24 All Altus Metrum products are available direct from Bdale's
25 [Garbee and Garbee](http://auric.gag.com) web
26 store, and many are also available from these distributors:
29 * [Apogee Components](http://www.apogeerockets.com)
30 * [Bay Area Rocketry](http://bayarearocketry.com)
31 * [Chris' Rocket Supplies](http://csrocketry.com)
33 * [Australian Rocketry](http://www.ausrocketry.com)
35 * [Rebel Space](http://rebelspace.eu)
37 * [Aerospace Education](http://www.rockets.co.nz)
41 These products are all available for purchase:
43 * [TeleMetrum](TeleMetrum/)
44 is our flagship product, a dual-deploy rocketry altimeter with
45 GPS and bidirectional RF telemetry link.
47 * [TeleMini](TeleMini/)
48 is a smaller dual-deploy rocketry altimeter with telemetry using only a
49 barometric pressure sensor
51 * [TeleDongle](TeleDongle/)
52 is a simple RF interface for use in ground stations interacting with rockets
53 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
54 interface for other microcontroller systems.
56 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
57 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
58 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for Android devices!
60 * [LipoCharger](LipoCharger/)
61 is a standalone battery charger for the Lithium Polymer batteries used in
62 Altus Metrum products.
64 * [MicroPeak](MicroPeak/)
65 is a rocket altimeter that is both precise and tiny, designed to be the
66 ideal altimeter for model rocket contests.
68 * [MicroPeak USB Interface](MicroPeakUSB/)
69 provides an interface between [MicroPeak](MicroPeak/) and USB to
70 download flight log data.
74 These are projects we're working on that may become products someday:
77 is the name of the firmware and related utilities that Keith maintains for
78 the set of hardware projects here.
80 * [MegaDongle](MegaDongle/)
81 is a higher-performance alternative to [TeleDongle](TeleDongle/).
83 * [TeleMega](TeleMega/)
84 is a high-end flight computer with 6 pyro channels, more and better sensors,
85 GPS, and a high performance bidirectional RF telemetry link.
88 was Bdale's original project here, a dual-deploy rocketry altimeter. One
89 prototype was built, but never flown. This project is now indefinitely on hold.
91 * [TeleNano](TeleNano/)
92 is a tiny rocketry altimeter with telemetry using only a barometric
95 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
96 that adds 8 additional pyro channels.
98 * [TeleScience](TeleScience/) is a companion board for
99 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
100 analog sensor input, and 5 general purpose I/O lines.
102 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
104 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
105 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

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

137 If you aren't already playing with model rockets, that's a good place to
138 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
139 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
140 learn a lot and see some great flights by showing up at a club launch.
142 As we make progress, you can read about it in our [News](News) feed. Feel
143 free to subscribe to our
144 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
145 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
146 questions that aren't answered here. You can also find us on
147 [Facebook](http://www.facebook.com/group.php?gid=341167482968)
149 [Google+](https://plus.google.com/109995815990298399569).
151 Our main projects include radio links. If you don't already have one,
152 getting an [Amateur Radio](./Radio) license would be a good thing to do!
154 And if you just can't wait to show your support for our efforts, visit
155 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
156 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
157 to decide which is better, comments welcome!) and buy a t-shirt or sticker!

162 Altus Metrum products are designed and manufactured in the
163 United States of America.
