Bdale and all, What are the four holes on the middle of the TeleMini? They look like they might be for a CMOS level serial header. If so, can they be used to reprogram the TI SOC? If so, is it theoretically possible for me to modify the firmware to accept serial input data and transmit that data to the ground? I am interested in a radio link for my own electronics projects, but the RF part doesn't really interest me. X-Bees and so on do not have the range and very low power requirements that TeleMetrum products do. And since i need deployment control anyway, TeleMini seems like its worth considering. Summer is coming! Cheers, -Bryan

Falls Church High School SLI team successful full scale test launch w/Telemetrum

by Dan Moses (Home)

In case you are interested, the FCHS SLI team I am mentoring flew their test launch with a Telemetrum running the show. You can check out their FRR presentation in their document page: http://www.fallschurchsli.org/documents I was particularly impressed the acceleration and velocity values recorded by the Telemetrum could be used to derive the Cd from the coast-down data. The only fly in the ointment is that the .kml file output from their flight does not work with our version of Google Earth (6.1.0.5001). The Google Earth display of this file literally looks like the flight spanned the globe. Any hints on what went wrong? -Dan
