Regardless of your skill, some devices are designed to be throwaway

Some are assembled with glue or welding
Some are completely encased in plastic by potting or overmolding
Some components, like ICs in BGA packaging, cannot easily be replaced with common tools
Many manufacturers don't offer repair parts..at any price
Sometimes, manufacturers grind off the identifying information on common parts to make repair and reverse engineering more difficult
Schematics and repair manuals are often completely unavailable, or very expensive
Many products require special tools that are unavailable at any price
Even if you have the skill to build your own tools, software interface documentation is rarely available, and often the interface is obfuscated
I have been building stuff, fixing stuff and reverse engineering stuff for many, many years
Yes, I agree that fixing stuff is a valuable skill that should be taught and not allowed to die
But, much of the fault lies with the manufacturers who aggressively resist any attempt by users to gain control over their devices

This practice should be illegal, we should have the legal right to fix stuff we own if we have the knowledge to do so

Vinnie Cilurzo of Russian River published a homebrew recipe for Pliny the Elder along with a detailed description of how he designed it

Mitch Steele of Stone wrote a book on IPA which included recipes for many of Stone's beers

Craft brewing and homebrewing have a long and interconnected history

Many craft brewers started as homebrewers and many craft breweries own homebrew supply stores and support homebrew clubs

The craft brewers I have visited freely answered any questions I asked

It's the same everywhere

Instead of our current system where work/school starts at 8:00 and we adjust our clocks to compensate for the season, it would make more sense for schools and businesses to adjust their hours based on the season

Agreed

It's hard to imagine any site allowing 1,000,000 bad guesses

It probably varies by site, but methinks anything over 100 or so would trigger a response

Even if the limit was 1000, same outcome

I wonder if an actual prototype has been built

Yes, it's a cool demo..congratulations to a bunch of cool engineers

No, it's not a 3D printed car

At best, it's a crudely 3D printed body shell over traditionally made parts

There is no 3D printing tech available now that can print a ball bearing..or gears..or springs..or a motor

They are just too tiny

I would have to carry a magnifier with me

It's the rules, the bureaucracy and the paperwork

In the 90s, I worked on a project in San Francisco

As I walked around the city, I saw angry rants pasted on various surfaces around town

The ranters were denouncing the "yuppie invasion" and claiming that it was ruining the neighborhood

It seemed to me, that if you replaced every occurrence of the word "yuppie" with the word "nigger", it would have fit perfectly into a KKK rant from the 50s

..in the traditional sales system is not a thing that most people enjoy

Some people falsely believe they are "players" but they still get screwed

Most people are "sheep" and they get screwed faster and harder

I am not a master negotiator..I just want a car at a fair price

I always feel like a lamb in a roomful of tigers when I deal with a traditional car dealer

I'm a really good engineer, and I have many other talents..but cutthroat negotiation is not one of them

I really, really want a better system

The real solution is pure electric

The energy source may be batteries, supercapacitors or hydrogen..or something new??

Hybrids are at best an intermediate solution

The good news is that they advanced the manufacturing experience of electric motors and control electronics for vehicle use ,,and started consumers thinking that gasoline is not the only path

I despise apple. I refer to them as "the distilled essence of evil"

Nice to see them wasting money on a stupid purchase

..of VR that makes writers ignore reality and talk about fantasy as if it really exists

This is an important step toward the answer..but NOT the answer..yet

VR is harder than anybody realizes

Valiantly fighting the good fight against the evil weasels who view our freedom as a threat

He is still a hero to many of us

..any place I worked since 1980

Engineering offices are very close to 100% male
