41 For ChaosKey, there is a distributor in Europe:
43 * [Vikings GmbH](https://store.vikings.net)
47 These products are available for purchase:
49 * [TeleMetrum](TeleMetrum/)
50 is our flagship product, a dual-deploy rocketry altimeter with
51 GPS and bidirectional RF telemetry link.
53 * [TeleMega](TeleMega/)
54 is a high-end flight computer with 6 pyro channels, tilt limits, more and
55 better sensors, GPS, and a high performance bidirectional RF telemetry link.
57 * [TeleMini](TeleMini/)
58 is a smaller dual-deploy rocketry altimeter with telemetry using only a
59 barometric pressure sensor
61 * [EasyMega](EasyMega/)
62 is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
63 design is identical to [TeleMega](TeleMega/), but without the GPS receiver
64 and radio telemetry link.
66 * [EasyMini](EasyMini/)
67 is a small dual-deploy rocketry altimeter using the MS5607 barometry
70 * [TeleDongle](TeleDongle/)
71 is a simple RF interface for use in ground stations interacting with rockets
72 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
73 interface for other microcontroller systems. Note that we don't actually
74 sell TeleDongle by itself, it is included in our
75 [Starter Pack](http://shop.gag.com/ground-stations/starter-pack.html) offering.
77 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
78 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
79 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for
80 Android devices, or a compatible iOS application available for sale from
81 our friends at [Iron Sheep Productions](http://altosui.ironsheep.biz/).
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 * [AltosDroid](AltosDroid/)
111 is the name of our Android app based on AltOS.
113 * [EasyMotor](EasyMotor/)
114 is an in-flight data logger for research motor characterization.
116 * [OpenAlt](OpenAlt/)
117 was Bdale's original project here, a dual-deploy rocketry altimeter. One
118 prototype was built, but never flown.
120 * [TeleLaunch](TeleLaunch/)
121 is a wireless launch control system capable of operating up to 792 pads.
123 * [TeleStatic](TeleStatic/)
124 is a wireless system for operating rocket motor test stands.
126 * [TeleNano](TeleNano/)
127 is a tiny rocketry altimeter with telemetry using only a barometric
130 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
131 that adds 8 additional pyro channels.
133 * [TeleScience](TeleScience/) is a companion board for
134 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
135 analog sensor input, and 5 general purpose I/O lines.
137 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
139 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
140 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

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

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

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