Hi, My name is Karl Semich and I have a desire to make available to everyone highly secure shielded rooms / SCIFs, for privacy and security in this modern age. I was wondering if anybody else was pursuing this, or if anybody knew of anybody pursuing this, that I might stay in contact with them or support them. Or even if anybody had some experience with this concept, and might mentor me, it would be incredible. I don't have any formal training and have developed some cognitive issues, resulting in slow progress, but this is all I am spending my free time on. I do not work a job, being supported for now by a trust. I'm currently residing in Green Bank, WV, where emissions are regulated for a radio observatory. I am trying to develop some relatively simple software using the rtl-sdr to measure the power of a noise source independent of background traffic, so as to quickly and repeatedly measure shielding effectiveness. I then plan to try to measure a variety of setups ranging from homemade aluminum foil & iron paint to soldered copper and welded or bolted stainless steel, to identify ways for everyday people to cheaply create shielded environments that are actually effective. I would like to find a way people can use off-the-shelf supplies to make environments that are isolated from DC to light, if desired. If anybody else is working on something like this, I would love to support you in any way available. I can donate money, I can get drinks and run errands, I can read books and pursue a degree if needed, I can mode hardware around and even develop and debug software. Please let me know, Karl
