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 all those suggesting a smartphone... that’s not the base tool so much as the base compute+comms backend. More handle than business-end. Looking for sensor/actuator type suggestions. Or specialist comms /compute like R2D2 socket probe or a lock-pick/code-break thing.
