Low-Power Thermal Profiler Problem: Traditional profilers needed batteries, increasing maintenance in high-temp environments. Solution: Designed STM32L4-based thermocouple profiler with USB, I2C, SPI, RTC interfaces. Result: Achieved battery-free operation through ultra-low-power optimization. Industrial Reflow Oven (4th Gen) Problem: Required a modern, certified industrial control unit with high-precision data logging. Solution: Developed STM32F4 HW/SW with a 5" graphical display and SPI/I2C USB PC data t

Mitutoyo Linear Scale Integration into SCADA Problem: SCADA systems cannot directly process raw signals from Mitutoyo digital gauges due to their closed, proprietary communication protocol. Solution: Designed dedicated HW & SW to decode the proprietary Mitutoyo protocol and bridge data into SCADA architecture. Result: Enabled seamless real-time data capture and automated measurement logging within the main SCADA environment. Line Scan Camera Signal Processing Problem: High-speed camera inspection required

Audio & Signaling Systems (8051 MCU) Problem: Playing uncompressed WAV audio and managing chime signals on legacy 8051 microcontrollers was constrained by limited memory bandwidth and strict EMC compliance limits. Solution: Co-designed system architecture, built custom FLASH memory reading logic for WAV playback, and developed control software using Keil C. Result: Achieved reliable audio playback on a low-resource MCU platform and successfully passed EMC certification.
