Spacebridge meeting Sep 11th 2011 at Noisebridge


Christopher and Onno

- we need a new balloon source

 - the $150 are probably too small
 - the 100g balloons were free

- we need a better battery

 - battery power split/managed
 - better battery for the arduino/intervalometer
   - intervalometer
 - better battery for the camera
 - power bus?

- we need better launch organisation - better cabling for the video equipment - suggestion (Onno, former discussion with Mark): Build nice acryclic frame to mount everything,

 - power wires etc.

- we need video recording - birthing bag - better video receiver

 - 'ground support equipment' with nice video screen, video recording, video
   streaming

- get legal information/double check on multiple payloads per balloon and

 weight limits

- build a rope-cut device. Avoid running a set of cables to above the

 - parachute. Heat wire around nylon rope?
 - test cutting device in freezer (is completely exposed to ambient
 - temperature!)

- order styrofoam, new, larger - have item tracking list on wiki - cleanup spacebridge wiki pages
