Two MIT students might have a lucrative safe cracking career to fall back on if they don’t land jobs that interest them. Instead of buying off the shelf motion controllers and hacking these together to build a complete system, I opted for an all-in-one controller. I built an Atmel microcontroller based control board to connect Grant’s laptop to the stepper motor, RC servo, optical encoder, limit switches, an optional LCD screen. The control board connects to a laptop via USB and talks to a computer just like a serial port. I wrote the microprocessor firmware in C and used an in-circuit programmer to download code to the chip. There are about two thousand lines of code in the firmware, and that does not include any of the actual dialing algorithms. After two rounds of PCB’s and about a dozen firmware revisions, we had a fully functional dialer.”

Can I borrow it? I have a private vault in my shop that has become a 5500lb paperweight. I left the combination with a friend who saved it in his gun locker. When I finally managed to loose the combo, he had done the same. So, here I am.
I thought of contriving my own safe cracker but I am too old and lazy. I only need to use it once, I promise.

wait, does it have sensors to tell when it’s getting the combination or is it brute force cracker?

well a total guesstimate for how much it would cost to hack this together:
Arduino Microcontroller–$30
Servo–$5
Other stuff for connections etc–$30
so $65 plus however much time you need to figure out the software side of things
