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 * [TeleDongle](TeleDongle/)
59 is a simple RF interface for use in ground stations interacting with rockets
60 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
61 interface for other microcontroller systems. Note that we don't actually
62 sell TeleDongle by itself, it is included in our
63 [Starter Pack](http://shop.gag.com/ground-stations/starter-pack.html) offering.
65 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
66 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
67 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for Android devices!
70 is a GPS tracker and logger using the uBlox Max 7Q GPS receiver for
71 high dynamic performance and a combination digital/APRS transmitter.
73 * [EasyMega](EasyMega/)
74 is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
75 design is identical to [TeleMega](TeleMega/), but without the GPS receiver
76 and radio telemetry link.
78 * [EasyMini](EasyMini/)
79 is a small dual-deploy rocketry altimeter using the MS5607 barometry
82 * [LipoCharger](LipoCharger/)
83 is a standalone battery charger for the Lithium Polymer batteries used in
84 Altus Metrum products.
86 * [MicroPeak](MicroPeak/)
87 is a rocket altimeter that is both precise and tiny, designed to be the
88 ideal altimeter for model rocket contests.
90 * [MicroPeak USB Interface](MicroPeakUSB/)
91 provides an interface between [MicroPeak](MicroPeak/) and USB to
92 download flight log data.
94 * [ChaosKey](ChaosKey/)
95 is a true hardware random number generator that connects over USB.
97 The following product is available in limited quantity from time to time:
99 * [TeleMini](TeleMini/)
100 is a smaller dual-deploy rocketry altimeter with telemetry using only a
101 barometric pressure sensor
105 These are projects we're working on that may become products someday:
108 is the name of the firmware and related utilities that Keith maintains for
109 the set of hardware projects here.
111 * [OpenAlt](OpenAlt/)
112 was Bdale's original project here, a dual-deploy rocketry altimeter. One
113 prototype was built, but never flown. This project is now indefinitely on hold.
115 * [TeleLaunch](TeleLaunch/)
116 is a wireless launch control system capable of operating up to 400 pads.
118 * [TeleNano](TeleNano/)
119 is a tiny rocketry altimeter with telemetry using only a barometric
122 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
123 that adds 8 additional pyro channels.
125 * [TeleScience](TeleScience/) is a companion board for
126 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
127 analog sensor input, and 5 general purpose I/O lines.
129 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
131 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
132 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).
134 * [ChaosKey](ChaosKey) is a USB-attached True Random Number Generator

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

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

181 Our main projects include radio links. If you don't already have one,
182 getting an [Amateur Radio](./Radio) license would be a good thing to do!
