    tES detailed specifications

    Don´t see the detailed specifications for each of the 8 channels parallel tES(tDCS, tACS, TPCS, tRNS, tPNS & so-tDCS).

  2. Steven

    No documentation included in kit. I am willing to help document.

    Can you please help answer the below?

    Open Questions:
    Is the setup video available as mentioned in the newsletter?
    Is it possible to configure the transcranial Electrical Stimulator?
    How do you reproduce the Lucid dream experiment?

    Helpful Tidbits:

    Accounts: The store account is different from the EEG Dev kit account

    Setting up Wifi – Make sure to add all the Wifi Connections upfront when you connect to the “EEG-DK” hotspot from your phone or laptop. You can override it later but it can be a pain.

    Best way to Test Wifi:
    1) Visit
    2) Look at Connected – Red Off / Green On
    3) Turn your EEG Dev Kit On – Red should go to Green and a message saying “Device is On” should pop up at the bottom of the page
    4) If your device was on, you can turn it off and should see message “Device turned off” and Green Should go to Red

    Updating FIrmware: To update your device – unplug it and turn off, re-insert power adapter, and wait. If your device can connect to Wifi it will grab the latest firmware and update itself. You will see a white flashing light.

    How Test:
    1) Unplug power – Reduces Noise
    2) Plug in one Dual Active Dry Electrode Pairs in the [1][2] slot. Optional also do [3][4], [5][6], [7][8]
    3) Power on
    4) Visit and turn on channels
    5) See Readings in multiple places

    Recording Session Results:
    * After recording, it takes a while for them to be processed.

    not there yet

    This device is missing a bunch of functionality right now but the core shows great promise. Will update review when appropriate.

  4. clamport

    Good, but a few issues

    Good product and I can definitely see the future of it, but a couple of issues.

    1) Prior to charging I could use the battery. After charging, the unit will not power on without the charger attached.
    2) How do you get the leads attached to the headset so they will stay?
    3) No instructions provided, nor are there any available online
    4) The menu on the app nor the page works on chrome, it’s cut off about 1/7th of the full menu so you can’t read the options.

    Again, great product but needs some work to become mainstream.

  5. sunnyD


    Good: easy setup, wifi, EDF recordings, ADC quality

    Bad: hat, electrode holding, documentation

  6. dr p

    great value eeg

    This device is excellent value for money – it gives readings comparable to eeg devices 10x the price!

  7. dr_k

    excited for fnirs!

    The data quality from this device is extremely high, way higher than I expected.
    Importing EDF into matlab is simple and powerful.
    Very excited to try the fnirs sensor.
