It took me 15 minutes to read one page of my introduction to circuits book. It took me 8 hours to read 30 pages and I remember only about 10% of what I read. (meaning I can't really summarize to someone else what I learned after reading). It takes me at least 3 readings to grasp 50% of the...

ability to feel electrical/magnetic fields? are there anyone here who has worked in a manufactoring environment? I have found that when stepping out into areas with higher amplitude electrical fields, I get a strange feel where my chest feels heavy and breathing becomes more difficult. Any...

I know the peripheral nervous system is all connected at the spinal column. If spinal EEG can be conducted, could it be possible to observe movement of limbs on a EEG chart?

I want to build a EEG and the site tells me to buy a PCB from some manufacturer. Will my product have competent performance if built with breadboard? What is so special about PCB？

I ordered some EEG electrodes online and I am planning on building a EEG myself to do lots of ideas i have in the meantime before the electrodes arrive, i want something to substitute for eeg electrodes. I was wondering about some substitutes and what exactly is special about eeg electrodes.

I never understood the concept of prisons for rapists, murders, etc... Isn't it much cheaper to just execute them? Someone willing to rape or commit murder won't be contributing to society anyways. Whats the point of rehabilitation?

Its not always possible to have smaller classes though... if EEG technology ever becomes cheap enough that every kid in a class of 50 to 100 can have one, learning can become much more efficient. In large lecture hall situations, many kids just either sleep or play on their cellphone. There...

Thanks! that helped alot

Now I'm sure many of you have wished that you were better able to pay attention in the classroom. Well, what if the teacher gained the ability to monitor the attentiveness of everyone in the classroom? how can this be done? simple, attach a few EEG electrodes to monitor the activity in a...

I drew a circuit using paint for this function. I was wondering what kind of individual comparator should I use to save the most power. Also, what are some less noob ways of going about this? sorry if stupid question. I am an undergrad

here is the composition of seawater according to wikipedia: Component Concentration (mol/kg) H2O 53.6 Cl− 0.546 Na+ 0.469 Mg2+ 0.0528 SO2− 4 0.0282 Ca2+ 0.0103 K+ 0.0102 CT 0.00206 Br− 0.000844 BT 0.000416 Sr2+ 0.000091 F− 0.000068 from inspection, it can be seen that seawater has...

Hi everyone: Since there are many ions in ocean water, and these ions are carried by ocean currents, and they are moving through the Earth's magnetic field, by the electromagnetic induction laws, wouldn't there be a induced electric field in the ocean? if i want to detect this electric field...

I don't think so. I just need the devices to work properly

Hi: Im currently in my last year in a EE program and I am helping a professor with research My task is connecting a NRF905 transceiver with a 10bit ADC and relaying this information wirelessly. The transceiver will receive the information from the ADC in SPI format. Can someone give me some...

if we are given a polynomial s^6+as^5+bs^4+cs^3+ds^2+es+k (if a,b,c,d are known) what is a clever method to solving for the value k if we are given the following: the above polynomial is equal to the following(zeta is given as some constant, say 1 for simplicity)...
