I built a screen that tracks your face and keeps itself pointed at you. It’s mounted on a 2-axis pan-tilt mechanism and uses a camera to detect your face, so the viewing angle stays optimal automatically. You can also reposition it with simple hand gestures.
The build is based on a Waveshare 360° pan-tilt camera module and a Raspberry Pi. The whole thing is mounted to a small projector mount and paired with a 9.7" portable monitor and an IKEA FREKVENS speaker. I ended up flipping the pan-tilt module upside down and designing a custom mounting plate to make everything stable.
For the structure I experimented with a few approaches. The current version uses a laser-cut 4 mm aluminum backing plate which PCBWay generously provided for this project, It's sturdier than the PETG-CF printed version I tried earlier. The covers and some optional parts are 3D printed in aluminium, and the design ended up with a bit of an industrial aesthetic with some Y2K mixed in.
The system works best in decent lighting right now, but the camera can easily be upgraded for better range or low-light performance.
I’ve uploaded the code, 3D models, and laser-cut files, so it should be fairly easy to reproduce if anyone wants to try building one.

Honestly i haven't found a great usecase for it so far though, I mostly use it while I work out to watch movies or listen to music when I tinker with stuff. I thought about creating a kind of digital assistant but not sure, maybe you guys have an idea.
