Invented brand
The brand
ENTREFER is an invented Neuchâtel instrument maker that builds Hall-effect keyboards: every key is a magnetic position sensor, read eight thousand times a second.
What I made
- A Blender camera that orbits the board as it comes apart — drag to turn it.
- A switch sequence you play with your own keypress.
