BalloonSat is a high-altitude university weather
balloon project intended to lead to a student-designed satellite.
I will be flying some HF CW beacons on upcoming
BalloonSat and Space Hardware Club flights at UAH. These beacons
will use a homebrewed MSP430 controller and a transmitter either homebrewed
or kit-built. Desired output power is 100-500 mW, though I may
experiment with less.
I also participate in the
chase and recovery of BalloonSat flights, including two flights in November
In the spring of 2006, I participated in
a senior design project at the University of Alabama in Huntsville to
develop a telemetry module for transmitting several channels of data over
packet radio, thus allowing data recovery in the event of payload loss.
Group members were myself, Jonathan Berry (KF4MME), and Jeb Orr
(KI4ROW as of 10/06), all graduates of UAH's Computer Engineering program.
