MY PROJECTs 私のプロジェクト
Normally I build things without purpose. from ground up or upgrading other creators projects. but the real enjoyment for me comes from solving a problem even with one line of code.

Open hardware and embedded tools, mostly ESP32, mostly RF. Built from scratch, or upgraded from someone else's idea.
Multi-band wireless toolkit, Wi‑Fi, BLE, sub‑GHz, IR, RFID/NFC, GPS on one touchscreen handheld.
A Rubber Ducky reimagined on ESP32-S3, BadUSB scripting with wireless control.
NRF24-based toolbox for 2.4GHz analysis, jamming, and protocol spoofing.
Sub‑GHz swiss-army tool, capture, replay, and jam remotes and garage doors.
A virtual pet that reacts to the Wi‑Fi and BLE devices around it.
Local network ARP-based reconnaissance and monitoring tool.
Visual UI designer that exports layout code straight into embedded projects.
Real-time 3D Earth disaster globe, CesiumJS + live NASA/USGS/NOAA feeds.

Embedded systems, RF security, and open hardware, walkthroughs, teardowns, and things you probably shouldn't try at home.
Deep dives on hardware, security, and open-source builds, the long-form stuff behind the projects.
