USB PD EPR Lab Tokyo, or sometimes Shenzhen

Once I learned chargers "talk" to devices, I—a complete novice who didn't even know Python—couldn't resist eavesdropping on USB PD EPR. So I hoarded gear, built custom tools, and set out to fully expose their secrets! 😎

[Timeline]
Mid-Mar: Hooked on PD communication.
Late-Mar: Lost all self-restraint.
Apr: Panic-bought gear (reckless run to Huaqiangbei).
May-Present: Started Python/C/electronics from scratch. Building custom sniffers & scripts! 😆
