“The gigacopper device to do gigabit Ethernet over phone line is a miracle!”
This is the kind of practical hack that should exist but usually doesn’t. British homes are riddled with phone jacks from decades of landline monopoly, yet running ethernet through old plaster walls is a nightmare. These German adapters repurpose that existing copper at gigabit speeds with sub-millisecond latency. It’s a reminder that sometimes the best infrastructure is the stuff already in the walls, waiting for someone to figure out a better use for it.
