Durable DIY Bluetooth/aux audio kit with visible components and clear educational value Key benefits Teaches practical electronics and audio assembly: assemble a complete, working audio device to develop handson soldering and wiring skills. Immediate, usable result: after assembly the kit functions as a playable speaker, compatible with phones via Bluetooth (MHM18BT) or through the audio jack. See, learn, troubleshoot: the included transparent housing exposes the internal layout so you can observe circuit behavior and diagnose issues without disassembly. Reliable components for consistent performance: the kit includes the MHM18BT audio module, the 8002 power chip, a 3W speaker, and matching peripheral components engineered for durability and lasting use. What's included and how it performs MHM18BT audio module: provides wireless playback capability and easy pairing with mobile devices. 8002 power chip and peripheral components: manage power delivery and signal flow for stable operation. 3W speaker: delivers clear, improved sound, particularly when mounted in the supplied housing. Transparent case: protects the circuit while allowing a full view of the internal structure; design reduces handling wear and simplifies inspection. Why customers need this kit Handson education: converts theoretical knowledge into practical competency—ideal for learning circuit connections, power management, and audio signal routing. Readytouse audio solution: builds into a functional speaker that can play music or audio from a phone, laptop, or other source. Durable and longlasting: constructed from materials chosen for robustness so the assembled unit can withstand regular use and repeated demonstrations. Compatibility and technical notes Playback options: works with mobile phones and other audio sources via the MHM18BT Bluetooth module or a wired audio jack connection. Power and audio management: includes the 8002 power chip and all required peripheral components for stable performance. Acoustic performance: 3W speaker provides improved audio when properly housed; volume and fidelity are typical for a small, selfcontained DIY speaker. Typical use scenarios Classroom and teacher training: handson lab sessions for technology basics and competency training where instructors need a simple, demonstrable audio project. Hobbyist and beginner projects: weekend build for electronics enthusiasts, makers, or beginners wanting a clear, functional result and an easy path to learning soldering and circuits. Practical demonstrations and troubleshooting practice: use the transparent case to teach circuit tracing, component identification, and fault diagnosis during workshops or maker events. What to expect after assembly A durable, functional audio unit that pairs with Bluetooth devices or accepts wired audio input. A practical learning tool that improves assembly skills, circuit understanding, and troubleshooting ability. Visible internals for ongoing study and demonstration without frequent disassembly. Notes Kit requires assembly; basic soldering and safe electronics handling are recommended. All components listed (MHM18BT, 8002 power chip, 3W speaker, peripheral parts, and transparent housing) are included in the kit.
