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

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

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

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