Exploring Underwater with a 3D Printed Head Tracking FPV Camera Dome

We all know that FPV is a lot of fun in the air with quadcopters and fixed wings, but what about from underneath a boat looking below the water? And what if you could immerse yourself in that underwater world and control the camera with your head? That’s what I wanted to find out, so I dusted off my big 3D printed catamaran RC boat (link to files below) and set about adding a head tracking, first person view camera system all housed in a waterproof dome with its own dedicated lighting system. I used a combination of 3D printing and acrylic to build the dome housing and LED lights to light things up (link to files below). Everything was waterproofed using a combination of hot glue, silicone sealant and polyester resin. The 3 axis pan and tilt mechanism is a cheap off the shelf unit that uses micro servos that provides about 180 degrees of rotation. An analogue FPV camera is used to provide the live video feed back to goggles and an Insta360 Go 2 provides the HD video recording. These are both mounted o
