Hi there, I’ve reviewed your AI Necklace concept and the provided Gerber files and blueprint. I can tighten the PCB for rugged, heavy-duty use and verify parts availability on JLCPCB, ensuring the design remains manufacturable at scale. I’ll align the board layout with your app integration needs and provide a clear bill of materials so everything is order-ready. For firmware, I’ll reuse/open-source components and deliver a compact, robust stack that communicates cleanly with your app team in India. I’ll document interfaces and provide a test plan that your developers can use alongside the firmware. What is the target timeline for the first batch and preferred communication channel? Best regards, Marko Aleksic

AI jewelry hardware succeeds when the PCB is manufacturable, power-safe, and parts-available before firmware integration starts. Well, what I can do for you as an electronics engineer is review your existing PCB and Gerbers, improve the layout for reliability and JLCPCB assembly, check your blueprint in detail, and prepare a clean production-ready revision that your app team can build around. In fact, I have designed a security camera system schematic and also a high power 10000 watt dimmer including its schematic and circuit design, so I am comfortable reviewing and strengthening real hardware designs and preparing them for manufacturing. 1. No, I have not experience ordering from JLCPCB. 2. None. 3. I have not done tech jewelry specifically yet, but I have done compact electronics designs and PCB/schematic work including security camera system schematic design and 8 bit SAR Logic Design on Candence so I can handle the PCB review and ruggedization part well. 4. Yes, I can support firmware programming, especially for integration-oriented embedded work with clear communication interfaces for app teams. 5. No, AI gives very bogus and straight forward programming structures which do not work always. A human touch and focus is always necessary. 6. For programming of any sort, I always do it on my own. AI is okay for taking some concept and ideas.
