2 years ago, to learn redstone better, I created a notebook for myself to record builds and tutorials for understanding.

I dug this up yesterday. To redstone non natives, the note may seem helpful and informative. But digging deeper, my understanding of different contraptions are still limited, many understandings written down are still vague, all I can do is just recite some builds or make some untested ideas that turns out impractical. In the long run, this note cannot help me to have a full understanding and able to alter or customise some contraptions. Nevertheless, the fun of writing this helped me to grow interest in how different things work and enter my first step in redstone
