21 * [TeleMetrum](TeleMetrum/)
22 is our primary project, a dual-deploy rocketry altimeter with
23 GPS and bidirectional RF telemetry link.
25 * [TeleDongle](TeleDongle/)
26 is a simple RF interface for use in ground stations interacting with rockets
27 using [TeleMetrum](TeleMetrum/). It may also be useful as a generic RF
28 interface for other microcontroller systems.
30 * [TeleMini](TeleMini/)
31 is a smaller dual-deploy rocketry altimeter with telemetry using only a
32 barometric pressure sensor
34 * [TeleNano](TeleNano/)
35 is a tiny rocketry altimeter with telemetry using only a barometric
39 is the name of the firmware and related utilities that Keith maintains for
40 the set of hardware projects here.
42 * [TelePyro](TelePyro/) is a planned 8-channel pyro expansion board for
43 [TeleMetrum](TeleMetrum/).
45 * [TeleScience](TeleScience/) is a planned expansion board for
46 [TeleMetrum](TeleMetrum/) providing 12 channels of thermistor or generic
47 analog sensor input, and 5 general purpose I/O lines.
49 * [TeleTerra](TeleTerra) is a planned hand-held ground station for use with
50 [TeleMetrum](TeleMetrum/).
53 was Bdale's original project here, a dual-deploy rocketry altimeter. One
54 prototype was built, but never flown. This project is now indefinitely on hold.

62 If you aren't already playing with model rockets, that's a good place to
63 start. Finding a local [NAR Section](http://nar.org/NARsect.html) or
64 [Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
65 learn a lot and see some great flights by showing up at a club launch.
67 As we make progress, you can read about it in our [News](News) feed. Feel
68 free to subscribe to our
69 [mailing list](http://lists.gag.com/mailman/listinfo/altusmetrum). We also
70 hang out on IRC channel #altusmetrum on irc.oftc.net if you have
71 questions that aren't answered here. And if you're a Facebook user, you
72 can join the [Altus Metrum](http://www.facebook.com/group.php?gid=341167482968)
75 Our main projects include radio links. If you don't already have one,
76 getting an [Amateur Radio](./Radio) license would be a good thing to do!
78 And if you just can't wait to show your support for our efforts, visit
79 our [Cafe Press Logo Shop](http://cafepress.com/altusmetrum) or our
80 [Printfection Logo Shop](http://printfection.com/altusmetrum) (we're trying
81 to decide which is better, comments welcome!) and buy a t-shirt or sticker!
