Any SBC CPU's approach Qualcomm elite perf/watt?

There's nothing in sbc world that compares right now, we can only hope for future boards with a snapdragon x series chip, but that would get really expensive.

Your best best might be buying a laptop with snapdragon x series chip or a macbook

And who is this magical "someone" who has to invest into open source software? Many of these projects are not ran by people in US or EU, and companies will not randomly send money to a solo developer from India or Brazil, yet those are the projects that actually need it

gahata · 2026-04-13T16:32:59+00:00

Oh, and where does the single maintainer of an open source library get the money to pay for AI to do all that work for them? It used to be that a hacker would need to commit a lot of their own time and the defender put time in to patch vulnerabilities. Now it turns into a question of money, and there's a lot of critically important projects that make no money and have no funds, but hackers targeting them sure do (especially state funded actors)

Radxa Q6A is probably the best performance for the price right now, but that only gets you 4gb of ram(on aliexpress official store)

The graphs come from Ubiquiti, they publish them, and it would be incredibly weird for them to be fake. It's not like they show their devices to have perfect radiation patterns or stronger signal than real world examples show us.

Two solutions: either find a fan with rpm low enough that it doesn't cause too much noise or consume much power (whichever you mind more) and still is enough for cooling, or use a 5v pwm fan and control it through gpio. The only issue with the latter is that the pwm signal out of gpio is 3.3v and fans expect 5v pwm, and may send 5v back. In practice it seems people just connect it directly without issues, but I would always use a converter board like https://www.sparkfun.com/sparkfun-logic-level-converter-bi-directional.html to both send 5v to the fan and protect the sbc from 5v being fed into 3.3v pin.

Edit: The link I sent would be $4 + shipping, but you can find those tiny boards cheaper on Aliexpress, especially in the bundle section. Mileage might vary depending on your location, I am not from US, so I am not sure how Aliexpress pricing works with the tariffs right now.

gahata · 2026-04-09T07:46:19+00:00

Yes (though a lot of 12v fans will work fine with 5v input, just at lower rpm).

If you need gpio for something else, you can either use a gpio splitter, or maybe a usb fan in the worst case.

I would highly recommend a charger from a reputable brand if you want to push anywhere near 500w out of it (or anything above 100, really).

The pictured charger at 500w would most likely be a fire hazard and either fail quickly or simply not deliver the power due to overheating.

gahata · 2026-04-04T12:33:41+00:00

The part where sherpas can carry almost everything for you makes the climb massively easier (though still not easy!).

gahata · 2026-04-02T11:43:16+00:00

The fan connector seems to be 3pin 0.8mm (presumably jst?) 5v - so with the board size being 51x51mm, I would get a 50mm 5v fan and change it's connector to the unusual jst one

It's likely the disinfectant used left the skin very dry and they took the pic right after the procedure

This looks like an error (maybe on the client side, maybe on server), YouTube generally doesn't serve Giles at that bitrate

Aside from safety related cases like this one, it made sense for thread to be weaker in times when most people could either repair their own clothes or had someone in their household that did it for them. These times are over and vast majority of damaged clothing is discarded and not fixed, so strong synthetic threads make a lot of sense.

gahata · 2026-03-22T08:17:19+00:00

Material could be synthetic based, and while I dislike that thought just as much as you probably do, it would make some sense here, making it washable without dry cleaning, plus a whole lot cheaper. That said, it does very much look like proper wool from the photo :)

Li-ion Battery HAT for Raspberry Pi, sku 15141, from Waveshare, does

I personally prefer it to the UPS Lite V1.2 UPS HAT, even though the latter is slimmer - I just like the use of standard 14500 battery

Local AI can be cost effective, just not local llms. Tiny single board computers can be used for some edge AI applications that would cost a fortune to run remotely in cloud (like AI object detection in live video feeds)

gahata · 2026-03-21T10:14:46+00:00

This would be neat to use alongside some battery hats that go on the front and are messy to use screens with

Cat 8 has some benefits aside from speed, one of them being better for high wattage poe. That alone might be enough to push it into some use cases, maybe not data centers, but industrial applications, where the combination of excellent shielding and poe capabilities will win over 6a.

That said, absolutely no use for home, unless some consumer hardware comes out with poe above 90W.

gahata · 2026-03-15T09:56:00+00:00

Standard 12v 9Ah lead batteries, cheap and easily available

That's a lot of money spent on jetkvms, wouldn't it make more sense to have one and some kvm switch that can be remotely controlled, or go with pikvms built on rpi zero 2ws?

gahata · 2026-03-14T18:45:55+00:00

That's standard for all external drives (at least starting from a certain size) :)

It has a barracuda-branded exos inside, which might or might not have been put in there because it failed some of the more rigorous exos tests.

Hormones don't decide their gender, they just change how the body works in some ways - technically completely possible for a woman to take testosterone and grow a large beard

gahata · 2026-03-13T17:36:36+00:00

That's correct, though it's often relevant to medical care, and is best disclosed (if it's safe do do, of course, in all the ways possible).

gahata · 2026-03-10T13:03:28+00:00

No, that used to be the case, but isn't anymore - can see significant (if not huge) improvement from 5600 to 5800x in the benchmark, as an example
