My two Zero W servers.

One picoreplayer w/ LMS for music to chromecast. The other runs MyMediaAlexa which can stream my audiobooks to Echo Auto by voice command.

The cable box they're sitting on is unplugged, never used.

Paperweights... Mostly.

But when I feel like fiddling with them, my current main project is a handheld Pi3A+

Using Pi to capture global external shutter videos with Raspberry v1 camera.
The Pi records the video of airgun pellet in flight, as well as triggers the diy highspeed flash with 3kHz/9kHz PWM of 8.33µs duration flashes.
Pi is hidden by the pehllet catcher, on the right side of the photo.

With post processing this is 9000fps animation of airgun pellet in flight, played at 3fps, 3000× slower than real:

As Raspberry "Pyro", ignites an electric match and record 665fps highspeed video of that (played at 25fps, 26.6 times slower than real):

Some MIT students used global external shutter capturing with Raspberry v1 camera to capture rifle bullet just after passing through an apple. That was done numerous times before. What they made special is that they did capture the global shutter image with 16(!) PIs with cameras at the same point in time from different angles. More details in "Ultra high-speed imaging, capturing matrix style bullet time." thread, and on the github repo they pointed to:
https://www.raspberrypi.org/forums/view ... 3&t=240442

Their setup:

One of the result "Matrix" style animations created from the 16 cameras:
