Description<\/strong>
\nA quite ambitious project where the main idea is to send a payload up with a latex weather balloon to take pictures on its journey.
\nPreferably there will be a telemetry system that will send the payload’s GPS coordinates as well as altitude, temperature aso. down to ground level.<\/p>\n

I’ve only just started on making a concept circuit, so the project has quite a long way to go.<\/p>\n

 <\/p>\n

Payload<\/strong>
\nThe payload will primarily consist of:<\/p>\n

-Microcontroller <\/strong>Arduino Duemilanove\/UNO
\n-GPS-receiver <\/strong>For now I’m using a GPS-received stripped from an USB-GPS. It works, but I don’t know what its maximum operating altitude is.
\n-Some sort of gyro, sensing the position of the payload <\/strong>At the moment the sensor module from a Wii NunChuck
\n-Radio transmitter <\/strong>At the moment an XBee, but the range is limited too about 100m. Hopefully I can utilize the XBee Pro or something even more powerful
\n-Camera <\/strong>Preferably a Canon camera compatible with the custom firmware CHDK<\/a>. I can then use the Arduino to remotely trigger it through a customized USB-cable.
\n-GMS\/GPRS device <\/strong>If the telemetry gets broken or doesn’t work as it should, I need to be able to find the payload when it comes down to the ground. By sending an SMS with the GPS-coordinates within certain intervals, it should work as a backup ‘telemetry’ system. At the moment I’m looking at the Arduino library SSerial2Mobile<\/a>. If I can get my hands on a Motorola C168, I think it should be a quite straightforward task.
\n-Temperature sensor <\/strong>I just got a couple of LM35 <\/a>sensors the other day, and they should be ok for internal and\/or external temperature measurements. They’re rated for -55C to +150C, so hopefully the range is ok.<\/p>\n
