Oh, I have four 1 inch round magnets for a dollar, and a pack of 12 for a dollar half inch paper binding clips. I clip the clip on the mirror, squeeze the wires and remove them, stick the mirror and clip on the magnet. My table happens to be a wrought iron outdoor table so they stick, but they are heavy enough to sit on a table. I had to learn to touch the mirror and only move the magnets carefully. I will measure the angles and restrictions for getting this image because it took me a couple of hours to wrap my head around what it was doing. Finally, I have a stack of sticky notes blocking the laser beams from hitting the screen, so the camera is not washed out. The lights are out, except for the computer screens. Looking forward to seeing what I can do with the data stream. Will put a picture and diagram. Will record some data and play a bit. I have other things I am doing, but will try to do more later today or tonight.
