I don't like that my Bosch e-bike batteries have closed-source schematics, software, and chargers (i mean really, what the fuck am I going to steal Bosch), nor that the software that runs on the bike is utterly locked down to the point where I can't even pay for a copy (it's available only to e-bike dealers and none of them have leaked it as far as I can tell), but unfortunately, I have no trust in my fellow schmuck to not accidentally or negligently build bombs when they rebuild their battery packs, nor would I trust them not to do stupid shit with the e-bike software like remove speed limiters.
I barely even trust myself to rebuild packs, and I kinda-sorta know what I'm doing, which is just enough to get myself into trouble. I still look at the two packs I have rebuilt with a side-eye, months and years on from when I built them.
I’m not going to lie, this is the first thing I would do if I could flash e-bike software.
I'm tired of being treated like an idiot consumer because someone, somewhere, fucked up their Li-ion battery.
Battery fires are not hotter. An EV battery fire and ICE car fire actually have fairly similar heat energy profile. ICE cars are a bit more intense. There’s a study from Sweden that set fire to similar ICE and EV cars and measures the energy. A gasoline tank will typically store a lot more raw energy than an EV battery.
They are self oxidising if the electrolyte burns away. That’s true. The anode and cathode is shorted and you get thermal runaways. That’s why it’s a bit of a challenge to fully put out a battery fire. Next gen solid electrolyte batteries fixes that to some degree.
Of course you can extinguish a battery fire with a fire extinguisher, or just water. The problem is that thermal runaway will make the battery really hot again, which will reignite anything flammable around the battery. So you need to keep it cool for a long while, generally by spraying or submerging it in water.
We actually had an issue with this at Robocup one year, where one of the teams charged their battery at 3C and then blew it up. We didn't have a Class D extinguisher within reach, so we blasted it with a CO2 extinguisher while someone ran to get a class D extinguisher. The battery kept burning after blasting it with the CO2 extinguisher, but at a much reduced pace, and the perpetrating team took a selfie with their burning battery.
Humans will lie and cheat for profit but at the same time humans also build locked batteries. It's just that nowadays we take away responsibility of people and their choices and we don't want to deal with the fact that when someone is buying a shitty poorly built copy, they are the ones at fault because of their greed.
You could very much have an open market (and should) it's just that people would rather believe there is nothing wrong when they buy something that is suspiciously cheaper than it should be.
Greedy corporations are at the origin of the problem precisely because they try to extract too much for their stuff, selling it at what is an unreasonable price.
You cannot at the same time blame people for their poor choices out of greed and at the same time re-enforce the same behavior in corporations, that's nuts.
Engineers need a union. I'm sure this was a bean counter decision and not something they wanted to do.
Battery packs can be expensive and have huge margin if you make them (mechanically) fit only 1 year of 1 model of 1 brand. Which is exactly what Dyson seems to be doing.
Designing BMS'es so that the batteries (safely) fail as quickly as possible is not hard.
Push forward, push backward, lift up cord and turn to the right
In terms of maintenance and performance the Oreck is a reliable, one-click WordPress install, and the Dyson is a few dozen fickle micro services.
I got the Oreck for like $20 on Craigslist a decade ago because it was listed as "broken." I bought it on a whim to see if I could repair it after one of the famous vacuum guy reddit AMAs. Without exaggeration, it may very well be the best $20 investment I've ever made.
I was amazed how simple it was to disassemble and reassemble. There were surprisingly few components and every single one had an appealing heft and remarkable quality.
As a somewhat funny aside: The woman I bought it from said she had three teenage daughters and it couldn't keep up. The first time I serviced it, I removed enough hair for several wigs.
Ever since, it's worked incredibly and in the rare event performance has started to suffer I've been able to service it myself multiple times over the years, and replacement parts are readily available. It's designed to be maintained. After each service it works literally good as new and I fall in love with it all over again.
Contrast that with my hand-me-down Dyson. It's awkward as all hell to store. Battery is pathetic and charging is a pain. So much delicate plastic. It clogs practically every use; though to be fair my children and animals are all filthmongers. The components feel cheap, and I can't help but feel like it's hostile to the average consumer attempting to repair it. It's deteriorated in performance even though I've used it lightly. If I had spent even a single dollar on it, I'd be so pissed.
My first confrontation with a 'Dyson Airblade Wash+Dry short hand dryer' was after paying 50ct to enter a newly modernised toilet on a Dutch railway station. I got totally splashed with water blown out of the sink, all over my clothes. Quite embarrassing to walk out a toilet like that.
The last time the battery failed we decided to buy an entire Shark cordless vacuum + accessories kit for less than an OEM Dyson battery. That shark vacuum is still going today 5 years later on the original battery.
The cost multiple of a Dyson doesn't even result in incremental performance.
The singular use case for a Dyson cordless is frequent cleaning of an uncarpeted floor in a public space (e.g. coffee shop, gym) as it does have substantially reduced noise while running.
This problem was solved before electric vacuums ever even existed. I can still remember the days of seeing these things being used in hotels and restaurants: (google non-electric electrostatic sweeper)
The suction on the dyson v12 is fantastic at max speed, so it’s great for quick carpet cleaning. I also appreciate the very quiet hardwood floor attachment. I’d recommend it to any apartment dweller that’s not cost conscious. If they are, i’d recommend a cheaper shark vacuum.
Still have that purple and grey beast. Best vacuum by a mile and still going.
And im not judging, i too was a broke college kid at one point. And many people just don’t have the money. But ikea is ANYTHING but fancy. Its super cheap.
I'm curious where people are buying "real" furniture, even even they spend "real" money. I've had the best luck with the Amish and at estate sales, but that's not super repeatable.
All the major furniture stores like Ashley or whatever are similar in quality and construction to IKEA -- I don't really think the "cheap" reputation is deserved just because IKEA has $10 LACK side tables available.
I personally recommend people go to a real furniture store (a large one), where the salesperson is actually knowledgeable and where they offer many brands. Ask for what you want. Specific materials, finishes, price range, etc. Make a note of the brands and manufacturers. Then dig deeper. Often times these brands are featured in a niche catalog or magazine, where you can find similar brands offering similar products.
There are many high quality buy it for life items to be found! But rarely at the convenience of a button click from westelm’s website.
In the Seattle area, the best I could find is Dania, which is a chain that is basically a higher end IKEA that focuses more on furniture (Scandinavian style).
Some brands that you might like if you are looking for buy it for life. Some sell direct, some only sell via wholesale to other furniture stores. This is a list from a note i created 3 years ago when i was shopping for a new dining table.
* MS&Wood. Bosnian company, 100% wood products. https://www.adakezic.com/images/Zastupstva/mswood/2018_MS&WO...
* Ethnicraft - 100% wood (oak, teak, walnut). made in belgium.
* Cattelan Italia. Italian company, very high end and also very high quality. Styles are a mix of gaudy and timeless - wood, glass, and metal.
https://www.cattelanitalia.com/en/products/index?c=new
On the lower price range, some good choices might be “Article”, “Blu Dot” and “HAY”.
I will never understand why there are always such comments saying Ikea furniture is bad quality, or in your case not even "real" furniture, come on, it's like you have never even been in an Ikea store.
I think Ikea is wonderful on a budget. But i personally wouldn’t waste my time there, except for rarely used pieces of furniture. im blessed to have more discretionary income these days. The one product i really like from ikea is their PAX closets. I think they are a very good value, despite feeling a bit cheap. I like how customizable it is, and it’s very functional.

For example the Amish make very high quality wood furniture in the U.S., at a fair price. If that’s not your thing, there are companies that focus strictly on buy it for life high quality wood furniture. My dining room table was made by MS&Wood (based somewhere in bosnia i believe…they sell direct and wholesale to furniture companies).

It was announced a month ago and seems to handle the design criticism in this blog entry. If it works as well as demonstrated will put it in a new class of vac.
Isn't that the whole point of them? Instead of imparting enough heat energy to evaporate all of the water on your hands, they just push it off which is much faster and more energy efficient. How would they work better than regular dryers without doing that?
There might be more to the task though. What affect does it have on the user? Getting splashed with water, usually at crotch height, is a nuisance and is somewhat embarassing. The loudness of these dryers is also a nuisance, and can be downright painful depending on how many are going at the same time in a large public bathroom. Long enough for permanent damage? Probably not for the average hand-washer, but for the people who have to clean those restrooms all day, perhaps an occupational hazard.
Also, the trough shaped ones are disgusting.
When used correctly I find they don’t spray too much water around and dry my hands almost immediately.
* The industrial design of Dyson products is generally great. I don't think they poke you or anything like that. They even have nice affordances like all the things you can use being red. Contrast that with my terrible Shark where everything is black. Took me a good few seconds to find the bin release button. It also has an atrocious UX - a slow on/off button instead of a trigger, and an amazingly useless "smart power" feature that just varies the power almost completely randomly as you vacuum.
When I worked there all the vacuum guys were worried about Shark because their pickup is apparently better. They needn't have worried because their UX is so abysmal. Although I guess in fairness Which doesn't know UX exists.
* Some of the criticisms of the tech are valid, e.g. the hand dryers spraying water everywhere (they easily erode painted walls and now they generally install them only on tiles). But those are just flaws of the tech, they don't negate the fact that the hand dryers are much better than the standard cheap ones. He quotes the claimed hand drying time for a cheapo dryer as being close to an air blade but anyone that has ever used one knows how much of a lie that is. The washing machines did damage clothes but apparently the main reason they stopped making them was a manufacturing issue with the drum.
* I don't think anyone really believes that James Dyson is personally inventing all Dyson products now. That doesn't mean he has no influence. When I worked there (about 10 years ago tbf) he still had huge influence over the designs, especially the ones he cared about.
The one thing that is true is that Dyson won't make anything that isn't patentable because James Dyson dislikes his products being cloned so much. So even though though could make really good versions of normal products, they don't.
Also they are way too expensive. Though in fairness my shitty Shark was expensive too.
Don't buy a Shark.
No sense charging top dollar and using less than state of the art batteries.
What is "Which" in this context? As used here it appears like a proper noun.
Contrast that with the Dyson v15 which has a trigger I have to hold continuously while I twist and turn the vacuum so I can't change the grip without it turning on and off as my finger slips off the trigger or inevitably gets tired. Or the amazingly useless "smart power" feature that just varies the power almost completely randomly as I vacuum an otherwise perfectly smooth hard floor.
Or the peak of uselessness, a display to tell me how many particles of dust it thinks it vacuumed, and their estimated sizes. Because I needed to be told I vacuumed 20 million dust particles of one size but only 1 million of another size. Counted twice just to make sure.
The triggers are so light, I fail to see how anyone could get tired. It basically requires no more grip than just holding it.
> Or the amazingly useless "smart power" feature that just varies the power almost completely randomly as I vacuum an otherwise perfectly smooth hard floor.
Oh no Dyson did that too? I assumed it was just Shark.
It's clearly a hack so they can lie about amazing pickup and battery life (....but not at the same time)
sort of like the humdinger, which I think I wasted my money on trying to replace a dc34
I think of a Dyson as more of a status symbol, like the latest Mac Book, a watch collection, or a Porsche. Dyson owners like telling people they have a Dyson. Most people just need things to work well for their use case, be reliable and affordable.
The saying goes... "Fast, reliable or cheap. Pick two."
I wanted to explore how the focus on tech-centrism impacts the product design and styling. I do think Dyson makes compromises on cost and ergonomics to uphold their brand values. Does that mean the products are bad? No - but I think they could be better. Do I think a lot of other products on the market are far, FAR worse? yes. But Dyson asks us to hold them to much higher standards (and pay a lot more). So I think serious design criticism is warranted.
Dryer time - there is a huge spectrum here. There are many dryers which cost a fraction of an airblade and dry with similar speed. My real point is that dry speed is a key factor but not the only factor, and that I believe other manufacturers have set their design decision-making with a different set of priorities.
You make a good point about colour-coded interaction points - and the consistent application of those colours across the vacuum product range is good as well. I intend to update the article with some feedback and I'll be sure to mention that for balance.
Regarding James Dyson and the invention culture: I worked with senior ex-dyson designers some 6 years ago so have some 2nd hand awareness over the IPR culture and JD's oversight of design reviews. I agree that I don't think the public literally think that it's JD himself inventing things (though, he is certainly more involved in design than a typical CEO). Yet the objective of the Dyson branding is surely to ensure that the name James Dyson is firmly in the public consciousness as an inventor extraordinaire. I think that is a conscious choice by Dyson and that it has a sizeable influence on societal perceptions of the design profession.
Cheers!
Everything will be worker and independently owned (bootstrapped and no VCs), no patents (we don't care about clones)
Just make great product that is open has free software.
If there would be significant interest Dyson could have a direct competitor just like many other open source companies like System72 and Red Hat
Still some of the criticism holds, such as the terrible wall charger.
I think their brand isn't just about tech itself, but the utility exploring novel tech can drive.
The humdinger should be a more modern replacement, but it sucks. No trigger, no fun.
Dyson's brand is to be technologically forward. It is supposed to look like the future, which is why the angular mix of colors works for the brand.
Bosch, I have no idea what their brand aesthetic is, or what they are trying to say.
This doesn't mean that the Dyson is better than Bosch, or any other competitors, just that brand does come into the equation as well.
Yes, it is heavy, and corded, but it is a beast, and still amazed at how much dust it gets every week.
I have to admit that I am not impressed at all by the latest Dyson cordless versions, including the new Dyson PencilVac (https://www.dyson.com/discover/innovation/new-machines/penci...).
And so I need a vacuum that is not going to lose power, so I am happy to stay corded, with full sucking power all the way.
I can see the Pencil useful for a quick limited vacuuming.
It has a headlight.
I’ve had the Dyson DC02 (1995) - great machine, rubbish plastic in the handle which always cracked after 5 or more years. The filters were also a terrible, throwaway design.
Then bought the DC25 (2008). The DC02 still worked, but this was a dramatic upgrade, solid, strong, easy to clean the brush bar (a long haired dog and 2x daughters made this a god send feature) and easy to wash filters.
Then bought the DC16 - their first cordless. Appalling suction and batteries which died after 1-2 years of use.
Next decided to try a different brand and bought a Miele CX1 (2019) - their first bag less cleaner. Highly rated, very expensive. It had the worst brush head I’ve ever seen, required fiddly disassembly to empty the weird little dust compartment within the canister and had a very odd dust filter which was a pain to clean. Terrible vacuum and lousy design compared to our previous Dyson.
Now we have the V15 - phenomenal cordless vacuum. Can’t praise it enough. It’s just a vacuum mind but it’s very good.
As an aside we’ve also bought the Dyson fans for work. The circular one worked well the HP02 heater purifier which cost a fortune has a high pitched whine which is so irritating that everyone turns it off and this is despite Dyson reluctantly taking it back and ‘fixing’ it - whereupon a year later it’s back to whining.
Dyson himself seems a hypocrite and a little questionable - between Brexit and then incorporating in Singapore and also buying swathes of British farmland I’m not exactly enamored. Also backing out of the Dyson car seemed a low ambition move to me given he has total ownership of the company and is one of the few people in the world who can make that kind of impact.
But the article itself just seems a nothing burger.

In the future we're going to regret breathing bad air. It's the accelerant for so many health problems.
eddythompson80•7mo ago
A non-oxygen dependent energy system for the human cell is the only option moving forward. We need to utilize a clean energy source like sunlight and dump that oxygen dependency once and for all. Cyanobacteria was a crutch dependency that helped bootstrap that whole life thing pretty quickly for the demo. We have a proven concept now that we know work. Can we leave the idea to use oxygen back in the GOE era where it belongs now? Building all this complexity on top of a fundamentally flawed bases like oxygen reactivity was the main mistake.

Oxygen is an amazingly energy rich fuel and is super abundant for us. The oxygenation of earth was one of the key steps, and it might be a "hard step" for other civilizations.
Of course oxidation causes a lot of damage and byproducts, and is one of the causes of our aging and death. But without it, well...
I was primarily referring to particulate matter suspended within the air we breathe. High PPM / particulate measurably reduces lifespan in several population studies, and it also produces noticeable pulmonary and cardiac disease states.
Polluted air is bad.
