BalloonSat Mini Version 4.0

The low cost BalloonSat Mini is the next step up from a datalogger-based BalloonSat. The BalloonSat Mini is an easy to assemble project that allows BalloonSat workshops to incorporate soldering and BASIC programming into their activities. The single unit flight computer collects data from 2 sensors while operating a camera. Its program permits students to vary the data collect rate during the mission, change which sensors are recorded, and change the rate at which photograhes are taken.

Features of the BalloonSat Mini v4.0

  1. Small, only 65 grams and it measures 1.4 inches by 2.5 inches
  2. Operates from a single nine-volt battery
  3. Two A to D channels that provide power to experiments and are capable of digitizing at either eight or ten bits of resolution
  4. Camera cable that can be plugged into any camera with a simple shutter switch
  5. I/O channels are not limited to analog voltages, they can also operate and collect digital data from experiments like a Gieger counter
  6. Optional use Commit Pin prevents the flight computer from collecting data until Commit Pin is pulled
  7. Easy to program in BASIC
