A compilation of most, if not all, mechanics redstone-related as referenced in the "Redstone circuit" page in the Minecraft Wiki. There are labels around each object that are signified by command blocks with light-weighted/gold pressure plates above them. Anything else are side details and should be easy or are unnecessary to identify. 

There is a teleporting system set around the area as well. One is the box (second image) that is located at the beginning of the map and is where you can select where to go. The others are the orange-stained clay blocks with light-weighted/gold pressure plates on top of them. Depending on the direction the clay blocks are facing, they will teleport you to the next section of the circuit.

I'm weird, aren't I?

I made this...a year ago, I think? I had fallen out of the loop with names of redstone terms, and I went to the Minecraft wikipedia page to help me with that. Played around in a generic grass-flat-world, organized it a bit, and eventually decided to do the whole page. How tedious that was, and for no real reason or practical result.

Oh well. Have fun with this then, I suppose. I'll be posting another for-reference-like project a little bit later or simply tomorrow. I made it a while back, but I actually make edits to that one every now and then. I don't want the system to think I'm spamming, after all. See you in a bit.
