Button Score Counter Design

@markoa7

As an experienced and proficient electrical engineer, I have the ideal skillset to turn your prototype into a functional, low-cost, and scalable product. I specialize in PCB design, embedded software development, and RF circuitry, all of which are key components for your wearable button unit and communication with the speaker unit. I have an impressive record in hardware design, including creating power supply circuits (both DC-DC and AC-DC), multilayer designs for embedded systems and efficient LED driver circuits which align perfectly with your project goals. The comprehensive knowledge I have in these communications protocols (UART SPI etc.) will ensure that the button's score updates are performed accurately and consistently - vital for an audibly accurate end-product. Most crucially, code ownership transfers to you upon full completion of the project meaning you maintain all the rights of the completed work - a fair agreement for utmost satisfaction. Let's partner together to actualize your unique sport device; press the button; score

Hi, This is a good fit for my experience. I’ve worked on compact embedded systems, BLE-based devices, and battery-powered hardware designed for real-world use and future production. For your system, I would approach it as: • Wearable unit: Low-power BLE SoC (e.g., ESP32-C3/nRF52), efficient Li-Po charging, simple LED driver, and robust button handling • Speaker unit: BLE receiver + audio playback module with stable power design for outdoor use • Focus on reliable communication (20–30m), low power consumption, and cost-optimized components What I’ll deliver: • Full schematic (both units) • Cost-optimized BOM (production-aware) • PCB layout (prototype + manufacturable) • Power + charging design • Engineering notes for build and scaling Tool: KiCad (fully editable files) This will give you a solid, low-cost prototype that can scale toward production.

Hi, find my TOP NOTCH similar work on the BLE enabled Sports Wearable Project. The project involved wearable electronics with wireless communication. Before moving forward, please confirm: Do you prefer the BLE module to be based on Nordic or ESP32 for cost and availability? Tools I Use • KiCad / Altium Designer • Arduino IDE / PlatformIO • EasyEDA I am ready to deliver a fully functional prototype system where pressing the wearable button updates the score and the speaker announces it audibly. The focus will be on reliability, simplicity, and cost efficiency. The documentation will be aligned with IPC and IEC standards. Best regards, Abubakar Muhammad

I have made schematics and designed/layed out PCBs on several ESP32 specific boards and some slightly more advanced processors, I would lobe to help bring these schematics to life! As both a Python software engineer and an experienced PCB designer, I bring a unique blend of skills to the table that is perfectly aligned with the needs of your project. With 13+ years of experience developing production tools and working on multiple fast-paced projects, I have learned to think on my feet and deliver efficient, high-quality solutions efficiently. Moreover, my experience in creating 3D models, textures, shaders, lighting shots, rendering using Maya and Photoshop is an added advantage; as it reflects my ability to think creatively and translate complex concepts into practical implementations. The role of a PCB designer goes beyond mere technical proficiency; it requires the capacity to envision how every electronic component should interact harmoniously in a real world scenario.

For your wearable scoring system, I will design a robust, low-cost, and production-ready architecture based on Nordic nRF52 series SoCs using BLE communication and Zephyr RTOS. The wearable unit will be compact, power-efficient, and highly reliable, supporting precise button interactions including single press, double press, and long press. It will also include RGB LED indication, Li-Po battery integration with efficient charging circuitry, and optimized BLE performance to ensure real-time responsiveness during gameplay. On the hardware side, I will deliver complete schematic design, carefully selected cost-effective and widely available components, and a well-optimized PCB layout suitable for both prototyping and scalable manufacturing. All design files will be compatible with industry-standard tools like KiCad or Altium. For the speaker unit, I will develop firmware to handle stable BLE communication, implement scoring logic, and trigger audio playback for accurate score announcements. The system will be optimized for reliable communication over an extended outdoor range of up to 80–100 meters. Deliverables include complete schematics, PCB files, a cost-optimized BOM, fully functional and well-documented firmware for both units, and clear instructions for build, flashing, and testing. I will also provide end-to-end support to ensure a working prototype. With my expertise in BLE, low-power systems, and Zephyr RTOS, I can deliver a scalable and efficient solution.
