Dyson is crap

A friend lent me a Dyson bladeless fan (first bullshit, it’s an enclosed ducted fan, so blades) that is so overcomplicated it’s mind boggling.

400 €

Amazing features:

color screen. On a fan. Why the fuck!!

Remote: I can get onboard with that, but this shit has 6 buttons and 2 rockers. All I need is an on/off/1/2/3 button, a swing, and a cold/hot that is: cold/low/medium/high heat. 3 buttons.

Noisy. My cheapo stand fan from Aldi moves more air and is way more silent.

“Air multiplier technology”… So a Bernoully shroud. Yeah. Revolutionary. Cutting edge.

Swings. Ohhhh, the innovation! Also tilts. Wow!!!

Air filter: O.K. makes sense in a fucking 400€ machine. The again, they go for 25€ at IKEA, and I’m making one, 3D printed, that uses an automotive HEPA cabin filter, 7€, and 4 120 ultra silent 120mm PC fans, 9€/4. And an aliexpress PS/buck converter (undecided)

Dyson replacement filter: 90€. So I can buy an IKEA purifier, and when the filter is clogged, chuck the whole thing, purifier AND filter, 4 times before I replace the Dyson filter.

Etc…

I used to own a Dyson corded vacuum cleaner. The brushes needed replacement. First gripe on a hideously expensive vacuum. Why brushes?? Why!!! I open it up to replace, and the innards were so cheap ass and flimsy it hurt seeing them. screw stubs without reinforcements, plastic clips so flimsy that they broke just by looking at them, self tapping plastic screws (brass threaded inserts cost ME cents.)…

Also, "Look! we are soo cool! Cyclonic particle separation! Like they invented the tech that has been separating sawdust in woodworking shops and sawmills for a century!

And loud. Unnecessarily loud. They make their vacuums loud on purpose, because people associate loud with power.

I now own a 20 yr. old Vorwerk Kobold, made by the same company that makes the Thermomix, an amazing kitchen appliance. Solid, no problems with spares 20 yrs later, silent, HEPA paper bags (bagless are shit, look up vacuum technician opinions on the web) and has great suction (insert sophomoric joke here). SILENT! So silent the dog doesn’t give 2 fucks about it.

That said, Commercial Dyson hand dryers are the only hand dryers I’ll use. Good.

But yeah, they are the Apple of air moving appliances; make people believe they have invented a lot of shit, while they are essentially packagers of that technology, Gouge customers, convince customers that hardware is great (It’s not, and TBH, a lot of Apple’s isn’t either.)

That is another factor, but not always true. If you print in a heat resistant filament that is also food safe (TBH I don’t know of one, but it probably exists), and use it for solids, like fruit bowls, cookie jars, and the like, and is dishwasher safe. It should be fine. The problem is that most people will not make the entire production path food safe. Too much liability for manufacturers, even with food safe materials.

Many youtube 3D printing influencers actually recommend brain dead shit like drying filaments with undisclosed ingredients in ovens or microwaves where they will cook food, and stupid shit like that.

I wonder if this will mean screwed split-half washing machine drums, for example.

One of the most common failure points in washing machines is the drum bearing. Nowadays almost all makes are using drums where the halves of the drum are plastic, welded together, where they used to be screwed together. The welds prevent opening the drum, and make bearing replacement basically impossible. The makes will sell you a replacement of the whole assembly, but it will often cost like 2/3 of a new machine. This means that a bearing failure often results in chucking a machine that used to be repaired for a cost under a 100 € if done professionally, or tens if DIY.

I imagine the “whole assembly” concept will be used as one of the loopholes.

Water resistance does not mean what people think. ISO 22810 says that a 3 bar (30m) water resistant is “Not suitable for showering, bathing, swimming, snorkeling, water related work, fishing, and diving.”

30m. Not. Suitable. for. showering.

Also, most really waterproof watches, 100m+, have small circular metal cases with metal backs that are screwed shut against a gasket. Some, like G-Shocks, have a proportionally thick stainless steel backplate screwed down, but the plate is what? 3 cm. Diagonal?

Doing so on a thin rectangular device with a reasonable cost is near impossible, too much flex.

It can be, but is a hassle. There are food safe filaments, there are filaments that “should be” safe, like unmodified PETG, but the issue is to make all parts that are in contact with the filament food safe; extruder gears, Bowden tubes and other guides, hot ends, etc…

I imagine that it would be a hassle for parts suppliers to certify the bajillion variations of these parts as food safe.
