TL;DR: The first finished version of the Project Resonator guide is officially live! New dedicated documentation website, comprehensive wiki entries for PCB design, shell design, and manufacturing. Administrative sections (How to Contribute, Licensing, FAQ) now complete. Future plans include IEC711 coupler testing, custom crossover simulator, and TWS designs.
TL;DR: Switched to the latest VituixCAD (old file is archived under /legacy). If you've modified the old crossover, it won't open in the new version --- you'll need to manually copy things over. Driver setup is now CI22955 + BK23824 + 2× SWFK 31736, bringing costs down to ~$250. Dropped the PCB in favor of direct soldering since it makes shell fitting easier. Removed the outdated SMD list. First physical prototype is underway thanks to some preliminary funding.
TL;DR: Project is still moving forward. The PCB has been redesigned to fit the shell properly, which improves component placement and reduces crosstalk/noise. I've also started developing EarCanvas, a cross-platform open-source node-based tuning app. On top of that, I'm working with my college on potential funding to build the first working prototype. The reason for the long silence is that college and extra summer courses took most of my time, but I've been making steady progress in the background.
