A Reddit user has shared his open-source project named Retro Ruler, which is actually a fun project. This can be used to play games in your classes when it gets boring. With its form factor as a Ruler, it’s easy to carry and amazing to play games. This innovative device runs the retro-go firmware, enabling users to play classic games on a functional measuring instrument.
The Retro Ruler is powered by an ESP32 microcontroller, making it a compact and versatile gadget. It features a 1.69-inch IPS display that provides a clear and vibrant gaming experience. The device runs on a 230 mAh battery, offering around two hours of playtime per charge. The ruler itself maintains its primary function as a measuring tool, making it a unique blend of utility and entertainment.
Development is ongoing, with plans to upgrade the hardware to the ESP32-S3 for improved performance. The design includes resin-printed shells and custom buttons, enhancing usability.
The project files, including PCB designs and firmware, are available in its GitHub repository for those interested in modifications or building their own version.
