Grating Bling
Description
Wasatch Photonics is a manufacturer of gratings and spectrometers. Gratings are useful optical devices that utilize the princple of diffraction to bend and split light.
Grating Bling is the name for one of Wasatch Photonic's trade fair set ups. Gratings of a variety of sizes are put in front of a display with 4 colors of LED - White, Red, Green, and Blue. The display is animated to fade between just the white LED, and mixing red, green, and blue to produce white. By looking through the gratings, it's possible to tell the difference between the LED white light and the mixed white light. The white LED produces a continuous spectrum, while the mixed white has 3 distinct bands.
I built the display by selecting components, programming the microcontroller, and assembling the parts.
