Using copper and other metal foils works, we used copper on secure microcomputers back in the olden days (early 1980s) designing and building Tempest class secure systems for the military. But even heavy copper shielding is not nearly as effective as the spray applied carbon pigment paints. I...

Did you read the frequency response chart that you linked to? I don't think we care about electrical impedance through the applied material for hum and RFI just how much suppression we can get from the material. Look at how much more effectively the carbon paint suppresses the RF energy from...

I had a look at conductive paints and the test results show that the MG Chemicals carbon based acrylic paint is the best by far. Has anybody tried the carbon paint? I know it is effective on lower frequencies and limits noise from small processors and controller chips but has anybody here tried it?
