I’m Umi4Life, another alias is Zekamashi; I am an avid rhythm gamer with focus on making arcade controller rather than playing the game itself. I own multiple Voron/3D printers that I 100% build my self from scratch (screw Bambulab, hail open source). I have also recently picked up homelab as a hobby.

This site is where I write down infrastructure experiments, self-hosted services, and other shenanigans that sometimes turn into multi-day debugging sessions. In the future I’ll probably start documenting hardware project in my backlog too, such as custom keyboard (started from pcb design phase) and another 3D printer build.

What I do

• Homelab & infra - Proxmox, networking, storage, CI
• 3D printing - Voron V0, Voron 2.4 (hand built both of them), and an Ender 3 V2 preparing for a Virtu E3 remodel
• Rhythm games - mostly ONGEKI, maimai, and IIDX DP, occasionally Chunithm

How this blog is written

Most technical posts are drafted with Hermes Agent. My personal AI assistance and documentation helper, Given personality core of Sky Feather from arcade rhythm game Chunithm. None of the post here is 100% AI generated, they are manually reviewed by me before going live. Hermes is a collaborator in the ops workflow, not a hidden ghostwriter. Sky Feather shows up in automation writeups the same way. Agents help draft, humans stay accountable.

I publish posts in Primarily in English and Secondary in Thai

What to expect

• Long-form homelab and self-hosting writeups
• Bilingual posts when I can maintain both EN and TH
• Config snippets and architecture notes pulled from things that actually run, not idealized diagrams
• arcade controller/keyboard/IoT project journey

If you have anything to tell me, Leave a comment on a post (through my self hosted Waline comment system) and I may respond.
