The Conserve the Sound Project has recordings of the sounds produced while interacting with a large variety of old devices. For example, typing on a typewriter, inserting an audio cassette, opening the lid of a laptop. I’m glad that people have thought to pay attention to, and capture these otherwise ephemeral sounds. Aside from the pleasure of hearing them, I think it adds an important dimension to understanding their context in use when we no longer use them. This may be my favourite site now.
