Catalog2 publishedOne page at a time
How things work, one mechanism at a time.
Interactive 3D models of machines and instruments. Turn the object, take it apart, and follow the part that does the job.
Every Mechanism is a workshop for taking things apart. Each page is one object, modelled in Blender. The parts are named, and the writing stays in plain language: what the piece is, what moves, and what that changes.
You can orbit the model, split it open, and try the motion yourself. New pages are added one at a time. Everything already published stays in the catalog below.
In the catalog now: How a Trombone Works and How a Carburetor Works.
What a page lets you do
-
Turn the model
Drag to orbit it and scroll to look closer. The mesh is the same one built for the page in Blender.
-
Take it apart
Separate the pieces and see which part is which, instead of guessing from a single photograph.
-
Try the motion
Move the slide, the throttle, or whatever actually does the work, then read why that movement matters.
