Pi Charger Uses Qi Standard to Extend Wireless Charging Reach Beyond Current Mats

[melendezest]

Oh please. Nobody has "disdain" for traditional families. Save your inflammatory rhetoric for your own social media echo chamber.

I was being somewhat facetious (in reference to the "sperm-count" allusion) but the first two items I mention are examples of such "disdain". The "traditional family" in question refers to the child-rearing type, which both examples I mention make moot, as well as a "low sperm count".

I do concede it was inflammatory and perhaps better reserved for the PRSI forum, and leave it at that.

Not as much as I do.



Yes



No


Meanwhile all the crap you breathe in from diesel and petrol cars outside IS taking minutes off your life every time you have a walk, it has been verified and it is fact - but no one seems as bothered about that cos "RF signals maaan"

Oh I hate the latter too. I wish every ICE vehicle on the planet were electric. Big advocate of electric vehicles.

Thank you for informing me on electricity through the air. I kinda knew there was no issue here but I thought I’d find out before claiming anything

 

[LarrySmith]

Hahahaha they might make it an open standard...

314? Why so exact?

Pi Chargers... even if it is pronounced differently... just going with the spelling.

Did anyone notice how its also warming her coffee, that beverage heating feature alone makes it better than the competition.

 

[ackmondual]

One wonders if this will effect sperm count.

Are there any studies on this BruckU?

Not a single mention of health risks... that's reassuring.

One would think being around wifi and radio signals from cell phones would've triggered concerns long ago, but yeah, I'll acknowledge that we've had time to address THOSE issues, so I digress.

 

[rafark]

I love it so much. It'd be perfect to have it next to my bed charging the phone while I use it.

HOW-EVER, I'm deeply concerned about health risks, there's no way that thing radiating energy and god knows what else won't harm you.

 

[Phonephreak]

This is great news. Just having a couple feet of charging zone makes a huge difference. I will absolutely buy this when available.

That must be one healthy coffee...

couple of feet? its max range is 12 inches, with the charging speed slowing as you get further from the device.

I understand this. But as they improve the tech 2’ would be a great. Large enough to charge when in a general location.

 

[RiddlaBronc]

I bet samsung is already on it. They will be the first to introduce truly wireless charing. Hopefully by iphone XX we will get it.

 

[kdarling]

Not unless you sit on top of the device on the table. Otherwise you're pretty far away.

Look, the reason why sperm count decreases with cell phones in your pocket is because of induced heating. It's the same reason couples trying to get pregnant avoid a hot bath for the husband before having sex.

Hopefully the partnership with Energous will yield something even more impressive, and not too far in the future..

That'll happen about the time that the universe reboots under a different god who has different physical rules in mind.

I.e. no more pesky inverse-square law to rapidly diminish the power over distance.

Alternatively, could happen in this universe if the FCC allows kilowatt transmitters in every room of your house.

Who cares who figures this out. True wireless would be cool

 

[Jamie0003]

I like the idea of this, but the range is still way too short. I don’t see what this improves over Apple’s version with the AirPower, as the range is only a foot. That’s barely long enough to use your phone in bed.

Plus, it’s massive, who would want that taking up your entire nightstand? A charging pad with support for multiple devices makes more sense. I can only really see this being useful in a coffee shop.

Don't you know anything about math? It's pronounced "Pie".

Also, has nobody here heard of the Raspberry Pi?

 

[dannys1]

Do a search on Amazon for "DIY Qi wireless charger."

Here's an example of one guy modifying his Tesla with a Qi induction coil:

Nice one dude - I actually watched a similar Tesla video (and i'm about to get a Model S actually) so the first place I was going to put one was in a tray - I just wondered if I could modify the coil size to make it a bit bigger or fit areas other than a little circle.

 

[dilbert99]

Now that is very nice!

I really wish you could buy the raw induction coils with a USB connector so you could make your own in furniture stuff a bit better.

I'm not interested in the charging mat thing at all - but if I can hide induction charges in multiple furniture places and in places in the car, that makes it much more useful.

I don't want to have to buy 5 pad charges to take it apart to cover the entire arm of my sofa though!

Might be cheaper/easier for most people to buy a mat and take it to pieces and install that in furniture you make. (in the absence of kits being available)

I think the number of coils needs to be within a given range since the charger is behaving as a transformer, the number of coils in the primary (mat) and secondary (phone) need to be related such that the phone gets the correct induced voltage.
The phone will have a voltage regulator that allows it to accept a range of voltages, but you need to be in the correct ballpark with the induced voltage.

I guess you could add multiple coils like in the images that other person posted.

This is the sort of thing I was expecting Apple to be releasing at some point...

Hopefully the partnership with Energous will yield something even more impressive, and not too far in the future..

I'd take that one as snake oil for the time being...
They show in their demos charging multiple devices at once but haven't actually achieved it yet. (As of sometime in their 2016 filings so that could be out of date)

"
We may not be able to achieve all the features we seek to include in our technology.


We have developed a prototype of our product concept that displays limited functionality in a laboratory setting. There are a variety of features we seek to include in our technology that we have not yet achieved. For example, while we believe recharging multiple devices on one transmitter at a commercially acceptable level may be possible theoretically, we have not yet achieved these results, even in the laboratory. We believe our research and development efforts will yield additional functionality over time. However, there can be no assurance that we will be successful in achieving all the features we are targeting and our inability to do so may limit the appeal of our technology to consumers."

I am still concerned with these magnetic fields adversely affecting all the magnetic strips that live in my wallet. I also want to know if these fields will kill NFC containing door entry cards. I have one for door entry in my phone case, and another (different door) in my wallet.

I am assuming that a non-ferrous phone case won't impair the wireless charging function.

I have been hoping for wireless charging since the early versions came out. My iPhone6 lightning port might last long enough for me to obtain the iPhone X.

Not sure about the magnetic strips, most things are moving to chip and pin, the magnetic strip might eventually be taken away.
I can't see it affecting nfc.
Probably any metal case would affect wireless charging. Or at the very least, iron, copper and aluminium (but I am no expert...)

 

[Analog Kid]

This seems both useful and plausible. I have to wonder though: if Qi is pronounced "chee", how is Pi pronounced?

One nit regarding the Pi description:

The closer the device to the Pi, the faster it charges, with a gradual drop-off in charging speed the further away the phone is.

If it's inductive, and Qi is inductive, then it's not a gradual drop off, it's precipitous. The magnetic near field decays with r^4.


I really wish MR would give up on the Energous idea...

The Pi might not reach the distances claimed by Energous' WattUp technology, which uses radio frequencies to charge devices from up to 15 feet away, but it does offer more flexibility than existing pads that devices must be directly placed upon.

Energous doesn't reach the distances claimed by Energous. Milliwatts at 15 feet don't justify the installation of an antenna that's also dimensioned in feet.

As for Apple, there is plenty of anecdotal evidence to suggest it has partnered with Energous to work on bringing a truly wire-free, over-the-air charging technology to its consumer devices, but we'll likely have to wait for at least another year to see the possible fruits of those labors.

Please stop pushing this nonsense. Even Disruptive Tech Research appears to have pulled the article you're referring to. This is the evidence you attribute to Louis Basenese Baseless:

"Apple is working with a partner rather than developing an in-house solution due to the small number of patents the company has filed surrounding wireless charging"-- note that Qi also allows Apple to deploy a solution without their own patents.

"he points towards their common manufacturing partners (TSMC and Foxconn)"-- most of the world uses TSMC and Foxconn, that's like saying their working together because both companies are based in California.

"he points towards ... their membership in ANSI working towards standards for wireless power transfer compliance testing"-- which ANSI group is this? I can't find reference to it anywhere including on the referenced site. Publicly being members of a standards committee does not mean you have a private business agreement.

"he points towards ... the fact that Energous's RF-based wireless charging system is the only long-distance solution nearly ready to launch." -- isn't this kind of circular? Energous is about to launch through Apple because they're about to launch?

And the claim that Energous signed a deal with a top five consumer electronics company? "Of course, the identity will remain a mystery, as AAPL's notorious about insisting on secrecy with partners and employees."-- it must be Apple because they won't give a name and we all know Apple keeps secrets?


May as well say the companies are linked because Apple ends with an 'e' and Energous starts with an 'e'...

If you want maximum coverage you want to get one with 2 or 3 coils.

I'll be looking to do this when I get my Model 3

 

[jaack]

So according to their website "it follows existing FCC safety guidelines" and uses weak magnetic fields: https://www.picharging.com/technology/

Excited to pick one up once they launch!
