@wjcroft Would the Bluetooth dongle at the end of my repeater/USB extension cable attached to the USB port of my laptop then be inserted into its own housing provided on the Cyton (within the cardboard enclosure) or would it be taped separately to t…
-
@wjcroft Thanks. I did not actually mention a plastic enclosure, but will carefully consider the suggestions which you made. One of these was:- "Use some type of small clip to fasten it to the shirt of the subject." Would the clip not be a cumber…

I am in process of climbing aboard the extension cable idea but the rest of this discussion is beyond my technical grasp and experience.

@wjcroft Firstly, "The spikey electrodes are particularly difficult to insert ...:" This is obviously quoted from OpenBCI documentation on the headband kit. Could you tell me whether the newly introduced Dryodes (https://shop.openbci.com/products/id…

@wjcroft Having looked at http://openbci.com/forum/index.php?p=/discussion/176/placing-electrode-sensors-on-the-scalp and https://bio-medical.com/brainet-placement-caps.html the following question arises:- Can placement caps be used i…

@wjcroft What I am hoping to detect with my EEG hospital study will have to wait until I can confirm my expected findings which, when published, will need to be replicated by others to prove my hypotheses.
-
@wjcroft Are there ways, on OpenBCI, of completely ridding EEG data/signals recorded on micro SD cards of unwanted noise?
-
@wjcroft @Frederik_D_Weber Thanks Vielen Dank. However, without the OpenBCI Headband Kit or Ultracortex Mark IV EEG Headset, it would take practice to get the positioning of the electrodes correct. How does a novice achieve this (International 10-20…

@wjcroft Hi. What is the maximum effective Bluetooth range of the Cyton+Daisy board and OpenBCI dongle?
-
@wjcroft In relation to the above discussion, you may be interested in this battery tester with an adjustable low voltage alarm: https://www.amazon.com/LiPo-Battery-Checker-Monitor-Indicator/dp/B07BQWSXC4
-
@wjcroft Yes, I would be measuring EEG both in the state of wakefulness and sleep. The electrodes in the following link (https://bio-medical.com/disposable-webbs-silver-silver-chloride-electrodes-10-pack.html) seem appropriate as the Grass paste app…

@wjcroft Thanks for the update with the following link: https://www.natusneurostore.com/p-1559-ec3-grass-conductive-adhesive-gel-176-oz-50-g-12pkg.aspx. You write: "Generally the dry silver chloride EEG electrodes used in that kit (and the Ultracort…

@wjcroft. Thanks for your dedication.

Interesting stuff for anyone wishing to develop software for neurofeedback training.

@wjcroft Hi again! Your reality check above for the 6600 mAh Adafruit battery indicated a battery life of 5.5 days, at least in theory. I am currently using a Nokia 2.1 mobile phone with a 4000 mAh battery. After fully charging the battery, I can…
-
wjcroft Hi. How does one know that the USB super flat cable and repeater USB extension cable ordered for will fit snugly onto the OpenBCI Dongle? There happen to be many sizes and ypes of USB repeater and super flat cables, some with micro B male he…
-
@wjcroft. Thanks once more. However, I would prefer to be over-powered with the 6600mAh battery considering that the Cyton Daisy board would have to communicate for 9 to 12 hours by Bluetooth, on a single charge of the battery, with a dongle at the …
-
@wjcroft Thanks for the clarification. For the avoidance of doubt, it seems clear from your answer to my enquiry that the JST-PH Battery Extension Cable - 500mm can be added without the risk of distorting EEG streaming and recording; and, that the A…
-
@wjcroft Hi. Here's a link of a video about how potentially dangerous LiPo batteries are:- It raises again the related issue of having a high capacity Lithium ion battery close to patients in a hospital ward while their EEG data are being streame…
-
Thanks again. I am much obliged.
-
@wjcroft Thanks for your original reply and updates. I had in fact come across the difference in current/wattage nomenclature in the following excerpt from a highly relevant review (https://reactual.com/portable-electronics/batteries-portable-electr…
-
@wjcroft Thanks. I will have a look at the tutorial.
-
@wjcroft Thanks again, William. Your reply is useful as before. From the point of view of conserving the Cyton +Daisy Board battery power, it would make sense to use a USB cable for transmission of data from it to my computer. From my experience wit…
-
@wjcroft Thanks, William. I have had a look at the USB extension cables:- https://www.vpi.us/usb-active-extension-cables/usb2-extender-cable-1572. It just occurred to me to ask whether the EEG signals from the OpenBCI headband and Cyton +Daisy…
-
@wjcroft Thanks, William, for your kind and useful suggestions. This gives me a confidence boost in my quest to acquire the OpenBCI apparatus to carry out my experiments and test my hypotheses.
-
@wjcroft Thanks, William. The following seems to be the most practicable part of your suggestion:- 'Perhaps the simplest solution is to just use a USB extension cable. Possible even routed through existing wiring conducts / pathways that are a…
-
@wjcroft Yes, I am asking about the Cyton +Daisy board. My overriding concern is that if I purchased just the Cyton +Daisy without the Wifi Shield, it would not serve to transmit EEG data from an OpenBCI headband (with 16 channels) on a patient's he…
