-# TeleMetrum Units
-
-This page contains Bdale's notes about each unit of [TeleMetrum](..)
-assembled to date.
-
-## sn 1 ##
-
-Full load of v0.1 PCB, two cuts and jumps to rewire P1_2 to be SPI memory
-chip select, R14 and R15 loaded with 56k, 10k tacked from each to
-ground. R17 replaced with short circuit, R18 removed.
-
-Installed in Bdale's Vertical Assault. First unit to be flown on
-2009.04.19, on a Cesaroni J335.
-
-Successfully flew Bdale's rebuilt Horizon dual-deploy at Hudson Ranch on
-2009.07.18 with a MAWD as backup. The first dual-deploy flight with a TM
-board in control of ejection charges!

-
-Full load of v0.1 PCB, two cuts and jumps to rewire P1_2 to be SPI memory
-chip select, R14 and R15 loaded with 56k, 10k tacked from each to
-ground.
-
-Delivered to Keith Packard for firmware development and use. Flown twice
-on 10 May 2008 in Keith's Grappler to about 45m on Estes D12-3 motors.
-
-Flew in Keith's Little Dog Dual Deploy at Mile High Mayhem as a payload. The
-ascent was pretty but the rocket failed to deploy and lawn-darted. The battery
-and screw terminal block connectors got more or less torn off, but the rest
-of the board survived and good data was recovered from the flight.
-
-Repaired by Bdale, sent back to Keith on 7 July 2009. Keith reported the
-baro sensor as flakey, it was replaced in October 2009 prior to
-NCR Octoberfest.

-Full load of v0.1 PCB on 2009.04.22, two cuts and jumps to rewire P1_2
-to be SPI memory chip select, R14 and R15 loaded with 100k, 27k tacked
-from each to ground.
-
-Installed in Bdale's Vertical Assault after sn 1 moved to Horizon, but never
-flown there.
-
-Pulled and given to Keith to take home from Mayhem.
-
-Lost in Keith's Nike which was lost for a while after an apparently nominal
-flight in June 2009 at Brothers, Oregon. Rocket was later found and this unit
-is reportedly still in good condition.

-
-Installed in Robert's Lil Nuke.
-
-Lost at Hudson Ranch 2009.07.18 when we forgot to tape the nose cone on and
-both it and the electronics sled came out at apogee and were not recovered.
-
-## sn 5 ##
-
-Partial "ground" load of v0.1 PCB on 2009.04.23 plus beeper and serial
-connector for use as TeleDongle or for TeleTerra prototype.
-
-Bdale's TeleDongle.
-
-Keith added acrylic LED light pipes and a LiPo for use in RDF after flight.

-to be SPI memory chip select, R14 and R15 loaded with 100k, 27k tacked
-from each to ground.
-
-Pulled from Vertical Assault (never flew there) and taken to Keith in Japan
-in October 2009 as replacement.

-to be SPI memory chip select, R14 and R15 loaded with 100k, 27k tacked
-from each to ground. Accelerometer loaded is MMA2204EG 100G unit!
-
-In G-Spot, this accelerometer recorded 52.8 gee acceleration on a
-Cesaroni pro29 H399 reload at NCR Oktoberfest 2009!
-
-Beeper failed after a hard landing, replaced 2010.02.06.

-from each to ground.
-
-Modified 2009.11.20 to:
-
-* use TC1055-3.3VCT713 100ma regulator proposed for v0.2
-* route 3.3V instead of v_lipo to the serial connector for SkyTraq GPS
-* use v_lipo for pyro voltage instead of 5V with 1000uF capacitor
-* added 100uF 1206 capacitor on 3.3V rail
-
-In this configuration, flew two textbook perfect flights on 2009.11.21 at
-Hudson Ranch in Trick-O-Treat on J motors.
