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 * [EasyMini](EasyMini/)
86 is a small dual-deploy rocketry altimeter using the MS5607 barometry
89 * [MegaDongle](MegaDongle/)
90 is a higher-performance alternative to [TeleDongle](TeleDongle/).
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 * [TeleMega](TeleMega/)
97 is a high-end flight computer with 6 pyro channels, more and better sensors,
98 GPS, and a high performance bidirectional RF telemetry link.
100 * [TeleNano](TeleNano/)
101 is a tiny rocketry altimeter with telemetry using only a barometric
104 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
105 that adds 8 additional pyro channels.
107 * [TeleScience](TeleScience/) is a companion board for
108 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
109 analog sensor input, and 5 general purpose I/O lines.
111 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
113 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
114 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

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

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

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

171 Altus Metrum products are designed and manufactured in the
172 United States of America.
