In 2013 I bought out 2 Radio Shacks worth of ferrite beads when I was hunting down signal noise in my senior design project (CNC mill rebuild and update.) All else fails, add more beads.

Also, I learned that you can make your own shielded flat cables with aluminum duct tape.

Who knew that they had a really good reason for using 48V signaling in the original machine controls from 1986?
