This board is designed for in-flight characterization of research rocket
motors. It records chamber pressure and acceleration to an on-board flash
memory chip, the contents of which can be downloaded after flight over USB.
-It can also be attached to a [TeleMetrum](../TeleMetrum) or
-[TeleMega](../TeleMega) using the companion interface to allow a subset of
-the data to be included in radio telemetry during the flight.
-There is no EasyMotor firmware yet, but it will be part of the
-[AltOS](../AltOS) suite eventually.
+EasyMotor firmware is under development within the [AltOS](../AltOS) suite.
-Prototypes of v1 were built and evaluated, prototypes of v2 are
-underway. This design is not yet for sale, but we hope to have it on the
-market by mid-summer 2020.

## Features ##
* the 3-axis accelerometer has a max scale of +/- 6g. This is insufficient
for characterizing the kinds of motors that we're playing with now.
-* while using a gcc-based toolchain to cross-develop for the ARM7 core works
- reasonably well, it's a heavy toolchain to build and maintain, and the
- processor really is serious overkill for the task at hand.

## Artifacts ##

The version 0.1 design had enough issues that Bdale decided not to publish
-it. Work on an 0.2 revision is mostly complete at the schematic level, and

## Availability ##
-A prototype system was operated extensively during the 2017, and based
-on that experience a revised version of the circuit board was designed
-and will be tested eventually. General availability of the TeleStatic
-product is expected by the end of calendar 2018. Watch this space for
-updates on price and availability.
+A prototype system was developed in 2017, and has been in routine use
+ever since. The electronics has been through at least three major
+revisions, none of which have yet made it into production. A "final"
+version is being worked on based on everything learned so far, and
+we hope to have it for sale by the end of calendar 2020. Watch this
+space for updates.
