Sometimes you just wish there was more time ... Tennessee's brainstorm that we launch a SPOT in a weather balloon has taken on a life of its own. Team A51 has gotten into full gear, you can keep up with the very latest here but the basic story is that a bunch of us in the lab have decided to follow in the footsteps of some great experiments in 'edge of space science' ( I just learned that term ) check out some of the links from the google group .. just amazing. Anyhow we are calling our first attempt at this EDGAR-1 , for EDucational Gas-filled Aerial Rotunda, it seems to have caught some peoples imagination with the very latest being an engineer here in the labs who pilots aircraft volunteering with some of his friends, to help us out with an aerial chase vehicle! how cool is that?
The only down side is how much time the project is cutting from some of the other work the team is doing (starting with the solar panel stuff I posted about before ).
This is a shot of the payload, radar reflector and parachute. Lachlan is putting the whole rig together.

Here's a quick snap shot of some of the things that we are attaching to the SPOT, still working through the code but we are using a custom daughter card that Tennessee made to control a camera via some TTL output pins, taking reading from a pressure sensor connected to an SPI ADC, and finally using the UART module on the arm9 to communicate with a Telit GSM/GPS module ( which is a super cool module ), there is also a MB of flash on there where we are recording our sensor readings. ( I apologize for all the acronyms, but thats just how things go sometimes )

I snuck a picture of Tennessee and Lachlan working on getting our GPS and the MicroTrak talking to each other properly, so that we can track our payload using the amateur radio network.

If you just cant wait to take a look at the code you can get it here , in the directory named 'Edgar', but just after the launch we will move it into its own project at java.net called spot-balloon.
