[MOC] Timer Gadget

[TechnicBrickPower]

Hi Everyone. Here I show a build I did a few days ago. It's an unconventional Lego Technic MOC timer gadget. It's based on 4 pins holding back a liftarm that stops the timer. Each pin is motor driven by a different gearing ratio such that the liftarm can only move once all pins align. This only happens when the number of turns of the main axle equals the LCM (lowest common multiple) of the pin gearing ratios. At that point the timer is turned off by a lever controlling a remote controlled unit. Unfortunately it didn't work completely as expected but that's what happens sometimes.
