@omkolhe No idea. But curious what you're using it for?
@omkolhe short of remaking the LCD electronics circuit yourself, I dont think you can change the refresh rate. Also the shift registers used might be the limiting factor, in which case theres nothing you can do to the screen for a greater rate. You might find higher refresh rate screens online though
how can i use accelerometer readings to detect a dynamic motion, like circular motion
@mohit-madan you would be better off using gyro sensors for rotation/circular motion
and for detecting revolution
@udiboy1209 and for detecting revolution??

@TheShadow29 openmp you say! You've used it? I'll surely have a look!
@PrieureDeSion I havent used openmp
Does anyone have an avr chip ??
Suggestion for plotting data real time?
I mean software or how to?
U can use python using matplotlib, but it is slow. I did and can send u the code if you wish. Probably some other language may be faster
@PrieureDeSion one word of warning, openmp with mac is pure hell

@riddhishb noted! :wink:
When we say that a mono sound is splitted into stereo (left and right channels) is it just as simple as sending half the power to my left ear piece and half to my right ear piece to create stereo effect or does something more takes place? Curious.
I don't think so @parthk-git 'coz you don't normally get the same sound in both the ear pieces. Like, both the left and right ear-piece compliment each other, but do not give the same sound. Correct me if I'm wrong.
Yes, you are right. I forgot about that fact. So, I do know in audio mixing the music artist separates left and right channels. Then how does our headphones know how to separate the sound? Sound specialists?
@parthk-git "Splitting a mono sound into stereo" where is that done? Most music players give a stereo output as it is.
^And, AFAIK, stereo sound is recorded using two separate microphones or something like that, not sure though.
Well, i feel when the sound is recorded, there itself the sound engineer does audio mixing and splits the sound into 2 channels.....
Just like an Image having RGB channels from the start...
Okay... Those who have worked with BT (HC-05) I have this doubt. We have set the protocol to 8,N,1 with baudrate 9600, that is, 9600 bauds/sec where each baud has 1 start and 1 stop bit and 8 data bits. So, while connecting HC-05 to fpga board and transferring info, do we have to provide only the 8 bits of data which we are sending (and HC-05 itself adds the start n stop bits) or do we have to provide the start and stop bits also? Or something else altogether :P?
The hc05 adds them by itself , only the data you want to send should be entered into the UDR
The USART looks into all the transmission specifics. Just enter the data as Sreekar said.
So, I should be entering bits at a rate of 9600x8 bits/sec right? and not 9600x10?
Hello People, Electronics club IITB proudly presents its first ever GD on “Memristors” ! So what exactly are Memristors? Memristors are, in simple words, Resistances with memory - Devices whose resistance depends on the current that had flown through it ! It's believed that memristors have the capability to change the whole computer architecture we use now and will bring a revolution in how we use our computers and other electronics devices. How? Well, that's what the GD is all about :D So let's explore this exciting world of memristors on 29/07, Friday, 9 pm in Yoga room ,old SAC. PREREQUISITES :- Need to know basic Electromagnetism (PH-108) and basic Analog circuits for easy understanding. P.S. Lets learn something new going on in the field of Electronics in today's world, something more than our classroom studies.
Do RFID tags not work properly when a few of them are at the same place? Like, not very far away (say in a room)? (It's called Tag collision or something)
If the tags are passive(i.e. One without battery) the ability to detect multiple tags depend upon the power of the device and also something called anti-collision algorithm is used.
@atish-aloor may tell you better
Nfc chips implement anticollision usually. The standard ones can detect 2-4 cards simultaneously. This is within the detection range. Outside the range (which is what you seem to be asking about) it shouldn't matter how many cards are present.
The detection range is normally around 4 inches for passive tags
The range depends upon the the power of the detector and also on the what frequency you are using for communication. Standard being 125kHz 13.56kHz ~900MHz
Hi, processor based project I have Raspberry pi3
Is this still active?
Yup thats the plan
Can anyone help with PPG?
You need to ask specific questions @shagunkapur :)
is line follower is event in IIT's
