HacDC Spaceblimp 5

Spaceblimp-5 Planned Launch: July 9, 2011

Summary

HacDC Spaceblimp 5 is set up for launch on Saturday morning 10:00 AM.

This time we're going for altitude. By using a larger balloon, hopefully it will burst at a higher altitude, 120k feet predicted.

Come join us for the launch, at ____.

Or follow along at home!

There are two radios on board the blimp that transmit out the GPS data:

• The primary radio is tied to the GPS and transmits out to a network of amateur radio enthusiasts who then pass the location information on to get mapped here: APRS.fi. We also are running some custom software that passes this data on to a Twitter account (once per minute!) which you can follow on your phone: DC Spaceblimp Primary Twitter Feed. (Click the link in the Twitter to pull up a map!)

• The secondary radio is actually a GSM cell phone module, and will broadcast its data when in range of a cell tower. It will be broadcasting both GPS data for tracking, and a lot of the sensor data for science. You can follow that Twitter feed through Society Of Robots Twitter Feed.

Payload

The payload contains a couple cameras:

• a video camera (Canon Zi6)
• a still camera (Canon Powershot A-480) running custom firmware to get better exposures from space

and a lot of instrumentation:

• a geiger counter
• 9 degree-of-freedom IMU (Inertial Measurement Unit on Wikipedia)
• high-speed (50 sample/sec) accelerometer
• internal and external temperature sensors
• humidity sensor
• air pressure sensor
• IR and visible light sensors
• a solar panel, hooked up to measure the voltage
