>>1886697https://www.instructables.com/Carbon-Tape-Heating-Pads/There's the project for the carbon tape heating pad. It takes much longer to document than actually build. End up taking about 100 photos along the way, multiple at each step in case some are out of focus. Then lots of photo editing, cropping, resizing. Ended up taking another 30 photos for the title image, trying different things to cut down on reflections on the plastic (eventually turned off the overhead lights).
