Samsung S3 finally catches up with the Palm Pre - if modified

Hackthusiast brings plugless juicing to the pottery 'bone


Wireless charging was a key feature of Samsung's flagship Android blower when it was announced, but the replacement back plate it needs isn't on the shelves yet, so one brave soul has hacked a Palm Touchstone charger into the S3 case.

Not that the hack uses the Samsung/Qualcomm-backed "Alliance for Wireless Power" standard, that's not even been published yet, but it does enable a Samsung S3 to be placed on the magnetically aligned Touchstone wireless charger to pick up some power:

The Touchstone was designed for use with the Palm Pre, and hacking it onto a S3 requires dismantling the receiving coil from the back of a 'Pre and jamming it into the S3 case, so not making use of the S3's capabilities beyond the two connectors which stand ready for the official wireless charging kit.

That kit won't use magnets to align the coils, as the standard being pushed by the Alliance for Wireless Power doesn't require devices to be aligned. It also allows devices to be charged from several centimetres away, allowing a new charging paradigm of "power sipping" where the phone picks up energy from the car door, or the office chair, without the user ever proactively "charging" their phone.

When we covered the launch of the 'Alliance we suggested it was just Qualcomm's WiPower standard with broader backing, but that resulted in hurt messages from Samsung saying it had had wireless power for at least five years (in 3D specs as well as elsewhere) and that the new standard would incorporate aspects of WiPower and its proprietary technology.

We asked about Samsung's membership of the rival Wireless Power Consortium, and were told it was "under review", but more than a month later Samsung is still listed as a member of both consortia and the S3 still doesn’t have wireless charging of any kind, other than after being bodged together with the Touchstone as above. ®

  • Robotics and 5G to spur growth of SoC industry – report
    Big OEMs hogging production and COVID causing supply issues

    The system-on-chip (SoC) side of the semiconductor industry is poised for growth between now and 2026, when it's predicted to be worth $6.85 billion, according to an analyst's report. 

    Chances are good that there's an SoC-powered device within arm's reach of you: the tiny integrated circuits contain everything needed for a basic computer, leading to their proliferation in mobile, IoT and smart devices. 

    The report predicting the growth comes from advisory biz Technavio, which looked at a long list of companies in the SoC market. Vendors it analyzed include Apple, Broadcom, Intel, Nvidia, TSMC, Toshiba, and more. The company predicts that much of the growth between now and 2026 will stem primarily from robotics and 5G.

  • Deepfake attacks can easily trick live facial recognition systems online
    Plus: Next PyTorch release will support Apple GPUs so devs can train neural networks on their own laptops

    In brief Miscreants can easily steal someone else's identity by tricking live facial recognition software using deepfakes, according to a new report.

    Sensity AI, a startup focused on tackling identity fraud, carried out a series of pretend attacks. Engineers scanned the image of someone from an ID card, and mapped their likeness onto another person's face. Sensity then tested whether they could breach live facial recognition systems by tricking them into believing the pretend attacker is a real user.

    So-called "liveness tests" try to authenticate identities in real-time, relying on images or video streams from cameras like face recognition used to unlock mobile phones, for example. Nine out of ten vendors failed Sensity's live deepfake attacks.

  • Lonestar plans to put datacenters in the Moon's lava tubes
    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."
