I'm very fortunate to have access at work to an X-Ray machine. These are a few images I've been lucky enough to take so far..
A machine-wound 540 size motor. I'd love to look at a hand-wound someday.
A bunch of mechanical watch pics. My favorite is the Accutron, if you don't know this watch or it's space history, it's worth looking up.
This image shows the unwound spring, and the "roll of music".
Inside of a knife. Notice the carbide bearing pressed into the back as a glass breaker.
I found this poor little guy dead behind some equipment at work. Notice the big teeth, these are the ones that keep growing. I also understand now, the reason mice can fit into such small places. Their ribs can "fold" back, making them very small.
Notice the motor windings and the ball-bearings. This is a titanium-geared servo. This would be hard to get a good picture if the gears were plastic. X-Ray Machines like changes in density.
See where spark erosion cutting of the metal was not completed.
Great view of a diode. Perhaps to keep the solar separate from the battery.
X-Ray shows a thin piece of metal between the set screws to align the jaws for correct measurement tip to back.
The switches are half cut vias on the PCB.
The bottom left of the image shows fly weights that control the speed of the pulse.
This is a very nice 3/8" ratchet. Great design. Notice that it only needs one spring for the selector detent, and the ratchet mechanism.
Check out the "Full Metal Jacket" (a copper jacket covering the lead core) of the projectile.
Notice the gradient of the blade where it gets thinner towards the edge.
Notices the dense lead that has splattered in the suppressor, and notice the double wound recoil spring.
AS style autosport connector, 6061Al enclosure, 4-40 screws, and a teensy microcontroller.
