>Look, I'm saying all these papers are weekend Hackaday projects. I'd challenge any hackaday member to create one of these from scratch in a weekend. I've done quite a few over the years for fun, and most involve a significant amount more work than simply saying "measure EM, done!" Some of these do take significant effort to get working, especially if you have a simple understanding of physics, electronics, noise, or measurement. No comments on all your claims on how simple you think defense is? I'm guessing that if you really think one simply says "Faraday cage!" and all EM is solved, or one says "Sound proofing!" and all vibration is blocked, then you also may not understand the value in having the detailed nuances of each of these things worked out. So this stuff seems useless to you. There are plenty of groups getting paid to do stuff that seems trivial to people that honestly don't understand the nuances. And in this space the nuances make a big difference. And, as others pointed out - this is useful to plenty of people as a starting point for stuff they want to do. Knowing that 1980's CRT emanations were leaking does not give someone new to the field the ability to read RAM noise.
