Yesterday I got to work with one of the venders to set up the new software for the Dental Clinic on our campus. Part of that process required us to calibrate the digital x-ray machine. Rather then give ourselves a dose of radiation we snapped pictures of a cell phone and my swatch watch. Have a look(click for full size)!
The inside of a cell phone. Taken with a dental cam.
The inside of my watch. Notice the driver motor with a screw gear.
I am hoping I get a chance to go back and set it up next time they get a software upgrade.
