i would be interested to see the internals of the keypad and how the lock communicates with it
I'm more concerned about such thing, that this keypad lack such quite basic feature like.... displaying those digits 0..9 at random order in 3 x 3 matrix, make this display touchable. than if somone tried record owner hitting those 6 numbers using thermal imagining or classic video cam with huge zoom to remeber position where someone hits this keypad, than whatever they do, if next time those 10 digirs 0..9 will be displayed at another random order (TRNG can be used for this, no need to use PRNG on MCU), than position where you press those numbers is worth nothing, since it changes all the time someone attempts to enter this pin code

I wonder, why they didn't made this this way? Even on many web sites this is preffered method to avoid mouse logging or keyboard dumping to takee control over someones account?

Yeah, I don't like this safe lock doesn't have such random numbers placement, but probably it is too cheap or are there as everywhere patene issues which limits manufacturers flexibility who do not want pay too much for patents, so end users gets not the best possible solutions, but something between and still DIY solution can be in many cases better

Anyway, this hack with driling safe side and using thin USB microscope video to try put this bloody connector inside again was really very creative

I need to dig at home througth 0.250m -0.500m concrete wall to see closed space in home under stairs and probably this this USB microscope is must to have in my toolbox, especially it can be perfect for my pick & place & reflow PCB machine too, so considering buying something like this below (without useless tripod) but quite cheap, so I think I'll give it a chance-thigs like this can save a lot of frustration one day and... feel like Hollywood epic win compilation star
