BalloonSat Mini Servo Version 1.0

The low cost BalloonSat Mini Servo is a near space datalogger designed to collect data from one sensor while it operates a camera and servo. The servo can be used to operate experiments, like a Petri dish sampler. It's easy to assemble and permits some basic biological experiments in near space. Its programmability permits students to vary the data collect rate, determine when and how the servo operates, and change the rate at which photograhes are taken. It's Sensor Port makes it easy to swap out sensors and refly the flight computer on another misison.

Features of the BalloonSat Mini Servo v1.0

  1. Small, only 74 grams and it measures 1.4 inches by 2.5 inches
  2. Operates from 4 "AAA" cells (lithium batteries recommended because of the cold)
  3. One A to D channel provides 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 channel is 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
