More concerning - can anyone explain why there is such a variation in the results from the DC powered unit vs. the TENG-powered one? The graph at the bottom of the report shows a difference of 30-50ppm between both units when they are sitting side by side on the bench.
That’s if the voltage supply was stable and within electrical specs for a sufficient period of time. We can see this is a snippet 2 hours into the discontinous collection.
3.6V is the maximum value that the nrf52832 SoC can handle. I would suspect the VDD is variable.
I skimmed the original article and it only mentions the graph and says that it's "comparable to DC powered unit". I'm guessing < 100ppm difference is somewhat acceptable?
It’s crazy to think that many people alive today experienced a 30% increase in ambient atmospheric carbon dioxide concentration within their lifetimes.
I have to know, what's the the rise of people like you chiming in with AI sourced tidbits? It's like the people with no knowledge on a subject that use google as a quick catch up tool so they can participate in a conversation, but somehow even worse. Are they the same people, but now lazier or just true believers in the non-sense engines?
You’re missing some deeply important context there, which is that those measurements are for outdoor atmospheric CO2 only.
Average indoor air quality ranges from 400-1000 ppm CO2, with adverse mental effects starting to appear close to 2000 ppm.
In that context, you can see why a 50 ppm difference is marginal. This is why asking an LLM is not generally a great idea for understanding something - you need to follow it up with more research.
I really wanted to like Stage Manager. I feel like there was something there in terms of window management that hadn't really been done before, but there was just something about it that wasn't quite right - the gestures never seemed intuitive or something, and I'd end up having windows shuffling all over the place whenever I was switching task.
I look forward to seeing the changes ipadOS 26 (with the possible exception of liquid glass)
I'm working on a construction project right now (not as an architect/engineer) and I can tell you right now that live collaboration is THE killer feature (your slick UI not withstanding).
If this job is anything to go by, the current state-of-the-art appears to be a single Revit model file released once a month, 10,000 excel spreadsheets and 3,000 PDFs of various versions and quality spread between Sharepoint and a Document management server.
I'm sure you've got an amazing roadmap, but it would be great to see you apply a modern take on:
- how to handle version control in a multi-user environment (endless designing is fun, but at some point you need to draw a line in the sand so that people can start work, then changes need to be highlighted for the guy on the ground swinging a hammer)
- collaboration with 3rd-parties that may have a subset of design responsibilities (e.g. HVAC, electrical - they can place things in a room, but can't adjust the dimensions of a room)
- design reviews - current state-of-the-art seems to be marking up PDFs of DWGs with comments (which the supplier completely ignores on their next revision)
I look forward to watching this product evolve!
Small typo on your Love Letter to Designers post:
"A promise we will make at Arcol is tolisten first"
THIS! I'm working at a large construction project now, and am continually amazed at what "state-of-the-art" realtime 3D in Revit looks like. Yes, all these corporate laptops have shitty GPUs, but come on, I got better fidelity in Quake 3 Arena 25 years ago on machines with 1/10th of the spec.
To be fair, these are the companies that pay for the level of industrial design that Ive produces, and after spending the latter part of his career at Apple knocking out revisions of existing products, probably made a nice change.
I think it's fair to say that most companies building products priced for Mr/Mrs Everybody don't spend a dime on design where there is already a market leader to copy inspiration, or outright steal from (see almost every phone made since 2007).
The Gold Watch was probably an opportunity to work on an interesting project with a new material.
Oh man - I used to have a Harmony remote and thought it was the best thing ever for my multi-vendor AV setup...
...then the AppleTV was released, with a remote that made the Harmony look like the console of a nuclear power plant by comparison, and I never went back
Haven't read the full article (paywall), but the biggest issue with co-mingling livestock and solar panels is the damage they cause to the installation by chewing through or rubbing up against insulated wires.
Also, when the panels are at full extent first thing in the morning (e.g. almost vertical facing east), it's very easy for animals to come in contact with the panels themselves.
The corollary to this (at least in Australia) is that most solar farms are being installed on (now) vacant grazing land where 150+ years of cultivation has meant that the grasses that grow on them are very fast growing and hardy.
Mowing the fields beneath the panels is a full time job just to reduce the fire hazard.
Aussie in AU here - I think about this opportunity a lot too, but sadly it will not be our government that delivers this outcome if the current nuclear vs. solar/wind debate (like these are mutually exclusive outcomes) is anything to go by.
I had high hopes that Andrew Forrest might be the one to pull this off after watching him deliver this [1] Boyer lecture 4 years ago, but as far as I'm aware this none of this has materialised.
Yeh I loved twiggy for a while there but then he went all in on the hydrogen bullshit, and now those hydrogen projects are getting wound down before completion (aka fumbling the ball).
In general I think the east coast and the national energy market is cooked, I'm not sure how, and when the pioneering spirit died but it did. On the non-fatalistic side EV and rooftop solar uptake are great, so who knows?
On the other hand I'm much more optimistic about WA, they seem to be quietly making the correct decisions as far as I can tell. Expansions in desalination, huge battery projects, green industry (ammonia up in the pilbara [1], and inroads into the lithium supply chain in kiwana).
Let's see how this all shakes out, and hopefully the public rejects the pro fossil fuel / nuclear bullshit.
