Progress… at last

Seems like everything is slowly coming together for our first flight, due in 3 weeks!

The LiPo battery of the sensor pack seems to be perfect – lasts for 9 hours in the freezer.  Temperature in the freezer settled at -26 deg C, which, for testing purposes, I am quite happy with.

The parachute is being contstructed this week and the release mechanism was completed by Christo,  Willie built and programmed the release computer,  and I am doing some last minute changes.

Gert spent time building a VHF & UHF antenna with good success.  I am still thinking about my sensor pack UHF antenna, but it will definitely be a simple design.

So now I have to write a few more lines of code…
