[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Something of a repost, but I'd love to hear if anyone has any experience with.... An ULTRASONIC slide projector controller system from Leica in the late 50's...I have found 2 complete sets in my families attic, new in box with a typed note from Leitz NY on their operation.... Anyone ever seen or used these things? The technology is acually pretty intresting. They used ultrasound produced by hand bulbs to control Pradovit projectors....And must be the earliest example of a remote projector. If anyone knows more I'll be thrilled to hear it....
