Hi, my name is

Tu Chenguang.

Welcome to
my world.

I'm a first-year Electrical & Electronic Engineering student in Malaysia, originally from Hangzhou. This site is where I track how I grow, plus a few things I built on my own.

See what I'm building

01.About

Hi! I'm Tu Chenguang. Since September 2025 I've been studying at Xiamen University Malaysia (XMUM), majoring in Electrical & Electronic Engineering (EEE).

Hangzhou, Zhejiang is home. Graduated from Hangzhou High School.

Still figuring out what's next — grad school in China or abroad, both on the table. This site is where I keep notes on how I grow, and the projects I have fun with along the way.

Outside of all that — basketball, swimming, travel, motorcycles. Long game: financial freedom first, then the rest of the world.

Currently working with:

  • Python
  • JavaScript
  • C / C++
  • React
  • Supabase
  • Tailwind CSS
  • Vercel
  • Git

02.Things I've made

2026.4

Pocket Ledger

ledger.tuchenguang.com
After moving abroad, money kept slipping through my fingers — different apps on different platforms, no clear picture of where it all went each month. Every ledger app I tried locked the useful features behind a paywall, so I built one for myself: multi-currency entries, stats, budgets — all free. The hosting bill is small enough that I can carry it for now.

Billiards Scorer

billiards.tuchenguang.com
Playing chase-the-score with classmates, every billiards-scoring app I tried was either backwards or stuffed with ads. So I wrote one.

Class Calendar

calendar.tuchenguang.com
My university hands out far too many deadlines and has no unified place to track them, so I built one that catches them automatically.

ESP32-P4 Smart Vision Terminal

DNESP32P4 + ESP32-C3 dual-MCU smart terminal for a school embedded-systems competition. The P4 runs local vision, audio and HUD; the C3 isolates the network stack. Voice loop = Whisper → GPT-4o → streaming TTS; GPT can also function-call into 7 tools (take_photo, get_weather, set_timer, …). Full dev log in the blog.

Algorithmic trading system (shelved)

A backtesting system for BTC/ETH/SOL built around a symbolic-AI rule engine. Running it 24/7 needs a hosted server, and that cost dwarfs my actual capital; without a connectionist model and the compute to back it, the system can't read regime shifts in the market well enough to trust.

Polishing Pocket Ledger

Steady polish on the existing build — bilingual UI, data export, budget visualizations, and interactions that just feel more obvious.

● In progress

Polishing the deadline tracker

Currently in closed beta — it'll open up to everyone before long.

● In progress

PCB-art generator

No AI — just Python. The user uploads an image; the script separates colors, simplifies the shapes, and outputs a PCB .zip ready to send straight to JLCPCB.
