The Soonpho M7 Pan Tilt Head is a useful photography tool for remotely aiming a decently-sized camera. Only, [Kyle Housley] wanted a little more control than was available out of the box. Hence, he built a custom controller that could deliver just that.

The project is based around an ESP32-S3 paired with an NRF24L01 wireless module. The ESP32-S3 is hooked up to a computer to receive commands over serial on what movements to make. It then transmits over the NRF24L01 to another NRF24L01 module that has been hacked into the original M7’s controller. In doing so, it can command the M7 to move to a given specific pan and tilt position, or to make a smooth motion along a vector. It can also trigger shutter release in the attached camera as needed, to capture whatever is being looked at.

[Kyle] has used this rig to create a motion tracking system for aircraft photography. With a Yolo vision model running on a laptop, the pan-tilt head can be commanded to track aircraft passing by and photograph them when they’re in frame. It’s a pretty slick setup; we’d love to see similar done with the aid of ADS-B data, too—perhaps even with automatic image tagging and upload.
