Does anyone have any real world experience with a giant Qi charging mat? Something that can charge 3-4 devices at a time, no matter where they are slapped down? Iām looking for something around 12 x 24 inches (31x62cm ish)
Damn, are you planning to have an LED screen on your chest?

Haha naa much more mundaneā¦ just want to plop phones down lazily with no regard for positioning

Subdermal phones? Lol

I think that Apple tried something like that but smaller and failed. So now they added magnets to help with alignmentā¦
IMHO, Qi charging is still better than fumbling around looking for a cable. Even if you sometimes have to find the correct location to get it to work.
Wait, are we going to get a wireless charging bed for cyborgs at some point? 
Make a tray with phone sized cut-outs. Each cutout has a Qi charger underneath it.

Someone is clearly smarter than meā¦
Nope, just deal with that kind of thing every day.
I make fixtures and tooling in a machine shop for a big name manufacturer. Alot of my work is about making it bullet-proof simple so the poor idiots canāt screw it up. They will anyway, but I try to slow 'em down abit.

They already have it for birds.
Although I surelly agree with you in principle, I do run away from Qi chargers and smash any that find itself in my residence.
This is solely because I have negative trust in the Qi charger industry:
- Never found a single one which follows standards correctly
- Read way too many horror stories about them
- We do have members here whose implants got murdered by Qi chargers
- I had plenty of cards murdered by proximity to shitty Qi chargers
I do love the concept thoughā¦
But the only time I actually used one was to intentionally murder my security badge so I could be escorted into the security room at work. (oh, what wonāt I do to prove a point) 
Iāve been unable to kill T5577 chips with any of my Qi chargers but I know that xLEDs are not as rugged.
I wonder if Iām just lucky and bought half decent stuff or if this chip is rugged enough to take the abuse?
Can be both. Can be pairing. Can be current.
I do have a Blackview charger which works with 4.5A current (I miss that phone. 1 weekās worth of charge in under 2 hours)ā¦ And I keep a samsung Qi charger at work. combo both and even DF Classic badges go boom! 
Same trick does not work with an apple Qi charger I testedā¦ but that same charger did accidentally murder a Mifare classic fob (which isnāt even HF) while plugged to the plug that came with it. (Iām still not sure how the heck that happened)
It all depends on a lot of factors aligning. 
PS: not saying Qi chargers will murder an implant.
Just that if they do not follow standards, they may. It would need to be blatantly off from the standards thoughā¦
Yet my experience shows that more often than not Standards within Qi chargers seem more like a mythā¦
[Edit: fixed a product name typoā¦ automode brain] =P
and my personal favorites:
- With devices with a metal casing, it heats up the device like crazy - sometimes to the point of melting plastic.
- Highly inefficient power transfer. The Earthās resources donāt need this.
All that for a little bit of convenience.

Very good points as well!!
Sort ofā¦
I meanā¦ I agree with you there!
I just donāt blame the āwireless chargingā for these issues.
It could be built well and the tech could benefit from a lot of research and fine tunning, but itās a great concept! and one which could go far beyond just a bit of convenience.
Yet, weāre talking about a tech which has existed questionably even before AC delivery/distribution became a thingā¦ and almost nothing has been invested in itās developmentā¦ Worst, most companies just make it into the cheapest gimmick possible all in name of quick cashā¦ 
Thatās the thing: I donāt know that it can. I mean wire power transfer is 99.xx% efficient (depending on the gauge and length of the wire of course). With induction, you can only get close to that with a properly designed transformer with a core. Qi is a poor efficiency air-gapped transformer: itāll always waste power on account of the fact that it needs to be convenient.
With the current state of affairsā¦ I tend to agree with you.
But there are other approaches to wireless than Qi. Not nescessarily fully developed and commercial yetā¦ but could (should) have been better researched.
Yet, my point is a tad bit more Idealisticā¦
Looking into research we have all around it, I feel like itās not so much of a dream to have a city where handheld devices need barely any battery since the city grid would both grant them signal and charge.
The same city grid which would power a network of electric vehicles which would be constantly running also because their displacement would also feed energy back into the grid, etcā¦
This would still have issues with the efficiency and etcā¦ but those would be offset by gains all around it.
The way I see it, AC is like a bitmap image. great for small applications, scales predictablyā¦ but once it goes beyond a certain point itās just too expensive to scale up.
While āwirelessā is a Vector image. Way too expensive for small scale and takes a lot of planning for something bigā¦ but after a certain growth it pays off and scales up naturally.
Hope all my peeps in the southern U.S. stayed safe last night. Weather last night had a death toll of over 100 in some nearby states.

Really heavy rain, but no tornadoes. SW Arkansas. I think the worst of it hit north and east of here. @MegaSTEAM , howād you fare?
Spent about an hour in the storm shelter but no damage near us. Coyotes went nuts when the sirens went off- didnāt know there were so many so close!
If you donāt know Ian Davis, I encourage you to visit his Youtube channel:
To summarize, the man lost 4 fingers and has been hard at work for 2 years devising various mechanical and electromechanical prosthetic devices for himself.
His latest video of him using the latest iteration of his fully mechanical prosthesis is particularly fascinating from the point of view of human augmentation. Take a watch:
Whatās fascinating is his comments at the end of the video where he explains he surprises himself using his hand naturally and without thinking, like he used it before it got injured, and how he finds more and more ways to make the device useful to him in everyday life.
To me, the man is living the magical human augmentation moment we here have all experienced in some way or other (I hope), when the technology blends in so much it becomes part of your life and almost part of you.
One may argue that itās not human augmentation but rehabilitation in his case, because heās going from 90% towards 100% abilities, while we try to go over 100%. But really I reckon itās exactly the same process: I donāt know about you, but I havenāt lost any body part yet I feel I can relate to what heās reporting.
Anyhow, I find it so cool to be able to watch the manās epiphany live on Youtube - almost live!
