Rockets we know of flying with TeleMetrum boards have exceeded 50g acceleration,
been well above Mach 1, and reached altitudes
greater than 25k feet AGL with great results. Keith's second generation

and logs telemetry to disk, displays current and max values for key parameters
during flight, includes voice synthesis during the flight so that
our eyes can stay on the rockets, and even includes live display of rocket
programs or other analysis tools allowing you to perform whatever
custom analysis you can envision! More details on the software,

## Future Plans ##
-TeleMetrum v1.1 meets all of our expectations, except for one mis-placed
-trace also present in v1.0. The error makes use of a separate pyro battery
-less trivial than intended. We'll fix that for a future production run.
+TeleMetrum v1.2 is now out for production. The significant user-visible
+change is that we've moved to a 70g accelerometer by default, due to poor
+availability of the part we previously used due to damage to the Freescale
+facility in Sendai caused by the Japan earthquake / tsunami. Boards should
+be in stock again shortly before Christmas 2011, and full details will be
+posted here at that time.
## Problems ##
place parts! Without an inspection microscope, loading and testing these
boards might be impossible.

can exceed the rate at which we draw power from the USB interface,
particularly when the GPS is in cold start mode. This means a battery must
be attached during operation, and also that the battery will only charge
