Thanks William! I did the same google search and realized nodeJS + Raspbian is a great combo. I guess I was just confirming that the dongle in the USB port would be seen the same way... which you seem to have confirmed as well! Time to build …

Got it... Thanks!
-
agreed, I'm picking up the 1000 and the 500mah... use one, charge the other thanks again!
-
ROGER THAT! thanks!

Makes sense! A few more noob questions: When chosing a 100mAh vs. 500 mAh pack, how do I know what is needed? I need to basically present a 30 minute demo, but I would ideally like at least a few hours out of a pack. How can I gauge capacity…

Thanks! I saw these, but got lost in all the options. Do I just need a 6V source? if I find any 6V battery will that power my cyton? do you recommend any specific one? -Rishi

Thanks William - I had reached out to him earlier, just hoping to get a reply back soon Thank you for all your guidance!! -Rishi

I think the nodeJS libraries are masking what the serial data coming in looks like, and how it maps to the Cyton object in the code. I instantiate the Cyton, then once I start the stream, I get access to the data elements in the sample object. Th…

That's my nodeJS code where I'm listening to the data stream and sending JSON messages to my analytics tools. I don't see an example of nodeJS where I can pull the auxData, but I guess it to be "sample.auxData[0-2]"? ps - what did you mean tha…

OK, this will take me a bit to decipher, but I'm mounting ECG to the chest and keeping my bicep points. The part about the overlapping circuits makes perfect sense. I'll also look at the SDK on how to disconnect the SRB and Bias busses.... will e…

I see the part of the tutorial that I've missed - I'll work through that today. Just to validate tho, these are changes that are for the GUI right? the "raw" signals coming through aren't processed here. I'm getting my data primarily through the…

ok so i wired it all up... two leads on one bicep + wrist placement for ECG (for now) I see the ECG graph on both channels inthe UI, and when i flex my bicep, both graphs show muscle activity. Is that normal just because of the way the UI wor…
-
Wow.. this is quite eye opening. I cannot thank you enough!! So if I got this right, let's say I set this up: 1 EMG lead from ground to somewhere on the body 2 EMG leads from top and bottom N1P to each wrist 2 EMG leads from top and bottom N2P…

oh, that's interesting.. i don't need the myoware at all? I bought these from OpenBCI.com: EMG/ECG Snap Electrode Cables https://shop.openbci.com/collections/frontpage/products/emg-ecg-snap-electrode-cables?variant=32372786958 let's say I hav…

I ran out of things to keep adding to add up to 8 for my hyperbolic example... but yes, the ECG gives me most of what I need. At this point, I just have an arduino for the Oximeter, but all else is coming from the Cyton + Myowares. BTW - I kno…
-
Roger that and agreed... thank you!!!!!
-
Just to make sure, based on the fact that there are 8 channels, I can have conceptually 8 muscle signals coming through? or 8 of any type of sensor that's supported by cyton? If I wanted 6 muscle sensors + 1 ECG + 1 pulse sensor, that's just a ma…
-
Yup, I was looking at those. Ideally I wanted as many signals coming through the Cyton as possible as I have the nodeJS code working there already, but not a big deal. Looks like my ECG, EMG comes through Cyton and Oximetry comes through Arduino.…
-
Thanks William! I found the port after realizing that I needed to start the OpenBCU_GUI with the sudo command. For some reason that worked perfectly.
-
William, Thanks for the replies! The wire length one makes perfect sense, I'll build accordingly. As for the Bias, i guess the bias is considered a type of a "ground"? I have the cyton working with the myoware perfectly - I guess my next …
-
Is there a limit to the dupont cable/wire length that I can use when connecting the little sticker pad to the board or the sensor board to the cyton? I wanted to wire my bicep to the myoware board and then connect that to the cyton and that might …
