    Hi,
    I wasn't able to give an immediate response to the new posts; I'm preoccupied with my college classes, and this project is more or less in the backburner.

    Thanks for the detailed instructions, @Gordon. I currently do not have soldering tools to remove and attach electronics, but I could get them a few weeks from now. This is going to be my first time modifying PCB boards, although I have some experience in soldering and the proper equipment to perform it.

    @kri100s, the links you have provided seem to detail a manufacturer's component. I could sample it and design a PCB to mount it to the analog pins, but I'm not sure what other components it would need (it has 56 pins which is a little intimidating). I don't have too much experience with electronics and I'm pretty terrible at reading PCB schematics and block diagrams; in my spare time, I'll try to improve reading these diagrams.

    Eventually, I want to create custom straps with embedded electrodes for the sensor. If I go the extra mile, I could also add a new HRM. For now, I'm seeing if I can modify the watch to accommodate just the skin-conductance sensor.

    @Gene, Morse code messages sound like an interesting idea.
    I was actually thinking of using Morse code as a means to input text on the device, given the limited set of buttons that it has. However, I can't imagine myself decoding Morse code that easily, let alone inputting text with it. It's probably worth a try, regardless.
    Edit: Excuse me if this is a dumb question in regards to capability but, is it possible to play sounds from the watch using a Bluetooth audio device?

    Hi all,
    I bought the Bangle.js watch to experiment with its sensors and create a program for behavior awareness and intervention (I am an individual struggling with anxiety and anger issues).
    The program that I have in mind will function as a stress indicator; this program will use the correlation of a certain sensor readout to stress and will display an alert if the sensor's value goes beyond a predefined threshold.
    Because I find the heart rate sensor to be too flimsy for accurate HR measurements, I want to use a skin conductance sensor instead. However, I have no idea where to start, regarding watch modifications and sensor placement. One issue is finding the connections on the Bangle.js' board that I can use, and another would be creating and connecting the circuitry. I also know well that passing a current through skin can cause electrical burns with prolonged usage--I want to prevent this while still being to wear the watch on a daily basis and without any inconvenient maintenance/precautionary procedures.
    Given these issues, does anyone have any ideas how I should approach them?
