Wireless power sounds like and RFI nightmare. It will never match the efficiency of a cable either.
True Wireless Power is FINALLY here (building a TRULY wire-free desk setup)

I doubt anyone is under the impression that it is going to be as efficient as direct power. At least no one paying attention.

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
Ek-Hou-Van-Braai@piefed.social 2 months ago
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
Ghoelian@lemmy.dbzer0.com 2 months ago
Sure, but I’m not paying for every byte sent overy network, while I am paying for every kWh I use.
That’s all beside the point though, this is just a fun diy project so who cares really.

I was actually surprised the Bluetooth keyboard and mouse still worked.
scarilog@lemmy.world 2 months ago
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.
cmnybo@discuss.tchncs.de 2 months ago
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.

This better be electroboom
davidgro@lemmy.world 2 months ago
It’s not - this dude doesn’t zap himself even once.
It’s a good video though, showing how he integrated everything.
LordWiggle@lemmy.world 2 months ago
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.
CybranM@feddit.nu 2 months ago
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
BlameTheAntifa@lemmy.world 2 months ago
Corsair
I believe I found the problem.
seliaste@lemmy.blahaj.zone 2 months ago
Do you remember the exact model? I’m interested in looking into it
LordWiggle@lemmy.world 2 months ago
Took some digging in my mailbox, but I found it: the Corsair K57 RGB wireless qwerty keyboard.
Burn1ngBull3t@lemmy.world 2 months ago
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 !

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.
vrighter@discuss.tchncs.de 2 months ago
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
allidoislietomyself@lemmy.world 2 months ago
Pretty sure I saw a movie where ol’ Nick Tesla cloned Wolverine a bunch of times to fight Batman. If he was able to make clones back in the day I’m sure he could figure out a power grid issue.

- Wireless
- limited range
- horribly inefficient
So, there.
lime@feddit.nu 2 months ago
tesla’s idea was global wireless power. no idea what his efficiency numbers were though.
Tattorack@lemmy.world 2 months ago
We, today, understand how to power something wirelessly. The problem is it’s horribly inefficient.
KeenFlame@feddit.nu 2 months ago
No, they saw a way of profiting from it not happening…
uninvitedguest@lemmy.ca 2 months ago
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.
lime@feddit.nu 2 months ago
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
MangoPenguin@lemmy.blahaj.zone 2 months ago
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.
Lemminary@lemmy.world 2 months ago
And what their power efficiency is. Last time I checked they were at 60% but I’m wildly outdated on these things.

Can I buy this yet

No.
A developer kit is available, but only for R&D teams: www.etherdyne.net/evalkit

muntedcrocodile@lemm.ee 2 months ago
Its r&d kits only but send em an email and they will probably sell u one
shortwavesurfer@lemmy.zip 2 months ago
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.
RvTV95XBeo@sh.itjust.works 2 months ago
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.
BagOfHeavyStones@piefed.social 2 months ago
If it's on solar / battery, then meh. 10 watts is pretty modest.
chronicledmonocle@lemmy.world 2 months ago
Cool… I’ll stick with my wires that work every time and don’t have latency, batteries, and connection problems thanks.
CybranM@feddit.nu 2 months ago
Batteries and latency? Try watching the video before typing out such ignorant and snide remarks
scarilog@lemmy.world 2 months ago
Yet another person commenting without having watched the video.

Buy wireless items, open it up, wires inside. Cat staring at OP as in a “What is this shit” kinda way
