Hi there, I carefully reviewed your Eye Massager project, including pneumatic pressure control with valves, heating pads, vibration motors, Bluetooth audio/connectivity, physical user controls, and integration into the enclosure you will provide. I am a mechatronics engineer with almost half a decade of experience in embedded electronics, PCB design, power supplies, hardware prototyping, sensors, actuators, and electromechanical system integration. My background is well suited to reverse-engineering the reference device functions and developing a compact custom PCB rather than relying on a larger development board where a dedicated design would be more appropriate. I can handle the hardware architecture, schematic, compact PCB layout, component integration, manufacturing files, and prototype-oriented hardware development efficiently because these areas are already part of my core skillset. I should mention that I am based in Tunisia, so I would be suitable if remote collaboration is acceptable despite your preference for someone located in Ahmedabad. Please send me a message so we can discuss the project and start. Best regards, Samuel tshibangu

Hi, I can develop the **Eye Massager PCB, firmware and mobile control system** based on your existing China reference unit and required functions. I have **16 years of embedded/IoT R&D experience** with custom PCB design, ESP32/MCU firmware, Bluetooth, wearable/medical electronics, heating control, vibration/motor control and compact battery-powered products. I have also completed **wearable biomedical projects including an IoT-based Naadi Analysis wearable and Bio-Impedance/Body Composition Analyzer**. I can design a compact controller integrating: * **Pressure/diaphragm + solenoid valve control** * Heating-pad control with temperature protection * Vibration motor control * Bluetooth audio connectivity * User buttons and operating modes * Rechargeable battery/power management * BLE communication with a mobile application I can first study the reference device and reproduce its required functions, then optimize the electronics for the smallest practical PCB and enclosure integration. ESP32 is a strong option for BLE and application control without unnecessarily using Raspberry Pi. Deliverables will include **assembled/programmed/tested PCB, firmware, PCB source, schematic, BOM, manufacturing files, mobile-app communication interface/source and complete project data**. I can also support prototype testing inside your supplied enclosure Best regards, Subhash Suman Embedded | Wearable Electronics | ESP32/BLE | PCB | Biomedical Devices

❤️❤️❤️Hi, I am very glad to work for you!❤️❤️❤️ ⭐⭐⭐⭐⭐⭐ I can provide expert hardware and firmware development for your Eye Massager, replicating the reference device functions on a compact custom PCB. ✔ Custom PCB design in the smallest practical form factor for your enclosure ✔ Pressure control via pressure or diaphragm valve and solenoid valves ✔ Heating control for heating pads with safe temperature regulation ✔ Vibration control for small vibration pads ✔ Bluetooth audio for sound playback from a mobile device ✔ Firmware for user control buttons and full mobile app control ✔ Complete tested package with all source, data and programs handed over I have strong experience in embedded systems, microcontroller selection, PCB layout and firmware for consumer wellness devices, with safe handling of heating and valve actuation. Do you have the reference device schematics or should I reverse engineer functions from the unit? Best regards.

I deliver 100% work — 99.9% is not for me. Workflow Diagram Reference Device Analysis ⟶⟶ Function Mapping ⟶⟶ ESP32/MCU Architecture ⟶⟶ Compact PCB ⟶⟶ Valve/Pressure Control ⟶⟶ Heating & Vibration Drivers ⟶⟶ Bluetooth/Audio ⟶⟶ Firmware ⟶⟶ Mobile App ⟶⟶ Prototype Testing Your reference device can be functionally analysed and rebuilt around a compact custom PCB rather than using a full Raspberry Pi where unnecessary. An ESP32-class architecture can provide Bluetooth/Wi-Fi, button control and mobile communication while keeping PCB size, power consumption and BOM under control. I’ll design proper driver stages for solenoid/diaphragm valves, heating pads and vibration motors with protection circuitry, temperature/current monitoring and safe switching. Firmware will manage operating modes, buttons, pressure sequences, heating limits, vibration patterns, Bluetooth communication and fail-safe states. The mobile app can expose these controls through a clean BLE/Wi-Fi protocol. Final handover can include editable schematic/PCB files, BOM, Gerbers, firmware, app source and manufacturing data. Best Regards, Asad

For the design aspect, my experience includes market research, careful component selection emphasizing long-term availability, and optimizing PCB layout for maximized performance. I anticipate potential thermal, reliability, and manufacturability issues ahead for your device and will address them accordingly. On the firmware side, I've developed programs for a variety of microcontrollers including Arduino, ESP32, and STM32 platforms - precisely what is needed to program your User control buttons and enable all the functions you need for the Eye Massager. Moreover, as someone based in Ahmedabad, Gujarat myself, I have a strong familiarity with local suppliers which can be beneficial for timely sourcing. With me on board

@HeyAbhinav

Instead of using Raspberry Pi "board' I can design a PCB that'll have RP2040 or similar processor which can control pressure, heating, vibration and bluetooth connectivity for sound. I understand the requirement as I developed a solution for a company's massage mattress product and I know my experience will be of use here. Everything can be controlled through a mobile application, though I only deal with the PCB's and firmware. I will deliver you DFM/DFA tested and compliant PCB design, a firmware that you can directly upload to the board. Plastic enclosure will help me constraint the size of the PCB. I think we can have a productive deal, let's talk...

@paulpham93

I can develop the battery-management PCB and firmware for your eye massager, including protection, charging, fuel gauging, load switching, and low-power MCU control. I’ll review the reference hardware, define the power architecture, produce schematics and a routed PCB, and validate charging and thermal behavior. My Upwork profile has earned over $300,000 on Upwork with account Paul.P. Best regards, Paul.
