@yaroslavmark

Hi, I am an embedded hardware and product design engineer with 10+ years of experience developing rechargeable LED products and compact consumer electronics. I have completed 80+ PCB designs and multiple injection-molded products, reducing BOM costs by up to 30% and successfully taking concepts from sketch to production. Based on your sketches, I understand the goal is a compact cylindrical keychain light with a translucent body, bright red illumination, rechargeable battery, and USB-C charging integrated into the base. Approach ✅ I will optimize the enclosure for a compact, pocket-friendly design with a translucent light-diffusing body and integrated keychain mount. ✅ I will design the PCB with red LEDs, Li-ion charging, battery protection, USB-C interface, and efficient power management. ✅ I will deliver STEP files, manufacturing drawings, PCB files, and a production-ready BOM for supplier quotation. Questions ✅ What is the target brightness level and preferred illumination pattern (full-body glow or directional beam)? ✅ Do you prefer USB-C charging exclusively, or would magnetic charging/contact pads also be acceptable for improved sealing and durability? ✅ What runtime target would you like beyond the minimum requirement, and do you have a preferred battery size or capacity range? Best, Yaroslav

⭐⭐⭐⭐⭐ Hello, This is exactly the type of compact consumer-electronics product I enjoy developing. I understand the goal is not just creating a key-chain light, but delivering a production-ready design that balances size, durability, manufacturability, battery life, and tooling requirements within a very aggressive timeline. I can help finalize both the electronics and mechanical design, ensuring the device remains under the 30 mm diameter and 10 mm thickness targets while achieving the required runtime and maintaining a clean, pocket-friendly appearance. My approach: • Optimize enclosure geometry for injection molding and assembly • Select a compact Li-ion/LiPo cell and efficient LED driver • Design a minimal PCB with charging, protection, and power management • Recess or flush-mount the switch and charging port to prevent accidental activation • Prepare manufacturing-ready STEP files, drawings, BOM, and assembly documentation Deliverables • Industrial design refinement and enclosure CAD • PCB schematic and layout • STEP files and tooling-ready mechanical drawings • Manufacturing BOM with globally available components A few questions: • Do you already have a preferred battery chemistry and capacity target? • Is water resistance a requirement? • Do you prefer USB-C unless space becomes critical, or should both options be evaluated? I am comfortable working within a 7–10 day schedule and maintaining fast communication throughout the project.
