Interesting idea,

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

So how will they link to this?
⁨Comment⁩ on ⁨Killer drones pioneered in Ukraine are the weapons of the future⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
Yeah, have you seen the size of those? Those are chem lasers in order to get the wattage needed to destroy something.
⁨Comment⁩ on ⁨Killer drones pioneered in Ukraine are the weapons of the future⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
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.

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.

⁨Comment⁩ on ⁨Advice on first 3D printer⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
No matter what printer you get,

I recommend avoiding any printer designed to move the bed in the Y-Axis.

It's an old design prior to CoreXY and it isn't needed anymore, and has a lot of cons compared with no pros.
⁨Comment⁩ on ⁨How do I learn about DIY modern electronics?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
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.

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, hence why they are doing it.

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.

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.

_ 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
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
No, AC requires large heavy transformers and then rectifying.

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

Well, I mean if you don't understand electronics I don't see how you can make that statement.
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
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.
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
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.
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
again, simpler and cheaper electronics for everything

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
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
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..

_ 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.
⁨Comment⁩ on ⁨USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!⁩ ⁨⁨9⁩ ⁨months⁩ ago⁩:
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.

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.

Yeah, I've been 'just printing' now for about 5 years straight.
I don't even look at the printer prior to sending it a print wirelessly. I just hit print, and it works.

Always sticks to bed, no failures.

It's about knowing the mechanic's and failure points and knowing how to maintain it properly.

⁨Comment⁩ on ⁨What operating system and tools should a beginner use to learn programming?⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:
Depends, What kind of programming are you interested in and what do you want to do with it?
- Low level microcontrollers (PLC's, Robotics, Control systems, ROS, Automation, etc)
- Higher level systems (Software Engineering, Enterprise Software, Networking, etc)
- UX programming (Graphical User interfaces, human-machine interfacing, websites, etc)
- Video Game Programming
- AI Programming, Machine Learning, Prompt Engineering, maybe Data Processing, Vision systems, Simulations, etc
All depends on what you want to do with your programming. You'll need to narrow down and focus on what you hope to do with it.
