ShadowRam ,

You could say the same about C and D batteries too.

They're all 1.5V

ShadowRam ,

Yeah, I don't see it any different from a person that says

"I want to be called Micheal, not Mike"

ShadowRam ,

Cancer

ShadowRam ,

Interesting idea,

But search sites currently can't find anything in lemmy.

So how will they link to this?

ShadowRam , (edited )

What sucks is that us hobbist's can't get FPV, motors, ESC's, or batteries at reasonable prices (if at all)

The reality of it, is this is short lived.

Anti-Air meant for small drones like this is coming and soon.

And it will shut these down quickly.

ShadowRam ,

Nah, lasers too big. It would be a simple birdshot shotgun. Its detection and aiming.

When they are high up, they can be hard to spot and hear.
But a pair of sensitive mic's and a camera designed to look for them could easily be paired with some AR glasses.

ShadowRam ,

Yeah, have you seen the size of those? Those are chem lasers in order to get the wattage needed to destroy something.

Plus you need the electronics/mechanics to track the device perfectly to keep the laser on target in order for it to do damage.

All completely unnecessary to drop a small drone out of the sky.

ShadowRam , (edited )

Yeah, that isn't going to work, because either

or

  1. Your countries existing laws give too much voting power to a minority

UK Trial: Pornhub's Chatbot Halts Millions from Accessing Child Abuse Content (www.wired.com)

A trial program conducted by Pornhub in collaboration with UK-based child protection organizations aimed to deter users from searching for child abuse material (CSAM) on its website. Whenever CSAM-related terms were searched, a warning message and a chatbot appeared, directing users to support services. The trial reported a...

ShadowRam ,

hahaha... it saddens me that only those >30yrs old may get this.

ShadowRam , (edited )

a fine in that amount would “crush most small businesses.”

Like it should... you dingbat...

Why do these idiots think they need to "save the businesses!"...

You want your economy to do well? Then make fair laws that attract educated people instead of pushing them away,
and provide a good infrastructure.

Businesses will then look after themselves fine.

ShadowRam ,

You can't use natural gas hydrogen for a fuel cell.

They can't remove enough sulphur from it, and even a trace amount will destroy the fuel cell.

ShadowRam ,

Nope those all contain trace hydrogen sulfide.

ShadowRam ,

My point is simple.

Hydrogen derived from natural gas can not be used in fuel cells. Only hydrolysis hydrogen is viable.
It is one of 'many' reasons why hydrogen fuel will never be a thing.

  • Along with Hydrogen seeping through everything
  • Along with Hydrogen embrittlement

The energy efficiency loss to convert Solar/Wind/Nuc -> Hydrogen -> Mechanical or Solar/Wind/Nuc -> Hydrogen -> Electrical -> Mechanical

Will never be cost effective compared to Solar/Wind/Nuc -> Electrical(batt) -> Mechanical

Hydrogen has been known to man for a 1000 years, and yet
Gobal International WARS have been fought in the past century along with massive geopolitical maneuvering and trillions upon trillions of $$$ spent on the energy sector.

Do you really thing we'd be spending the $$$ we do for deep sea drilling if hydrogen was even close to being a viable resource?

No new technology has been developed that makes hydrogen useful. No. Fuel Cells are not it.
There just isn't enough energy gained by connecting Hydrogen -> Oxygen no matter what process you come up with.

Unless we find a way to fuse hydrogen together, hydrogen is a dead end and always has been.

RIP BOZO

RIH BOZO

ShadowRam ,

I mean,

If Obama's handling of Guantanamo not closing and the drone striking of Somalia and Yemen didn't stop his second term.
I can't see how Gaza's situation will affect Biden's.

Truth is, most of your population doesn't even pay attention to the details of news, unless it's something to do with Kardashian's or Taylor Swift.

How Do You Deal With Thumb Stick Drift? (lemmy.world)

So I like to use Xbox controllers (doesn’t matter if it’s first- or third-party) because I like the layout, it’s just comfortable to me. However I’ve noticed that on all my controllers in the past few years, the left thumb stick will start to “give out” over the course of a couple months. For instance I’ll be...

ShadowRam ,

Hall-Effect is supreme,

But we've been using potentiometers for controller joysticks for 25 years now... and yet it's only been a huge issue lately.

ShadowRam ,

or the toronto sun which is the Canadian equivalent of the Daily Mail

ShadowRam ,

millions of followers

No one gonna question why such sick abusive people gained that kind of popularity to begin with?

ShadowRam ,

Path of Exile,

The true successor to Diablo 2

ShadowRam ,

Law requiring all prices to be in a format of

$ per actual measurement unit and include all applicable taxes.

ShadowRam ,

Right, but he could get the ball rolling by getting someone in congress he knows to start a bill for the idea.

If Repub's shoot it down, then he's got more ammo in his ads

ShadowRam ,

Yeah, and in the UK I noticed that tax is included on the listed price as well. So again, no surprises for people when they check out, and don't need to do the math to account for the extra tax.

ShadowRam ,

Start with SNAP CIRCUITS toys. Even if your an adult, these are a start.

Then upgrade to a ELEGOO UNO Electronics kit off Amazon.

It'll give you the basics of powering stuff, and then basics of signals.

Some kind of RC Car, Multicopter, Self built 3D Printer hobby will also help get you started.

ShadowRam ,

Idiot does idiot things.

The world ignores him.

ShadowRam ,

What fake video?

Where's the god damn video?

ShadowRam ,

_ directing that frustration at these people as if they’re responsible for it_

Yeah.. their voting policies over the years, they are.

ShadowRam ,

No matter how hard you try.

Bits of that unwashed shell are getting in your food.

ShadowRam ,

The replacing the battery is simply a supply issue.

There is such a demand and so little supply, that if you want to buy just a battery (and not the entire car) you are out of luck. They'll put that battery in a new car and sell it before selling it to you as a replacement.

But that's short term. There are a huge number of battery plants already breaking ground and coming online.

In 2 years or so, the price to replace the battery will be a HELL of a lot lower, and the issue you linked above will be long gone.

ShadowRam ,

government regulation to force companies to begin using a modular system

Yeah, that's fair. But the issue is also similar to cell phones.

Each battery is unique because it needs to fit the unique layout of the vehicle. Not to mention the battery tech is moving so fast, that the chemistry of the battery itself is changing every few years.

I suspect China's approach to a vehicle where you hot-swap the batteries instead of charging will be the way it goes. Someone will do it, it will be most $$$ efficient and therefore profitable, and then it will force them all to adopt the same approach.

ShadowRam ,

I can now finally solder things easier.

Drink my coffee while gaming.

Use Push to Talk a lot more while gaming.

Hold the ladder, brace, and hold a nail and hammer all at the same time.

ShadowRam ,

Meh. I hate it.

I think society should be moving towards buildings having a dedicated DC source.
International Standardize on a DC wall plug.

Each device can step it down easily/efficiently with little electronics to their own needs.

ShadowRam ,

No, it's got nothing to do with power over ethernet.

It's simply having only one high power rectifier at the breaker box.

And removing all those rectifiers from every device in the house.

We don't need AC in the home anymore. Every device is now using DC, and any other device will still work with DC.
The only thing really left are motors, but even those are going brushless and we can chop half of the inverter out of the equation of those as well.

And every device won't even need smart electronics for PD either.

It would also solve the North America 60Hz and EU 50Hz issue, where the AC coming in doesn't matter. We all standardize on a DC output.

And when people want to add alternative power (Solar/Wind/etc), it's a HELL of a lot easier to just push the DC into the existing system without having to worry about frequency matching.

ShadowRam ,

_ I don’t think USB C PD could handle a hairdryer though_

Of course it wouldn't. The idea would be get rid of USB-C and PD completely.

You'd have 110VDC@15A available for your hairdryer. Heating coils don't care if it's AC or DC, and the blower fan would be a brushless fan.

You're compressors for AC or fridge would be freq drives, which are cheaper because they could drop the rectifier circuit, and highly efficient.

The only real concern about having DC in the home as standard is the safety aspect of DC doesn't let go if you get shocked.

But that is already being worked on in general as many homes have high-voltage DC circuits from solar panels.

ShadowRam ,

Yeah, but frequency drives/inverters were still pretty pricy things back then to for high powered motors for compressors/blowers/etc.

But the cost and efficiency of those things have dropped SIGNIFICANTLY in the past decade..

ShadowRam ,

PWM DC to DC dropping voltage to what you need is easy/cheep.

So instead of a big transformer + rectifier that each device has now, it would be a much smaller/cheaper step down at like 99.8% efficiency

ShadowRam ,

again, simpler and cheaper electronics for everything

ShadowRam ,

powerful DC-DC

No, are you not aware how these work?

A step down DC-DC is nothing compared to a transformer rectifier or PD electronics with communication with a USB-C.

ShadowRam ,

What?

Most vaccums are brushless, where they are already converting the AC to DC internally. Your vacuums would be cheaper.

Where would I recharge batteries for my lawn care equipment?

again what? The same way? Your charger is converting AC to DC. You could skip that step.

All of these appliances would work better/cheaper with a 110VDC@15A source.

ShadowRam ,

Well, I mean if you don't understand power electronics I don't see how you can make that statement.

ShadowRam ,

No, AC requires large heavy transformers and then rectifying.

DC dropping down to a lower DC is way easier and more efficient.

ShadowRam ,

_ It wants 3.3V, or 5V, or 12V, or 48V, or 18.7V,

Exactly

That's why if you had a 110VDC supply at the wall, you do a simple PWM step-down to the required voltage in every device.

LOADS cheaper/efficient than any USB-C PD circuit...

Saves on transformers, saves on dozens of USB PD wall outlets, saves on communication needed to communicate the PD required between each device and every USB PD wall outlet.

Much cheaper. More efficient.

If only the wall was 100VDC instead of AC

ShadowRam ,

You wouldn't have to.

Every device instead of having an expensive PD communication device in it, would have an even cheaper PWM DC Step-down.

No communication needed.

Each device would just draw what it needs to.

ShadowRam ,

Stuff with motors are, like air con and refrigerators. Those are better left on AC.

No. Trend is they are all showing up with frequency drives. Of which those inverters are rectifying to DC before making their own AC.
Efficiency gains are massive of a frequency drive , hence why they are doing it.
Would be even better if they could drop the first rectifying circuit and just use the inverter portion only.

You lose very little by rectifying AC

You lose a lot actually in all the small cheap rectifiers that are in every device in the house.

Where a single purpose designed FET rectifier that is built for efficiency at the breaker would be drastically better.

4,6,7,10

I don't know. I know I played 9 in its entirety, but it is completely un-rememberable.

But yeah, 100% lets get back to the turn-based formula it was meant to be.
Bonus if we could go back to a 5-team instead of a 3-team

ShadowRam ,

yeah, just because you're not used to it, doesn't make 24hz good.

That's like saying modern animation is garbage and we should stick to stop-motion animation.
