I’m always surprised how poor engineering gets exposed in products I purchase being an Arizona resident. No, failing at 122F is not acceptable. If your hardware is exposed to outside conditions, it should operate easily below 32F, and well above 140F. Considering that phones can operate below 0F and near 122F, that’s embarrassingly bad. Same thing in vehicles. If you’re driving consistently at interstate speeds, you…

> Too many vehicles fail this, and frankly it’s repulsive for something you buy for 5-6 figures. What's repulsive is the way many people live in AZ. Literal hot take: maybe people living in one of the hottest places on Earth shouldn't expect to have the same consumer experience (without modulating their habits). IMHO, AZ is chock full of human hubris. Pools, fountains, water features, grass lawns, and golf courses. W…

To be fair, we’re all environmental parasites no matter where we are on this heckin planet.

It's a heckin' internet uplink dish, not a mission-critical piece of engineering lives depend on (if Starlink is your only way to call emergency services, you ought to have a radio backup).

I'm not taking about the dish in my comment, I'm talking about Teslas shortcuts. But it doesn't really help if your poor engineering only causes your company to fail due to recall, or gets you shut down for fraud or negligence, or your product is so bad that customers entirely leave your market. That's still not something to champion.

The correct order is:

1) Start a pioneering car company in the 21st century with many incumbent car manufacturers, dealerships and regulations

2) Give business advice on (1)

I dont get the °C vs F one? with 122C youre covered for 122F. 122C = 251.6F and 122F = 50C

The device detects overheating and shuts down orderly. If they planned to shut it down at 122C (which is indeed close to melting the solder) but by mistake made it shut down at 122F (not that much for most electronics), it would be a completely understandable blooper. It doesn't mean that the hardware isn't capable of operating at 122F.

I doubt that everyone on the team missed the fact that electronics get hot outdoors in the summer. Rather, they probably chose to launch a product that breaks when it gets hot, because it's an easy problem to fix later. Now that something is out in the field, they can debug their network, satellites, RF hardware, installation instructions, management applications, and figure out what kind of customers want to buy thi…

This is exactly the whole "agile" vs traditional/waterfall mentality, scooters before motorcars, etc., put into practice. Hardware is hard . > It's also completely possible that the parts simply aren't available Fun fact: they don't make (commercially available) GPUs, NICs, pretty much any PC components rated below 0°F. If you need to design a system which needs to sit in an aircraft in Deadhorse, Alaska, you either…

I wouldn't want to roll the dice when it comes to aircraft

"Hardware is hard", I would say Manufacturing is hard.

Starlink is in beta. The entire purpose of the beta is to find stuff like this. They found something, and I'm sure that the next iteration of this before it goes to mass market will account for it. You're just seeing the system work.

This is not something to find in a beta. This is a built-in feature and operating temperatures are not picked at random (they should not be, at least)

That expensive part is NRE and only making a few tens of them, no production efficiency. With the volumes spacex will be hitting, efficiencies will certainly be found and NRE exceptionally better amortized.

I agree, it wasn't arrogance. Deliberately going forward with something in spite of knowing for certain that it's not fit for purpose is called engineering malfeasance, not arrogance.

> Deliberately going forward with something in spite of knowing for certain that it's not fit for purpose is called engineering malfeasance, not arrogance. An argument can be made for both. Malfeasance in that it was a significant and potentially catastrophic engineering tradeoff due to unknown failure modes, and arrogant in that the decision valued company vision over potential consumer safety risks as well as over…

Selling something you know breaks within a short amount of time in the lifetime of a car and then not wanting to replace it is fraud.
