Their prototype shutter looks 3D printed, which would be a good way to guarantee a lifetime of spare parts availability, aside from perhaps the electronics for actuation. It will be interesting to see if once they have completed the proof-of-concept they will switch over to machined aluminium or injection moulding for the some of the more stressed/precision components in the finished product.
What amused me with the video was what appeared to be the technician cycling through different shutter speeds, which looked to me like simply slowing down the speed at which the shutter blades open and close rather than increasing/decreasing the dwell time between the blades actuating. I wouldn't expect that to be the actual mechanism in any finished product (or even the point of whatever the tech is testing!) but that couldn't be good for even illumination across the frame? Or if the aperture was stopped down would it actually matter once the blades cleared the diameter of the aperture opening?
Even so, advanced tinkering like this is always fun to see, and if the shutter works well as a direct Copal replacement and is affordable it may end up being more popular as a stand-alone unit than the lens itself!
