17 # Rocket Altimeters and Accessories
18 * [TeleMetrum](TeleMetrum/)
19 is our primary product, a dual-deploy rocketry altimeter with
20 GPS and bidirectional RF telemetry link.
22 * [TeleMini](TeleMini/)
23 is a smaller dual-deploy rocketry altimeter with telemetry using only a
24 barometric pressure sensor
28 * [TeleDongle](TeleDongle/)
29 is a simple RF interface for use in ground stations interacting with rockets
30 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
31 interface for other microcontroller systems.
36 is the name of the firmware and related utilities that Keith maintains for
37 the set of hardware projects here.

43 All Altus Metrum products are available from the
44 [Garbee and Garbee](http://auric.gag.com) web
45 store. [TeleMetrum](TeleMetrum/) starter kits are also available from
46 [Apogee Components](http://www.apogeerockets.com/Altus_Metrum_GPS.asp)
47 and [Australian Rocketry](http://www.ausrocketry.com/shop/index.php?main_page=product_info&cPath=111&products_id=4302).
51 The motivation for the circuits and software you will find on this site is
52 our loosely-knit group's shared interest in hobby rocketry. This very brief
53 [Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
54 quickly conveys at least part of why we do this. John Coker
55 has published an excellent
56 [overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
57 on his web site. Keith has also put together some useful notes about the
58 process of [certification](http://keithp.com/rockets/certification/) to
59 fly high power rockets.
61 To find more information about the rockets Bdale and his son have built, see
62 [Garbee Rockets](http://www.gag.com/rockets).
64 As Bdale and Robert became more experienced in the hobby and started to build
65 and fly more sophisticated projects, we started to feel limited by the
66 existing electronics products available. OpenAlt was Bdale's first
67 attempt to address this situation with a completely open hardware and software
68 design... other project have since followed, and it's cool to have help from
69 Keith and other friends!
73 * [TeleMetrum](TeleMetrum/)
74 is our primary project, a dual-deploy rocketry altimeter with
75 GPS and bidirectional RF telemetry link.
77 * [TeleDongle](TeleDongle/)
78 is a simple RF interface for use in ground stations interacting with rockets
79 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
80 interface for other microcontroller systems.
82 * [TeleMini](TeleMini/)
83 is a smaller dual-deploy rocketry altimeter with telemetry using only a
84 barometric pressure sensor
86 * [TeleNano](TeleNano/)
87 is a tiny rocketry altimeter with telemetry using only a barometric
91 is the name of the firmware and related utilities that Keith maintains for
92 the set of hardware projects here.
94 * [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for
95 [TeleMetrum](TeleMetrum/).
97 * [TeleScience](TeleScience/) is a planned expansion board for
98 [TeleMetrum](TeleMetrum/) providing 12 channels of thermistor or generic
99 analog sensor input, and 5 general purpose I/O lines.
101 * [TeleTerra](TeleTerra) is a planned hand-held ground station for use with
102 [TeleMetrum](TeleMetrum/).
104 * [OpenAlt](OpenAlt/)
105 was Bdale's original project here, a dual-deploy rocketry altimeter. One
106 prototype was built, but never flown. This project is now indefinitely on hold.

114 If you aren't already playing with model rockets, that's a good place to
115 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
116 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
117 learn a lot and see some great flights by showing up at a club launch.
119 As we make progress, you can read about it in our [News](News) feed. Feel
120 free to subscribe to our
121 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
122 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
123 questions that aren't answered here. And if you're a Facebook user, you
124 can join the [Altus Metrum](http://www.facebook.com/group.php?gid=341167482968)
127 Our main projects include radio links. If you don't already have one,
128 getting an [Amateur Radio](./Radio) license would be a good thing to do!
130 And if you just can't wait to show your support for our efforts, visit
131 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
132 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
133 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
137 
138 Altus Metrum products are designed and manufactured in the
139 United States of America.
