This is a 4 bit user friendly combination lock. It functions with a 10 button keypad with 1-5 entries in order to open the door depending on the combination saved into memory.

Schematic has been uploaded, be sure to read below or watch the YouTube video to learn how to set up after pasting it (World edit doesn't like extended pistons sosome assembly required) also note that the schematic is just the core components and not the full project as it is so far.

Setup

Step1- replace brick half slabs with redstone wire by hand
Step2- replace brick full blocks with redstone torches by hand
Step3- replace obsidian with Iron blocks with world edit
Step4- hit the clear button in the programming room and the safe reset in the keypad room to set the sequencers to their default states


List of Features *Crossed out features are not included in the core redstone schematic*
  • comprised of mostly near instant logic ware speed is needed or ideal
  • instant bus for the input commands (again ware speed is needed or ideal)
  • 10 button keypad with digits ranging from 0-9
  • the length of the combination can range from 1-5
  • use of same digit multiple times in a combination eg. 25252 or even 99999
  • over all total combinations of different viable button presses that can open the door add up to 111,110 (10^5 + 10^4 + 10^3 + 10^2 + 10) (to also clarify combinations like 264 and 7 are also possible)
  • key entry display to mimic the dots shown on many password fields on log in screens
  • failed attempt counter, after 3 failed attempts the keypad is locked down preventing its use.
  • Enter button once you believe you have entered the correct combination
  • Safe Reset button or "Backspace" for use if you know you didn't enter the correct combination.
  • User friendly programming interface, you don't need to know redstone to program this lock.
  • A set of 5 seven segment displays to display the current programmed combination


I know this may seam rather large compared to other combination locks that are really small and can hold more possible combinations, but I am choosing to sacrifice compactness for user friendliness and speed.

Diamond if you like what you see.

Additional Notes

Some screen shots currently up may or may not be part of the the final product as I quite often modify things to make them more organized or more efficient... or completely derp and have to rebuild something.

I don't have access to the world that contains this lock as the owner of the server it was on could not keep paying for hosting. I might get the world eventually as the owner has it but as I see it I have been delayed on working on it for to long and new Ideas on improved designs have come to me. So I will leave the core redstone as the finished product and move on to a newer design; anyone interested should look forward to an improved version to this.

5 digits... is from 00000 to 99999...

ya, that's if you choose to do a combo with length 5. You also need to consider the combinations from 0000 to 9999 and 000 to 999 and 00 to 99 and 0 to 9 which are all distinct combinations.

HA! you planned yours! I just sorta went gung-ho on mine, turned out pretty good imo, but i'm trying to find a way to cramp it all into a small space and still have full functionality
