I have some bad news for you … the rest of the world outside school uses even more paper.

Because they’re likely not all using the same data. Some will be time delayed, from a different weather station, averaged over a different period, any number of variations.

- The temperature on the phone is likely an official temperature, measured at a specific location, under very precise conditions.
- The thermometer is in full sun, which is not at all either standardised, nor under any controlled conditions, for example, you’re holding it and your temperature is 37°C.
Temperature is measured like this:

Have you considered that the temperature displayed by the phone comes from the internet, rather than an onboard thermometer?

If and when this becomes mainstream, we’re going to need better software than OpenSCAD, FreeCAD and Blender to actually design the things you want to build.

According to this source: www.legislation.gov.au/F2021L00617/latest/text
460 – 470
FIXED
MOBILE 286AA
Meteorological–satellite (space-to-Earth)
287 289 AUS98286AA The frequency band 450–470 MHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT) — see Resolution 224 (Rev.WRC-19). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations. (WRC-19)
287 Use of the frequency bands 457.5125–457.5875 MHz and 467.5125–467.5875 MHz by the maritime mobile service is limited to on-board communication stations. The characteristics of the equipment and the channelling arrangement shall be in accordance with Recommendation ITU‑R M.1174‑4. The use of these frequency bands in territorial waters is subject to the national regulations of the administration concerned. (WRC-19)
289 Earth exploration–satellite service applications, other than the meteorological–satellite service, may also be used in the bands 460–470 MHz and 1 690–1 710 MHz for space-to-Earth transmissions subject to not causing harmful interference to stations operating in accordance with the Table.
AUS98 The harmonised frequency ranges in the 400 MHz band are used for national security, law enforcement, and first and second responder agencies. These agencies include police, fire, ambulance, and emergency rescue. These agencies are normally consulted about use of this spectrum for government purposes via the Commonwealth, State and Territory representative arrangements established by the National Coordinating Committee for Government Radiocommunications[1]. The harmonised band comprises the following frequency ranges:
- 403–403.98125 MHz,
- 405.01875–406 MHz,
- 408.64375–410.54375 MHz,
- 412.46875–413.43125 MHz,
- 414.46875–415.44375 MHz,
- 418.09375–430 MHz,
- 457.50625–459.9875 MHz,
- 467.50625–469.9875 MHz.

- Comment on HF antenna placement, rx v tx performance, rain gutter antennas 3 weeks ago:
5 Watt is plenty to be heard. A more important question is, when are you trying to make contact?
I don’t know your experience level, so make sure that you’re doing this when the band is noisy, not when it’s quiet, especially on 40m.
Also make sure that you are aware of solar storms and geomagnetic disturbances, but if you can hear others, that’s a great start.
Think of making contact as flyfishing, it takes patience and practice!
Good luck.

Not sure what you mean. When I click the link on my post, it goes to where I intended. Note that I removed an errant period at the end of the URL about an hour ago.

Thank you, fixed.
- Comment on Your Truck is Stupid Big 3 weeks ago:
I think that it’s going to take societal change to stop this from being the norm. In Australia there was a road safety campaign with the slogan:
“Speeding. No one thinks big of you.”
It essentially compared speeding with having a small penis, by using the metaphor of a wiggling pinkie, and thus embarrassing perpetrators.
In other words, it needs to become uncool to drive such a massive vehicle. Perhaps “The bigger the trick, the smaller the …”

- Comment on How should a news article website financially sustain itself? 1 month ago:
I understand your concerns and I have as little confidence in the concept of crypto as it currently exists as you’re expressing.
I had no intention to peg a user’s CPU, but if we extend the concept of CPU cycles for content, perhaps a browser could process some data or make calculations, like say data analytics, or some other distributed process that would benefit the author and in doing so would allow both to have a win-win experience.
- Comment on How should a news article website financially sustain itself? 1 month ago:
Can you elaborate why you think that your comment requires a sarcasm tag?
I’m asking because getting the reader to contribute some CPU cycles whilst they read your content seems to be a way to balance the books, they get something from you, you get something from them.
Note that I’m not a fan of Bitcoin et. al., but the idea of making the reader’s computer calculate something or process something on the authors’ behalf seems, at least at first glance, a valid and potentially unobtrusive transaction.
