Before You Begin

📦 Kit Contents

  • Knight Board with USB-C cable
  • EEG headset with 8 dry spike electrodes
  • 4 comfort electrodes
  • Ear clip and conductive paste

💻 Prerequisites

  1. Download the EXG Visualizer
  2. Disable Hardware Integrity protection on Windows 10/11

Setup & Installation

Headset Setup

1
Choose locations for the dry spike electrodes (Fp1 and Fp2 are recommended starting points).
2
Place the 4 comfort electrodes opposite the dry spike electrodes for balance.
3
Screw all electrodes in lightly so they sit flush with the headset frame.
4
Wear the headset and ensure the midline is centered between the eyebrows. Tilt it so the Fp1/Fp2 nodes sit just above the eyebrows.

5
Fasten the chin strap snugly.
6
Tighten the comfort electrodes in a star pattern.
7
Tighten the dry spike electrodes in a star pattern. Ask for help if needed.
8
Apply conductive paste to the earlobe and attach the ear clip.

Knight Board Setup

1
Connect the board to your computer using the USB-C cable.
2
Open the EXG Visualizer and select your device from the dropdown menu.
3
Activate channels one by one, waiting briefly between each.
4
Toggle all RLD checkboxes.
5
Turn off unused channels by switching them toward the headers.

6
Connect the electrodes to the positive rail of the active channels.
7
Attach the ear clip to the RLD/COMM headers.

✅ Verification & Testing

Signal Check:

  • Clench your jaw — all channels should spike together synchronously.
  • Close your eyes — look for alpha waves or slow oscillations.

🚩 Troubleshooting

Board not detected?

  • Disable Hardware Integrity protection in Windows.
  • Ensure the Arduino board is properly seated in the Knight Board.

Noisy data?

  • Re-seat the electrodes properly.
  • Make sure unused channels are turned off.
  • Avoid rooms with heavy electronics or AC power interference.
  • Check all physical connections.
