This is the tutorial for my fully customizable combination lock. This design I used is slightly upgraded from the last design, it uses a smaller RS Nor Latch that it a few ticks faster. This design can be easily expanded to 15 digits, I just used 5 in the video. Overall I feel that this is a very good size for a fully customizable lock, although I haven't seen any other designs. I hope this is easy enough to understand, if not just ask me in the comments.

Thanks for watching.
