What would be a good base tool for a sonic screwdriver or tricorder, as a literal high-tech computer-based multi-tool, built around an arduino or RPi?
I mean the way a knife is the base for a Swiss Army knife or pliers for a leatherman?
Actual screwdriver? Thermometer? Tweeter?

For a tricorder sort of deal, an SDR or an oscilloscope, or ideally one of the neat ones (red pitaya?) that have the hertz range/resolution to be both simultaneously
Antenna design could be an issue, though
software defined radio.
can not be missing on any self respecting tricorder!
