I needed a motor to turn a small version of Jerry Andrus' Tri-zonal Space Warper. This version is just a bit larger than a 33 RPM record and I wanted it to spin while lying flat on a table. After trying out a few different motors, I ended up using an old floppy disk drive. Many of these drives are being tossed into the trash where they contribute to the problem of disposal.
