#BangleJs
Are you a nerd? Do you like #javascript ? If so, maybe you ought to check out #banglejs https://www.espruino.com/Bangle.js2
I got one and i friggin love it. Seemingly endless battery life and JS on my watch, are you kidding me? Plus, it does not spy on you ❤️

BangleJS 2 -> Test gadget
Firmware 2.16 ->This analysis applies to the algorithm supplied with this firmware. The measurement quality may be different in other firmware versions.
Amazfit bib -> Reference gadget
Firmware V1.1.5.36
Reference smartphone step counter Paseo (https://f-droid.org/en/packages/ca.chancehorizon.paseo/) -> Reference gadget
Verision 1.6.2
Steps were recorded hourly during the day (mostly after one hour) for five days
Comparison is shown between Bangle JS 2 and Amazfit bib only.
The step counts for the Amazfit bib and the Bangle JS 2 are shown for five days.
Per day, three plot are shownScatter plot (x = Step counts Amazfit bib, y = Step counts Bangle JS 2) with a linear regression line for visualization.
Scatter plot (x = Time as hour in a day, y = in red is Step counts Bangle JS 2 || Amazfit bib)
Time-series (x = Time as hour in a day) withe the Difference between the counted steps between the Amazfit bib and the the Bangle JS 2 (Steps_Amazfit bib - Steps_Bangle JS). Red bars indicate periods with higher levels of moving (e.g. continuous walking, running, …)
Amazfit bib and Paseo (reference gadget, https://f-droid.org/en/packages/ca.chancehorizon.paseo/) give almost identical results (not shown)confirms that the Amazfit gives reliable counts for the steps
Difference between Amazfit bib and Bangle JS 2 is considerable (-2474 – 6325 Steps)During periods of low movement, the differences are small
In some days (Day 1 \& 2) the difference between the counts seems ok. However, when comparing the absolute numbers, the differences are large
For the majority of days, the differences in step counts increase as the day progresses. Although the curves are the same, the Bangle JS 2 always underestimates the step counts.
It is not possible to determine when the differences are particularly large. However, it seems likely that this is the case when long periods of more intense exercise have taken place.
The Bangle JS 2 is a handy gadget. However, you should not rely on the step counter.
Bought myself a programmable smartwatch (https://banglejs.com/) hoping to get my brain working with some simple coding. Sadly still too ambitious for #LongCovid but at least on visiting my student son he has something to play with while I nap on his bed! (I got some tweaks to Smartwatch Apps out of it too. A win-win) #BangleJS
I never understood the hype surrounding smartwatches. But then I found out that there is one that I can freely program using Javascript. I have a smartwatch now 😍
Choices for watch faces that display numerical seconds on #BangleJS 2: super buggy (Anton Clock+ which ignores most of its settings and won't display the day of the week or the week of the year even when those are turned on) or barely readable (Simple Clock With Date, which uses an LCD font).
And, of course, if I use either of these, my battery life goes to shit, because it has to execute a bunch of JavaScript and font rendering code every second.
I'd tolerate not having seconds if there were ANY timer that was reasonably fast to set. But the touch screen on the watch is fairly terrible and often takes multiple swipes for a swipe to register. It also requires a separate calibration app which for whatever reason is not loaded by default to register touches in the right place.
It's the third smart watch I've owned, and I've never been happy enough with any of them to keep wearing them. I think smart watches just aren't for me. I think I'm going to replace the battery in my Chase Durer pilot's watch and start wearing that again.
Today was a good day: fixed a bug that had been annoying me for weeks, and upgraded some code to the point where I could strip out an ugly hack.
Hmm, displaying seconds on my #BangleJS 2 seems to cut the battery life down to less than a week. But I don't want to make it only display seconds when it's unlocked, because then I'd have to set it to unlock on twist, which IMO defeats the whole purpose of the #transflective #LCD.
I wonder how much displaying seconds on my #BangleJS even when it's locked is going to reduce battery life?
I wonder if I even care? It's too much of a pain to set a timer for short intervals. It's easier to just use the clock.
Doing a spot of #BangleJS tinkering
Thought I'd re-post some of my #projects here that I had originally tweeted now I've deactivated *over there*.
This project was to interface with an Aidex glucose sensor and display the live data directly on a Bangle.js watch:
https://blog.ivor.org/2022/03/sniffing-sugar.html
I should re-visit this at some time to handle the full protocol (the patch stores data you can download) but that interaction is encrypted.
#banglejs #glucose #cgm
Allez hop, je redonne une chance à ma #banglejs 1:
* mise à jour des apps
* mise à jour du firmware
* réactivation dans #Gadgetbridge
Fixed a bug in my #BangleJS messages app. Phone notifications were quite annoying today, as every one reminded me that I broke my watch.
Yay, and it just got merged, so coming to a #BangleJS app store near you soon!
Ah well, so much for my plan of checking out #twinkly-animator today, foiled by working through my #Bandcamp backlog and cleaning up my #BangleJS repo.
As usual, "Just a small bugfix" turned into a massive "clean up a tiny bit of cruft and rebase and figure out why CI is broken and restore some things that weren't actually cruft and update my firmwares".
Surely tomorrow will be more "productive".
Using the Calibrate app on the #BangleJS 2 makes a huge difference in the accuracy of the touchscreen. Makes it a lot less frustrating to use.
I might be annoyed that Weather Notification doesn't let you change the units if it actually displayed on #InfiniTime.
From what I've been able to tell so far, #InfiniTime is simply not very useful with any #Android distro except for #LineageOS because the #Gadgetbridge devs don't care about it. I've already bricked one #PineTime trying to load #WaspOS, so I'm afraid to try again, but it appears to be the more useful OS.
I guess I can give it a shot and then if I brick the second watch throw them both in the trash and get a #BangleJS?
In the latter category I know of the already mentioned #PineTime, the #BangleJS and #Watchy

@pluralistic Aaaah... I still haven't found time to fiddle with my #banglejs watch and teach it to recognize laps when I go swimming in the pool
