Turntable To Display Hologram Disk

[Old_Geezer]

Probably a long shot but I'd like to find the item in the title above.

Decades ago, on my trip to the US I saw a street trader flogging both a small turntable with overhead light, and holographic disks. Put the disk on the turntable under the light and it revolves, and the image of whatever is captured on the disk appears above it.

Wanted to get it but being unenthusiastic regarding carting the turntable back home and maybe damaging it, I asked how much for the disk alone; and bought it. I thought it can be hard to create a turntable from a stepper motor and added light. But the disk has laid unused ever since.

Anyone seen this sort of item and know where a turntable can be bought ? Failing that, anyone know where one can download "blueprints" to build one (maybe in a couple more decades time) ?

Cheers.

is it anything to do with this?

No, not really. Probably similar technology. The disk is like a CD in dimensions, and sits flat on the turntable. The figure it encapsulates appears in 3D above it as the light from above shines on the disk. Theoretically I ought to be about to knock a turntable together to display it, but in over 30 years I've not got around to it; so would be interested if they were still sold.

Apparently the disk I have is called 'Lovely Rita" which, IIRC is a decent description. Bought a stepper motor and inclusive driver board, but it looks like I now have to find a processor board to drive the driver board, and find out how to connect it somehow. Anyone any experience with that ?
