Expensive hardware
Commercial EEG systems are often priced for labs, not students trying to build their first working project.
Open tools for learning brain signals
Build brain-computer interface projects like Arduino projects with affordable EEG hardware, beginner-friendly tutorials, and open tools for learning brain signals.
The problem
Commercial EEG systems are often priced for labs, not students trying to build their first working project.
New builders have to learn electrodes, noise, sampling, filters, and software before they can see a useful signal.
Most tools assume prior neuroscience or signal processing experience, which makes early projects feel out of reach.
The product
A hands-on kit for recording, visualizing, and decoding brain signals while learning the electronics underneath.
An Arduino-style hardware base for sampling EEG signals and experimenting with real-world biosensing.
Starter-friendly accessories so learners can focus on setup, signal quality, and repeatable experiments.
See live EEG activity, inspect noise, and understand how filters shape the signal before decoding it.
Step-by-step lessons designed for engineering students, neuroscience students, and curious makers.
Why Lepa
Unlike black-box EEG products, Lepa teaches how the signal works: electrodes, amplifiers, filters, ADCs, noise, and decoding. The goal is not just to use BCI hardware, but to understand it well enough to build with it.
