A human friendly way to think of the logic gates
A more human friendly way to think of the gates function is to imagine that every gate asks the input(s) a specific question based on how the gates are built, the resulting answer is the output and is always a yes/no (on/off) answer. Here are some examples:

(feel free to improve/extend the list, or use it in the article if it's good enough, or use it as you see fit) --Sebbes333 01:50, 13 November 2012 (UTC)
 * I like this. I could see this in the introduction as sort of an alternate TOC. But I would put the question first, with the logic gate as the answer:
 * {| class="wikitable"

! Question ! Answered By
 * Is the input off?
 * NOT Gate
 * Are both inputs on?
 * AND Gate
 * Is either input off?
 * NAND Gate
 * Is either input on?
 * OR Gate
 * Are both inputs off?
 * NOR Gate
 * Are both inputs different?
 * XOR Gate
 * Are both inputs equal?
 * XNOR Gate

 * I have been thinking about what kind of questions eg. a RSNOR latch and other circuits asks, but as of now I don't know.
 * Anny suggestions?
 * --Sebbes333 16:07, 13 November 2012 (UTC)
 * An RS NOR Latch asks "Has input S turned on more recently than input R?". A T Flip-Flop asks "Has input T turned on an odd number of times?". --Munin295 20:29, 13 November 2012 (UTC)
 * Nothing to contribute just now, but I wanted to say that I like this approach! Now I'm wondering about D latches and D flip-flops.... --Mental Mouse 22:31, 13 November 2012 (UTC)


 * I'm not sure yet, but you can read this and maybe have a suggestion? Redstone Circuits/Latches --Sebbes333 19:59, 18 November 2012 (UTC)

Input redstone / tables
I would argue that the input redstone of XOR designs C, E and J shouldn't be counted (reducing the redstone count of them to 12, 10, and 7 respectively) as it isn't counted for the other designs. There are probably other cases in the rest of the gates, but I wasn't looking at those very closely. Though, on design J the necessity of those blocks of redstone can vary depending on how power is being routed in from previous gates.

I also made this table for resource cost, but I'm not certain if it would be useful enough to add to the article.

Total costs of each design, not counting regular structure blocks:

Munin's new schematics
For general information: I'm currently converting this page to the new SchematicGrid templates, working at User:Mental_Mouse/Sandbox/Logic Circuits. --Mental Mouse 21:02, 4 April 2013 (UTC)


 * Needs to have a legend like the old page had. Not everyone will understand that the green wool is input, and pink is output.--Skarrd 13:54, 20 May 2013 (UTC)


 * The redstone style guide recommends that the Schematic help template be added to the caption of the first schematic in an article, and to others if helpful. This adds a link to the Help:Schematic page.
