Did you find a fully waterproof button?
I plan to use normal momentary switches and cover them in silicone. My design has 2mm deep cavities which should make for a few tenths of silicone over the button. That will hopefully be flexible enough to use the button and still hold up to daily use.
useable without a button
I had tried this by listening to the
accelevents and calling everything in the pin watches array for the button. Worked halfway decent but I did not want to modify the bootloader to make it work there as well so I decided to keep the button.Did you already dissassemble a bangle js 2?
Multiple Bangles, some of them multiple times :) My current way of choice for warming the Bangle up is a pot with a bit of simmering water and a flat top. My cookware has flat glass lids which get close to 100° with the steam from the simmering water. I just place the Bangle display down on the glass until it is hot enough. I have a heat gun with temperature settings but that has not worked as well for me.
Is there a reason you decided to use usb charging?
Multiple:
- More sturdy connection for charging in a bag
- One less cable to forget while packing for a trip
- Corrosion of the contact pads
- No idea how to get push-pins and magnets etc. aligned properly and waterproof :)
did you consider trying to make an outer case for the Bangle to waterproof it?
Maybe there is ABS as a very thin sheet or even film which could be "glued" over the button with acetone?

@halemmerich that's a great project!
Maybe you can help me with your experiences with my own project. I am working on a project to make the bangle js 2 waterproof.
I decided to go buttonless because I fear the button is the main issue and many smart bands use the same approach. And it can easily be done by modifying the existing backcover 3D design. I already modified it and removed the button and barometer hole. Did you find a fully waterproof button?
Currently I am working on the software part to make the bangle js 2 and the existing apps useable without a button by sending "virtual" button events based on accelerometer double taps. It is partly working and looks promising.
Did you already dissassemble a bangle js 2? I only tried it with a magic 3 and it was easy with a fan but later I broke the display cable.
Is there a reason you decided to use usb charging? I hoped that the charging pins are easy and waterproof to glue and can be used for swd without opening the watch. Any idea where I can buy charging pins because I don't think I get them removed from the original bangle?
Thank you!
