Mechanical User

Its a block that right clicks things in every way imaginable except for sneak right clicking for some dumb reason. Its made with a dropper, a lever and a resonating redstone crystal.

The block responds to redstone, in either running while powered, running when unpowered, and doing a single action per pulse, or ignoring redstone outright.

Can be upgraded with speed modules.

Despite showing a gridpower tooltip when moused over, it does not require any gridpower to run.
