Description
In this design, a 3D-printed base distributes compressed air evenly to support a floating styrofoam ball, while two sensors measure the ball’s rotation speed on 2 axes. It is typically used with virtual reality setups for mouse behavior (Harvey et al. 2009). This open-source project is modified from a design by the Technocenter, Radboud University in collaboration with the Battaglia lab.
The original design was adapted to
- Accommodate the Logitech G502 mouse model (earlier model was discontinued)
- Distance control – the sensor can be moved closer or away from the styrofoam ball, simply by adding washers between sensor box wall and base.
- Easy access – The sensor box can be easily open/closed (it attaches with magnets), facilitating cleaning. All sensor components can be removed in that way, giving access to the screws that enable distance control.
- Easy anchoring on optic tables with 4 feet compatible with M6 screws.
This project requires 3D-printed parts (FDM), 2 Logitech G502 mice, a valve and a few screws. See the Assembly Instructions document for a detailed bill of materials and step-by-step instructions.
