Dry wood is one of the best electrical insulators, behind diamond and air. All of the parts for these cable lifters came from Hobby Lobby: 2" x 3" wood bases, dowel rods, thread spools, and wood glue. Sandpaper and paint are optional. Glue the dowel rods to the bases, with a nice amount of glue forming a ring or collar around the rod at the base. Let dry. Lay the spools on a table, flat end down, spaced evenly apart.
I confess: I am a techie at heart. I've been using a soldering iron since I was a small child, worked in electronics in the military and as a field engineer in industry for many years, and have built and tweaked subs, preamps, speakers, and other components. The first thing I do after a new component is out of the box is to "pop the hood" and visually check it out.
Here, then, are projects that you might find interesting.
