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
