ESP32-Based Compact Water Cooling Device with LCD Interface

✅ Project Description for Freelancer.com:
I'm looking for an experienced electronics engineer or mechatronics engineer to assist with the complete design of a compact water cooling and filtration device using an ESP32 Mini microcontroller and an LCD or OLED display. The system will involve multiple Peltier modules, a water pump, filtration loop, temperature and flow sensors, and real-time status display.

The goal is to prepare the entire system for prototype manufacturing — all deliverables should be clean, well-documented, and production-ready.

? Key Deliverables:
Complete electronic schematic

Full Bill of Materials (BOM) with part numbers and alternates

Detailed wiring diagram

Microcontroller logic and sensor handling plan (pseudocode or flowchart)

Display integration (OLED or LCD) with real-time temperature and alerts

Component selection for:

Peltier modules

Heatsinks/cold plates

Cooling fans

Mini water pump

Filtration unit

Power supply (battery or adapter)

Sensors and microcontroller

Thermal management strategy

Basic 3D layout guidance or CAD support for component placement

Final ready-to-send package for prototype manufacturing

Optional: Brief technical notes or suggestions for improvements

✅ Ideal Skills & Experience:
Experience with ESP32 Mini or equivalent microcontrollers

Knowledge of Peltier cooling systems and power management

Experience integrating sensors and displays (LCD/OLED) in embedded systems

Strong documentation and schematic drawing skills

Basic CAD experience or layout planning for compact devices

Understanding of thermal dissipation best practices

Please submit your bid if you're confident you can deliver high-quality work and are available for a short project with clear scope and milestones.

Looking forward to working with a creative and technically skilled engineer.
