SKILL TREEBuild it for real

One destination, one subsystem at a time: schematic, layout, fabrication, and bring-up. Follow the path from your first board to a brain-computer interface.

Flagship path

The 8-Channel EEG

The flagship: the analog board that reads real brainwaves. The brain-computer interface, and the shortest path to it.
