This is a very old project I had sitting around in my redstone world. Today I decided to take some nice pictures of it, and upload it! It can be locked when either open or closed, and is very compact. It's also very fast, because I used as few repeaters and logic gates as possible. Also, expect something big soon! I'm working on setting up my youtube channel, and as soon as that is done, I'm gonna upload a big project of mine! (Not the one I gave a sneak peek for, but a minigame).
