Interesting project but I wonder if this is mostly academic. Wheatstone bridges are very sensitive to tampering. While the reflectometry is pretty cool I wonder if for practical purposes the extra sensitivity is needed for physical intrusion detection. While 10€ may not be much for securing a payment terminal a wheatstone bridge is a lot cheaper.
