  1. Team PCGMarch Program Review Primary Faculty Advisor: Dr. Nuxoll Secondary Faculty Advisor: Dr. Crenshaw Industry Advisor: Andy McConnell Client: Dr. Kevin Cantrell Garrett Gustafson (Spring Team Lead) Benjamin Co (Fall Team Lead) Wendelin MuellerJulia Weimar-East Project LightBox

  2. Background • Combines the utility of an x-ray viewing light box with the ability to change colors • Assists in Dr. Cantrell’s research regarding color balancing GUI => Microcontroller => LEDs

  3. Methods

  4. Methods • Researched optics • Color mixing • Diffusion • Created small-scale LED grid prototypes • Held many light mixing tests • Various LED configurations • Multiple colors • Software models hardware • Proof of concept programs

  5. Architecture • 2 main components µC GUI LEDs

  6. Architecture – Hardware (Circuitry) • Digital System • We used an Arduino microcontroller that we programmed to accept integers from the GUI representing different duty cycles • 15 output pins on the Arduino were used to illuminate 5 tri-colored LEDs

  7. Architecture – Hardware (Circuitry) • Pin Connections

  8. Architecture – Hardware (Physical) • Physical LightBox • Trapezoidal shape - built with angled walls in order to allow the box to be positioned differently based on how it is being used • Diffuser plate on top to mix the light illuminating from within • Circuitry is installed at the bottom (Arduino at based with the LED grid on top)

  9. Architecture – Hardware (Physical)

  10. Architecture – Software (LightBox GUI) • Programmed in the Python programming language • Allows the user to manipulate the intensity of each of the LEDs within the LightBox • Sends signals in the form of 8 bit integers to the microcontroller

  11. Architecture – Software (LightBox GUI)

  12. Demonstration Enjoy!

  13. Issues • No major issues • A few minor ones… • Time Management • Circuit (Sockets) • Confusing Arduino documentation

  14. Conclusion • Our development process went smoothly throughout the entire year • Hardware Requirements • Complete! • Software Requirements • Complete! • GUI => Microcontroller => LEDs • The Light Box is able to produce a wide variety of colors • Our client, Dr. Cantrell, is very happy with the final product

  15. Any Questions?
