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

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

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