Seems i forgot to upload the finished demonstration unit.
Apologies for the kiddos in the background.
This shows off the door simulator in read mode, then i use the admin card to switch the mode to Door mode. I show off an unauthorized key and the no-entry display. then i use an authorized key and shows it triggers the relay to power the mag plunger.
Admin cards can be enrolled in the web interface or hard coded before compiling. I am also making it so the first time running the code it will prompt to enroll the admin card to the reader.
Also i added the Demonstration unit’s STL’s to the git. This one seemed to gain the most popularity. Lots of changes occured that deviated from the original plan to make it so similar to Red Team Alliances Building in a Box. Originally they had multiple cards that changed the modes. I did that, and found it incredible cumbersome. I had to either hard code 4 cards or use 4 magic cards and clone my admin cards to it. Seemed like a shit end user experience. So i made one admin card that just cycled the other modes and it made the 4 card system obsolete.
Also with the ESP32 you can unenroll admin cards and authorized cards. The web interface giving access to that and allowing you to plug into Home Assistant i think is the best option between the Arduino version and the ESP32 option. but for cost and ease of parts the Arduino version works great.
I used this device as my primary testing rig at Defcon33 and it worked flawlessly. highly reccomend it to anyone that wants something fun to play with.
