Building a Neural Interface in my Garage

How I prototyped a BCI with $400 of parts, Rust, and too much cold brew. Latency < 30ms.

## The idea High-tech, low-life. I wanted to blink and deploy. We wired an OpenBCI, wrote a Rust inference loop, streamed over WebBluetooth, and rendered in WebGPU. ### Stack - Rust + WASM - WebGPU - ONNX Runtime > latency < 50ms or it doesn't exist More soon. Code on GitHub.
