Gunther Cox’s recreation of the Doctor Who movie prop packs an Arduino Pro Mini. If you’re not familiar with the show, the Doctor’s sonic screwdriver is a deus ex machina element that does pretty much everything and moves the plot forward whenever needed. Gunther’s version packs an electromagnetic field meter, voltage detector, dog whistle, brown note generator(!), sound meter, ohm meter, volt meter, and also works as a universal remote, flashlight, and laser pointer.
