Recently expanded my windmill tower. With the building this wide, the windmill shouldn’t actually be turning in real life, but oh well. I spread the mechanical power out to the three machines here; Saw, Mill Stone, and Turntable. The switches on the left side of the screenshot control each one individually and the one on the far wall is the master switch. If all machines are off, so too will the main gear box. If any single or combination of machines are on, then so too will the main gear box. The master switch is a safety precaution for rain, allowing me to disengage the main gear box without worrying about running around and turning off up to three other switches. Eventually I’ll replace it with a detector block.
There’s some red stone circuitry on the roof (it just ANDs all the inputs) but it’s ugly and I don’t feel like showing it. I did learn about sending redstone power vertically through inverters today, though. That’ll come in handy when I get around to making my elevator.
