Tiny Model Train

Summary

The Tiny Model Train is a project that involves creating a miniature model train designed to fit inside a Christmas ornament. This project features a controller that the host built and highlights various design challenges, such as track assembly and electrical failures related to the wireless LED system. The episode titled "I Built A Tiny Model Train and it Nearly Broke My Brain" outlines the journey of creating this model, emphasizing the complications faced during its development.

Design

The goal of the Tiny Model Train project was to create a compact model train that could operate within the confines of a Christmas ornament. However, this endeavor was constrained by the size and complexity of the components required to make the motor and PCB compact enough to fit. The host made decisions regarding the shape and size of the design, ultimately opting for solutions that would allow for both mechanical movement and the necessary wiring for the LED system. As explained in the episode, "I thought would be impossibly small to print. Turns out that's true only half the time," which reflects the trials faced in achieving the desired design.

What Failed

Throughout the development process, several issues surfaced that hindered the project's progress. A major challenge was observed with the track assembly, which behaved unexpectedly, as the host noted, "...the tracks... acted like a coil naturally because they are." This presented problems with electrical functionality. Additionally, the initial design experienced failures with the overall wireless system, prompting the host to eventually shift towards a more mechanical movement solution.
