Mounting a GoPro to a quadcopter or even shooting it out of a slingshot may be extreme GoPro uses, but this one may take the cake. “May” being the operative word, since I’m not entirely sure what’s going on. Asian characters, and pictures of multiple circuit boards make for a confusing “read.”
I think the gist of this project is that the person made a custom lens mount, but that’s just conjecture at this point.
I thought readers would at least want to see this contraption. It’s at least worth a look for the entertainment value.
