In this follow-up video, we dive deeper into the world of retro-inspired computing by upgrading our unique Raspberry Pi Zero laptop and adding a custom-built clip-on trackball. If you enjoyed the original build, you're in for a treat as we enhance both the functionality and aesthetics of this compact, command-line interface device.

Our journey begins with a revisit to Fusion 360, where we design a custom enclosure for the trackball, ensuring it seamlessly integrates with the retro aesthetic of our laptop. Using the internals of a '4D mouse,' we craft a bespoke clip-on trackball that complements the vintage-inspired design. You'll watch as the design comes to life through 3D printing, with careful attention to detail and the use of the same Inland beige PLA to maintain that nostalgic computer look.

In addition to the trackball, we perform a general rebuild and upgrade of the laptop, making subtle improvements while retaining the original physical hardware, including the Raspberry Pi Zero 2 W, Adafruit PowerBoost 1000C, and the 3.7V LiPo battery. We’ll walk through the assembly process, showing how the new trackball integrates with the existing setup and discussing the challenges and solutions involved in this upgrade.

As we complete the build, we'll test the new trackball alongside the updated laptop, demonstrating how the enhanced setup performs in a portable, retro computing environment. We'll also take a moment to appreciate the balance of modern functionality and retro charm that this project embodies.

Whether you're passionate about retrocomputing, a Raspberry Pi enthusiast, or simply curious about unique DIY tech projects, this video offers a detailed and engaging look at pushing the boundaries of custom, portable computing. Join me as we take this Raspberry Pi Zero laptop to the next level with a custom clip-on trackball and explore new possibilities in DIY maker technology!
