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 * [LipoCharger](LipoCharger/)
57 is a standalone battery charger for the Lithium Polymer batteries used in
58 Altus Metrum products.
60 * [MicroPeak](MicroPeak/)
61 is a rocket altimeter that is both precise and tiny, designed to be the
62 ideal altimeter for model rocket contests.
64 * [MicroPeak USB Interface](MicroPeakUSB/)
65 provides an interface between [MicroPeak](MicroPeak/) and USB to
66 download flight log data.
70 These are projects we're working on that may become products someday:
73 is the name of the firmware and related utilities that Keith maintains for
74 the set of hardware projects here.
76 * [MegaDongle](MegaDongle/)
77 is a higher-performance alternative to [TeleDongle](TeleDongle/).
79 * [MegaMetrum](MegaMetrum/)
80 is a high-end flight computer with 6 pyro channels, more and better sensors,
81 GPS, and a high performance bidirectional RF telemetry link.
84 was Bdale's original project here, a dual-deploy rocketry altimeter. One
85 prototype was built, but never flown. This project is now indefinitely on hold.
87 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
88 [Bluetooth](http://www.bluetooth.com) as an alternative to USB.
90 * [TeleNano](TeleNano/)
91 is a tiny rocketry altimeter with telemetry using only a barometric
94 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
95 that adds 8 additional pyro channels.
97 * [TeleScience](TeleScience/) is a companion board for
98 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
99 analog sensor input, and 5 general purpose I/O lines.
101 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
103 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
104 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).
108 The motivation for the circuits and software you will find on this site is
109 our loosely-knit group's shared interest in hobby rocketry. This very brief
110 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
111 quickly conveys at least part of why we do this. John Coker
112 has published an excellent
113 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
114 on his web site. Keith has also put together some useful notes about the
115 process of [certification](http://keithp.com/rockets/certification/) to
116 fly high power rockets.
118 To find more information about the rockets Bdale and his son have built, see
119 [Garbee Rockets](http://www.gag.com/rockets).
121 As Bdale and Robert became more experienced in the hobby and started to build
122 and fly more sophisticated projects, we started to feel limited by the
123 existing electronics products available. OpenAlt was Bdale's first
124 attempt to address this situation with a completely open hardware and software
125 design... other project have since followed, and it's cool to have help from
126 Keith and other friends!

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