So i made a world only for the different redstone gates. they should all be in there, but if i'm missing any you can throw a comment and i'll do my best to update it asap :)
throw a diamond if you like it!
Also, i love making minor redstone contraptions similar to a BUD-switch i also made you can check it out at my profile, but i'm having a hard time getting the ideas, so throw a comment if you got something you need help with or you want me to make and i'll do my best!

PS. i included a day/night sensor in the map that you can feel free to use for whatever purpose! it's great for lighting up a survival town at night
The day/night sensor isn't mine, i found it on youtube by xDowsey
