I dialed

Peter and I made the dial box out of laser-cut particle wood. This box will show the user’s comprehension of a lecture to help the teacher know what to talk about more. I also made the 2nd top for the dial box, this version will have a frosted acrylic segment cut into the top, with LEDs under it. Whenever the dial is turned, that amount of LEDs will show up to indicate where the dial is pointing.
