iPhone 4S Wireless Charging Mod Goes Well With Wireless Syncing

Even though I’m not a fan of current wireless charging technology, I’m still impressed by YouTuber tanv28, who modified his iPhone 4S to support wireless charging. Pair this with the wireless syncing feature in iOS 5 and you can ditch your charge and sync cables. If you can pull off the mod, that is.

As tanv28 warns in the video, this is not an easy project and it will void your warranty. Such is the price of convenience. You’ll need soldering tools, a thin gauge wire, a spare charger port assembly, a spare iPhone 4S back cover and the wireless charging receiver and circuitry from Powermat. You can skip to about 1:00 in the video for the steps:

Proof that Apple runs in his blood, tanv28 even made a commercial for his customized iPhone:

Tanv28 didn’t mention if his iPhone can’t be charged via a cable anymore, but judging from his thorough guide I’m betting that it the dock connector still works, otherwise he would’ve mentioned it. Now all he needs to do is make his iPhone float.

How Many Engineering Students Does It Take To Create a Levitating Glowing Light Bulb? [Video]

Just one, as Chris Reigler, an electrical engineering student from the University of Queensland in Australia, discovered. His floating LevLight project could one day revolutionize the way we change burnt out light bulbs, and make thousands of “how many X does it take to change a light bulb?” jokes completely moot.

iPad power costs $1.36 a year

For a device that’s so extremely popular that the rest of the tablet market is inevitably compared to it first and foremost, it seems that the iPad is undeniably inexpensive when it comes to cash needed to charge it up. The iPad has an internal battery – a rather large one, at that – and according to Electric Power Research Institute, it’s only costing you an average of $1.36 USD a year to keep the device on. This study also included several other devices and electronic items you’ve got around the house as well, with the most expensive item being a refrigerator at $65.72 per year.

This study showed a desktop PC to be costing you $28.21 USD a year on average to keep powered up, while a 60-watt compact fluorescent lightbulb costs users $1.61 a year (surely not constantly running that whole time, of course.) The EPRI focused on the iPad in this study since it is without a doubt the most talked-about device on their list, and they’ve come up with a few other interesting points as well.

An average desktop computer uses 20 times more power than an iPad, said the study, and if the number of iPads tripled instantly to 67 million, we’d only need one small power plant operating at full strength to provide enough power for them each to be charged up whenever necessary.

These iPad tests were done by EPRI researcher Baskar Vairmohan, who studied the effects of a possible switch from the current notebook and gaming console culture of many to a one-tablet household (one tablet per person, that is.) What he’s found is that with the trend of tablets replacing notebooks and desktops at a rather large rate, we could be looking at a big decrease in power consumption in the near future.

Of course there’s also the iPhone, which Vairmohan calculated to cost just 38 cents per year to keep charged up. Imagine if the only device anyone had was that – cash in!

New fuel cell keeps on going even once the fuel’s dried up

New fuel cell keeps on going even once the fuel''s dried up

Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell — developed at Harvard’s School of Engineering and Applied Sciences — that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can’t store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you’re always running out of sugar.
