Here are some of the balloon components with explanations of their functions.


 

Main payload package containing transmitters and other instruments.

A cheap digital camera was disassembled and used as an inflight camera. Photo is taken every 50 seconds thru a hole in the main payload package.

Mini-transmitter will broadcast GPS coordinates on 144.39 MHz at a power of 300 mW thru a simple dipole antenna.

An even smaller transmitter will send a beacon signal, N5QEM, thru a simple dipole antenna.

GPS receiver antenna is mounted in the lid of the payload package that is made out of styrofoam.

Module will independently record air temperature at regular intervals during the flight.

This one pound rechargeable battery will power the onboard instruments.

Shows the size of the payload relative to a Yaesu FT-60R handie talkie.

Ironing some of the problems out of the payload assembly... a little humor here. Thank you very much.

This is the payload with the tether straps and carabiners for attaching to the harness beneath the parachute.

The payload is attached to this ring, which is attached to the parachute. The rings keeps the parachute shrouds from tangling during freefall.

This is a balloon in a bag, but you probably guessed that already. :-) Along side is the fill tube.

The cannister below the payload is an audible beacon, which activates automatically when the payload hits the ground.

N5QEM, Bill, with the shine, marking the shround lines. N5OTD, Mark, is assisting.
