One engineer building a brain-computer interface from raw EEG up. No hype. No fake authority. Just the work, in the open.

WHAT THIS IS
NEURON_SCHEMATIC_V2.1
SCALE: 1:1 | REVISION: A
Brain-computer interfaces get cheaper and more open every year. Most of the coverage is hype, written for people who will never build anything.
This is the opposite: a real build, real skepticism, and what a working engineer should actually do about it. I document every step here, including the parts I get wrong.

SECTION_03::THE_NEUROCIRCUIT
THE NEUROCIRCUIT
The signal, minus the noise.
Every issue: what actually moved in BCIs, biosensing, and neuroengineering, why it matters, and what to build or learn next. When something's overhyped, I say so.
