In the television series “Star Trek,” the character Spock used a “tricorder” to take measurements after being transported to a planet. A University of Arizona researcher, Dr. Peter Jansen, has developed a working tricorder. His model can measure temperature, humidity, magnetic fields, atmospheric pressure, ambient light levels, distances, and contains a colorimeter, GPS, accelerometer, and gyroscope. It is also open-sourced, with plans available for anyone to build one.
