You can make a isolated OR gate which I will explain if I make a second tutorial which will cover clocks and pulse limmiters too.

Looking at the pictures more closely, Minecraft obviously supports implicit OR gates. That is, violating the rule “never ever connect two outputs”.

So what you have actually done is to build an AND gate out of 3 NOT gates and an OR gate.

You can use the NOT gate to make it a NAND gate if you wish!

Wait a second. A NOT gate has exactly one input and one output. A NAND gate has two inputs. There is absolutely no way to build a NAND gate out of any number of NOT gates.

That’s why the basic building block is NAND and not NOT.

I don’t know Minecraft, so I cannot tell whether your terminology is wrong or whether those redstones are NANDs (or NORs).

PS: And I am not sure if the blogs without downvotes and without other mechanics to catch elementary flows in articles is a good idea.
