Hell yeah, some DIY Perks on lemmy.
Great quality video as always, even though the setup might be cumbersome to add peripherals in the long term.
But still interesting !
-
Wireless power sounds like and RFI nightmare. It will never match the efficiency of a cable either.
-
Efficiency and outright performance isn't always a priority.
A lan cable outperforms a wireless Internet connection in every way, yet most people just use WiFi
-
I doubt anyone is under the impression that it is going to be as efficient as direct power. At least no one paying attention.
Edit: The downvotes lead me to believe a not insignificant number of people don’t understand how energy works.
-
Downvotes be damned: you’re right, imo. A wire just has less to worry about, and I’m sure most people would think the same. Most people.

The downvotes lead me to believe a not insignificant number of people don’t understand how energy works.
The number of people electrocuting themselves doing stupid stuff leads me to believe this, but these downvotes help solidify that lol

This method uses magnetic resonant coupling (vs inductive which is how wireless charging works on your phone). The difference is the transmitter and receiver are both tuned LC circuits that operate at their resonant frequency, which is why this works over the impressive range shown in the video. It would have efficiencies around 80% mark based on what I could find. But yeah for RFI, this would definitely be worse than something like normal Qi charging, which operates in the 100s of KHz, while this operates in the MHz. But I think the manufacturers page says this is FCC certified? So might be not too bad.
-
FCC emission requirements are very lax below 30MHz, so something can pass FCC part 15 yet still jam the entire HF band.

My speakers at home hum due to my Logitech Powerplay Matt, even with a ground loop isolator. It sucks. I was kinda surprised that it wasn't an issue with this setup.
-
I was actually surprised the Bluetooth keyboard and mouse still worked.
-
-
Math, since it has a 10 watt minimum power draw, that would mean it would use 7.5 kilowatts per month just to have it turned on. Now at least where I live, that's $1.11 extra.
-
Math remembers to carry the units for kilowatt hours.
That said, I'd pay $1.11/mo just to never have to deal with a cable on my desk again.
-
If it's on solar / battery, then meh. 10 watts is pretty modest.

Nice, enjoy your wireless nightmare.
Once I had a wireless Corsair Keyboard which sometimes received input from someone else's keyboard (it typed entire sentences on my PC). Corsair said this was impossible, yet somehow words appeared on my screen while only my keyboard was linked. A neighbor logged in to something using his email address and password and it appeared into my word document. Like, wtf!
So I love my wires. I have no wifi, no wireless devices (except for my phone and game controllers) and I have no interference issues with anything (and I have a music studio in my living room with loads of synths).
Just do some proper cable management. It's really fun to do and gives a clean look.
-
Wireless peripherals and any wireless data transfer protocols are completely irrelevant to the content of this video, which is centred around wireless power transfer.
Also wireless peripherals are pretty great, not sure what you're on about.
-
Wireless mouse (with low latency) is one of the best hardware purchases I've ever made. Wireless speakers and screen seems a bit unnecessary though but damn cool that he made it all work

Corsair
I believe I found the problem.

What I'd like to know here is if this setup is continuously drawing maximum power or if the power usage only goes up when a device is within the magnetic grid.
-
it does say on the site for the device that it draws 100W, but in the video he says that there is a 10W minimum draw, so i'm assuming it goes up from there
-
The power draw will go up when a device is drawing power from it, but there will be base/idle draw of course as well.
-
And what their power efficiency is. Last time I checked they were at 60% but I'm wildly outdated on these things.
-
-
I think he releases most of them if you wanna make it yourselve
-
Can I buy this yet
-
No.
A developer kit is available, but only for R&D teams: https://www.etherdyne.net/evalkit
-
Its r&d kits only but send em an email and they will probably sell u one
-
-
Cool..... I'll stick with my wires that work every time and don't have latency, batteries, and connection problems thanks.
-
Batteries and latency? Try watching the video before typing out such ignorant and snide remarks
-
Yet another person commenting without having watched the video.

We coulda had an entirely wireless energy grid back in Tesla's day if it wasn't for capitalists who didn't see a way to profit from it.
-
it also would have very publically been a huge failure. Tesla tended to ignore the science when he didn't like it. It could not have possibly worked
-
We, today, understand how to power something wirelessly. The problem is it's horribly inefficient.
-
No, they saw a way of profiting from it not happening..

Why is this a video and not an article? Makes me think it's just bullshit
-
It's a YouTube channel that does high quality DIY projects, and explains the reasons behind the choices made.
Why would this be an article as opposed to, y'know, a video? His job is to make YouTube videos.
I don't understand this obsession some on Lemmy have with shitting on hard-working creative types when they make something in video form rather than creating a blog and publishing articles.
-
It's an interesting video, you can see the sizes and form factor of the recievers this way much better. You can still skip the parts you are not interested in.
The quick start guide from the link in the description if you just want to read numbers: https://static1.squarespace.com/static/669856991b982007b8a6a788/t/67af70bd5fc318472e2f9f1a/1739550910959/Evaluation+Kit+-+Quick+Start+Guide.pdf
-
Did you even watch the video? It's a well-produced piece of content from a pretty well-known individual
-
Because it is bullshit lol.
Wireless efficiency is around 70%-75% max with something like that; EMF and RMF issues abound in any configuration without shielding, which this one has none of. I am surprised anything works.
I don't know about the rest of you, but I'm not willing to pay a 30% higher electrical bill for something like this.
-
It wouldn't be a 30% higher electrical bill overall. It would be 30% more for whatever power you're using for this specific device, which, if it's ordinarily 10W while in sleep and an average 100W while in use, and you use it 50 hours per week, or 215 hours per month, that's a baseline power usage of 21500 watt hours in use and 5050 watt hours from idle/sleep/suspend. Or a total of 26550 watt hours, or 26.5 kWh. At 20 cents per kWh, you're talking about $5.30 per month in electricity for the computer. A 30% increase would be an extra $1.60 per month.
-
I'd only consider it if I had the first world problem of overly efficient solar panels.
