An innovative DIY project has emerged in which a creative individual transformed a discarded Duracell battery casing into a functioning Bluetooth speaker. Over the course of two weeks, they meticulously hollowed out the battery, successfully creating sound holes and assembling a complete speaker system inside. Surprisingly, the end result delivers high-quality audio, showcasing the maker’s engineering skills and patience throughout the complex process.
The project began with the builder’s commitment to safely discharge the battery, using a toy car motor and some makeshift materials to construct a fan that took three days to remove the remaining charge. The disassembly proved challenging as they utilized an assortment of drill bits and even a rotary tool to extract the battery’s interior, all while taking precautions to avoid hazards. With a mix of power tools and unexpected items like a popsicle stick, the dissection of the battery was filled with moments of both tension and creativity.
After clearing out the old components, they faced the task of creating sound holes. Initially, their first attempt resulted in poorly aligned holes, prompting a shift to a more precise solution. By designing a custom drill template via 3D printing, the builder achieved perfectly aligned openings, showcasing a high level of engineering finesse.
The final assembly included a compact Bluetooth circuit, speaker, mini battery, and various LED indicators, despite the tiny size making the electronics work notably intricate. With careful planning, even using a Photoshop template as a drilling guide for ports and buttons, they ensured every component was cleverly integrated.
Incredibly, after meticulous work with UV-curing glue and a custom speaker sleeve, the compact device was revealed to not only fit in the palm of one’s hand but also deliver surprisingly good sound quality. This project stands as a testament to both ingenuity and patience, highlighting the maker’s dedication to crafting something functional from an unconventional starting point.
