Build This Inexpensive and Versatile Remote for Your Blackmagic Camera

Professional cinema cameras are — to put it lightly — enormous. There are numerous reasons for that, but technology has come a very long way. Now you can purchase small and relatively inexpensive cinema cameras that actually perform pretty well. You won’t be shooting the next Star Wars movie with one, but you can capture footage that is decent enough to work in indie films. The Blackmagic Design Pocket Cinema Camera 4K (BMPCC4k) is one option, and Jeppo7745 has a tutorial that will show you how to make your own wireless remote for it.

Unlike most other DSLR cameras, just about every function of the BMPCC4k can be controlled via Bluetooth. That’s likely a result of Blackmagic making it a priority for this camera to be useful in situations where a typical cinema camera would be unwieldy. This particular remote is designed to control the aperture, focus, and recording. Theoretically, you could modify it to control anything else you might need. Best of all, you can build this remote for about $20, making it the most affordable accessory you’ll likely own and use with a Blackmagic camera.

To make this remote, you’ll only need an ESP32 development board, a potentiometer, and a button. A 3D printer is also ideal for making the enclosure. Jeppo775 used a TTOGO Micro32 ESP32 development board because it’s very small, but you can use a larger one if you’re okay with the remote not being as compact. All you’ll need to do is connect the button and potentiometer, and the provided code will take care of the rest. The simplicity of this design is thanks to Blackmagic making the camera easy to work with, so you might as well take advantage of it!
