Hey! This might be a silly question but I looked at the schematic that’s uploaded on your GitHub for muscle bioamp patchy and I can understand that inaIN+ and inaIN- refer to the inputs from the detection electrodes and ampRef the input from the reference electrode. However, at the power supply part ampRef is the output of an amplifier which means it has a set value, how can ampRef be both the electrode input and amplifier output?

[@UpsideDownLabs]

Hey, that electrode is actually vcc/2 voltage output that sets a base voltage for the analog circuit and the human body. It's usually called bias electrode or ground for these type of analog circuits and acts similar to how digital ground works for your digital circuits.

@@UpsideDownLabs Thank you very much!!

[@elenimoniaki7170]

@@UpsideDownLabs Also sorry for asking again but I’m using arduino zero for measurements which has 3.3V tolerant I/O pins is it alright if I use a voltage divider with a 1kOhm and 2kOhm resistors to step down the analog signal voltage before feeding it to the adc? Would the voltage divider reduce the accuracy of the samples significantly and are those values good enough or should I use 10kOhm and 20 kOhm for example?

Can we control car in Forward-Backward-Left-Right direction?

[@UpsideDownLabs]

yes that can be possible but in that scenario you will have to take a different trigger to control left and right directions.

[@jaineelchhatraliya7186]

@@UpsideDownLabs I am very exited to do Neuroscience projects specially using EEG signals. So i really want to add this feature in the project(Left-Right-Forward-Backward direction). So will you just guide me? So It will be very helpful to me!❤ B. Tech ICT, Marwadi University Greetings from Rajkot🤝

[@UpsideDownLabs]

It will be better if you start with simple projects, learn along the way and then move towards complex projects. Particularly for EEG you can try the following projects one by one: 1. Recording EEG from prefrontal cortex: www.instructables.com/Recording-EEG-From-Pre-Frontal-Cortex-of-Brain-Usi/ 2. Recording EEG from visual cortex: www.instructables.com/Recording-EEG-From-Visual-Cortex-of-Brain-Using-Bi/ 3. Playing video games using brainwaves: www.instructables.com/Controlling-Video-Game-Using-Brainwaves-EEG/ Once you are familiar with these projects then you can try to add more features into them. Another way would be to start with the biopotential signals that are comparatively easy to deal with like controlling video games using EMG or EOG and then move towards doing projects with EEG. Anyway we are coming to Marwadi University for a 1 day workshop as soon as the flood situation gets better. So we can probably meet there as well to have more discussion on it. You can ping us by emailing on [e-mail] and we will keep in touch.

HI, I have 5 bioamp exg pill, I need to know how much is the sampling rate of the module "bioamp exg pill" when we talk about EEG and why it varies in terms of EEG, EMG and ECG? PLSSSSSSSSS GREETINGS FROM BOLIVIA!!!

[@UpsideDownLabs]

Hi, The sampling rate depends on the microcontroller development board you are using. For example, the sampling rate for Arduino Uno R3 is 250 by default but it can be changed in the code as well.

[@samkumar6378]

Can we control this same game by voice commands Such as : Fast Slow stop Break

[@Runstargaming]

Can i use Arduino uno

[@UpsideDownLabs]

Yes definitely. Even we have used Arduino Uno R3.

[@asadmahmood6724]

I tired this, but the game does not really gives good accuracy with the model , even if i am fully focused it stops the car " I fully understand that this is not a 100% Working project , i just wanted to make sure that its the model or Me, is there any chance i am doing something wrong while recording, Emotions. I can show you my result what i am having. For better understanding . Reply me when possible, i myself will delete the comment. I also understand this comment is bad, Sorry

[@UpsideDownLabs]

Hey Asad, We totally understand and there is no need to delete this comment :) Yes the accuracy is not that great as it totally depends on the sample EEG data used to train the model. This was a college project by Umang which he made in 4th year of this engineering and with this video we wanted to showcase the possibilities of using our brainwaves to control devices (in this video controlling a car in the laptop). You need to make sure of the following in order to record good quality EEG signals which will further be used to train model. 1. The sample data provided is very limited as Umang only recorded his data to train the model so it is always better to record your EEG data first and then train the model accordingly 2. Sit 5 meters away from any AC appliances to minimize 50Hz noise interference in the signals 3. Only use laptop and do not plug your charger to the laptop while recoding the EEG signals 4. Use skin preparation gel to clean the skin surface before placing the electrodes to clean the dirt from skin wipe with it either with an alcohol swab or wet wipes. We have already started working on another game where you can control a ball in the laptop by focusing on it. The best part is that it is just a python script and there is not need to train the model in order to start playing the game. The complete video will be out soon.

@@UpsideDownLabs That's Sound Awesome.Waiting For your next video. I will make second point you mentioned, i might have a little 50hz interference.

make a project to write in notepad please

We did not get you. Can you please explain a little bit more about it?

[@growwithanshuman]

[@UpsideDownLabs]

That would not be possible to with DIY Neuroscience Kit. The main aim of this kit is to provide an affordable tool to a user to get them started so that they can explore the field of neuroscience. What you are talking about is a "thought to text experiment". For that you need a highly dense multi channel EEG acquisition system and on top of that you need very efficient AI models. We recommend you to start with simple projects, learn along the way and then move towards complex projects. Particularly for EEG you can try the following projects one by one: 1. Recording EEG from prefrontal cortex: www.instructables.com/Recording-EEG-From-Pre-Frontal-Cortex-of-Brain-Usi/ 2.
