I’m developing a compact armband that does more than simply hold a pair of true-wireless earbuds. The unit must: • accept and charge the earbuds inside a dedicated cradle • show remaining battery percentage on the armband itself • provide soft LED accent lighting that doubles as a quick “at-a-glance” charge indicator All power management, enclosure design, and cradle geometry need to be optimised specifically for modern wireless earbuds (no wired option required). I already have rough sketches of the form factor; what I’m missing is a full product-ready package that blends industrial design, electronics, and user-friendly ergonomics. Deliverables I’d like from you: 1. 3D CAD files of the armband body and earbud cradle (STEP preferred) 2. PCB schematic, board layout, and BOM covering the charging circuit, battery gauge, and LED driver 3. Firmware or micro-controller logic to drive the battery monitor and LEDs 4. A short assembly guide and manufacturing notes suitable for rapid prototyping or small-batch production Files created in SolidWorks/Fusion 360 and Altium/KiCad are ideal, but I’m flexible if you have an equivalent professional workflow. Once I approve the design, I’ll move straight into a physical prototype run, so please keep component availability and DFM considerations in mind from the start.

Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience taking compact consumer electronics from early sketches to prototype-ready CAD, PCB, firmware and manufacturing notes, including Li-ion charging, battery gauging, LED indication and small ergonomic enclosures. For your armband, I can turn the rough form factor into a practical design package: the earbud cradle geometry, armband enclosure, charging and power-management PCB, battery percentage/LED logic, BOM with available parts, and assembly notes suitable for a first prototype run. I will keep DFM, component sourcing, heat, comfort, and battery safety in mind from the beginning so the design is not just attractive in CAD but buildable. A few details I would confirm before starting are the target earbud model or size envelope, preferred battery capacity, expected runtime, display type for percentage, and whether you want any sweat/water resistance target. I can also support the prototype bring-up and firmware tuning after the first boards are assembled. Please contact me to discuss details.
