    Built around the Texas Instruments ADS1299 - a low-noise, 24 bit analog to digital converter for biopotential measurements.
    The Dev Kit is designed to give you low-level access to raw brain signal.
    The sample rate can be set from a high of 16k down to 250 samples per second.
    The raw data can be recorded to file, streamed to foc.us/me or sent to an MQTT server of your choice.

focus EEG Dev Kit streams data via Wi-Fi, has integrated Mic and 8GB of on-board storage.

1. Neuronal Activity

1. Neuronal Activity

The electrodes should be placed under the cap (included). Locate them around the area you want to record. This could be left or right, or a specific region.
foc.us use active electrodes which contain a tiny amplifier. The voltages detected by the electrodes are sent to the EEG amplifier.

2. Collected & Transmitted

2. Collected & Transmitted

The EEG Dev Kit is a miniature DSP computer with an ARM processor, Wi-Fi and internal storage.
The signal from the electrodes is converted from analog to 24bit digital using the Texas Instruments ads1299 chip.
The data can now be stored locally on the device or streamed in realtime over 802.11G Wi-Fi.

3. Cloud Processing

3. Cloud Processing

Included with your Dev Kit is access to foc.us/me - our cloud platform for neuroscience research and education.
Record raw data, apply filters and visuallize power spectral data.
If you prefer to use A.N. Other EEG software solution simply update the MQTT settings and your data will flow there instead. No lock in.

  • Firing Synapses

    Firing Synapses

    Synapses Fire

    An electrical synapse is a conductive link between two neighboring neurons that is formed at a narrow gap between the pre- and postsynaptic neurons (known as a gap junction).
    An action potential triggers the presynaptic neuron to release neurotransmitters.
    These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.


    They're impossible to detect individually, only in aggregate.

  • Open Possibilities

    Open Possibilities

    You are in control and can tweak all of the amplifier settings.
    Chose a sample rate from 250, 500, 1k, 2k, 4k, 8k
    or 16k depending on your needs.

    Higher sample rates generate a larger amount of data,
    so require a blazing-fast network connection to stream.
    Data can be stored locally in international standard EDF+ or BDF+

    All channels can be EEG or two can optionally be EMG / EOG / EKG.

    Total freedom to place the electrodes over any region of your brain.
    You are in control and can tweak all of the amplifier settings.

focus eeg can extend to 40 channels

Need a More Detailed View?

For those of you who know two screens are better than one, you can link EEG Dev Kits together to bring your channel count to 16.

And for those of you who think two is just getting started, why not join 3, 4 or even 5 for up to 40 channels of raw hot data.

Special offer! Order two or more EEG Dev Kits and receive the connecting box and cables free of charge.

 

If you really need more than 40 channels please contact us for a custom connector.

    tES detailed specifications

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

    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 http://foc.us/me/#/device
    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 http://foc.us/me/#/settings and turn on channels
    5) See Readings in multiple places
    a) http://foc.us/me/#/graph-timeseries
    b) http://foc.us/me/#/graph-fft
    c) http://foc.us/me/#/graph-radar
    d) http://foc.us/me/#/graph-gauges

    Recording Session Results: http://foc.us/me/#/sessions
    * 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.

    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.
