I just use a bookmarklet that nukes any position:fixed elements on the page. Works on toolbars, cookie banners, full page interstitials — really shockingly useful on the hostile web.
There's a Sensor Watch simulator that demonstrates the features of the various firmware images; this one[1] is running the firmware that shipped with the first boards, and includes a clock, world clock (UTC by default, but customizable by holding the Alarm button), sunrise/sunset, moon phase and temperature. For the sunrise/sunset to work, you'll have to click the "Set Location Register" button, which will prompt for location access.
There are other versions of prebuilt firmware here[2], but my favorite one (even if it's a bit impractical) is the Stargazer firmware[3], whose second watch face can display the locations of the sun, moon and seven planets both in right ascension and declination, as well as altitude and azimuth if you grant location access. We're able to fit a truncated version of the VSOP87 model for planetary motion, right there on your wrist.
The Movement framework for developing watch faces tries to steer folks toward low power consumption by default; the watch spends most of its time in standby, and a custom watch face only runs code once per loop (which is once a second by default, although you can request more frequent updates from 1 to 128 Hz). This means most watch faces can actually stay under 10 µA as long as they don't need to update too frequently; up to about 16 Hz, power consumption remains decent.
Anecdotally, my daily driver is coming up on 550 days on the same CR2016 coin cell from February 2022, and I think it's on track to make it to 2024. A far cry from the original's 7+ year battery life, but still pretty good considering all it's capable of!
That is really impressive!!! Are you able to do some kind of power management on any attachable sensors as well besides whatever their standby current is?
I fed one of the reviews to ChatGPT and told it to write a review of the Burbank WalMart in this style. Result:
> Two Stars
>The Burbank WalMart is a behemoth of consumerism, a vast labyrinth of plastic and steel where the soul withers and dies. I wandered its sterile corridors, searching for some scrap of humanity amidst the endless rows of merchandise. But all I found was the dull glint of metal shelves, the hum of fluorescent lights, and the dull roar of consumerism.
> I took my chances with the food court, hoping for a glimmer of salvation. But all I found was a false burrito, swaddled in tinfoil and wrapped in a lie. I looked upon it with disgust, knowing that it was a symbol of all that is wrong with this place.
> As I left the Burbank WalMart, I felt a sense of despair wash over me. I had been to the abyss, and it had left me cold and empty. I will not return to this place of soulless consumerism, and I recommend that others stay away as well.
When you say “ I fed one of the reviews to ChatGPT” do you mean you put it in the input box and said write a review in this style? I wasn’t aware of this functionality!
Thanks for this. I'd been getting ChatGPT to write captions for my YouTube videos, but didn't realise I could seed it with a quote to push it from its usual pedestrian style.
Seriously, is this the future of HN? Seems every thread is infected with some loser going, hey, look what ChatGPT puked up about something nobody else asked about, or cares about.
i actually tried prompting chatgpt for mccarthy-style writing a few weeks ago, and like this it sounded nothing like him; more like a teenager who has heard somebody describe his writing trying to guess what it sounds like
oh hey, this is my project! Sensor Watch definitely has different goals — less smart, more watch — but I love this, and I love how the F-91W represents such a blank canvas for folks to project their vision onto. It's small and so very thin (at home on any person's wrist), water-resistant and vaguely indestructible. It's also so inexpensive and ubiquitous that you can take it apart and hack on it without feeling like you're breaking something important, and you can safely assume that anyone in the world can probably grab one at a local store and hack along at home. It's a wonderful object.
I made an Apple Watch app and complication a few years ago that averages $800 a month. I don't put any money into marketing or search ads, and it's been feature-complete since 2019:
The app is built around two small, simple features: today's date with a customizable format, and a three-year calendar so you can see what weekday dates fall on outside of the current month. It also supports several alternative calendar systems including the Islamic and Hebrew religious calendars, which I think may be another use case that drives sales.
Anyway: it's a one-time, two-dollar purchase that lots of folks are still finding and finding useful.
Weirdly coincidental timing on this! I've been working on a PCB design (FeatherWing form factor) to track weather data on my hikes, making use of a BME280 and a GPS module. First revision of the board[1], I discovered that the sensors started out accurate, then drifted up to a steady 3° above ambient. Probably because the GPS module was heating up. So last night I found myself reading up on design considerations for temperature sensors [2], including specific things like the cutout you have on the left side of this board.
I'm guessing you designed this — any advice as I embark on designing a second revision of my hiking log?
Jose - I have done a few designs for my current employer using the BME280 for environmental sensing. I've found it a little sensitive to heat, both from the environment and itself. There's a good resource from K&R Smith[1] about comparing the sensor to others and there's some discussion about how to set up the sensor to minimize self-heating. Might be worth looking into!
Additionally, when I do my designs, I place the BME280 sensor as far away from other components as possible (I see it is close to a SOIC chip on your board) and I route a cutout in the board around the sensor to reduce any heat conduction from the board. I also ensure that I have no power planes on the little resulting "island" PCB, and use small traces (with local decoupling) to further reduce any conductive heat. See the image in [2] for an example of what I am talking about.
Another alternative I pursued in situations where convective heat was an issue is to stick the sensor on a little remote board and use an off-the-shelf wire to connect the two (check out the Sparkfun Qwiic wires[3])
Overall you want to increase airflow around the sensor as much as possible so leaving it "hanging out" somewhere is the best approach to getting accurate measurements.
I'd been planning to use it with the Feather M0 Bluefruit, but for now I'm testing with an M0 Express with one of these LED displays next to it [1] on a board doubler. Good to know that this is more temperature rise than you'd expect to see; I'll have to confirm that (and measure the thing's current draw, which I have not had a chance to do yet). Thanks!
The BME280 is not particular suited for ambient temperature measurements. It's for accurate and fast pressure and humidity sensing. Quote from the datasheet about the temp sensor:
Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature.
You will get the temperature of the sensor rather than that of the environment. The tiny BME280 is thermal coupled to the board and also heats itself up during repeated measurements. For accurate ambient temperature you could use a DTH11 or DHT22. These come in plastic housings to isolate them from the surroundings and provide better airflow.
This reminds me of a short story by Paul Ford from a few years back[1]:
We had gone to a baseball game at the beginning of the season. They had played a song on the public address system, and she sang along without permission. They used to factor that into ticket price—they still do if you pay extra or have a season pass—but now other companies handled the followup. And here was the video from that day, one of many tens of thousands simultaneously recorded from gun scanners on the stadium roof. In the video my daughter wore a cap and a blue T-shirt. I sat beside her, my arm over her shoulder, grinning. Her voice was clear and high; the ambient roar of the audience beyond us filtered down to static...
I told my waiting daughter to go ahead and pay the few dollars, just part of the latent cost of a ticket. She tapped and the tablet made its cash-register sound, and the video was irrevocably destroyed so that it could never again be shared.
I had written (in college) a small story about an "RIAA Task Force" collaborating with the FBI to raid small brick-and-mortar businesses with occupants above some fabled "listener limit" that dared to have an FM Radio or iPod connected to a boombox in the corner of the store somewhere. Everything from Barbershops to Butchershops were raided, and the small infringing devices confiscated.
Given that the RIAA tried to sue a grandmother once, This wasn't too far-fetched.
Actually it would be either ASCAP or BMI that enforces this fee. When I owned a small restaurant, I had to pay for the privilege of playing CDs over a stereo.
It doesn’t cost Netflix any more money whether one person or 10 people are watching a particular subscription.
I’d say the major appeal of the drive-in is the venue and all the accessories (big screen, sound, etc) - otherwise you’d just pay for Netflix yourself and watch it at home.
Yes, that's the point: if not for the drive-in, you'd pay for Netflix.
A more interesting question is: why can't one create that drive-in, as long as only Netflix subscribers can enter? If "it's a license, not a product" like these companies shout, trying to prevent legitimate ownership rights, the license should work anywhere.
I mean I understand both sides of the argument, but it seems like physical goods manufacturers are doing fine without enforcing restrictions on how their goods are used (I am free to buy an off-the-shelf power tool and then rent it out without paying extra to the manufacturer), so why are we giving this exception to content producers?
In my opinion the law should be changed that content you pay for can be used as you wish except copying (otherwise you'd just copy it and resell). It'll drive up the prices of the "source" content, but the market will quickly fill the gap by offering affordable access to broadcasted versions of such content.
Because media owners paid off enough law makers such that they have insane control over how people use their products. It's analogous to a car manufacturer putting a device in your car that will drive it back to the lot if you let someone else drive it. Except it's all over software - something that costs virtually nothing if lost.
This is only for the big guys tho. Little guys get screwed harder than before.
