Using Minecraft's Elytra, I built my base in a big mountain. When you fly in, it activates tripwires that open a 3x5 piston door. Thats my secret enterance.
Then I built a machine that puts my armor on a hook and takes off my elytra. It puts on a beacon when I'm in the building too
Then I have some carrot and potato farms, the potatoes are auto-cooked. I also have:
- Hopper network, auto storing my stuff
- A sorting system for my chests.
- Redstone lamp indicators, telling me how full my system is.
- An item request system
- Auto crafting system
- Auto lighting, using the new observers.
- Auto farms, farming iron and gold and redstone. Its auto smelted and sorted.
Thats it, so far.
OH, and I have a slime block launcher, that is just for fun
