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
82 Android devices, or a compatible iOS application available for sale from
83 our friends at [Iron Sheep Productions](http://altosui.ironsheep.biz/).
86 is a GPS tracker and logger using the uBlox Max 7Q GPS receiver for
87 high dynamic performance and a combination digital/APRS transmitter.
89 * [LipoCharger](LipoCharger/)
90 is a standalone battery charger for the Lithium Polymer batteries used in
91 Altus Metrum products.
93 * [MicroPeak](MicroPeak/)
94 is a rocket altimeter that is both precise and tiny, designed to be the
95 ideal altimeter for model rocket contests.
97 * [MicroPeak USB Interface](MicroPeakUSB/)
98 provides an interface between [MicroPeak](MicroPeak/) and USB to
99 download flight log data.
101 * [ChaosKey](ChaosKey/)
102 is a true hardware random number generator that connects over USB.
106 These are projects we're working on that may become products someday:
109 is the name of the firmware and related utilities that Keith maintains for
110 the set of hardware projects here.
112 * [AltosDroid](AltosDroid/)
113 is the name of our Android app based on AltOS.
115 * [OpenAlt](OpenAlt/)
116 was Bdale's original project here, a dual-deploy rocketry altimeter. One
117 prototype was built, but never flown.
119 * [TeleLaunch](TeleLaunch/)
120 is a wireless launch control system capable of operating up to 792 pads.
122 * [TeleStatic](TeleStatic/)
123 is a wireless system for operating rocket motor test stands.
125 * [TeleNano](TeleNano/)
126 is a tiny rocketry altimeter with telemetry using only a barometric
129 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
130 that adds 8 additional pyro channels.
132 * [TeleScience](TeleScience/) is a companion board for
133 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
134 analog sensor input, and 5 general purpose I/O lines.
136 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
138 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
139 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

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

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

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