Made on request of my wife.
It’s a laboratory equipment used to mix, blend, or agitate substances in a tube or vial by shaking them.
Functions:

timer
motor speed control - rpm (quite accurate)
angle adjust by replacing Crankdeg part: 10deg, 15deg, and 20deg
save config: default time and rpm to mcu memory
