If I have a USB powered device, could I leave it plugged into a portable power bank (like the kind you charge your phone with) as a power outage backup?

Basically as the title says. We have semi frequent power outages where I live. The noise machine in my daughter's room goes out and wakes her up. If I were to buy a USB powered one, plug it into a power bank like one of those 10000ma ones you get for charging cell phones, would it have continuous power. Basically like a cheap...

Since you didn't explain why... Using a normal power bank as an UPS is a bad idea because lithium batteries have a limited amount cycles it can charge and discharge. With a power bank the power has to flow from the charger into the battery then out to the load which eats up those cycles. An UPS is a little more clever as the power goes straight to the load via a capacitor bank and a mosfet bypassing the battery. When the source power is cut the UPS runs off of the capacitors for the milliseconds it takes for the mosfet to switch the load over to the battery. This vastly extends the life of the battery and reduces the risks of fire and toxic fumes from being released.

I personally use an APC pro 1500 and it will run my (admittedly large) network for an hour. If your router and modem are around 50 watts you could probably get about two hours.

If you need anything longer than that you should look at solar generators that have an UPS mode like from what bluetti or ecoflow offers as they are a significantly better value than a purpose built high capacity UPS with the added benefits of being able to hook up portable solar panels to extend the run time even further.

I think the safe option would be to use a smart UPS and Network UPS Tools to shutdown the LLM virtual machine when it's running on battery. I do something similar with my NAS as it's running on an older dell R510 so when the UPS goes onto battery it'll safely shut down that whole machine to extend how long my networking gear will stay powered.

I made a thing! (Bluetooth speaker modeled from scratch) ( lemmy.world )

No banana for scale, but let's say that it's not too big and not too small. The dimensions are 295mm tall, 270mm wide, and 240mm deep. If I had to do it again, I would be tempted to go a bit wider and touch less deep. It's probably better to be large in one of these dimensions as opposed to both of them....

Did you do anything to increase the density of the cabinet for better acoustics? I know other 3D printed designs have you fill the empty space with concrete. Also if you ever design more speakers you should try out a paraflex design, it's an open source style of speaker that emits a cardioid dispersion pattern on the low frequencies which makes it possible to aim those frequencies without involving a DSP and math. Unfortunately their main group is on Facebook though https://www.facebook.com/groups/bassaz/

Ultraviolet would be a terrible idea as UV-A and UV-B can cause skin cancer over prolonged exposure and UV-C will straight up burn your eyes and skin.

I work for a railroad and also own a Tesla. FSD doesn't actually know what a train is at all. If you watch the visualization while in FSD you'll see trains as a long string of semi trucks and it sees the crossing arms as flashing red stop lights (ie treat like stop sign).

You999 ,

So many long distance delivery trucks take the same route across the country. Why don't we just string them all together, then have one big-ass truck engine in the front pulling it all? And to save on how big the motor needs to be, we'll have steel on steel contact to reduce friction. Whoops, you've got a train all of a sudden. 😅

Get out of here with your crazy ideas...

Would the recompiled games effect how ACE works in some games? I'd assume since the machine code is different the exploits used to trick the pointers would be different.

Quality of service, networking term for rate limiting. Essentially whatever the QOS is set to is the maximum speed you will see.

Because proton put themselves into this position by making false advertising claims. Let's not forget this isn't the first time proton has given away the IP of an individual and last time was even worse because proton at the time was directly advertising they kept no IP logs which they had to quietly remove after giving the Swiss feds the IP.

HDMI stream live processing?

I’m getting tired of the extremely loud ads on that don’t seem to be subject to the old TV broadcasting laws that prevent them from being blasted 10db louder than the actual content. Wondering if there’s stuff out there that would let me take the hdmi stream from my Apple TV or other streaming source, and do ad detection...

You999 ,

I think you are over complicating things. Just get an HDMI audio extractor (HDCP compliant), feed the audio into an audio compressor/limitor, then you can run the audio into your speakers or buy an HDMI audio injector to feed back into your TV.

Audio compressors do not compress all of your audio. Please refer to the graph in my original comment.

To be fair, Microsoft only bought and killed off the phone division. The rest of Nokia is still around including their R&D department bell labs. You know the same bell labs that's developed some little know inventions like C and C++, solar panels, the transistor, and UNIX...

Why would you need to carry the tools when they breakdown half as often?

If you look at the statistics other than lightning which is skewed because it includes bulb failures, the top failures aren't really stuff you want to be doing on the side of the road.

And Amtrak doesn’t have anti air weapons

Amtrak can pull your own private rail car. Nothing says that car couldn't be the US's navy's armored caboose which may or may not actually have anti air weapons (classified)

In the US pretty much all our ISPs use dynamic IPs by default and charge extra for static IPs. The lease time on the dynamic IP varies dramatically from ISP to ISP.

ZFS is amazing but i wish it's support for flash was better. I'm not sure if ZFS will ever be able to fully utilize flash since ZFS was designed around spinning disks and the pitfalls they provide. Maybe at some point F2FS will catch on...

ETX4 was released in 2006 and BTRFS was released in 2007.

Imo manufacturers need to do the opposite and release more concept cars. Some of the coolest looking cars you can never own. Just look at these masterpieces

All they had to do was use a SoC with a NPU and they could of gotten away with this scam.

Which polestar?

The polestar 1 is a hybrid (discontinued)

Polestar 2 charges 20% to 80% in 28 minutes using LGES or CATL batteries depending on spec

Polestar 3 (unreleased) charges 20% to 80% in 30 minutes using LNMC batteries

Polestar 4 (unreleased) charges 20% to 80% in 30 minutes using LNMC batteries

Polestar 5 (unreleased) is still in development

The part about not suing tesla over patent infringement was the true poison pill and why no one took them up on it. Ford has over 79000 patents alone and that's just one auto manufacture.

If it's a business trip where time matters where you can't afford to loose 25 minutes every few hours, why are you driving instead of flying?

You999 ,

But it's still going to be fast (and cheaper with wages factored in) to fly while using one of the countless 'last mile transportation' options available when the distance is greater than an EVs range while you can't afford to loose time to charging. The only exceptions I see is those jobs who need tools/supplies on site in which case you are almost definitely taking a fleet vehicle and this whole problem is moop.

You999 ,

Your thesis is fundamentally flawed though because you are taking your situation and extrapolating to the public as a whole. While I'll agree the market for new EVs is stupid right now the used market is far from. I say that writing this from my 22' model 3 I paid 18k for used. And that price wasn't a fluke.

I'd also like to add the last mile transportation I was referring to isn't public transport or some ride share app but the industry of van drivers who specialize in business transport. Companies like PTI or Halcon who specialize in getting you from anywhere to anywhere.

The avarage used car loan in the United States is 26k. That price is not "out of reach for the vast majority of people buying used cars".
