Smart Aquarium Dosing Pump Product Development

@hamzazayyad

Hello, Your smart aquarium dosing controller is an exciting product, and it closely matches my experience in embedded systems, PCB design, industrial control, and IoT product development. I am an Electrical/Electronics Engineer with 15+ years of experience developing production-ready hardware and firmware using ESP32 and STM32. I can support the complete product lifecycle—from prototype through production-ready PCB. My experience includes ESP32 firmware, Wi-Fi provisioning, web interfaces, RTC scheduling, relay/MOSFET control, sensor integration, power supply design, PCB layout, and JLCPCB manufacturing preparation. I also develop clean, modular firmware and provide complete documentation for future maintenance. I can deliver schematics, firmware, KiCad PCB, JLCPCB-ready BOM/CPL/Gerbers, testing documentation, and enclosure integration support. I work with milestone-based development, provide regular progress updates, and use Git throughout the project. I'm comfortable signing an NDA and transferring all IP upon completion. I look forward to discussing the architecture, milestones, and production requirements. Best regards, Hamza Embedded Systems | ESP32 | STM32 | PCB Design | IoT | Industrial Automation

Hello Fish Tech Focus, at HardFault, we're excited about the opportunity to bring your smart aquarium dosing pump concept to life. Your focus on creating a Wi-Fi/Bluetooth-enabled system aligns perfectly with our expertise in IoT connectivity using ESP32, which we've honed in previous projects involving complex sensor interfaces and embedded systems. Our team can not only deliver a prototype rapidly but also offer the collective strength of diverse skills, making the journey from concept to product smoother and more robust. We believe a team approach enhances reliability and efficiency, a critical factor for retail-oriented projects like yours. To start, we suggest developing a virtual prototype followed by a breadboard test using locally available components. What specific features or challenges do you foresee in the firmware development phase? We'd love to ensure we're fully aligned with your expectations from the outset.

Hi, I have developed multiple production-ready ESP32 IoT products, handling everything from circuit design to firmware and mechanical enclosure layout. I can design your complete smart dosing pump system, starting with a validated prototype and translating it into a production-ready KiCad PCB optimized with LCSC components for JLCPCB assembly. I will program the complete firmware featuring Wi-Fi captive portal provisioning, NVS persistence, and precise peristaltic pump scheduling logic. Finally, I will model the waterproof IP54 enclosure with integrated standoffs and branding, ensuring a seamless end-to-end product ready for commercial retail. Best regards,

Hi, I can help develop your ESP32-based Smart Aquarium Dosing Pump from prototype to production-ready hardware. I will design the hardware, develop the firmware, create the PCB, prepare manufacturing files, and design a 3D-printable enclosure. The product will be modular, reliable, and ready for future commercial manufacturing. I have experience with ESP32, Arduino IDE, IoT product development, PCB design, KiCad, JLCPCB manufacturing workflow, embedded firmware, Wi-Fi provisioning, web-based device control, and embedded system integration. The design will focus on reliability, safety, ease of manufacturing, and future scalability. Proposed Approach • Build and validate a working ESP32 prototype with RTC, LCD, relay/MOSFET pump control, and Wi-Fi provisioning • Develop firmware with scheduling, calibration, manual dosing, manual prime, watchdog, brown-out protection, and local web dashboard • Design production-ready PCB in KiCad with JLCPCB-compatible BOM, Gerber files, CPL, and manufacturing documentation • Deliver complete documentation, Git repository updates, testing support, and manufacturing-ready files Deliverables • ESP32 firmware source code • Circuit schematic and PCB design • Gerber, BOM, CPL, and manufacturing files • 3D enclosure design (STEP & STL) • Documentation, calibration guide, and test reports • Complete project source files and Git updates

I'm a hardware + firmware specialist with 13+ patents in embedded systems. I've designed complete IoT products from breadboard through production PCB and 3D enclosure—exactly your workflow. I have direct experience with ESP32 (WiFi provisioning, web dashboards, FreeRTOS), KiCad PCB design, JLCPCB PCBA workflows (LCSC BOM, CPL assembly), and RTC-backed scheduling (similar to your dosing timeline logic). My SailSensor project involved sensor wireless integration and gateway design; I've also built custom instrumentation with safety interlocks and watchdog protection. I can deliver all four phases: virtual prototype validation → physical breadboard build with India-sourced BOM → production KiCad schematic/layout (JLCPCB-ready Gerbers) → IP54+ 3D-printed enclosure with branding and PCB standoffs. Full Git documentation, test reports, and support through client validation included. Ready to start Phase 1 immediately. 1. Do you have a preferred protocol for the WiFi provisioning captive portal (WifiManager library, or custom)? 2. Should the web dashboard support both mobile browser and a simple Android app, or browser-only for MVP?

Hi, I design and manufacture hardware end to end, so the full chain in your PRD is what I already do on a shipping product, not a one off. PCB: production 4 layer KiCad board, clean annotated schematics, full manufacturing outputs. [If you have a JLCPCB PCBA order, add one line here naming it.] Firmware: embedded C and C++ on 32 bit MCUs, RTC scheduling, I2C LCD, non volatile settings, watchdog and brown out handling. ESP32 Wi-Fi provisioning and a local web dashboard is a short step from what I build, and I will prove it in the Phase 1 Wokwi simulation before you commit to the physical build. Safety nets are my strong suit. On my printers I traced a floating chassis noise fault and killed it with proper isolation, freewheel diodes and grounding. Flyback across every relay coil, 10k gate pull downs, reverse polarity and overcurrent protection, pumps default off on boot before GPIO init: I treat these as hard requirements, which is exactly how your Section 9 reads. I explicitly acknowledge the Section 9 safety nets are non negotiable. Enclosure: I design in Fusion 360 and print PETG on my own machines, so your Phase 4 prototype needs no outside print vendor and I control the tolerances. Documentation and Git: I ship spec sheets, BOMs with sourcing and buffer quantities, and test notes as standard, and I keep project work in Git repositories.
