By type of mechanism
A gear printed one evening in 2025
Adrien is an industrial designer. One evening he printed a gear and spun it with a fingertip; through 2025, prototypes piled up on his desk. The shop opened in 2026.
Every model goes through a dozen prototypes, often more, before it is printed in a batch. In the workshop, the parts are then detached, sorted by step and counted before they leave France.
The journal
One article a month on the history and mechanics of a model in the catalogue, written by Adrien.
Thermodynamics,
The radial engine, cylinders in a star around a single crankshaft
Cylinders in a star, a master rod, an odd number of cylinders: the engine that crossed the Atlantic and carried the first airliners.

Breguet's tourbillon (1801) and gravity in a pocket watch
In 1801, Breguet set the whole heart of a watch spinning on itself to cancel out gravity. The history and mechanics of the king of complications.

Why a spinning gyroscope does not fall over
Spun up to speed, a disc refuses to tip and swings sideways when you push it. From Foucault's experiment to the navigation of aircraft and satellites.
