Built My Own Pro-Level Button Box for Sim Racing

I built a custom sim racing button box inspired by the Porsche 991 Cup car—complete with 16 inputs, 3 rotary encoders, LED-backlit switches, and a clean plug-and-play USB interface. No SimHub Required. No software setup. Just straight performance, designed for serious sim racers who want real-world motorsport functionality at their fingertips. In this video, I’ll walk you through the full build process, wiring with Arduino, and how I made it feel authentic to a real GT cockpit. Whether you race in iRacing, Assetto Corsa, or just love building your own gear, this one’s for you. Key Features: – Porsche 991 Cup-inspired layout – 16 programmable buttons + 3 encoders – Arduino-powered, no SimHub required – LED toggle switches and rotary encoders – Works as a native USB game controller 🔌Join The Channel Membership: Exclusive STL Files    / @thirdwheelexclusive   Support the Channel Shopping through the TWE Store or using our affiliate links not only helps the channel grow but also provides you with exclusive discounts.
