Look, it is impossible to explain the configurations of redstone that people like SethBling and FVDisco use just in one comment. Their maps consists of many different clocks, filters and command lines. I suggest you start by watching some YouTube videos, and learning some basic stuff, and then progress on to more complex stuff. I suggest you watch these videos:

Hope I could help!

Look, redstone can be easy or complicated. On a scale from one to ten in redstone. I'm about 7-6. You start small and grow. i used to be terrible at redstone, but with more practice, i became really good. Just start small. Make your own machine or look at a tutorial. Then work up. Use this strategy and you will be great at redstone, like me!

If you think about this logically, it is quite easy, you have the main components such as the memory and there are many birds eye view pictures of calculators etc.
all you need to do is basically copy the picture and learn as you go that's how i learned

Well, I was kind of thinking like being able to make those huge redstone projects. Like CakeBoss, Calculator, in-game computer, just how is it done?

What area of redstone do you want o learn more about mate? Comparators, Gates etc

Anyone posting anything will still help

Redstone can be annoying but fun at the same time! It is very hard to explain like this. If you look at my profile you can see some of the minigames I created. If you want in-depth tutorials, you can PM me! I am always happy to help out!

You sir have incouraged me to start a new youtube series! Block exploration! and i will be sure to start with redstone!

If you look up Redstone on Minecraft Wiki, you will find out a LOT of cool stuff!
