# Using Altus Metrum Products
## Where to Buy ##
All Altus Metrum products are available from the
-[Garbee and Garbee](http://auric.gag.com) web
+[Garbee and Garbee](https://shop.gag.com) web
store. [TeleMetrum](TeleMetrum/) starter kits are also available from
[Apogee Components](http://www.apogeerockets.com/Altus_Metrum_GPS.asp)
and [Australian Rocketry](http://www.ausrocketry.com/shop/index.php?main_page=product_info&cPath=111&products_id=4302).
In the future, we intend to offer "companion boards" for the rocket that will
plug in to TeleMetrum to collect additional data, provide more pyro channels,
-and so forth. A reference design for a companion board will be documented
-soon, and will be compatible with open source Arduino programming tools.
-
-We are also working on the design of a hand-held ground terminal that will
-allow monitoring the rocket's status, collecting data during flight, and
-logging data after flight without the need for a notebook computer on the
-flight line. Particularly since it is so difficult to read most notebook
-screens in direct sunlight, we think this will be a great thing to have.
-
-We're also contemplating other altimeter designs with either more or less
-features than TeleMetrum aimed at different needs within and beyond the rocket
-community.
+and so forth. We've built and flown some prototypes including
+[TeleScience](/TeleScience), but no companion board designs have made it to
+production yet.
+
+We intended to publish a reference design
+for a companion board, but one of our customers beat us to it! You can find
+his work on how to use an Arduino as a companion board on
+[GitHub](https://github.com/robderstadt/AltOSCompanion).
Because all of our work is open, both the hardware designs and the software,
if you have some great idea for an addition to the current Altus Metrum family,
