DIY Enthusiast Transforms TicWatch into Innovative Gear Knob Display

A remarkable project has emerged from the intersection of automotive passion and DIY ingenuity, as Desmontei has successfully converted an old TicWatch Pro 3 smartwatch into a functional gear knob display. This innovative creation not only shows the car’s active gear but also allows users to control Spotify playback with swipe gestures.

Desmontei's project highlights the potential of repurposing old technology. By merging the smartwatch's display and motherboard with a custom 3D-printed housing, he has crafted a device that sits directly on the gear lever. The smartwatch, running on Wear OS, uses a specially developed app to interpret data from the car's accelerometer and gyroscope, reporting the gear position based on the detected angle.

The initial iterations of the gear display faced challenges—particularly in accurately reporting gear data while driving on inclines—but Desmontei refined the algorithm. This adjustment improved the accuracy of the gear readings and showcased the iterative nature of DIY projects. Plans for a second version of the device are already underway, with potential enhancements based on community feedback. Desmontei is considering using stronger printing materials and adding additional sensors to further boost accuracy.

The dual functionality of the gear knob extends beyond mere display. Users can swipe through tracks or pause their Spotify playlists directly from the knob, adding an unexpected layer of convenience to the driving experience. While some may question the practicality of looking at the gear lever while driving, the project effectively demonstrates the broader capabilities of integrated technology in vehicles.

This venture serves as a testament to the creativity within the DIY community, illustrating how 3D printing and coding can breathe new life into outdated gadgets. The concept of vibe coding, which simplifies app development for unconventional uses, is crucial in making such projects feasible. As Desmontei prepares for future iterations, the project stands as an inspiring example for tech enthusiasts and car lovers alike, pushing the boundaries of what can be achieved through innovative thinking and hands-on crafting.
