Liquor Cabinet with SAFE "CRACKING" ROBOT!

  • I made a liquor cabinet out of an old safe. I used an Arduino and a stepper motor to "crack" the safe combination using a keypad rather than turning the dial by hand. Cheers!

              You mentioned you would share how you used other arduino project parts to meet these requirements... Can you link to that?

                Switch out the easy driver for a tmc 2208 or 2130. You can make it nearly silent. The 2208 is easier to use. Another option is the 2100

                    Super cool project. For your next project, it'd be cool if you set Alexa or Google to open the safe for you like you did with the voice controlled dust collection and recording setup.

                          There’s no point in changing the code. You showed us the combo on the dial

                            People, when a word is in quotes, it means 'not really'. "Cracking" means it isn't really cracking the safe. Very cool project.

                                That is thinking outside of the safe.

                                    Would be neat to reprogram it to sequentially try every possible combination until it comes upon the correct one, then see how long it takes to open.

                                      I thought about it. The only hurdle would be finding a way to see if the combination is correct. It would need to turn the knob open and get feedback whether or not it could turn all the way.

                                          Ok, I was expecting some "cracking". This feels like you just took an old safe and made it digital. I mean you can buy a digital safe that same size from Harbor Freight (when its on sale) for the about the same price as what you paid for all your materials. Granted it won't have that geeky cool factor but still. I mean considering all the effort you put into this and the amount of space on the back of the door it seems it would have been cooler to make it more integrated.

                                            cracking a safe with steppers isn't allowed on youtube. It's too effective and achievable. Safe manufacturers are in panic mode and need to introce a time-out like atms and passwords. 1oo failed attempts and come back in an hour would suffice.


                                            This video is a work around to demonstrating how it could be done. Even if it would take a months, it is still profitable.

                                            It actually made it to the new shop! That project is actually important that I finish because it’s one that I gave up on for no particular reason. I’ve quit projects before when they weren’t going like I hoped, but that one was going great and I just never finished it.

                                            That really is impressive....I could feel your success! Unfortunately, I never got into Arduino. I grew up “Mac” and it seemed Arduino was more for PC peeps! But I have to say the freedom to create almost ANYTHING sounds exciting! Thanks for the inspiration!! Lauri
