@allenineYou don't need to re-program the Ganglion to do alpha detection. I have updated Chips code here https://github.com/biomurph/OpenBCI_AlphaDetector This will only run on Processing 2.2.1, and I can't make any guarantees that it will actual…

The accelerometer is not enabled by default. You need to send the Ganglion the accelerometer enable command.
-
@tricentThe maxed out accelerometer is disconcerting. I would expect that if the inputs are not connected to anything that you would get something undesireable, but the accelerometer values should never do that. Please email contact-at-openbci-…

@wliao229 The Ganglion is re-programmable over the air. I am finishing a tutorial on that now.
-
The impedance test is measuring between the '+' inputs only and the 'D_G'. If you put the + and - together, it will not make a difference.

See my post herehttp://openbci.com/forum/index.php?p=/discussion/956/is-a-working-sd-card-still-on-the-ganglion-roadmap#latest

You should not need to look for the Ganglion by using the driver, or other tool. The OpenBCI GUI should connect to the CSR 4.0 dongle straight away, and give you a list of Ganglions in the area that you can connect to.
-
@hmbtecAre you saying that your computer can see the ganglion and then it connects to it? When the LED stops blinking, that means the Ganglion is connected. If your computer is connected to the Simblee (Ganglion) then the GUI will not see it. You ne…

@amiyahave you resolved this issue? for doing ECG and EMG, the on-board dip-switches should be in the UP position. With the switch lever alighned with the white markings on the switch.
-
It's not possible to 'plug-n-play' with the current version of the GUI. There is a 'middleware' piece, called the Ganglion Hub, that is doing the work to connect and communicate to the Ganglion. Right now, the GUI needs to 'release' the Ganglion, an…

@ocanathThe D_G pin on the Ganglion is connected to the output of a follower circuit that outputs 1.5V. This is the '0V' in our circuit. In the design phase we never saw any better CMRR between the D_G or a DRL/RLD type circuit with inverted common …

@wjcroft is right, you need a legit CSR 4.0 dongle. Beware that there are some out there that are copycats.the ones that adafruit sells are g to g.
-
The Ganglion will support and will record data to a microSD card. You can follow the same general guidelines herehttp://docs.openbci.com/Tutorials/09-Using_SD_Card_with_OpenBCI to make sure you have the right quality SD card and format it correctl…

The next release of the GUI will support Pulse Sensor.And yes, the Ganglion board will also support Pulse Sensor. We are currently putting together the docs and examples for uploading code to the Ganglion.
-
Your's is an interesting case, Zigzagzen.Does using the CSR 4.0 Dongle work on Windows VM?
-
Are you still having issues connecting with the Ganglion?If so, can you try a different computer or update your OS? There may be issues with BLE and El Capitan.
-
This problem occurs if you are not set up to run apps from 'Anywhere'. This is easy to do in settings on OS prior to Sierra, but in Sierra you need to do some special things. Go here to unlock the 'Anywhere' option on Sierra. http://docs.openb…

I ran a quick test connecting Pulse Sensor to the Ganglion front end input, and it doesn't work because of two things. The Pulse Sensor outputs a very large voltage swing, and the Ganglion is trying to amplify tiny signals. Also, the compression …

Simblee is not readily discoverable with BLE on a computer or phone/tablet. On your android phone, you can use nRF toolkit https://www.nordicsemi.com/eng/Products/Nordic-mobile-Apps/nRF-Toolbox-App This tool will be able to find and connect to t…
-
@wliao229This seems like it ought to work. I will do a test here in the lab today. Here's some quick thoughts on your setup. First, you are measuring on pins 1+ and 3+, but both 1- and 3- are not connected to anything. These are differential i…

dfletch42, Yikes! I hope you're not connecting to and plugging yourself into the wall outlet through your USB connection! This is something very serious that you're doing, and I want you to know that it is not at all recommended in any way. Also…
-
@allenineProgramming the Ganglion will use an OTA (Over The Air) toolchain. It starts with the Arduino IDE, and moves through some nRF tools from Nordic Semiconductor. You will use your phone to do the OTA process. Tutorial is forthcoming. Than…
-
Hey, this is great news! We have a couple of Win7 laptops here in the lab, and I will run through the steps that you are outlining here. I did a quick look-see, and found a page with the CSR Harmony Wireless Software Stack available for download. …

re-flashing the Dongle firmware would not necessarily solve the problem. There are two systems on the Dongle. One is the FTDI IC, which provides the USB to Serial connection for the RFduino, and the other is the RFduino, which does not have any rela…

The tutorial for uploading code to the Cyton (formerly 32bit) board has been updated. http://docs.openbci.com/Hardware/05-Cyton_Board_Programming_Tutorial This issue came from our uploading the 'BasicBoard' sketch instead of the 'DefaultBoard…

Hi Matt, The short answer is that we don't have certifications for the device. Please review the disclaimer at the bottom of the product page for more specific information.
-
What is your setup? Please describe the montage you are using so that we can help trobleshoot.
-
I don't see how sharing the SPI bus with the ADS1299 is causing your problem. When we made the 8bit board with the ATmega328, we had all of the parts on the board when we burned the Arduino bootloader (which uses the SPI bus).Perhaps the level shift…

@PaskiWe are going to send out an update/newsletter this week with the details. Basically the Mark IV and Ganglion will be delivered in October. We had some issues with the Bluetooth throughput that have been resolved, and the injection molding of …

The Ganglion will have 4 channels of 24bit data sampled at 256Hz.We are using the MCP3912 ADC for digitizing the signal, and an Instrumentation Amp in front of that to provide the high impedance and low noise. More details to be delivered when w…
