TL;DR — I built a bullet train sushi robot control stack for Zenpo Sushi.
The mobile UI is a Flutter app that drives a Wi‑Fi robot over simple HTTP commands; the firmware is Arduino (WiFiNINA) orchestrating dual motors, a Hall sensor for position, a hardware Return/Home button, and idle‑safety logic. This post walks through the architecture, the code, and the production hardening plan.

I have become increasingly convinced that we are witnessing the formation of a new subprime mortgage bubble. Drawing parallels to the dynamics that led to the devastating financial crisis of 2008, fueled by rampant subprime mortgage issuance, I see a similar storm brewing due to the aggressive overissuance of DSCR (Debt Service Coverage Ratio) loans.
