The sound frond podium under construction. This is where we put all the interactive components for a trial run at Recompression 2010.

Inside the podium case: top is the theremin with control board face, under it is another black box containing the Arduino Mega, solar charge controller, Rougue Robotics MP3 board, and miscellaneous fuses and power distribution blocks. Also mounted in the exterior are 3 infrared motion sensors and 3 ultrasonic range finder sensors.

Next shelf down are two weatherproof speakers, and on the bottom is a deep cycle battery to hold the charge generated by the solar panels and used to power the system and lasers at night.
