One of my unfinished projects has been to convert a cheap little Harbor Freight LED flashlight into a fixed-frequency strobe light for setting the speed on my Kleinschmidt machines. One of these days, I should finish that. I have a long history of half-finishing project designs and then getting distracted by a new squirrel.

The general idea was to replace the 3-cell AAA holder with a CR123 cell, and sandwich a little PCB between the CR123 and the LED head. The PCB would have a little microcontroller on it which would flash the LED head at the desired frequency. Some 3D-printed or machined parts would keep things from rattling around.
