hello empire! i like redstone, and i can build u farming devices, cobble gens, obsidian gens, good (and efficient) doors, and even teach u the basics with classes! we can talk on timing and payment, but just putting this out there.... ~Thetrufflehunter
The problem with buying a specific machine is that if someone knows the basics of redstone, they can make it work by just building it themselves. Classes are tough as well, but they are better imo because you can use demonstrations. The minecraft wiki page on redstone circuits is big and complex, but really helpful.
this may be, but there are noobs out there who do need this stuff. and its fun! way better than farming an npc farm XD
for cobble, i believe theres versions, but not the one i make. dang, should have titled it res utilities...
