Reduction attack vs. combobreaker

[jackattack21]

Not totally tracking the connection between this and the reduction attack. Not seeing anything in the duino code about finding resistance on the dial and identifying pins.

Is this a brute force attack of all combinations, just excluding combos that are geometrically impossible based on the tolerances of the locking mechanisms?

How many total possible combinations are tried?

Do you know anyone whose expanded on this and has servos and analog feedbacks doing the full reduction attack?

I know this GitHub is now quite old, but it seems like some folks are currently working on creating their own device. I am currently doing this, so maybe there are folks wanting/willing to collaborate.

I too have been pouring over the code from this GitHub. I only see the brute force attack in the code and a little working towards the reduction attack. I watched Samy's videos (good stuff there) and have been able to break several locks using the technique shown. So today I wrote code to figure out the possible codes from hardcoded numbers of the two lock position numbers, the resistive number, and the wider gap from the two 3rd combo numbers. So this basically does what Samy's website does.

My current thinking and insights: What I am now working on is how to find given numbers listed above. At this point I am not convinced that the device as constructed from this thread is able to find any of the numbers. I also noted that the code in the combobreaker.ino file is attempting to determine the 2 lock numbers between 0 and 10. It does not involve the encoder which would be required to find these two numbers. Also, can this device sense the resistive number using the stepper motor and the encoder?

Can anyone tell me if they have discovered how to find the input numbers, or even if it is not possible to do so with this device.

I have also modified the project to include a LCD screen in the hopes of displaying the found combo numbers. My stl files have been created to include a LCD and a power switch and button to start the cracking routines. If I successfully create the ComboCracker then I will post my code and stl files.

Thanks for any thoughts on all this.
