do you think you are that crazy to built it ?
or are you a normal person mmmmhhhhhh
well if i look at other stuff from you maybe you can do it

@lima X it's possible but itll' be pretty big, this could be a great example to use the 32 byte ram i made tho

well how about a lock that uses an keyboard (qwerty + Numpad) with all keys that an real keyboard uses
with a username and password
also that you could make more then 2 diffrent users (different outputs)
and that you can add a username and password by pressing the same butten as the login it self uses ....

well i think this goes a "Bit" too far

@OttoNL xD this one has 16^32 possibilities :p (only using the right keypad)

For decades nuke launch codes were 0000-0000 in many places in Europe. This is waaaaay more secure xD
