Neuro PlayGround Lite (NPG Lite) Explorer Pack

Neuro PlayGround Lite (NPG Lite) is a compact, Feather-form-factor wireless biosignal acquisition board designed for research, education, and wearable applications. It supports ECG, EMG, EOG, and EEG recordings, making it a versatile tool for exploring human-computer and brain-computer interfaces.

With its multi-channel BioAmp, wireless connectivity (Wi-Fi, BLE, Zigbee, Thread), and battery operation, NPG Lite ensures portability, quick setup, and a clutter-free experience. You can expand its capabilities with Playmate add-on boards or FeatherWings, enabling features like haptic feedback, audio alerts, and more.

NPG Lite, with its multi-channel BioAmp, wireless connectivity, battery operation, and expansion interface, allows users to create HCI and BCI applications with ease. We’ve created four demos leveraging ECG, EMG, EOG, and EEG singals to inspire you, but the possibilities cover so many more use cases.

Neuro PlayGround Lite (NPG Lite)  is fully open source and integrates seamlessly with the Chords software suite for real-time visualization, filtering, and analysis of bio-physiological signals. From building gesture-controlled devices and brain-driven games to experimenting with EEG meditation apps or assistive technologies, the possibilities are endless.

Make Muscular Music

This is a human-computer interface (HCI) that uses 3-channel EMG data to detect muscle signals from the left hand, right hand, and chest to control virtual musical instruments. When muscles contract, each channel triggers a distinct sound effect, transforming your body into an organic orchestra.

DEMO VIDEO:

Track Your Heartbeat

This demo focuses on capturing electrocardiogram (ECG) signals to calculate heart rate using Neuro PlayGround Lite and displaying them in a Chrome-based browser on a mobile phone in real-time via a Bluetooth LE connection.

Jump In the Blink of an Eye

Instead of using the keyboard, you can control a game simply by blinking. The setup detects EOG signals from the eyes, sends the data over Bluetooth LE to the PC, detects eye blinks, and then takes the eye blink as a trigger to emulate the spacebar keystroke. You can configure the code to simulate any other keystroke as well.

Pop Bubbles With Your Mind

This demo showcases a brain-computer interface (BCI) application that utilizes EEG (electroencephalography) signals to operate an interactive bubble-popping game in a web browser. The system identifies beta wave activity (12–30 Hz), indicating concentration and attention levels. Bubbles appear and pop as the user maintains focus, but they cease to pop when concentration wanes.

EEG + ECG Assistive Meditation App:

EEG for brain data and ECG for HRV analysis to guide and enhance mindfulness through real-time brain-heart coherence
