[Brad O'Connor] has completed his motorized projector screen that we mentioned last month while covering his Lumenlab projector build. The screen is driven by a windshield washer motor using the low speed connection. The 126″ screen is supported by a copper pipe and is attached using Velcro. Brad says the wrinkles aren’t visible during playback, but he plans on adding more weight to remove them. He’s also planning on wireless control in the future.
