Camera-Slider

This project is a camera slider, useful to take smooth video shots, long moving timelapses, repeatable movement for special effect shots and much more.

Features :

  • 2 motors for translation and rotation
  • Compatible with phone control and a custom controller
  • Saving points and playing them back
  • Custom speed curves
  • A ton of possible shots : timelapse, special FX overlaying, object tracking.
  • usb-c charging for both, the slider is compatible with any usb-c battery bank (~20W peak)

Workflow :

  • connect
  • Set 2 points or more by hand
  • choose speed curves (or leave the default one)
  • choose the kind of shot wanted
  • start recording
  • press play

Questions

How big is the Keys PCB?

It measures 56 × 44.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Keys use?

4 parts. 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 Keys KiCad files?

From the ceansounet/Camera-slider repository on GitHub, at the commit this page was made from: the board is PCB/CONTROLLER_PCB_REV_A/keys/keys.kicad_pcb and its schematic PCB/CONTROLLER_PCB_REV_A/controller/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keys design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
