Ever have trouble connecting a new computer or DVD player to a projector? I know you have because it happens to me all the time. Epson’s PowerLite Pilot Connection and Control Box is a big step forward for classrooms because it can simplify and centralize where all those cables go. It works with the company’s short throw projectors and lets the teacher manage audio and video connections. It has ports for HDMI, S-Video and a pair of VGA connectors as well as inputs for audio. It even has an optional wireless microphone and can connect to external speakers, turning it into a PA system for the class. It’ll go on sale in June, with the connection box costing $250, with the speakers and microphone adding $150 and $450.
