I wanted to replicate many parts of the Ai pin and did research into laser projectors. It’s probably a MEMs projector. The cyan color they use is custom, at least. Minifying that tech and making it robust enough to be knocked around on a wearable device is pretty challenging and I couldn’t find anything of a similar size off the shelf. They also run pretty hot and apparently the pin has heat issues (and according to folks at CES (?) using the laser a lot makes it over heat.
