Shaunville Model Train Set
Summary
The Shaunville Model Train Set is an extremely tiny model train project designed to fit inside a Christmas ornament case, created by Sean Hodgins in the episode "I Built A Tiny Model Train and it Nearly Broke My Brain". The project features an innovative PCB-based flat stepper motor design where electromagnetic coils are embedded directly into the circuit board traces, eliminating the need for traditional motor components. The name "Shaunville" is a satirical play on Sean's name, presented through a darkly comedic framing device at the beginning and end of the episode as a fictional product designed for "keeping captured Shauns busy." The system is modular, allowing users to design custom track layouts using pre-defined curve and straight pieces in Keycad. While technically ambitious, the initial prototypes suffered from serious issues including improper magnet centering, excessive track heating (consuming 10 watts of power), and minimal movement success.
The project is sponsored by PCBWay, who manufactured the custom circuit boards, and the design files are being prepared for release across multiple platforms including GitHub, MakerWorld, Instructables, and Fusion360. The satirical framing creates a meta-narrative about repetitive systems and containment, with the tagline "Get your very own Shawnville model train set because a busy Shawn is a manageable Shawn" tying into The Philosophical Commentary on Loops and Systems that runs throughout the episode.
What Was Said
Sean Hodgins presented the Shaunville Model Train Set with both genuine technical enthusiasm and self-aware dark humor. The episode opened with a mock advertisement introducing it as "The only ornamentsized transportation solution designed to keep your captured Shaun's busy," immediately establishing the project's satirical dimension.
The core innovation—the PCB-based motor design—was highlighted as a breakthrough concept. Sean questioned, "What if you could make the entire PCB and train a motor together?" This approach eliminates traditional motor components by embedding electromagnetic coils directly into the circuit board traces, creating a flat stepper motor system. The technical execution, however, fell short of the concept's promise. Sean acknowledged that the initial prototypes had serious problems: the magnets weren't properly centered, the track consumed excessive power (10 watts), and the train achieved minimal successful movement.
Despite the technical struggles, Sean emphasized the project's accessibility and customization potential. He explained that the modular system allows users to design their own track layouts using pre-defined pieces in Keycad, and noted that "You can even order this exact project directly from my PCB way profile" through PCBWay's services. The files were promised for release across multiple platforms to encourage community experimentation.
The episode's philosophical dimension emerged through the recurring satirical framing. The closing line—"Get your very own Shawnville model train set because a busy Shawn is a manageable Shawn"—connected the specific project to broader themes about people being stuck in repetitive loops and systems. This meta-commentary transformed what could have been a straightforward maker project into a reflection on distraction, containment, and the cycles people create for themselves.
History
I Built A Tiny Model Train and it Nearly Broke My Brain
The Shaunville Model Train Set was the central focus of this episode, serving as both the technical project and the vehicle for the episode's satirical philosophical commentary. The episode began with a mock advertisement introducing the train set as a solution for keeping "captured Shauns" busy, immediately establishing the darkly comedic tone that would frame the entire project.
Sean Hodgins explained the core technical innovation: creating a flat stepper motor by embedding electromagnetic coils directly into PCB traces, eliminating the need for traditional motor components. This approach allowed the train to be small enough to fit inside a Christmas ornament case while maintaining the functional characteristics of a model train system. The design was modular, enabling users to create custom track layouts using pre-defined curve and straight pieces in Keycad.
The manufacturing partnership with PCBWay was prominently featured, with Sean noting that viewers could order the exact project directly from his PCBWay profile. The collaboration allowed for the production of the specialized circuit boards required for the motor system, though the sponsor relationship also added time pressure to the project's completion.
However, the technical execution revealed significant challenges. The initial prototypes suffered from multiple issues: improper magnet centering caused alignment problems, the track consumed an excessive 10 watts of power (causing heating issues), and the train achieved only minimal successful movement. These problems highlighted the gap between the elegant theoretical concept and the messy reality of physical implementation.
The episode concluded by returning to the satirical framing device, with the tagline "Get your very own Shawnville model train set because a busy Shawn is a manageable Shawn" reinforcing the connection to The Philosophical Commentary on Loops and Systems. This closing tied the specific technical struggles of the model train to broader themes about repetitive systems, distraction, and the loops people create for themselves—transforming a maker project into a meditation on containment and purpose.
