The hardware project is still ongoing, and below is the current state:

Protoboard Tests

Perfboard Prototype

Turnstile component installation

[WIP]

PCB Manufacturing

The PCB was not yet completely assembled.

Central Module component installation

Requires the PCB to be fully done.

Wiring

All necessary wiring has already been arranged.

Hardware-related tests

Partially done in each component and in the protoboard, but doing them in the final state is still necessary.
