Laura has opened a new store. She would like to advertise this. The more light and moving elements, the better the advertisement. Can you help her make a fun, eye-catching billboard?

In this workshop, a drawing on plexiglass is animated by using different colors and programming the LED strip in the correct sequence.

  • Total internal reflection of light in transparant materials.
  • Small squares, facets are cut on a diamond.
  • All facets must fit together perfectly.
  • By perfect grinding, 99.9% of the incoming light will reflect.
  • = Optimal brilliance


WHAT DO THE PARTICIPANTS LEARN:

Facts:

- Describe the critical angle and total reflection with concrete examples.
- Describe and illustrate additive and subtractive color mixing.
- Describe the concepts of main colors, mixed colors, complementary colors for additive color mixing.
- Describe the concepts of main colors, mixed colors, complementary colors with subtractive color mixing.
- Explain the perceived color of light and objects using principles of subtrative and additive color mixing.
- Describe the concept of color of an object by indicating which light colors are absorbed by the object and to what extent.
- Describe the concept of color on a website as a combination of the light colors red, green and blue.

Skills:

- Soldering
