About Conscious Labs
Conscious Labs has been working since 2014 on taking neuroscience out of the lab and into the wild. They bring the technology, the team and the expertise to integrate EEG sensors into head wearables and hearables.
We are very excited to partner with Conscious Labs to offer this affordable, high-quality biosensing kit to our community. The ThinkPulse™ kit offers research-grade dry, active electrode EEG sensors at an unprecedented price point and comfort level.
ThinkPulse™ is a product of Conscious Labs (France). Patents issued and pending. Made in France.
The ThinkPulse™ system is an add-on to the Ultracortex EEG Headset plus Cyton Board This kit has been designed and its compatibility tested for the 8 and 16 channel Ultracortex with OpenBCI Cyton/CytonDaisy boards. For more compatibility and customization options as well as general product questions, please contact us support@openbci.com..

Note, the replacement set $99.99 is just for those who want backup electrode tips. The Starter Kit $349.99 includes the necessary electrodes and electrode tips.
How to Use the ThinkPulse Starter Kit with the Ultracortex Headset
Below is the step-by-step tutorial by Conscious Labs on how to install the ThinkPulse Starter Kit on the Ultracortex. If you are doing this for the first time, allow yourself 20 minutes to put it together. You may briefly need a soldering iron and soldering wire at Step 3. If you do not have a soldering iron, you can still assemble the ThinkPulse! Keep reading for the solder-free option.
Step 1: Prep Your Ultracortex Mark IV EEG Headset
Step 2: Install the ThinkPulse™ sensors on the Ultracortex
Step 3: Assemble the ThinkPulse™ Power Supply Board
The assembly video shows how to install the power supply board to a post-2018 Cyton and a pre-2018 Cyton.
Some early ThinkPulse units have a hardware bug. The fix is a straightforward, quick solder job. The first minute of the video explains how to do it.
ThinkPulse kits that shipped post-January 2021 are fixed and do not require soldering. If you need help or have any questions, email support@openbci.com
Step 4: Connect and organize the cables
Step 5 (For 16-channel kit) Connect and organize the cables
Using the ThinkPulse™ sensors with OpenBCI Cyton Board
The following information applies specifically to Cyton and Cyton+Daisy Boards. If you are seeing RAILED in the GUI, try the following tips:
- Disconnect the BIAS earclip from the Cyton board.
- Go to the Hardware Settings (button is found above Time Series widget) and turn BIAS and SRB1 to
NOandOFF. - Keep SRB2
ON. - For every channel, set the GAIN to '8' or less.
- Below, you will find a screenshot of what this should look like in the GUI Hardware Settings. If you are communicating directly with the Cyton, the command correlating to this picture would be
x1040010X. - Pressing the
Savebutton at the bottom of the Hardware Settings will allow you to store this configuration as a file. - Next time you want to use the Cyton with ThinkPulse Electrodes, open Hardware Settings to
Loadand thenSendchannel settings. If you are using BrainFlow outside of the GUI, simply send these commands after instantiating the Board.
