Launch Parameters
Balloon and Payload
Balloon and Payload
- 36" Qualatex, unstretched
- 23.2 gram payload
- 3.0 grams free lift
- Half-wave antenna.
Heat sealed neck.
Experiments:
- random WSPR channel selection
- reduced weight, keeping free lift the same (3g), what happens to altitude
- box launcher
Weight saving approaches:
- Thin board (0.6)
- Cut off headers
- Thin antenna (magnet wire)

Actuals
Launched from parking lot next to Barnes and Noble
Ripped off bottom antenna
Top antenna was tangled with ribbon
Hit some buildings on the way up

General Thoughts / Observations
Again, stop launching in stupid ways.
Develop a better approach for launching.
