inbannable/README.md

inbannable / William Xu — systems, signals, machines. Build quietly. Make it work.

I build software that listens, decides, and moves — from real-time audio and robot control to Apple-platform apps and interactive simulations. I care about the signal path, the control loop, and the assumptions between input and action.

01 / selected work

INTERFACE / WATCHOS

腕问 · WristAsk

An AI assistant on your wrist. Dictation, handwriting, or keyboard in; streaming DeepSeek responses out.

Swift · SwiftUI · WatchConnectivity 		SIGNAL / SPATIAL AUDIO

EchoRadar v2

Native 5.1/7.1 game audio mapped onto a 24-sector radar. Direction from multichannel signals, without inventing it from stereo.

C++20 · WASAPI · STFT · DirectX 11
CONTROL / SIMULATION

Turret Lab

A browser lab for direct PID and cascaded control. Same plant, target, and disturbance; different control loops.

TypeScript · React · Control systems 		MOTION / ROBOTICS

Orion · FRC 6940

Robot software for aiming on the move, turret control, dual-encoder positioning, vision fusion, and autonomous routines.

Java · WPILib · AdvantageKit · PathPlanner

02 / side channels

  • 星阵 · 3D Gomoku — Gravity-aware 5×5×5 connect-four, with a strategy AI and move coach.
  • Director's Cut — A server-authoritative Minecraft story director for events, hints, and controlled chaos.
  • Conway's Game of Life — Small rules. Emergent behavior. Runs in the browser.
