22 All Altus Metrum products are available from the
23 [Garbee and Garbee](http://auric.gag.com) web
24 store. [Apogee Components](http://www.apogeerockets.com) carries both
25 [TeleMetrum](http://www.apogeerockets.com/Altus_Metrum_GPS.asp) and
26 [TeleMini](http://www.apogeerockets.com/Altus_Metrum_telemini.asp) starter
27 kits. [Australian Rocketry](http://www.ausrocketry.com) carries [TeleMetrum](http://www.ausrocketry.com/shop/index.php?main_page=product_info&cPath=111&products_id=4302) starter kits.
31 * [TeleMetrum](TeleMetrum/)
32 is our flagship product, a dual-deploy rocketry altimeter with
33 GPS and bidirectional RF telemetry link.
35 * [TeleMini](TeleMini/)
36 is a smaller dual-deploy rocketry altimeter with telemetry using only a
37 barometric pressure sensor
39 * [TeleDongle](TeleDongle/)
40 is a simple RF interface for use in ground stations interacting with rockets
41 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
42 interface for other microcontroller systems.
45 is the name of the firmware and related utilities that Keith maintains for
46 the set of hardware projects here.
48 * [LipoCharger](LipoCharger/)
49 is a standalone battery charger for the Lithium Polymer batteries used in
50 Altus Metrum products.
52 * [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
53 that adds 8 additional pyro channels.
55 * [TeleScience](TeleScience/) is a companion board for
56 [TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
57 analog sensor input, and 5 general purpose I/O lines.
59 * [TeleTerra](TeleTerra) is a hand-held ground station for use with
60 [TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).
62 * [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
64 * [TeleNano](TeleNano/)
65 is a tiny rocketry altimeter with telemetry using only a barometric
69 was Bdale's original project here, a dual-deploy rocketry altimeter. One
70 prototype was built, but never flown. This project is now indefinitely on hold.
74 The motivation for the circuits and software you will find on this site is
75 our loosely-knit group's shared interest in hobby rocketry. This very brief
76 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
77 quickly conveys at least part of why we do this. John Coker
78 has published an excellent
79 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
80 on his web site. Keith has also put together some useful notes about the
81 process of [certification](http://keithp.com/rockets/certification/) to
82 fly high power rockets.
84 To find more information about the rockets Bdale and his son have built, see
85 [Garbee Rockets](http://www.gag.com/rockets).
87 As Bdale and Robert became more experienced in the hobby and started to build
88 and fly more sophisticated projects, we started to feel limited by the
89 existing electronics products available. OpenAlt was Bdale's first
90 attempt to address this situation with a completely open hardware and software
91 design... other project have since followed, and it's cool to have help from
92 Keith and other friends!

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

114 Our main projects include radio links. If you don't already have one,
115 getting an [Amateur Radio](./Radio) license would be a good thing to do!
117 And if you just can't wait to show your support for our efforts, visit
118 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
119 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
120 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
