.com/~bdale) and +[Keith Packard](http://keithp.com/keithp).-Information on the OpenAlt model rocketry avionics system coming very soon! -

Additionally, starter kits are available from our distributors, +including [Apogee Components](http://www.apogeerockets.com), +[Australian Rocketry](http://www.ausrocketry.com), and +[Aerospace Education](http://www.rockets.co.nz) in New Zealand. + +# Download the latest [AltOS](AltOS/) software version # + +# Products # + +These products are all available for purchase: + +* [TeleMetrum](TeleMetrum/) +is our flagship product, a dual-deploy rocketry altimeter with +GPS and bidirectional RF telemetry link. + +* [TeleMini](TeleMini/) +is a smaller dual-deploy rocketry altimeter with telemetry using only a +barometric pressure sensor + +* [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. + +* [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. + +# 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. +* [MicroPeak USB Interface](MicroPeakUSB/) +provides an interface between [MicroPeak](MicroPeak/) and USB to +download flight log data. + +* [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.-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! -
+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!

+# 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
+[Facebook](http://www.facebook.com/group.php?gid=341167482968)
+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) 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!
