I need an experienced electronics / PCB engineer to design a reliable 24/7 traffic light controller PCB. This is a safety-critical industrial system, not a hobby project. System Details: 220VAC traffic light LED modules Control via TRIAC (optocoupler + TRIAC driver) Continuous 24/7 operation ESP32-based control Fail-safe design required Industrial-grade AC mains design Using EasyEDA PRO Requirements: Strong ESP32 hardware experience Experience with AC mains / TRIAC design Experience with industrial / high-reliability systems Comfortable designing fail-safe protection systems Timeline (strict): Day 1: Complete schematic Day 2: PCB placement & routing If it takes longer, it means you are not experienced enough — this is not a complicated project. You must be ready to start immediately after award. Please check attached image. PCB1 is the main controller board, and additional expansion boards (PCB2) will connect to it. Only bid if you can start right now.

As an experienced Embedded Systems Engineer, I am confident that I am the best candidate for your project. I have a strong background in electronics and PCB design, which makes me well-versed in your specified TRIAC traffic light controller system. With my familiarity of ESP32 and robust hardware designing skills, I can ensure a 24/7 operation that aligns with strict timelines. My competence with KiCad and other related tools will allow me to efficiently complete the schematic of your PCB within day one of the timeline, and follow day two with precise PCB placement & routing. I take pride in my ability to adhere to schedules without compromising quality. Furthermore, my understanding of industrial-grade AC mains design and experience with fail-safe protection systems equip me to create a reliable and safe traffic light controller PCB. Safety and reliability - two aspects crucial for your project - remain the central theme of my work. I assure you I am ready to start immediately and provide consistent communication throughout the project. Let’s proceed with our collaboration to craft an end-product that meets your highest standards at all levels!

Hi, I’ve reviewed your TRIAC-based ESP32 traffic light controller needs for 24/7 operation in an industrial setting. I’ll design a robust, mains-ready PCB with fail-safe features, clean isolation between the AC mains section and the ESP32, and a clear triac/optocoupler interface for reliable switching of 220VAC LED modules. The approach is to lock down a clean, fault-tolerant schematic first, then lay out the PCB with careful creepage/clearance, robust decoupling, and watchdog/monitoring paths. I’ll deliver a compact main controller (PCB1) with concise expansion support (PCB2) ready for EasyEDA PRO. What specific fail-safe state handling and fault monitoring are you expecting for 24/7 operation, and is there a preferred redundancy strategy for the expansion boards? Best regards, Marko Aleksic

Hello, I have reviewed your requirements for the industrial traffic light controller and I am ready to start immediately. I am an experienced PCB designer specializing in embedded systems and AC mains applications using EasyEDA Pro. Why I am the right fit: Industrial AC Design: I am well-versed in 220VAC control via TRIACs (using optocouplers like MOC30xx series) and understand the critical importance of snubber circuits, isolation slots, and correct creepage/clearance rules for safety. Safety-Critical Logic: I will implement hardware interlocks in the schematic to prevent conflicting states (e.g., Green-Green active simultaneously) ensuring a fail-safe operation. ESP32 Expertise: I have extensive experience with ESP32 hardware design, including EMI mitigation and stable power delivery for 24/7 operation. The 2-day timeline is realistic for this scope. I can deliver the complete schematic by tomorrow and the finished layout/routing on Day 2 as requested. Best regards,
