Labs and makerspaces
The Humanities Hub at the Leiden University Centre for Digital Humanities has an AI lab, but perhaps even more interesting a small makerspace (3d scanner, 3d printer, camera based scanning).
Digital Art Lab in Zoetermeer has a variety of tools and equipment, open Fridays 13-18.
Space Leiden (hacker/makerspace) (only open on thursday evenings)
