RPI Pico Video Turntable Mk1. Vidio on this project is available at https://youtube.com/@drjonea.
Still images are boring and when they are PCB or breadboard sometimes dificult to understand from one angle. This project is a controlled turntable for small scale video work on my projects.
Features
Lighting Uses a strip of WS2812B LEDs to illuminate the photo area. Controlled in terms of Hue, Saturation and Value.
Calibration Self calibrating turn table driven by a 28BYJ-48 stepper motor
Menu Simple menu displayed on a OLED display and controled through a Rotary Encoder.
Sequence Switch 1 moves the turntable to start possition by shortest route and then moves to the end possition in the direction and speed set in the configuration. Good for setup and repeat takes of the same shot
Stop Switch 2 stops the turntable.
Continuous Rotation Switch 3 provides continuous rotation and the currently configured speed. Short press is clockwise, long press is counterclockwise.
Reset Switch 4 resets the turntable
Pico Reset Switch 5 is the Pico Reset.
Schematic and PCB
KiCad files have been included in the Schematic folder.
PDF version of the schematic is also included.
Gerb files are included in the PCB folder
3D Models
OpenSCAD project is in the folder 3DModels. You will need two supporting libraries.

Questions
How big is the TurntableMk1 PCB?
It measures 134 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TurntableMk1 use?
31 parts, built around the 74LS00SC and ULN2003. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TurntableMk1 KiCad files?
From the jondurrant/RPIPicoVideoTurntableMk1 repository on GitHub, at the commit this page was made from: the board is Schematic/TurntableMk1/TurntableMk1.kicad_pcb and its schematic Schematic/TurntableMk1/TurntableMk1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TurntableMk1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
