After assembling a computer, I have decided to set up a complex security system in case I were to find an SMP server with the Computer Mod. Of course, it won't stop the fiends who force their way in, but if you're like me, you're going to want to leave no trace of stealing things except for the lack of stolen goods. I tend to come back for more, often.
Anyway, like the image says, the Redstonecycle Gate is time-set and keyed. If the time is out of the range and it's not open to the public, I have to have a specific diskette (labelled "Cardkey") to open the door just for ten seconds. In that time, I have to insert the diskette, take it out, and get inside. Managed to successfully rig a 2x3 piston door's circuit, but I lack two more slimeballs for sticky pistons. If I wasn't a little more humble, I'd say I was an evil genius.
Now that's settled, I set off for slimeballs. Dusk is approaching, so I can't take any chances waiting it out. Even if that means flying off a cliff. Geronimo!
Managed to make it to dawn. There's a castle in the background. If being evil and a genius is correct, the drill is to kill everyone and loot everything in it. I hope there's at least two slimeballs in there.
