I build a Zwift connected fan that blows more wind as you go faster, to simulate real world conditions in my pain cave. If anyone is interested, i will make a manual on how to build your own. Also here is a video of the fan in use (turned backwards to show the moving parts). https://photos.app.goo.gl/DX1hgXk7IufHDHkj2
update: Here's the manual. https://www.instructables.com/id/Internet-Connected-Fan-for-Use-With-Zwift Hope you manage to rebuild it. If you have any questions or suggestions, let me know!
