Now why is it not working?

… Two days before launch date!



The simplest DIY Geiger radiation detector ever

Completed sensor pack hardware


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…
