26 Altus Metrum products are available directly from
27 [Bdale's web store](https://shop.gag.com), and from these distributors:
30 * [Apogee Components](http://www.apogeerockets.com)
31 * [Bay Area Rocketry](http://bayarearocketry.com)
32 * [Chris' Rocket Supplies](http://csrocketry.com)
34 * [Australian Rocketry](http://www.ausrocketry.com)
36 * [SierraFoxHobbies](http://www.sierrafoxhobbies.com)
38 * [Rebel Space](http://rebelspace.eu)
40 * [Aerospace Education](http://www.rockets.co.nz)
42 For ChaosKey, there is a distributor in Europe:
44 * [Vikings GmbH](https://store.vikings.net/libre-friendly-accessories)
48 These products are available for purchase:
50 * [TeleMetrum](TeleMetrum/)
51 is our flagship product, a dual-deploy rocketry altimeter with
52 GPS and bidirectional RF telemetry link.
54 * [TeleMega](TeleMega/)
55 is a high-end flight computer with 6 pyro channels, tilt limits, more and
56 better sensors, GPS, and a high performance bidirectional RF telemetry link.
58 * [TeleMini](TeleMini/)
59 is a smaller dual-deploy rocketry altimeter with telemetry using only a
60 barometric pressure sensor
62 * [EasyMega](EasyMega/)
63 is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
64 design is identical to [TeleMega](TeleMega/), but without the GPS receiver
65 and radio telemetry link.
67 * [EasyMini](EasyMini/)
68 is a small dual-deploy rocketry altimeter using the MS5607 barometry
71 * [TeleDongle](TeleDongle/)
72 is a simple RF interface for use in ground stations interacting with rockets
73 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
74 interface for other microcontroller systems. Note that we don't actually
75 sell TeleDongle by itself, it is included in our
76 [Starter Pack](http://shop.gag.com/ground-stations/starter-pack.html) offering.
78 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
79 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
80 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for Android devices!
83 is a GPS tracker and logger using the uBlox Max 7Q GPS receiver for
84 high dynamic performance and a combination digital/APRS transmitter.
86 * [LipoCharger](LipoCharger/)
87 is a standalone battery charger for the Lithium Polymer batteries used in
88 Altus Metrum products.
90 * [MicroPeak](MicroPeak/)
91 is a rocket altimeter that is both precise and tiny, designed to be the
92 ideal altimeter for model rocket contests.
94 * [MicroPeak USB Interface](MicroPeakUSB/)
95 provides an interface between [MicroPeak](MicroPeak/) and USB to
96 download flight log data.
98 * [ChaosKey](ChaosKey/)
99 is a true hardware random number generator that connects over USB.
103 These are projects we're working on that may become products someday:
106 is the name of the firmware and related utilities that Keith maintains for
107 the set of hardware projects here.
109 * [OpenAlt](OpenAlt/)
110 was Bdale's original project here, a dual-deploy rocketry altimeter. One
111 prototype was built, but never flown.
113 * [TeleLaunch](TeleLaunch/)
114 is a wireless launch control system capable of operating up to 400 pads.
116 * [TeleNano](TeleNano/)
117 is a tiny rocketry altimeter with telemetry using only a barometric
120 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
121 that adds 8 additional pyro channels.
123 * [TeleScience](TeleScience/) is a companion board for
124 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
125 analog sensor input, and 5 general purpose I/O lines.
127 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
129 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
130 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

136 The motivation for the circuits and software you will find on this site is
137 our loosely-knit group's shared interest in hobby rocketry. This very brief
138 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
139 quickly conveys at least part of why we do this. John Coker
140 has published an excellent
141 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
142 on his web site. Keith has also put together some useful notes about the
143 process of [certification](http://keithp.com/rockets/certification/) to
144 fly high power rockets. And thanks to Maddie for pointing out the paghes that
145 [Lisa Richards](http://www.mapcon.com/model-rocket-maintenance-technology) maintains.
147 To find more information about the rockets Bdale and his son have built, see
148 [Garbee Rockets](http://www.gag.com/rockets).
150 As Bdale and Robert became more experienced in the hobby and started to build
151 and fly more sophisticated projects, we started to feel limited by the
152 existing electronics products available. OpenAlt was Bdale's first
153 attempt to address this situation with a completely open hardware and software
154 design... other project have since followed, and it's cool to have help from
155 Keith and other friends!

163 If you aren't already playing with model rockets, that's a good place to
164 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
165 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
166 learn a lot and see some great flights by showing up at a club launch.
168 As we make progress, you can read about it in our [News](News) feed. Feel
169 free to subscribe to our
170 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
171 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
172 questions that aren't answered here. You can also find us on
173 [Facebook](http://www.facebook.com/group.php?gid=341167482968)
175 [Google+](https://plus.google.com/109995815990298399569).
177 Our main projects include radio links. If you don't already have one,
178 getting an [Amateur Radio](./Radio) license would be a good thing to do!
180 And if you just can't wait to show your support for our efforts, visit
