It seems like the opposite has happened: the west now depends on authoritarian regimes, and even if their values aren’t winning the day, their willingness to use force in the pursuit of power is. This is all so wrong, and my heart breaks for everyone caught in the middle of it.

Military intervention is out because of nuclear saber rattling, but then Europe refuses to impose real sanctions because it’s cold and they need Russia’s natural gas? They told us free trade stopped wars, that economic interdependence would fuel the advance of democratic values…

I haven’t been tweeting much about the Ukraine situation but I have to ask: does the international community have any plan for this other than “let it happen?” Putin invades a sovereign nation to overthrow its democratically elected government and the world sits back and watches?

One year ago today I went on the @adafruit Show and Tell to share Sensor Watch progress. I’d just gotten it to count seconds, and to show a word (green) when the green LED was lit. Basic stuff, tho we do more now; good to remember that the work takes time. https://youtu.be/GBdo1UBhCOE?t=1100

Does anyone get this alert constantly? I swear I’m not refreshing twitter that often, but every two or three days I’ll get this message when loading bird site and I’ll have to come back like an hour later.

Is there an astronomer in the house? I’m soliciting feedback on my addition of astronomy data to Movement, the community firmware for Sensor Watch. More info here, including a instructions for and a link to a live demo of the new “Astronomy” watch face: https://github.com/joeycastillo/Sensor-Watch/pull/55

I have no idea how I got away with this, but it looks like I might be able to build this board after all! There have been 5 SAM D10’s available at Microchip for weeks now, but the MOQ was 80,000. I figured, hell: what would happen if I just added them to my cart? Answer: got ’em!

Might be good though; I know for a fact my time zone code isn’t nearly this robust. https://github.com/evq/utz

Replying to @getur and @cmenscher
Wow yeah I’m looking at a time zone implementation that I could incorporate into the watch firmware; this subject clearly evokes strong feelings.

Replying to @cmenscher
Just watched it! Believe it or not the watch already has to deal with leap seconds; turned out to be crucial for planet tracking. (I used someone else’s public domain code for this; seemed like the kind of thing I was unlikely to get right 😬) https://github.com/joeycastillo/Sensor-Watch/blob/1aac7bf535a9170aaf4aea820dcd81746eb3647e/movement/lib/vsop87/astrolib.c#L91

This little excerpt of a table references four weekdays, seven months, two calendar systems and one island that only moves the time by a half an hour, for a laugh.

got it in my head this morning to implement a daylight saving time setting on the watch and my god, how do we live this way?

That’s the F-91WM-3ACF! Got mine from thecasiostore on eBay; reputable seller, my preferred source for authentic Casio watches whose warranty I want to void immediately https://www.ebay.com/itm/183499601419

Battery test, day 105: 3.00 volts, the end of the @crowd_supply campaign and the beginning of two more battery tests! Our low power situation has improved so much, a new test makes sense. I’m giving the green one to a friend this week, and I’ll be checking in throughout the year.

I’m actually using the MTA’s own API! It’s been a while since I did this but as I recall it was easy enough to get an API key and then query them directly. https://gist.github.com/joeycastillo/12273bd0befc297f20f61146fa9806f5#file-trains-py

Most of the heavy lifting though is done with Babel, my Adafruit_GFX compatible Unicode text display library. Funny thing: all those circled G’s and M’s for the train lines are actually Unicode code points for letters enclosed in a circle. https://github.com/joeycastillo/babel

holy wow I went to check and it actually is, uploaded November 2019! Not sure the layout code is something to aspire to; tho. 😬 https://gist.github.com/joeycastillo/12273bd0befc297f20f61146fa9806f5

I could have sworn I’d starred it before, but just did it maybe again! Also thanks for the watch mention in the Python on Hardware newsletter; I’m really stoked to get that over the finish line this month :)

(but apparently I’m using it to successfully classify motion data!)
(original)
Replying to @josecastillo
It’s especially cool to be able to explore features of the data to see it as the machine sees it. Jogging for example has the most “oomph” (RMS), and while the frequencies in the idle signal are all over the place, its peak height is small. I don’t know what spectral power is. 😬
(original)
Added one more class to my @EdgeImpulse motion classifier (weight-lifting) and it’s giving me a better understanding of how this is working! I’m not going to risk explaining things I don’t fully grok yet, but the tools are definitely helping me to get to that understanding. 1/2

It’s in north Brooklyn! Runs north/south between Greenpoint and Williamsburg. I don’t know who it’s named for though!

Replying to @zach_shelby and @crowd_supply
The big restriction is, you can’t use the A168 with the electroluminescent “Illuminator” backlight; the internals on that one are significantly different, and aside from not being able to drive the EL panel, the Sensor Watch board simply doesn’t fit.
(original)
Replying to @zach_shelby and @crowd_supply
Haven’t tried an A159, but it should work; I’d be shocked if it were significantly different inside. The A158 just has an F-91W movement inside.
The back polarizer in the A159 might be different like the gold-tone F-91W, but everything else fit exactly the same in that one too.(original)
Replying to @RWB93174525
Definitely! Interestingly I’ve found that the tri-color displays with red tend to fade a lot more, but the black/white and black/white/yellow seem to stick around forever.
(original)
Not sure what Sensor Watch is or why you might want it? @tomfleet has a great write-up over at @Hacksterio outlining what the board is, how it works and all the things it’s capable of. And hey, even if you already preordered one — check it out anyway! https://bit.ly/33FQRaS

oh and also IT IS YOUR LAST CHANCE TO BACK SENSOR WATCH ON @CROWD_SUPPLY! You have barely more than six hours left to get in on the first run of this ultra-low-power ARM Cortex M0+ board swap for the classic Casio F-91W (and stainless steel A158)! https://www.crowdsupply.com/oddly-specific-objects/sensor-watch

also found in the old projects bin: an absolutely ancient Open Book prototype strapped to a 7-inch e-paper screen, still displaying subway departures from probably late 2019. This glass is so thin I’m shocked it hasn’t cracked into pieces by now; I should print a frame for this.

Took it to the shop to fix that one wire, and now I remember: conference-call-from-hell simulator. (this was actually going to play different sound clips for a friend’s art exhibition, but it was slated for spring 2020 and we all know how that turned out)

The Great Search this week yielded an (in-stock!) I²C LCD driver that can drive 48 segments. Got me thinking about an I²C LCD FeatherWing. If you could come up with any layout you want, what would you do with 48 segments in a Feather form factor? https://www.youtube.com/watch?v=H55Ljn8ya3Y https://twitter.com/adafruit/status/1495584376222105601
