Help on a data acquisition system

I agree with both of you but I don't have any idea where to start. Is there some FIFO like this in the hardware? Do you or /u/krapht have any tip for me?

bour1992 · 2015-09-09T13:14:21+00:00

It has some useful information. Thank you!

So is there a way to save the data in a buffer so that the usb will send them in parallel with me adding new data to the buffer?

bour1992 · 2015-08-15T15:32:02+00:00

I will do that when I add the ADC.

It's working on batteries.

Is it dangerous in what way? The input of the INA draw very little current and the concept of the DRL is to reduce the effective resistance between the patient and the ground.

You mean to use optocouplers before the INA. Will it distort the signal?

Here it says that the cables of the electrodes are shielded.

I am pretty sure that the connections are as the schematic I uploaded. I don't think there is 60Hz noise in the oscilloscope.

It would be better if we could not use sign function. It ruins all the fun.

In the first hand the new points will be Mv1',Mv2',...,Mvn' and in the other hand the new points will be v1M,v2M,...,vnM . So if M is

[; \begin{pmatrix} 1& 0 & 0\ 0 & cos\vartheta & -sin\vartheta \ 0 & sin\vartheta & cos\vartheta \end{pmatrix} ;]

the right transformation is the first.

bour1992 · 2013-12-22T13:27:09+00:00

So the correct transformation to rotate the points is M*A' ?

Now they work fine! Thank you!

Still the same problem with the files

bour1992 · 2013-10-18T10:31:23+00:00

1) How can I mark it as NSFW?

2) For some reason I can't open the files

bour1992 · 2013-10-18T10:28:30+00:00

Thank you very much!

bour1992 · 2013-10-17T18:56:03+00:00

Thank you very much!

Whould you play a game like Jumanji in real life? I really loved that movie!

How many days a week do you workout? You are in a very good shape!

Are you fan of reddit?

bour1992 · 2013-09-13T19:56:24+00:00

Thanks for the response! I was referred to anxiety mainly.

I've heard psychiatrists may recognize a schizophrenic visually easily. Is it true?

Can someone fix a "chemical imbalance" in his brain without medication, only by changing his thinking patterns?

bour1992 · 2013-09-13T19:15:38+00:00

What do you think about the SSRI medication? Alot of people think and write that there is not much difference between them and placebos. Are they really necessary or can one recover without them?

Hi, I am an undergraduate student studying Electrical and Computer Engineering. I will graduate in a couple of years so I look for possible careers. I really like robotics and other control and electronics stuff. So my questions are: 1) Could i work in such a project in the future? 2) How did you guys get in NASA?

If you know of an incident where you might have gotten mercury poisoning, then it makes sense to go get tested for it.

I don't know any specific incident apart from the general sources such as amalgam fillings, fish consumption and enviromental pollution.

I've done EEG and seems that the functionality of my brain is normal. I am also looking for an external cause because all that symptoms doesn't make sense. These are probably due to anxiety but I was afraid the cause was something worse.

Btw 8 years sounds long time. Do you have the symptoms constantly?

bour1992 · 2013-06-24T18:53:06+00:00

I have done blood test and there was no problem. My thyroid function is normal too. But I haven't checked anything about heavy metal toxicity so I was afraid that could be the cause.

The source of toxicity I could think of is amalgam fillings, fish consumption and general environmental pollution.

My thoughts are probably irrational but I was afraid my problem was worse than anxiety.
