Summary

Our current access control system was not all that flexible, and we want to switch to a new system.

Architecture

TODO

Door scanner

We have an Asia-Teco scanner speaks the wiegand protocol (details can be found here: https://a.aliexpress.com/_EJOtZhl). It has the following pinout on the cable:

VCC (+12V)	Red
GND	Black
D0/RX/4R+	Green
D1/TX/4R-	White
LED	Blue
BEEP	Yellow
WG26/WG34	Gray

An arduino combined with a stepup converter is used to translate the wiegand protocol to a text-based format which is exposed over usb-serial. The code for this can be found here: https://github.com/NURDspace/spacenanny-wiegand-arduino. This is linked together according to the following schematic, using a long piece of cat5 as the cable:

This arduino is connected using USB to spacenanny, and we run the tag scanner software there (https://gitea.vm.nurd.space/NURDspace/tag-scanner).
