-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! -

+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.
