Compact PCB Design for Sinus Relief Device

@macroenergy

With over a decade of experience in circuit design and electrical engineering, I bring to the table a keen understanding of micro-sized devices like your custom sinus relief tool. My forte lies in creating compact, portable PCB designs and choosing compatible components. This, combined with my deep knowledge of embedded systems and sensors, makes me an ideal fit for your project. I have an impressive track record working on various implementations of vibration motors and thermistor-based temperature controls; both essential to your apparatus. Furthermore, my familiarity with Li-ion batteries, charging circuits, and battery protection will ensure safe and efficient power management for extended use. Other assets I possess include efficiency in producing production-ready Gerber files and thorough documentation for assembly and testing. Though your timeline may seem short, flexibility has always been key to me managing complex projects like yours. Hence, I am sure we can adhere to your timeline without compromising on quality or performance. Let us discuss how I can bring your vision of compact power-assisted sinus relief to life in quick time! Looking forward to hearing back from you, Metin

Hi there, I’ve read your specification and can deliver a compact, production-ready PCB and firmware package for the pen-shaped sinus relief device (schematic, PCB layout, Gerbers/NC, BOM, PnP, source files, and 3D checks). I’ll design the adaptive vibration and pressure-sensor input path, safe thermistor-based temperature control with limits (35–40 °C), Li-ion charging and protection (space-efficient charger topology), auto-shutdown timer, and manufacturable outputs ready for JLCPCB/PCBWay. I have direct experience with small form-factor PCB layouts, vibration motors, thermistors/temperature control, Li-ion charging circuits (TP4056 and alternatives), pressure sensors, MCU control/firmware, battery safety, and producing fully annotated Gerbers/BOM/Pick-and-Place files — I’ve worked with every component and constraint you listed. I’ll follow safety and thermal best practices for skin-contact devices and can sign an NDA if required. If that sounds good, message me and I’ll share a short project plan, milestones, and a fixed quote so we can start immediately. Best regards, Samuel Tshibangu

I am very interested in your project and confident that my experience in embedded systems, PCB design, and small form-factor electronics makes me a strong fit. I have previously worked on compact medical/wearable devices, vibration/thermal control circuits, and Li-ion battery powered systems, ensuring both safety and manufacturability. Deliverables: Full schematic integrating vibration motor, heating element with thermistor control, Li-ion charging/protection, and microcontroller. Compact PCB layout optimized for pen-sized housing. Gerber, Drill/NC, Pick-and-Place, and complete BOM with available components. Source project files (KiCad/Altium/Eagle/EasyEDA) for future updates. Optional 3D rendering for enclosure fitting. Documentation for assembly, testing, and safety compliance. My focus will be on delivering a production-ready, reliable, and safe PCB that can be directly manufactured via JLCPCB/PCBWay, with adaptive vibration, controlled micro-heat therapy (35–40 °C), and safety features like over-current protection and auto-shutoff timer. I am committed to clear communication, step-by-step updates, and confidentiality (NDA if needed). Timeline can be 2–3 weeks with a flexible budget depending on complexity.

@CHAPAPPA

Hello, Thank you for the detailed specification and device functionalities. Is the device battery powered? It should be based on its use. I'm an IoT and embedded system engineer with strong experience in PCB design for consumer devices. I master Altium Designer and KiCad in my designs. I'm used for many microcontrollers and I can suggest the best one for your project. I can help in developing firmware too in the future or give firmware instructions with a detailed description. I have some of my PCB projects in my profile that you can check out. Feel free to contact me. Best regards,

@amarjitk17

I have strong PCB design experience with medical devices. I designed an ECG monitoring system in DipTrace, created the BOM and Pick-and-Place files, and ensured manufacturability. With this background, I feel confident in helping you design your sinus relief system and contributing to your company’s growth

@hammad4191

Hello, This is exactly the kind of project I take on - compact PCB design with embedded control, battery management, and sensor-driven operation. I’ve worked on small form-factor devices combining vibration, heating, and safety features, so I can handle both the electronics and firmware aspects with attention to reliability and manufacturability. Given the scope - battery + charger circuits, microcontroller logic, MOSFET-driven vibration, heating regulation, and NTC calibration - I estimate about 55 hours of focused work, which would reasonably fit within a 3-week timeline. I’ll provide full design deliverables (schematic, PCB layout, BOM, manufacturing files, and source project files) along with clear documentation so future updates are straightforward. Looking forward to discussing your requirements further and building a production-ready design.
