(when I used it in the video it was still a WIP)
The lock uses an ATmega328P I had laying around (so of course it's an overkill).
The RFID tags values that are allowed to open the door are stored in an SD card (I was too lazy to use the MCU's EEPROM).
The electromagnetic lock is switched on or off using a TIP142T.
And the RFID reader is an old RDM6300 module I also had laying around.
The micro switch is used to detect if the door is closed or not.
I'm planning to make an inverter so that the door can still be locked in case of power cuts.
The components are currently soldered on a prototype board but I'll etch a PCB soon.
