Electronically controlled shutters are still a going item in optics and laser applications. Uniblitz and Melles Griot make them. They aren't cheap, and they aren't a drop in replacement for Copal shutters of course. For example,

I have to think that with electronics and miniature motors becoming so cheap and fast, someone could design and build an electronically timed leaf shutter that is compact and works off a few volt source for between-the-lens or behind-the-lens use. For example, the SWM/HSM motor technology that goes into autofocus lenses today is much smaller, faster and more powerful than camera AF motors of the 1990s. However, there would have to be a market for tooling up to make it. You can buy motors, but the shutter leaves and bearings need finer tolerances than cottage industry 3d printing (I think - I haven't done any 3d printing).
