Hello G,
Thank you for your post. We are currently experiencing some issues when running Cortex on the new Pi OS. Please install and use Raspbian 10 version 2020

Hello Max. Thank you for your post. For the headset to work, it requires the two reference sensors to be connected to a human. When the headset is turned on but not on a wearer’s head, clearly this condition is not met and the electronics float on the room noise, which can be huge! EEG signals are measured in microvolts – that is, one-millionth of a volt. Any object in a normal 21st Century room oscillates in synch with the electrical power circuits, transformers, motors, power supplies, phones, wireless transmitters of all kinds and also massive electrostatic signals. The scale of these variations is huge – electrostatic signals can be 20,000 volts without any problem, room pickup can be several volts. All of these signals mashup in the electronics and generate random noise in the circuits which can’t be canceled unless our noise circuits are properly connected. Unfortunately, the thing about random noise is that it tends to look a lot like just about anything else at some time or other, so the contact quality detectors will sometimes fire up randomly as well and the application will show activity. The headset will work perfectly when fitted, but randomly when the noise cancellation circuit is disconnected. It is not a sign of a faulty headset. Every known EEG system including $60,000 medical units will behave the same way.
If you have other questions, please let us know.

Hello Girard, Thank you for your post. Please refer to this link for the picture on how to pack the INSIGHT headset in its case – https://emotiv.gitbook.io/insight-manual/quick-start/package-contents. The other accessories can fit in the mesh pocket in the case. You do not need to pull out the sensors but you will disassemble the headband into two parts. Hope this helps. If you need anything else, please let us know.

Hello Shubham,

sudo systemctl <span class="hljs-built_in">status</span> cortexHello Jordan. Thank you for your question.
<div data-snippet-id=”1367734″>The EQ map is measuring the quality of the brain signal for each sensor, and it takes into account movement, noise, signal amplitude, and many other parameters that make it much more sensitive. It is totally normal for the EQ to flicker and it DOES take time for the signal to settle, so adjust each sensor individually, sit still and wait patiently for 3-5 seconds. If the signal flickers green at any point, it’s likely the signal is good, but it is imperative to sit still to see if it maintains the green.</div>
<div></div>
<div>It is expected that the EQ signal will flicker – this is an indication that we are detecting movement, noise, or other interferences that mean the brain signal is not perfect. To reiterate, it behaves very differently to CQ and it is NOT expected to remain steady at all moments in the recording, particularly if people are not sitting still.</div>
<div></div>
<div>If your sensors remain orange or red, ensure your hair is out of the way, the sensor is touching the scalp and there is enough prime fluid, gel, or saline solution.</div>
<div></div>
<div>You can refer to this link for more information about our CQ and EQ. If you have any additional questions in the meantime, feel free to let me know!</div>Hello Liu. Thank you for your question.
