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.
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 !
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.
Corsair
I believe I found the problem.
Do you remember the exact model? I'm interested in looking into it
Took some digging in my mailbox, but I found it: the Corsair K57 RGB wireless qwerty keyboard.
Thank you so much :D

Wireless power sounds like and RFI nightmare. It will never match the efficiency of a cable either.
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.
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
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 could argue that WiFi uses more power than LAN cables, so you're paying to use WiFi
The important thing is if it's worth the price, paying 5$ extra per month in power might be worth it for a LOT of people
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.

The number of people electrocuting themselves doing stupid stuff leads me to believe this, but these downvotes help solidify that lol
