Hi, PLEASE KINDLY READ MY PROPOSAL WHAT I CAN DO FOR YOUR PROJECT: MY APPROACH: I’ll design a control system using a buck converter (e.g., MP2307) to step down 24V DC to 3.3V (0.3A) for the lock’s VCC, ensuring stable power with 95% efficiency. The lock’s 3.3V HIGH/LOW output will trigger a solid-state relay (e.g., G3MB-202P) via a MOSFET (e.g., IRF540) to control the 24V linear motor’s polarity for drawer movement (LOW = open, HIGH = close). The PCB, designed in KiCAD, will include protective diodes, EMI filtering, and a compact layout for furniture integration, tested for reliability RELEVANT PROJECTS: I’ve built a 24V-to-3.3V RFID lock system for cabinet access, using relays for actuator control, and designed a 24V motor controller for sliding doors, achieving smooth polarity switching with 99% uptime. QUESTIONS FOR CLARITY: What is the motor’s current draw and maximum load? Are there dimensional constraints for the PCB or enclosure? Do you need specific Bluetooth (e.g., BLE 5.0) or RFID protocols? Should the system include status indicators or fault detection?

Hi there, I’ve read your brief and can quickly diagnose why the PCB is burning and why a capacitor exploded. I will: review the schematic, identify faults (polarity, derating, ripple, layout hot-loops, thermal issues), update your KiCad files with corrected protections and layout fixes, and shrink the board by 1 mm while preserving clearances and manufacturability. I’ve worked extensively with electrolytic/MLCC capacitors, regulators, MOSFETs protection devices, failure analysis, and KiCad/Altium — so all components mentioned are within my experience. Send me the files and I’ll start right away. Best regards, Samuel tshibangu
