Discussed on HN
Engineering becomes clearer when you can see a mechanism, a test or a build. This collection covers manufacturing, transport, construction and projects made by individual builders. It is for people interested in how a design works in practice, including the constraints and failures that a finished product can hide.
Indie Picks is organized from video metadata and uploader descriptions; it is not a full-video editorial review. HN Library retains community discussions. Sources and data notes
