The club at 42 Paris

Read the body.
Control the machine.

Your body gives off tiny electrical signals all the time. We catch them with a laptop and some code, then use them to move a cursor, type, or play a game without touching anything. You can start with zero experience and zero hardware.

01You've seen this

You've already seen this. We just make it hands-on.

Everything below is already running in the real world, on patients and in products. What we do at the club is the laptop version: same ideas, beginner scale.

Typing with your thoughts

Chips in the brain let people who can't move control a cursor and type with their mind.

Hands that move when you flex

Muscle signals already drive prosthetic hands that open, close and grip on command.

Pointing with your eyes

On a Vision Pro you select things just by looking. A webcam can do a lighter version.

02What we do

Turn your body's signals into software you can drive.

We're the software side of neurotech. We take the tiny electrical signals your body already produces and turn them into something you can control on screen: a cursor, a game, a simulation. Lots of building and live demos, very little theory. Open to every 42 student, whatever your level.

Biosignals

Your brain and muscles constantly give off tiny electrical signals. We learn to record them cleanly, from free public datasets or a simple headset.

Making sense of it

We turn a messy raw signal into something a computer understands. The best part: you literally watch your brain light up on screen.

Eye-tracking

Your webcam can already follow your gaze and catch your blinks. No special gear, just a bit of code.

Software control

The payoff: your body controls the software. Fire in a game or flip a switch without laying a finger on anything.

No experience required

This could be you, two sessions from now.

Come as you are. We start from zero and build something you can actually run by the end.

03Formats

Four formats, all of them hands-on.

Workshops

Build something running by the end of the session: a filter, a classifier, a controlled cursor.

Talks

Short sessions on BCI, signal processing and where the field is going, from students and guests.

Mini-projects & demos

Small teams ship a focused build, then demo it live on campus. Proof over slides.

Hackathons

One weekend to control something with your brain, muscles or eyes. Best demo wins.

04First session

First workshop: Friday, October 2.

Public datasets, a webcam and a laptop: that's the whole kit.

Fri · Oct 2 · 42 Paris Workshop 01 · no hardware needed

Introduction to biosignals: controlling software with eye blinks & EMG-like signals

From a raw recording to a working control loop in one session. You leave with code that runs on your own machine.

  1. 01Load a public EEG/EMG dataset
  2. 02Visualize the raw signal live
  3. 03Classify blinks and muscle bursts
  4. 04Drive a mini-game with your signal

Join us

Curious about neurotech? Come build with us.

Neurotech Club is open to every 42 student who wants to play with biosignals, BCI and human-machine interaction. You don't need any background. Everything happens on our Discord: workshops, demos, questions and the people building it all.
