This is how to make the fast Direction Detection contraption. There's dead-spots so if it doesn't hit the on/off, move it up or down. If you build it on the left side, you need to load it with a door. This skeleton shows both left and right loading, you don't need both.

Made this left/right detector on discord together with @5xWhale . We've recently discovered a lot of new techniques to build and optimise contraptions! I will post more examples soon

Global position detector idea. While the POW ensures the Mole can't move off global ground, the winged mole still moves the spring whenever it turns. This allows a simple setup with two Thwomps on either side to simply work as expected - instead of triggering continuously!

Another 2 bit state machine example. The left side always toggles OFF when the stack is DOWN. The right side always toggles ON when the stack is UP. The left Spikeball is pushed outward and the right Spikeball is held down by the stack. The red/blue blocks push the Spikeball back
