A stepper motor. You can see that there's a small disc with a black spot on it stuck to the side of the motor shaft. It's a magnet. The shiny thing with the threaded barrel (clipped to a handy reel of full-fat leaded solder) is a Hall Effect sensor which issues an electrical pulse every time the magnet passes it. The tachometer module displays the number of pulses per minute.

Ok so from the second pic I assume the vertical shaft rotates about its vertical axis and that's what you're measuring.

Should I be worried?

Eta., just read this on Wiki.

Is this the automation of your cat repelling water projector?:becool:

Life's been so mundane here in Suffolk that the most interesting thing I have to report is that there was a queue for the CoOp this morning, but not for Tesco. However, there was no queue at the CoOp's checkouts (no self service) while there was at Tesco (both the manned & self service ones).

29 Hours until the alarms go off for the first early shift where I have to be in the office for some time.
