39 * [Rebel Space](http://rebelspace.eu)
41 * [Aerospace Education](http://www.rockets.co.nz)
43 For ChaosKey, there is a distributor in Europe:
45 * [Vikings GmbH](https://store.vikings.net/accessories)
49 These products are available for purchase:
51 * [TeleMetrum](TeleMetrum/)
52 is our flagship product, a dual-deploy rocketry altimeter with
53 GPS and bidirectional RF telemetry link.
55 * [TeleMega](TeleMega/)
56 is a high-end flight computer with 6 pyro channels, tilt limits, more and
57 better sensors, GPS, and a high performance bidirectional RF telemetry link.
59 * [TeleMini](TeleMini/)
60 is a smaller dual-deploy rocketry altimeter with telemetry using only a
61 barometric pressure sensor
63 * [EasyMega](EasyMega/)
64 is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
65 design is identical to [TeleMega](TeleMega/), but without the GPS receiver
66 and radio telemetry link.
68 * [EasyMini](EasyMini/)
69 is a small dual-deploy rocketry altimeter using the MS5607 barometry
72 * [TeleDongle](TeleDongle/)
73 is a simple RF interface for use in ground stations interacting with rockets
74 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
75 interface for other microcontroller systems. Note that we don't actually
76 sell TeleDongle by itself, it is included in our
77 [Starter Pack](http://shop.gag.com/ground-stations/starter-pack.html) offering.
79 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
80 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
81 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for Android devices!
84 is a GPS tracker and logger using the uBlox Max 7Q GPS receiver for
85 high dynamic performance and a combination digital/APRS transmitter.
87 * [LipoCharger](LipoCharger/)
88 is a standalone battery charger for the Lithium Polymer batteries used in
89 Altus Metrum products.
91 * [MicroPeak](MicroPeak/)
92 is a rocket altimeter that is both precise and tiny, designed to be the
93 ideal altimeter for model rocket contests.
95 * [MicroPeak USB Interface](MicroPeakUSB/)
96 provides an interface between [MicroPeak](MicroPeak/) and USB to
97 download flight log data.
99 * [ChaosKey](ChaosKey/)
100 is a true hardware random number generator that connects over USB.
104 These are projects we're working on that may become products someday:
107 is the name of the firmware and related utilities that Keith maintains for
108 the set of hardware projects here.
110 * [OpenAlt](OpenAlt/)
111 was Bdale's original project here, a dual-deploy rocketry altimeter. One
112 prototype was built, but never flown.
114 * [TeleLaunch](TeleLaunch/)
115 is a wireless launch control system capable of operating up to 400 pads.
117 * [TeleNano](TeleNano/)
118 is a tiny rocketry altimeter with telemetry using only a barometric
121 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
122 that adds 8 additional pyro channels.
124 * [TeleScience](TeleScience/) is a companion board for
125 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
126 analog sensor input, and 5 general purpose I/O lines.
128 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
130 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
131 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

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

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