About Me

Hi, I’m KYO — a Software Engineer based in Tokyo, currently living with my wife and our cat.
My cat

My mother tongue is Hakka. I also speak Cantonese and Mandarin, and taught myself Japanese and English along the way.

When I’m not coding, you’ll find me hiking in the mountains, out on a run, or tinkering with computers, cloud infrastructure, and the latest in AI.

My old Raspberry Pi 2B

OpenClaw on Raspberry Pi

Today I finished setting up OpenClaw on a Raspberry Pi (Pironman 5 case), and it is now running as an always-on personal assistant node.

The setup includes:

  • OpenClaw Gateway running as a systemd service
  • Discord channel integration
  • SSH + GitHub deployment workflow
  • Hardware monitoring for CPU/GPU temperatures

Here are a few photos of the Raspberry Pi setup:

I’ll continue improving this node and use it as a lightweight, always-on automation assistant.
