+# Products #
+
+These products are available for purchase:
+
+* [TeleMetrum](TeleMetrum/)
+was our original (and still our most popular!) product, a dual-deploy rocketry
+altimeter with GPS and RF telemetry link.
+
+* [TeleMega](TeleMega/)
+is a high-end flight computer with 6 pyro channels, tilt limits, more and
+better sensors, GPS, and RF telemetry link.
+
+* [TeleMini](TeleMini/)
+is our smallest dual-deploy rocketry altimeter with telemetry using only a
+barometric pressure sensor
+
+* [EasyMega](EasyMega/)
+is a high-end flight computer with 6 pyro channels, tilt limits, etc. The
+design is essentially identical to [TeleMega](TeleMega/), but without the
+GPS receiver and radio telemetry link.
+
+* [EasyMini](EasyMini/)
+is a small, low-cost, dual-deploy rocketry altimeter using just a barometry
+pressure sensor.
+
+* [EasyMotor](EasyMotor/)
+is an in-flight data logger for research motor characterization.
+
+* [EasyTimer](EasyTimer/)
+is a timer-based 2-channel pyro controller with tilt limits
+
+* [TeleDongle](TeleDongle/)
+is a simple USB to RF interface for use in ground stations interacting with
+rockets using any of our products with RF telemetry.
+
+* [TeleBT](TeleBT) is a variation on [TeleDongle](TeleDongle/) that adds
+[Bluetooth](http://www.bluetooth.com) as an alternative to USB. Particularly
+useful with the [AltosDroid](http://www.altusmetrum.org/AltosDroid/) app for
+Android devices, or the compatible iOS application available for sale from
+our friends at [Iron Sheep Productions](http://altosui.ironsheep.biz/).
+
+* [TeleGPS](TeleGPS/)
+is a GPS tracker and logger.
+
+* [TeleLaunch](TeleLaunch/)
+is a wireless launch control system capable of operating up to 792 pads.
+
+* [LipoCharger](LipoCharger/)
+is a standalone battery charger for the Lithium Polymer batteries used in
+Altus Metrum products.
+
+* [MicroPeak](MicroPeak/)
+is a rocket altimeter that is both precise and tiny, designed to be the
+ideal altimeter for model rocket contests.
+
+* [MicroPeak USB Interface](MicroPeakUSB/)
+provides an interface between [MicroPeak](MicroPeak/) and USB to
+download flight log data.
+
+# Projects #
+
+These are projects we're working on that may become products someday:
+
+* [AltOS](AltOS/)
+is the name of the firmware and related utilities that Keith maintains for
+the set of hardware projects here.
+
+* [AltosDroid](AltosDroid/)
+is the name of our Android app based on AltOS.
+
+* [ChaosKey](ChaosKey/)
+is a true hardware random number generator that connects over USB.
+
+* [OpenAlt](OpenAlt/)
+was Bdale's original project here, a dual-deploy rocketry altimeter. One
+prototype was built, but never flown.
+
+* [QuantiMotor](QuantiMotor/)
+is a wireless system for operating rocket motor test stands.
+
+* [TeleNano](TeleNano/)
+is a tiny rocketry altimeter with telemetry using only a barometric
+pressure sensor
+
+* [TelePyro](TelePyro/) is a companion board for [TeleMetrum](TeleMetrum/)
+that adds 8 additional pyro channels.
+
+* [TeleScience](TeleScience/) is a companion board for
+[TeleMetrum](TeleMetrum/) that adds 12 channels of thermistor or generic
+analog sensor input, and 5 general purpose I/O lines.
+
+* [TeleShield](TeleShield/) is an [Arduino](http://arduino.cc) radio shield.
+
+* [TeleTerra](TeleTerra) is a hand-held ground station for use with
+[TeleMetrum](TeleMetrum/) and [TeleMini](TeleMini/).

# Hobby Rocketry #
The motivation for the circuits and software you will find on this site is
-our loosely-knit group's shared interest in hobby rocketry.
-Rather than try to introduce the hobby to you here, we note that John Coker
+our loosely-knit group's shared interest in hobby rocketry. This very brief
+[Ted presentation by Steve Jurvetson](http://www.ted.com/talks/steve_jurvetson_on_model_rocketry.html)
+quickly conveys at least part of why we do this. John Coker
has published an excellent
[overview of hobby rocketry](http://www.jcrocket.com/welcome.shtml)
-on his web site.
+on his web site. Keith has also put together some useful notes about the
+process of [certification](http://keithp.com/rockets/certification/) to
+fly high power rockets. And thanks to Maddie for pointing out the paghes that
+[Lisa Richards](http://www.mapcon.com/model-rocket-maintenance-technology) maintains.

As Bdale and Robert became more experienced in the hobby and started to build
and fly more sophisticated projects, we started to feel limited by the
-existing electronics products available. AltusMetrum was Bdale's first
+existing electronics products available. OpenAlt was Bdale's first
attempt to address this situation with a completely open hardware and software
-design... other project have since followed!
-
-# Projects #
-
-* [AltusMetrum](AltusMetrum/)
-was Bdale's original project here, a dual-deploy rocketry altimeter. One
-prototype was built, but never flown. This project is now indefinitely on hold.
-
-* [TeleMetrum](TeleMetrum/)
-is our current project, a dual-deploy rocketry altimeter with improved sensor
-complement and bidirectional RF telemetry link.
+design... other project have since followed, and it's cool to have help from
+Keith and other friends!

# Getting Involved #
[Tripoli](http://tripoli.org) Prefecture is a good idea, since you can
learn a lot and see some great flights by showing up at a club launch.
-As we make progress, you can read about it in our [News](News/) feed.
-We also have an IRC channel #altusmetrum on irc.oftc.net if you have
-questions that aren't answered here.
+As we make progress, you can read about it in our [News](News) feed. Feel
+free to subscribe to our
+[mailing list](https://groups.io/g/altusmetrum). We also hang out on
+IRC channel #altusmetrum on irc.oftc.net if you have

+we don't check Facebook very often.
+
+Our main projects include radio links. If you don't already have one,
+getting an [Amateur Radio](./Radio) license would be a good thing to do!
