A 360-Degree Solder-Joint Inspection Device Built with a Rotating Microscope Mirror
bbScope adds a rotating side-view attachment to a digital microscope, allowing inspection of solder joints from all around without moving the object. Creator RealCorebb uses a mirror, prism and concave lens to redirect light into the microscope. Magnets hold the rotating attachment in place.

The object stays still while the viewpoint goes around it.
