Sun Dawg Exhibit
The SunDawg is a mobile solar energy educational exhibit that evolved over several years in cooperation between CMDITR, the Advance Energy Materials Insititute and the Center for Built Environments. The first iteration was a set of three aluminum frame panels with 2 eye level poster sides measuring 30"x 24". One the panels contains an electronic picture frame. Another panel contains an interactive solar cell displays with flashing LEDs controlled by arduino.
