Über mich
I build and debug small embedded hardware projects where the circuit and firmware must work together. I work with ESP32/ESP32-S3, sensors, relays, motors, RS485, audio input, custom PCBs, and firmware. I have built an AI companion device prototype base with microphone input, sound source localization, smooth S-curve servo motion, local device logic, and educational interaction flows. Send me your idea, schematic, PCB files, photos, or error logs. I will help you check the problem step by step.... Mehr lesen

I work on small embedded hardware projects that combine circuit design, PCB design, firmware, sensors, motors, relays, RS485 communication, audio input, and ESP32 based control systems. My project experience includes custom control boards, firmware debugging, sensor integration, motor and relay control, and an AI companion device prototype base with microphone input, sound source localization, smooth S-curve servo motion, local device logic, and educational interaction flows. I focus on practical hardware that can be built, tested, and improved step by step.
