Build Your Own 6-DoF Spatial Stylus for $155

Professional-grade spatial tracking has long been one of the biggest barriers to experimenting with projection-based interfaces. While motion capture systems like OptiTrack can deliver impressive accuracy, they also carry price tags ranging from $5,000 to $15,000, putting them well beyond the reach of many researchers, makers, and university labs. A new open source project from Aalto University aims to change that by providing a replicable six-degree-of-freedom (6-DoF) spatial stylus that costs a fraction of the price of existing commercial systems.

Developed by Krisjanis Rijnieks, the Lighthouse Stylus is designed specifically for projection-based CAD/CAM and human-computer interaction research. The stylus achieves better than 1 mm positional accuracy while remaining inexpensive enough to build in a typical fabrication lab. Rather than requiring specialized motion capture cameras, it leverages Valve's Lighthouse tracking technology through the Tundra Tracker ecosystem.

The project isn't completely open, however....

Claude Opus 5.5 comes to Microsoft Foundry for long-running coding and knowledge work

AI models are increasingly taking on work that extends far beyond a single prompt: building a feature across a codebase, investigating a complex issue, synthesizing hundreds of pages of information, or working through a multi-step business process. As that work gets longer, raw intelligence is only part of what matters.
