About Chaosgoo
Chaosgoo is an independent technical blog created and maintained by Chaos Goo.
I publish original, hands-on articles about embedded systems, electronics, and projects that combine hardware and software. I write, edit, and maintain the content based on my own development and engineering work.
The site is actively maintained, and I intend to keep publishing here. It is not a scraped-content or aggregation site.

About me
Hi, I’m Goo (Chaos Goo). I like building things myself.
This blog records experimental code, debugging notes, design decisions, and what I learned while working on real projects.
Tools and technologies
| Area | Tools and technologies |
|---|---|
| Embedded development | ESP32 / ESP-IDF / ESP8266 / WCH (CH58x/CH592) / Arduino |
| GUI frameworks | LVGL / FreeType / TFT_eSPI |
| Smart home | HomeKit / Home Assistant / MQTT |
| Mobile development | Android (Kotlin / Flutter) |
| Hardware design | KiCad / Fusion 360 / 3D printing (Bambu Lab P1SC) |
| Version control | Git / GitHub |
I work on low-cost microcontroller projects from PCB design and soldering through firmware development. Lately I’ve also been exploring low-power WCH chips, BLE, and e-paper displays. When recreating game props, I try to reproduce their behavior as well as their appearance: lighting, sound, and interactive animations.
Some of my projects
| Project | Description | Link |
|---|---|---|
| ESPFlash | An Android tool for flashing ESP32 devices | Google Play |
| SerialFlow | An Android serial monitor with search and filtering | Google Play |
| PixelCompass | A Minecraft compass built around a CH592F, with web-based configuration | Article |
| CS2 HealthPin | A physical health badge synchronized with CS2 through GSI | Article |
| Friday Ink | A CH582F e-paper clock with approximately 3μA sleep current | Article |
| LVGL and FreeType | Variable font weights on ESP32 | Series |
I use a Bambu Lab P1SC for custom enclosures and mechanical parts, and Fusion 360 for modeling.
