74 barometric pressure sensor
76 * [EasyMega](EasyMega/)
77 is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
78 design is essentially identical to [TeleMega](TeleMega/), but without the

89 is a simple USB to RF interface for use in ground stations interacting with
90 rockets using any of our products with RF telemetry.
92 * [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
93 [Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
94 useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for
95 Android devices, or the compatible iOS application available for sale from
96 our friends at [Iron Sheep Productions](http://altosui.ironsheep.biz/).
99 is a GPS tracker and logger.
101 * [TeleLaunch](TeleLaunch/)
102 is a wireless launch control system capable of operating up to 792 pads.

105 is a standalone battery charger for the Lithium Polymer batteries used in
106 Altus Metrum products.
108 * [MicroPeak](MicroPeak/)
109 is a rocket altimeter that is both precise and tiny, designed to be the
110 ideal altimeter for model rocket contests.
112 * [MicroPeak USB Interface](MicroPeakUSB/)
113 provides an interface between [MicroPeak](MicroPeak/) and USB to
114 download flight log data.
118 These are projects we're working on that may become products someday:
121 is the name of the firmware and related utilities that Keith maintains for
122 the set of hardware projects here.
124 * [AltosDroid](AltosDroid/)
125 is the name of our Android app based on AltOS.
127 * [ChaosKey](ChaosKey/)
128 is a true hardware random number generator that connects over USB.
130 * [EasyMotor](EasyMotor/)
131 is an in-flight data logger for research motor characterization.
133 * [OpenAlt](OpenAlt/)
134 was Bdale's original project here, a dual-deploy rocketry altimeter. One
135 prototype was built, but never flown.
137 * [TeleStatic](TeleStatic/)
138 is a wireless system for operating rocket motor test stands.
140 * [TeleNano](TeleNano/)
141 is a tiny rocketry altimeter with telemetry using only a barometric
144 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
145 that adds 8 additional pyro channels.
147 * [TeleScience](TeleScience/) is a companion board for
148 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
149 analog sensor input, and 5 general purpose I/O lines.
151 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.

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

188 If you aren't already playing with model rockets, that's a good place to
189 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
190 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
191 learn a lot and see some great flights by showing up at a club launch.
193 As we make progress, you can read about it in our [News](News) feed. Feel
194 free to subscribe to our
195 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
196 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
197 questions that aren't answered here. You can also find us on
198 [Facebook](http://www.facebook.com/group.php?gid=341167482968), though note
199 we don't check Facebook very often.
201 Our main projects include radio links. If you don't already have one,
202 getting an [Amateur Radio](./Radio) license would be a good thing to do!
204 And if you just can't wait to show your support for our efforts, visit
