    Btw, started working on a simple graphing solution like in the Micro:bit editor. Smoothie Charts, used by Micro:bit editor looks pretty nice for simple real-time graphing: http://smoothiecharts.org (MIT license)

    Input lines either JSON, for example {foo: 10, bar:15}, or what the Micro:bit does: x:42. Altho thinking about a prefix to either ignore certain lines, or process only certain lines. Could be a config options.
    One graph per data stream, because Smoothie Charts doesn't support labels / legends, and your values can be vastly different.

    A small difference compared to Micro:bit: I would open a popup, so you can resize or place the graphs where you want.

    Ideas, suggestions?

    Nice!
    What about optionally saving to localStorage, so you don't lose data if you accidentally close the tab, forget it, etc?

    Hey, while you are there, what about adding "simple" graph like one in MakeCode or Arduino Ide? :)

    Oh, the Q3 will be Bangle V2?

    The Bangle is an existing smartwatch running custom firmware. DT No1 F18, looks like it's missing now from the manufacturer's site, but for example it's here too: https://www.smartwatchspecifications.com­/Products/no-1-f18-sports-smartwatch/ the images show the stock firmware.

    Updated to latest, app launcher works, but found and interesting glitch: just tried opening an app (GPS info for no particular reason), and after exited by long pressing BTN3, the screen was shifted half screen up:
    https://drive.google.com/file/d/1hNbCu-m­4OEqzd7PO-fJXu96iUlYn2H4o/view

    It's working, I can go into the menu, I can go up-down, but the screen is still shifted:
    https://drive.google.com/file/d/1hK8wItl­Zx4tMQ_6a93I2BbeprTHgAXgQ/view

    And can't restore it. After launching "About", the GPS info app still seems to overlay over it: https://drive.google.com/file/d/1he66Iaa­WtNG4l1fLN4xxhpH4manAsIUs/view?usp=shari­ng

    But this is funny, the GPS info app itself is displayed fine: https://drive.google.com/file/d/1hkKc3vG­JANWkKPzuofrEuXv1Uid0vQkc/view?usp=shari­ng

    But the rest of the apps are shifted up, and widgets missing.

    Something is not ok.
    I was at ~2v09.30, and noticed the sliding and kitchen sink clock behaved strangely. I thought it's just a bit buggy :D But looks like not: now at 2v09.33, tried removing and reinstalling everything a couple of times, but the end is the same: Watch is displayed after boot, but if I try to open the launcher, the screen turns off, and can't get it back without reboot.
    Oh, and while I can delete and upload apps, there is not progress on the display.
    If I only have bootloader + morphing clock, pressing BTN2 shows "launcher not found" message. Pressing BTN3 turns off the screen, and can't get it back on.

    Reverting to 2v09.9 solved it (no particular reason for that version, just downloaded it previously to my phone).

    Wanted to write something similar, but was too lazy :D

    That's better. I can only guess, but you are abusing that poor CR2032 battery, a couple of things come to my mind:
    Battery itself. Do you test with the same battery? Or at least same brand, same state of charge? Might be simply the one with the MDBT42 breakout has less capacity, higher internal resistance, etc. Check the no-load battery voltage at least.
    Battery holder and leads: Lead length can affect resistance and inductance. Might be enough for different behavior. Lead length from battery to the uC in case of the Puck is minimal, in case of the MDBT breakout I guess it's longer.

    Do you have an oscilloscope to check voltages? Or if you don't have anything better, just sampling the voltage with any uC might help to get more info...

    Edit: a capacitor with smaller voltage rating, that would be physically smaller. And maybe even a low-ESR small-ish capacity one could help...
