Neuro PlayGround Lite (NPG Lite) Ninja Pack is fully open source and pre-assembled, ready-to-use biosensing kit designed for those who want to dive straight into Human-Computer Interface (HCI) and Brain-Computer Interface (BCI) projects. It combines the NPG Lite board with the VibZ Playmate, all enclosed in a custom 3D-printed case with a built-in battery — giving you a smooth, plug-and-play experience without compromising flexibility or performance.

The VibZ Playmate adds a vibration motor for haptic feedback, a buzzer for auditory feedback, a QWIIC port for I2C sensor integration, an ON/OFF slide switch, and 2.54 mm electrode header pins with a common negative electrode option. This modular setup lets you easily customize your configuration for research, education, or biofeedback experiments.

Why We Call It the “Ninja Pack”

Ready in a Flash: The Ninja Pack is all about speed and stealthy setup. It comes fully assembled in its own protective case, with the battery already installed and connected. There’s no wiring, no fuss—literally just turn it on and start exploring.
Feel and Hear Your Signals: The included VibZ Playmate has a tiny vibration motor and a buzzer. This means you can create projects that give you real-time feedback—like a gentle pulse that matches your heartbeat or a buzz when you flex a muscle. It brings your data to life!
Cut the Cords: Like any good ninja, you don’t want to be tied down. The NPG Lite board is wireless and sends data over Bluetooth or Wi-Fi, giving you the freedom to move around and build cool wearable gadgets.
Grab and Go: The durable 3D-printed case and internal battery make this a truly portable lab. Slip it in your bag and take it to a classroom, a workshop. It’s always ready for your next flash of inspiration.

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.
