HimC29/README.md

Hi, I'm Him C. waving hand gif

Self-taught developer from Malaysia who enjoys building embedded systems, full-stack web apps, and hardware projects.

Most of my projects start as experiments and slowly turn into something more complete than I originally planned.

🐧 Arch Linux user • 🔧 Hardware tinkerer • 🎵 Embedded systems enthusiast

🌟 Featured Project

🎵 HC-SoundBox

A custom ESP32-based music player with an OLED screen, SD card storage, physical buttons, custom screensavers, and dedicated audio hardware. It started as a simple idea to play music and gradually turned into a fully usable standalone device.

What I worked on:

  • ESP32 firmware development from scratch
  • Building an OLED-based interface
  • Handling audio playback from SD card
  • Designing physical controls (buttons/navigation)
  • Making everything run smoothly on limited hardware
