    Hey, @jddeep can you please check this fossasia/neurolab-android#629 .I have worked on an animation for the play/pause button and will be able to adjust it properly once the broken meditation player is fixed with this PR.

    Hi there are some issues already open related to functionality, most of which are straight forward and easy fixes. You can go ahead with those or open new required issues. Thanks

    Dear @/all today we received the very sad news that our dear friend @iamareebjamal has passed away. We are very disturbed by Areebs sudden death. In the last few years Areeb became like the beating heart of FOSSASIA. He kept everything running and developed all kinds of amazing services and tools. We would not be where we are today without him.

    He was an amazing person and brilliant developer. I worked and communicated with Areeb nearly every day and I also had the chance to meet him in person in India. The last time we got together in Delhi when we organized the OpenTechSummit mini event in Delhi.

    He loved to share his knowledge with anyone and expected even nothing in return. He was a modest and humble person. He deserved to live a long life and make his dreams come true. Areeb had big plans and we had discussed to get him to Singapore to run the FOSSASIA development from there. An amazing future was in front of him.

    We will be sharing more about Areeb on our channels. Please post your thoughts and experiences with Areeb on the web and provide support to each other in these difficulties times. Be safe and healthy!

    You can find out a bit more about Areeb on a video we put together here https://www.youtube.com/watch?v=XbFCBp-LTXc

    Hi, I've been reading the schematic for a while, but the schematic library seems not included in the repository https://github.com/fossasia/neurolab-hardware.git here.
    Does any have the library?
    Mario Behling
    @mariobehling
    @CloudyPadmal Do you know about the schematic lib?
    RafaelLeeImg
    @RafaelLeeImg

    I mean the schematic symbol library is empty

    $ cat schematics/sym-lib-table
    (sym_lib_table
    (lib (name neurolab-rescue)(type Legacy)(uri ${KIPRJMOD}/neurolab-rescue.lib)(options "")(descr ""))
    (lib (name neuro)(type Legacy)(uri ${KIPRJMOD}/neuro.lib)(options "")(descr ""))
    )

    @CloudyPadmal
    Hi @mariobehling it looks a bit more complicated than I previously analysed.. More of a rework to update the schematics referring to the pdf https://github.com/fossasia/neurolab-hardware/blob/master/docs/schematics/neurolab.pdf

    This circuit is really simple. TL074 is a cheap quad-amplifier with J-FET input. It's a analog front-end. TL074 is easy to find. Then we only need to sample the analog signal.

    I'd like to make several PCB and try out.

    It's a simplified version of 2-Op Amp Instrumentation Amplifier.

    I've sent the gerber of bioamp-exg-pill to manufacturer and bought some tl074.

    Hey, I am the creator of BioAmp EXG Pill. Let me know if you guys need any help :)

    Also, KiCAD files for v0.9 have been pushed.

    Hi @lorforlinux we are currently looking at options to integrate your project with Neurolab. @RafaelLeeImg Wanna share a few details?
    Deepak Khatri
    @lorforlinux
    Hey @mariobehling, do share the details for your requirement.
    I have pushed v1.0 alpha files and I will be creating more example projects/demos very soon :)

    @RafaelLeeImg
    Wow, there are something I want to ask. Neuron signals are about 70mV (out side the cell membrane), but I don't know what's the voltage range of the signal on people's skin?
    Deepak Khatri
    @lorforlinux
    @RafaelLeeImg It depends on the placement of the electrodes on the body.
    It's usually <1mv with electrodes placed close to the head.
