The components of CNNSP’s Main Payload

 

 

 

The camera is a relatively inexpensive 4 megapixel digital from Concorde.

Buy it, bring it home, make sure it works, THEN void the warranty…

 

 

Some groups make their own payload containers, from Styrofoam, foam core, modeling plywood, etc.  I opted for the NSTAR method of the insulated lunch cooler.  With outside temperatures dropping to –70 degrees F.  You need to keep the electronics warm enough to function.

This is a VERY basic design.  A transceiver, microprocessor, power supply, TinyTrak3 module, and a HOBO data logger (not pictured) for collecting data.  The processor is in charge of taking pictures, and potentially a cut down circuit in the event the balloon needs to be cut away.  I’ve have many ideas for improvements and additions for the next design, I just need the time to be able to work on it.

 

 

The Garmin GPS18 receiver supplies the data that is transmitted to the ground stations for real time position tracking.

The camera needed to be electrically shielded to avoid interference with the Garmin GPS18, one of those things you learn from others experiences.  In this case I used aluminum foil, Gorilla Glue, and Styrofoam.

 

 

 

In order to make a SOFT landing… 

I ordered the parachute already made, some groups sew their own.

The spreader ring at the base of the parachute shroud, helps keep things from twisting and tangling.

 

 

 

The finished product ready for another sub-orbital journey.
