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
