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

95 If you aren't already playing with model rockets, that's a good place to
96 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
97 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
98 learn a lot and see some great flights by showing up at a club launch.
100 As we make progress, you can read about it in our [News](News) feed. Feel
101 free to subscribe to our
102 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
103 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
104 questions that aren't answered here. And if you're a Facebook user, you
105 can join the [Altus Metrum](http://www.facebook.com/group.php?gid=341167482968)
108 Our main projects include radio links. If you don't already have one,
109 getting an [Amateur Radio](./Radio) license would be a good thing to do!
111 And if you just can't wait to show your support for our efforts, visit
112 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
113 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
114 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
118 ![United States flag](USflag.png)
119 Altus Metrum products are designed and manufactured in the
120 United States of America.
