I’d like to see a stackable approach and an official TOH Development Kit:
Frames and Other Halves:
- are stackable (in principle)
- pass I3C and power on to the next Other Half
- reuse the normal phone back with its NFC antenna, so NFC remains functional
- can be secured using screws when needed
- have studs to hold the phone battery in place
- have an opening for cameras, wide enough to avoid vignetting with 2x TOH mounted
