Honestly, I still prefer AI over SI — just like I still prefer Twitter over X.

Recently, I’ve been watching a Korean show called The Community (사상검증구역: 더 커뮤니티, 2024).

Really interesting. :)

What if what we see is only a shadow of reality?

AI can build faster.

But I still sketch products and UI with pen and paper.

It helps me think.

Haha~ What’s this?

2026.09.19 PCB soldering vlog

Solder paste → component placement → hot plate reflow → multimeter testing → firmware flashing.

Accidentally knocked over the already-soldered ESP32-S3…

Everything worked in the end, and the display is finally alive.

Video sped up 16×.

Turns out the ear piercing I got in middle school is still open. Just tested it with a 330Ω resistor :)
