A computer enthusiast has garnered attention for an intricate PC modification that incorporates a miniature, functional model train running on tracks directly atop the graphics card within a desktop case. The unique creation blends specialized model railroading with high-performance computing hardware.
The mod, developed by Reddit user “Beautiful-Turnip-353,” features a T-gauge train, one of the smallest scales available for hobbyists. This tiny scale was chosen specifically to fit the confined space above the graphics processing unit (GPU).
Unlike a static display, the train actively circulates on its miniature track. An Arduino board, connected via USB, supplies the necessary power and signal to the tracks, enabling the train’s movement.
The creator plans further refinements for the prototype system. Future iterations aim to integrate train speed control directly with the PC’s operations.
One proposed enhancement involves utilizing a motherboard’s PWM fan header. This would allow software, such as FanControl, to regulate the train’s speed. The enthusiast envisions a scenario where the train could accelerate as the GPU heats up, tying the model’s activity to the computer’s performance.
Despite its innovative nature, the project faces limitations. The current prototype’s speed requires further calibration for optimal adjustment.
Space remains a critical constraint; the tight radius of the curves and the overall area preclude the use of any model train scale larger than T-gauge. Thermal and airflow considerations also pose challenges, as the added tracks, components, and moving train could potentially affect ventilation or introduce vibrations within the PC case.
The project was originally reported by Tom’s Hardware last Thursday.
