24 Virtually all Altus Metrum inventory was destroyed in the fire
25 that devastated Black Forest, Colorado, in June of 2013. More
26 details are available on the [gag.com](http://gag.com) site.
28 Some stock may still be available from these distributors:
31 * [Apogee Components](http://www.apogeerockets.com)
32 * [Bay Area Rocketry](http://bayarearocketry.com)
33 * [Chris' Rocket Supplies](http://csrocketry.com)
35 * [Australian Rocketry](http://www.ausrocketry.com)
37 * [Rebel Space](http://rebelspace.eu)
39 * [Aerospace Education](http://www.rockets.co.nz)
41 Rest assured, we're working as hard as we can to return Altus Metrum, LLC, to operational
42 status with a mixture of new and former products!
46 These products are all available for purchase:
48 * [TeleMetrum](TeleMetrum/)
49 is our flagship product, a dual-deploy rocketry altimeter with
50 GPS and bidirectional RF telemetry link.
52 * [TeleMini](TeleMini/)
53 is a smaller dual-deploy rocketry altimeter with telemetry using only a
54 barometric pressure sensor
56 * [TeleDongle](TeleDongle/)
57 is a simple RF interface for use in ground stations interacting with rockets
58 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
59 interface for other microcontroller systems.
61 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
62 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
63 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for Android devices!
65 * [LipoCharger](LipoCharger/)
66 is a standalone battery charger for the Lithium Polymer batteries used in
67 Altus Metrum products.
69 * [MicroPeak](MicroPeak/)
70 is a rocket altimeter that is both precise and tiny, designed to be the
71 ideal altimeter for model rocket contests.
73 * [MicroPeak USB Interface](MicroPeakUSB/)
74 provides an interface between [MicroPeak](MicroPeak/) and USB to
75 download flight log data.
79 These are projects we're working on that may become products someday:
82 is the name of the firmware and related utilities that Keith maintains for
83 the set of hardware projects here.
85 * [MegaDongle](MegaDongle/)
86 is a higher-performance alternative to [TeleDongle](TeleDongle/).
88 * [TeleMega](TeleMega/)
89 is a high-end flight computer with 6 pyro channels, more and better sensors,
90 GPS, and a high performance bidirectional RF telemetry link.
93 was Bdale's original project here, a dual-deploy rocketry altimeter. One
94 prototype was built, but never flown. This project is now indefinitely on hold.
96 * [TeleNano](TeleNano/)
97 is a tiny rocketry altimeter with telemetry using only a barometric
100 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
101 that adds 8 additional pyro channels.
103 * [TeleScience](TeleScience/) is a companion board for
104 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
105 analog sensor input, and 5 general purpose I/O lines.
107 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
109 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
110 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

116 The motivation for the circuits and software you will find on this site is
117 our loosely-knit group's shared interest in hobby rocketry. This very brief
118 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
119 quickly conveys at least part of why we do this. John Coker
120 has published an excellent
121 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
122 on his web site. Keith has also put together some useful notes about the
123 process of [certification](http://keithp.com/rockets/certification/) to
124 fly high power rockets.
126 To find more information about the rockets Bdale and his son have built, see
127 [Garbee Rockets](http://www.gag.com/rockets).
129 As Bdale and Robert became more experienced in the hobby and started to build
130 and fly more sophisticated projects, we started to feel limited by the
131 existing electronics products available. OpenAlt was Bdale's first
132 attempt to address this situation with a completely open hardware and software
133 design... other project have since followed, and it's cool to have help from
134 Keith and other friends!

142 If you aren't already playing with model rockets, that's a good place to
143 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
144 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
145 learn a lot and see some great flights by showing up at a club launch.
147 As we make progress, you can read about it in our [News](News) feed. Feel
148 free to subscribe to our
149 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
150 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
151 questions that aren't answered here. You can also find us on
152 [Facebook](http://www.facebook.com/group.php?gid=341167482968)

156 Our main projects include radio links. If you don't already have one,
157 getting an [Amateur Radio](./Radio) license would be a good thing to do!
159 And if you just can't wait to show your support for our efforts, visit
160 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
161 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
162 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
