This gadget was bought by Mike Molnar at last year's Kutztown radio meet. The device in front is a selsyn motor, which could be used to synchronize this machine to a viewer. Cliff Benham has speculated that it may be something similar to this flying spot scanner. It was on display at the 2014 Convention. At the Convention, there was much speculation on how it worked. The box with the chimney on top contains a 650 watt bulb and a condensing lens. Behind it is a cooling fan. The motor is not a selsyn, but a standard 3450 rpm motor. There is a magnetic sensor on the front of the wheel. Here is how it probably worked: In front of the disk a 35mm slide was placed. Behind the slide was a TV camera. Field rate was derived from the magnetic sensor on the wheel. This would create a field sequential color output from the camera. It could have used the CBS standard (405 lines) or 525 lines. An alternate idea is that a lens was in front of the wheel, which projected light on a subject to be televised. The camera was aimed at the subject. We hope that someone attempts to get this device working and finds out how well it works. One issue issue is the camera. Vidicon cameras have substantial lag, so they might not be suitable for this application.
