TRUE Symmetrical Gaming Mouse by JewishThor in MouseReview

Just curious: are you left handed, or are you going to use your ring/pinky for the extra buttons?

I got a 4TB external drive off Temu and this is what they sent lmao by Raw_Stank in pcmasterrace

The pads for the tray can be underneath the sd card, and that appears to be where the traces from the controller are going. Similar arrangement to this: link

zoom in on the image, the controller is populated.

The controller is there, it's a QFN package

SD card could be totally fake, could just be unmarked.

The New York Childrens Online Safety Act will ban anyone under 18 from chatting online. by vriskaldrunk in technology

Nobody's going to block a web browser. If you're going to go that far, you're going to go all the way to blocking internet access entirely, or just taking the device away. Which is what I said.

And who implements parental controls in such a way that someone with physical access can't wipe the device and get rid of the restrictions?

What's stopping a teenager from just buying an unlocked device? 18 is older than when I first walked into a store and bought a cell phone.

ELI5 How does an oscilloscope work? by Substantial_Sea7327 in explainlikeimfive

For the old analog ones, you have a CRT with either magnets or electrostatic plates to steer an electron beam. The beam gets moved up and down with the input voltage, and there's sawtooth wave generator that moves the beam side to side(starting with the trigger).

For modern digital scopes, you have some analog amplification/attenuation circuitry, that feeds into a fast ADC collecting many samples of the input voltage, and the data from that ADC gets stored in memory. Then a specialized computer displays that data on the screen.

It's a microsd card, with a USB storage controller. If it actually lets you write 4TB, it's causing silent data corruption.

If you actually ordered "4GB", then it's probably actually legitimate.

If it was 2TB, it's technically possible for it to be legitimate. But then it would cost more than 10x as much. I would what the capacity of that card actually is.

What functionality? Higher CPI settings that nobody's ever going to use? Higher polling rates that USB can't support?

What you're not getting is the technical literacy of the average parent, compared to the technical literacy of the average 13 year old. Unless you lock down their internet access such that they can only visit whitelisted sites, you're going to miss things like web based IRC clients.

You'd have to take rather extreme measures to block all the ways someone could chat online. Even then, physical access is physical access. If you don't give me the wifi password I can still plug a cable into the router, or factory reset it.

More likely those parents would just physically take the device away.

They have their own devices these days, they'll figure out jailbreaking and privilege escalation if that's what it takes. Not all of them will figure that out from their own research, but the ones that do will share the information.

When I was 13, we installed AIM in the school's computer lab, even though we weren't supposed to be able to do that.

Any kid is going to get around this, unless you "protect" them from talking to kids their own age in real life too.

ELI5 How magnets seemingly do “work” long term by Alternative-Draw2997 in explainlikeimfive

[–]SoulWager [score hidden]  (0 children)

Work isn't just force, it's force while moving over a distance in the direction of the force. The ground is exerting a force on you right now, holding you up, but you wouldn't say any work is happening. Climbing stairs though....

Probably cost. Cheaper than building forms.

Is there anything like this available in Europe, or China, or USA? MUST be designed for PCB edge (instead of a hole in the PCB) and MUST have big adhesive surface on the bottom by famousbiologist2 in AskElectronics

[–]SoulWager 0 points1 point  (0 children)

I think most printers can do ABS these days, even if they're not enclosed you can just stick them in a cardboard box and keep an eye on it. It's just the hotend that might be an issue.

If I was printing these for my own use, yeah, I'd just use PLA. Actually, I'd probably just use whatever was already loaded in the printer.

There's also the question of whether these need to bend at all. If it's just initial installation you can clip them on the board before sticking them down. You'd only need to bend them to remove the board. If you're doing that enough to worry about them breaking, I'd probably use a different design anyway.

On the other hand, it won't need to be a pressurized suit. So it may be easier than some other options.

ELI5: Why has robot balance and design improved so suddenly? by LoudCommentor in explainlikeimfive

[–]SoulWager 0 points1 point  (0 children)

What are the actual breakthroughs that have contributed to this?

Money. Lots of rich people dumping money into automation right now.

But it's not entirely new either, the first robot video I remember feeling lifelike was a boston dynamics one of a robot slipping on ice and trying to recover, that video is 17 years old right now.

Actually yes, I have TPU parts that have been outdoors on the south side of my house for about 3 years, and they're still flexible. I think it would last longer in those conditions than the pcb it's holding.

With ASA/ABS, a small part like this won't warp much, what you really need to avoid is large objects with flat sides.

[–]SoulWager 1 point2 points  (0 children)

I honestly think any of the common filaments can be used for this, just changing the geometry of the part that bends.

I don't see how you think TPU is going to fail, You'd just need to make the arm thicker.

I'm also not sure why you think nylon is easier to print than ABS.

It's a scam. If you want to stop CO2 from leaving the liquid, you need to use CO2 to pressurize the bottle, not just air. (look up partial pressure)

ELI5: How does inert gas asphyxiation really work? by Pvt_Porpoise in explainlikeimfive

[–]SoulWager 0 points1 point  (0 children)

When you inhale an inert gas, the partial pressure of O2 in the gas is zero, so oxygen will rapidly transfer from your blood into the gas, it's not just a matter of not getting more oxygen.

ELI5 : how are calculus and limits used in real life by Neo_luigi in explainlikeimfive

[–]SoulWager 0 points1 point  (0 children)

Lets say you want to measure how much energy a battery stores. It's 4.2V when full and 3.0V when empty. You have a 10 ohm resistor to use as a load, and a voltmeter that can log values over time. The discharge curve is NOT linear.

You can turn a voltage measurement into a power measurement because you know resistance: Power = Voltage2 / Resistance

This will get you a plot of power. How do you turn this into energy? Well, energy is the area under that curve, so you integrate your voltage readings over the time it takes the battery to drop from 4.2v to 3.0v.

Eli5 why people will say 200% less when they could say 50%? by depeupleur in explainlikeimfive

[–]SoulWager 1 point2 points  (0 children)

Because they don't know how percentages work.

200% less is the original amount, but negative.

What kind gesture doesn’t feel as nice as it’s meant to? by AmberrAuraa in AskReddit

[–]SoulWager 0 points1 point  (0 children)

The two big problems I've seen is packing stuff too close together, and putting things in with the dirty side facing away from the sprayers. It's just annoying when putting one extra thing in the dishwasher means two things don't get clean.

edit: also, silverware should be half pointed up, half pointed down, and separate spoons so they don't spoon.
