3 This page contains Bdale's notes about each unit of [TeleMetrum](TeleMetrum/)
4 and [TeleDongle](TeleDongle/) assembled to date.
8 Full load of v0.1 PCB, two cuts and jumps to rewire P1_2 to be SPI memory
9 chip select, R14 and R15 loaded with 56k, 10k tacked from each to
10 ground. R17 replaced with short circuit, R18 removed.
12 Installed in Bdale's Vertical Assault. First unit to be flown on
13 2009.04.19, on a Cesaroni J335.
15 Successfully flew Bdale's rebuilt Horizon dual-deploy at Hudson Ranch on
16 2009.07.18 with a MAWD as backup. The first dual-deploy flight with a TM
17 board in control of ejection charges!

25 Delivered to Keith Packard for firmware development and use. Flown twice
26 on 10 May 2008 in Keith's Grappler to about 45m on Estes D12-3 motors.
28 Flew in Keith's Little Dog Dual Deploy at Mile High Mayhem as a payload. The
29 ascent was pretty but the rocket failed to deploy and lawn-darted. The battery
30 and screw terminal block connectors got more or less torn off, but the rest
31 of the board survived and good data was recovered from the flight.
33 Repaired by Bdale, sent back to Keith on 7 July 2009. Keith reported the
34 baro sensor as flakey, it was replaced in October 2009 prior to
