I have been playing minecraft for a while now but I have never really messed around with using redstone circuits. After the update a few days ago I made a minecart track with some booster rails that would take me from one of my mines all the way up the mountain that my house is situated on and was quite proud of my little contraption. And after seeing that article about the guy who made a computer in minecraft I was thoroughly intrigued with the possibilities of redstone circuits . So escapist I was wondering what have you made with the use of redstone circuits?
