I need an experienced hardware designer who can turn my concept for a cylindrical, flashlight-style RGBW 'beacon' into a working, weather-resistant prototype. It has to shrug off rain and humidity with an IP-rated enclosure, remain visible in full sun or heavy cloud, and run from a rechargeable battery. Smooth, precise brightness control is critical—I want remote dimming and color mixing over Wi-Fi, not just simple on/off states. Core requirements • Cylindrical housing (roughly flashlight form factor) with a frosted diffuser above the LED stack, all components housed inside the cylinder • High-output RGBW LED module, optics chosen for daytime visibility • On-board Wi-Fi (ESP32 or similar) for wireless control and OTA updates • Rechargeable battery can be 21500 • Electronics and sealing strategy that survive rain, humidity, and heat on a turf field. • Firmware API or simple web endpoint so I can issue color/brightness commands remotely Ideally prototype cost is below $50, can assume wholesale pricing, 60$ at the most. Deliverables 1. Schematics, PCB files, and bill of materials 2. 3-D CAD of the enclosure, including gasket and fastener details 3. Firmware source with documented Wi-Fi control endpoints 4. One fully assembled, tested prototype shipped to me Acceptance criteria • Beacon maintains full brightness for at least 4 hours on a single charge • LED remains clearly visible at noon on an overcast/sunny day from 30 m+ • Unit passes a 30-minute garden-hose spray test with no leakage • Wi-Fi control latency under 300 ms for colour/brightness changes If you have a proven track record with outdoor IoT lighting, let’s discuss timelines and any suggestions you have on parts selection or thermal management.

Hi, Thank you for the detailed project description—I’d be excited to develop your cylindrical RGBW “beacon” from concept to a fully tested, weather-resistant prototype. I specialize in outdoor IoT lighting, ESP32-based electronics, IP-rated enclosures, and battery-powered LED systems. Your requirements align closely with projects I’ve delivered before. My Approach: • Engineer a high-output RGBW LED module with proper optics for 30 m+ daytime visibility, including thermal path and heat spreading. • Design the enclosure with a frosted diffuser, sealed interfaces, gaskets, O-rings, and IP-resistant fastener strategy suitable for rain and humidity. • Develop a compact ESP32-driven PCB with precise PWM control for smooth brightness and color mixing, OTA support, and battery management for a 21500 cell. • Ensure 4+ hour runtime at full brightness through LED efficiency + thermal/battery optimization. • Provide firmware with clean REST/Web API endpoints for remote color and dimming control with <300 ms latency. Deliverables: – Full schematics, PCB layout, and BOM (optimized for <$50–$60 target) – 3D CAD of enclosure with sealing strategy – Firmware source code with documentation – One assembled and tested prototype, including spray-test validation I’d be happy to discuss part selection and thermal considerations in more detail. Looking forward to collaborating with you!

Hello, I will turn your cylindrical RGBW beacon concept into a rugged weatherproof prototype powered by a rechargeable cell. The design keeps all electronics inside a flashlight-style cylinder with a frosted diffuser and an IP-rated seal. I’ll pick a high-brightness RGBW module and optics for daylight visibility, plus an ESP32 Wi‑Fi core for remote control and OTA updates. The firmware will expose a simple web API for color and brightness with fast response. A 21500 battery fits inside and I’ll plan a safe charging method to give at least four hours of bright operation. Deliverables include schematics, PCB files, BOM; 3D CAD of the enclosure with gasket details; full firmware with endpoints; and one tested prototype shipped to you. I’ll tailor parts and heat path to survive rain, humidity, heat, and hose spray tests, and meet your 30 m visibility goal. Do you have a target IP rating (e.g., IP65) and operating temperature range for field use? Is a 21500 mAh battery acceptable and what charging method do you prefer (USB-C, plug-in, or solar option)? Which control protocol do you prefer for remote commands (HTTP REST, MQTT, WebSocket) and what security needs should I meet? Any enclosure material or gasket preferences, and any tolerance constraints for the diffuser and optics? Are there any extra tests or standards you want beyond the garden-hose test (temperature cycling, vibration, IP certification)? Best regards,
