I find spending a bit more on batteries goes along way. Although the nominal voltage and size may be the same, better batteries have lower internal resistance, ie provide the same current with less voltage sag. This prevent the low bat detection from tripping prematurely.
Batteries have one advantage over over supplies: extremely low noise. Even an good LDO will bump up the noise floor, and a cheap lcsc part will do so too. Plus you’s want a reasonably low dropout and quiescent current, which also increases price. Maybe 10ct in volume is reasonable for such a part - and yes, that will absolutely eat the margin
Nobody can buy land in china, it is only leased from the government for up to 70 years for residential usage (less for other purposes). Calling the tofu-dreg building on top of this “owning a home” is disingenuous at best and deceitful at worst. Why do people buy homes anyway instead of renting? Because all other options to invest are even worse and it is literally their only option.
I hope you don’t tolerate how mega corps “sell” you shit like digital media or IoT devices only to later change the terms of sale and steal it back from you, because you never really owned it. Don’t tolerate the same shit if a government does it to you.
None of the high end chips were made in Chinese fabs, and the device barely qualifies as a “laptop” besides the form factor. For some bizarre reason they used a USB5744 USB 3.2 5Gb/s hub chip, which tells me the following:
Unless We get better close up tear down photos, this devices primary purpose is propaganda
Good advertising on your side
Seen your meme during my lunch break doom scrolling on another site. Happy to see you are here on lemmy too!
There is a UFS-II specification and even a PCIe version specifically for micro SD cards. It was all planned out, and it would have been trivial to tell consumers: “Yo need card with more contacts as shown in picture”. But no, the biggest manufacturer of flash storage is samsung, and they decided they’d rather sell higher storage capacity phones as a premium. Easy to do when you’re the second biggest manufacturer of of phones and apple already paved the way.
Nice list. I chuckled at the fact that the bitcoin section does not recommend bitcoin :) We’re also here on lemmy, if you ever need help or just want to say hi
Fascinating. Thanks for taking the time to type it out
You are probably right, and I hate it.
LPCAMM seems more useful overall as a product.
Only if you need 2-4 sticks, otherwise they take up too much PCB space. Look at servers and how a good chunk of their volume is filled with dozens of sticks. You cant simply lay them down flat.
Man this job posting is worse then all the garbage that companies put out. There will be very few people who tolerate KYC for non-paying volunteer internet janny job - and those who do should probably never be mods. Good luck tho, you’ll need it.
LPCAMM may have better specs, but DIMM requires a smaller area on the PCB and can make better use of the vertical space.
I’m not suggesting to pay one euro each month, I’m suggesting that you treat your lemmy instance as a 12 euro per year subscription. Compared to literally every other service it is basically free.
It’s not even expensive. A single euro monthly per user is more then enough to keep instances running
A slight heating is perfectly normal and nothing to worry about. A microwave is fine tuned to heat food, or more precisely the water within. Other materials such as the glass on the back of the phone also absorb some energy, but only a tiny fraction.
People joke about this all the time, and I here the sarcasm in your comment, but technology has come far since the iphone 6 or 7.
Most high end phones have wireless charging build it. Between the receiver coil and the rest of the phone is a thin sheet of ferrite material to prevent the electromagnetic field from getting to the sensitive electronics. Battery technology has also improved a lot, so much that even relatively cheap phones like the Realme GT Neo 5 charge at 150W!
From the technical perspective the limit is the cable and connector, because there would be too much losses that heat up the cable to dangerous levels and rapidly degrade the contact area in the connectors. Manufacturers don’t want to deal with this security risk, not the increased RMA rates within the mandated guarantee period, so they artificially limit the charging rate.
Thing is: You absolutely can charge at higher speeds if you bypass the cable altogether! A microwave outputs usually somewhere between 150W-1000W, so stick to the lower end to be on the safe side. The screen of the phone must face down, because the charging coil is placed on the back. You also must prevent overcharging by setting the timer correctly: If your phone battery has 15Wh capacity, and you are charging with 150W, you must at most charge for 1/10 of an hour, or 6 minutes (less if you are just topping up your phone).
One final note: fast charging does put increased wear on the battery, so I only recommend to use it when you need it, for example when you need to make a flight and are already running late.
I am aware of the basic arguments behind inflation/deflation, and neither is good in excess.
Typically central banks targets inflation of 2% these days, but we all know the real inflation for necessities is far higher (>4%). Inflation disproportionately affects the poorer - rich people have the fast majority of their wealth “stored” in stocks or real estate, which rise in valuation as people rush into these markets to protect the little they have. I’d argue that inflation rates are artificially pushed far higher then is sustainable, simply because those who decide are the same people who benefit the most.
I consider a low but predictable inflation rate about 1% ideal (0-2% is acceptable short term variation) for the following reasons:
Yes, this idea is not without risks. But the way I see it the forced “we have to improve value by 2% every year” exponential grow can only go on so long before we (humanity) hit the finite limits of this planet.
Fascinating! Thank you for including a picture of the new design, using the ribs to reinforce the surface should improve things a lot with minimal material added.
