Strange but true: although I can't claim to have been on the research team that invented the data diode, I *was* on the research team that invented the first cheap optical data diode. We packaged it up into an Altoids tin. Total materials cost was under $100, and most of that was spent on the custom PCB. > Data diodes are unhackable because it relies on the law of physics... Oh, quite the contrary. It just forces the attacker to get clever.
