Planned devices for the XO.

Devices will be connected to special unit powered by Atmel programmable CPU.

Here are some ideas for possible devices:

  • Thermometer
  • Voltmeter, ampermeter, ohmmeter
  • Oscilloscope
  • Photodiode
  • PH meter
    See also the Digital Signal Processing page for work being done in India
