If you own a 3D printer, there are oftentimes STLs people publish online to shrink the size of the fob. Made my keys much less bulky

Now that’s an idea… I found one for my car, but kind of hate it. I don’t have a 3D printer currently. I did help my cousin’s kid by one and they told me if I ever wanted to print something to let them know, but I have a feeling I’ll need to design my own with some trial and error. I’ve hesitated buying one, because the idea of having a machine to melt plastic in my house seems like a bad idea when it comes to air qua…

Depends on the plastic, but even the most benign ones put out very minor amounts of fumes if YouTube testers are to be believed. Note that fumes in this case just means that they are seeing changes in AQI meters, which is something that can happen with too many people sitting in a room.

If it’s something you worry about, the enclosed models frequently either come with, or can be fitted with a carbon filter, and if you are really worried, you can use dryer vent to get it outside.

With the most popular plastic (PLA) at printing temperatures, there isn’t any data showing toxic byproducts. When you get into things like ABS and resin you have to think more about fumes.

People talking about Chinese manufacturing all being junk are completely stuck in the past.

My grandfather in the 1970s used to complain about crappy Japanese tools. By the 1980s they were world-class. Same is happening with Chinese manufacturing.

There is a joke just about that in Back to the Future (1985)!

> repair is expensive ($1000+ for performance cars, not that much cheaper for Civics) I can almost guarantee the lion's share of this is shop labor, not parts, and pressing a bushing out and back in would be more expensive after accounting for that labor than just swapping the suspension arms. This is often the piece that gets missed in these discussions of "why am I replacing this huge assembly for a tiny part", if…

I’ve moved in to doing my own plumbing, electric, HVAC. Tend to keep new enough cars that they don’t need much, knock on wood. But it’s not uncommon in “making” $500 an hour or more doing electric or HVAC.

In my area, no tradesman is willing to even get out of bed for less than $1000. They have more high dollar work than they know what to do with and some of them don’t even pick up the phone anymore. You have to be made of money or learn how to DIY everything.

IBM

IBM no longer has fabs (spun off as Globalfoundries and later sold), and no longer manufactures PCs (sold to Lenovo?), but it does make mainframes I guess?

I thought GlobalFoundries was AMD's fab division spun off.

Folded into the base is a mechanical backup key, a flat metal blade in a hinged housing. It reads warmer than everything else in the scan. It exists for the moment the battery dies or the RF link fails. Every BYD keyless entry system includes this fallback.

It's simple things like this which incumbent manufacturers need to avoid losing sight of.

I've got a friend whos a master tech/trainer with our state automotive body, and is HV certified etc for dealing with these cars. He's currently got a BYD Shark strewn across his workshop for an autopsy. I have to say I'm super impressed with how heavy duty everything is. The control arms, subframes, etc all look good and don't fit the 'chinese car bad' narrative you always hear. The powertrain components all look to…

In the last few years Chinese manufacturing has reached a very high-level. The reason most people still believe that Chinese-made stuff is poor quality is because they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills. While I reckon some other countries still have specialist manufacturing in key areas that surpasses China, most “common” parts can be…

I find that Chinese manufacturing offers the complete range of quality for every price point. At reasonable prices, the quality meets or exceeds that of other countries. But if you want something cheap and cheaply made, you can find that as well. And at the extreme, you still have counterfeit parts and products.

I guess my intent was not to point out that it has a mechanical key, rather that the description of the key on the webpage was wrong (it is not hinged). The mechanical key fallback pattern is standard across the industry for sure.

It's entirely possible that the BYD key they scanned and the BYD key you possess are of different designs.

Possible, but I doubt it.

Article says key fobs are the same across all their cars and this looks the same as mine for a Sealion 5, there is no hinge for the key you just pull it out.

Likely the article authors just assumed from looking at the scan, if they’d actually tried to remove the key they would have realised their mistake.

Nice. Those are small parts, though. The interesting part is the E-axle. BYD builds a unit with an integrated motor, differential, axle, and wheel hubs. That, plus an electronics box and battery, is the power train. This simplifies vehicles considerably. There are E-axle teardown videos. There's no big secret about how to do this. Copying this is hard for Detroit, because they have a huge investment in "engine plants…

You have some false beliefs about Detroit’s product lines.

Fords mustang mach e is unrelated to the gas one. Totally different platform. It was designed from the ground up as an electric platform. The electric F-150 was a shrewd bet that didn’t pay off, but a pretty defensible decision to try to electrify the most popular vehicle in North America without changing the outside look too much. Under the sheet metal it doesn’t share a lot of drivetrain parts with the gas truck.

Chevy makes full size electric trucks on an all electric platform with three truck/SUV models across three brands. The bolt was cancelled in 2022 with the last one produced in December 2023. They have restarted production of the Bolt for the 2026 model year. The Bolt is also built on a platform designed as electric only. The factory building the Bolt is being tentatively retooled next year to build higher margin cars as a result of Trumps tariffs. I don’t see how any of that has anything to do with appeasing Trump.

Stellantis is its own mess, and they suck at designing all cars regardless of energy source.

BYD only entered the Australian car market in 2022. They are now the 2nd biggest seller after Toyota ( https://www.msn.com/en-au/news/insight/byd-overtakes-rivals-... ).

US manufacturers' niche is half-ton and above trucks. Even mighty Toyota's offering is playing distant #4 in that market with Nissan capitulating after 20 years of trying.

Fun fact: Australia's most popular vehicle has always been utes (aka pickup trucks)

Last year it was the Ford Ranger.
