Bradley's Build Log

Love me some RS-485. How are you getting wires to it? Do you already have some running to the door? Will they run power as well?

Going to slap in MAX or SP3072E and bobā€™s my uncle! haha. RS485 is still a bit new to me.

The wire is coming off the RJ50 jack going down about 6ft to the door. The RJ50 jack supply +12V, 5V, +/-485 signals. The door has 2 switches, which will tell me if the said door has been opened and if the box has been removed. IR sensors to tell me what state the lock is in to provide feedback to MCU to let me know what position itā€™s in but in the event, if the sensors were to fail then flag us and put the MCU into limp mode so things remain locked. If the lock board failsā€¦wellā€¦time to get the blow torch haha

Iā€™ve been pondering about building my own door lock system 'cause I donā€™t trust any of the commercial onesā€¦ Can you describe your use-case a little and what the mechanical hardware looks like?
