The last time I updated on GAGA-1 it was when I cut the hole for the camera. Since then I've had a little time to work on it and things are getting close to completion. There's still a bunch of software to write for the flight computer, but that shouldn't take long. The launch will now be in the early spring when the winds are favourable.
First, here's a nice shot of where I was. It shows the interior of the capsule with the recovery computer mounted in place, a rough location for its battery pack and the camera. The two SMA connectors are for the GPS and the GSM antennas.
Finally, I painted and hot glued polystyrene balls to the ends of the antenna pieces to stop me (or others) getting poked by it. Here's a shot of GAGA-1 on its side with the antenna in place (the pieces are held together by a small round piece of plastic I found in my box of random stuff).
1. Fit the Lassen IQ GPS to the Arduino board
2. Write the flight computer software
3. Connect up the DS1821+ temperature sensors
Then I'll be ready for a full system test.
PS Having got all this stuff done I did a quick weigh in by shoving everything in the box (batteries and as yet unsoldered components). It weighed in at 989g. Pretty close to my original desire for 1kg.
PPS I will publish a schematic of the Arduino board when it's done.
