SOhio 2017-1 Downward Camera

The SOhio 2017-1 mission included a downward facing camera.  This was a Canon A495, running a CHDK intervalometer program.  Pictures were taken at roughly 20 second intervals.  About 380 in-flight pictures were taken. Additional information on the flight is contained in a previous post, Picam in the Sky. However, some relevant flight information is: Launch … Continue reading SOhio 2017-1 Downward Camera

Picam in the Sky – SOHIO 2017-1

Last Saturday, Aug 12, 2017, we flew a Raspberry Pi carried by a 800gr weather balloon.  The payload reached 105.5 kft, and more importantly, was recovered.  This is a preliminary report to show the results of the attached  PiCam camera.  The Pi ran throughout the entire flight, as shown by the file creation times.  The … Continue reading Picam in the Sky – SOHIO 2017-1

A Raspberry Pi WiFi Access Point for HiBal Missions

A Raspberry Pi WiFi Access Point for HiBal Missions Abstract: During Pre-flight checkout, and post-flight data dumps, I’d like a balloon payload flight computer to function as a stand alone wireless access point. I show how to setup a Raspberry Pi as a stand alone wireless access point, and include shell scrips to switch between … Continue reading A Raspberry Pi WiFi Access Point for HiBal Missions

Starting Sensors on the Raspberry Pi

One concern about using a Raspberry Pi for high altitude balloon projects, is the ability to reboot the computer and restart data collection.  I've had power interrupted during flight missions, sometimes due to loose wires but often due to batteries dropping in voltage due to the cold.  Things can restart at higher altitudes as payloads … Continue reading Starting Sensors on the Raspberry Pi

Talking to the Raspberry Pi A+

I am contemplating using a Raspberry Pi A+ as a data logger for a balloon flight this summer.  I am intrigued with its potential as a low power computer which, with a wifi adaptor, can serve data files and images.  This may be especially useful if/when the payload gets stuck in a tree, or lost … Continue reading Talking to the Raspberry Pi A+
