So for "scanner" I'll share with you what I can do with mine -

on setting '1' I can check the immediate vicinity for aliens, paranormal entities, and other earthly energies.
on setting '2' I can check for weapons of any type from ceramic hand-gun to pulse phaser, but the field is limited to directional detection.
on setting '3' it doesn't do much but input images from physical to digital form to my pc.

So next object - pencil sharpener (uses other than sharpening pencils if possible please).
