Whether you’re selling a product or just showing off your latest project, a photo turntable makes video shots a lot easier. 360° turntables allow the viewer to see every side of the object being photographed, while the camera stays locked down. Motorized turntables are available as commercial products costing anywhere from $30 to $150 or so. Rather than shell out cash, [NotionSunday] decided to create his own turntable using a few parts he had on hand and 3D printing everything else.
The motor for the turntable came from the eject mechanism of an old DVD-ROM drive. An Arduino Pro Mini controls the motor’s speed using an MX1508 H-bridge chip. Power comes from an 18650 Li-Ion battery. The whole assembly spins on the head assembly from a VCR.
Before you jump in on the comments, yes, VCR heads have motors. However, they’re typically brushless motors rated for 1,800 RPM. Running a motor like that at low-speed would mean rewinding the coils. In this case, using a DC motor and gear drive was the easier option.
[NotionSunday] 3D printed the turntable base and mount. The mount uses a magnet arrangement that makes it easy to switch between freewheeling or belt driven operation. The turntable itself is posterboard, with 3D printed edges.
