Add Wireless Charging to (Almost) Any Smartphone or Tablet

Flagship mobile devices often come with wireless charging capability, but there’s an easy way to add (Qi) wireless charging to almost any smartphone, or possibly tablet, thanks to wireless charging receivers that simply connect to the micro USB port of your mobile device, and can be purchased for as low as $7 on Aliexpress, Ebay, DX.com, etc… I’ve also seen Adafruit made a Qi Wireless Receiver module for Arduino with a 2.54mm pitch connector. They come in various sizes and shapes, but they’re all extra thin (1 mm), with a micro USB connector oriented upwards or downwards depending on your mode, and a thin cable, that allows you to place it inside your phone between the battery and the phone cover as shown in the picture below. It’s not always possible however, as for example the receiver would cover my phone’s rear camera lens, but you could always attach it […]

Samsung Officially Announces Exynos 7 Octa big.LITTLE ARM Cortex A53/A57 Processor

Samsung started to commit code related to Exynos 7 processor to mainline kernel in August, but at the time details were scarce, and many tech websites referred to a Exynos 5433 64-bit processor from Samsung. Exynos 5433 for a Cortex A53/A57 SoC did not make much sense as the company recently announced Exynos 5430 based on Cortex A15 and A7 cores, so finally Exynos 5433 has been renamed to Exynos 7 Octa. Here’s what we know about Exynos 7 Octa from information on Exynos 7 Octa page and an older Anandtech article about Exynos 5433: CPU – 4x Cortex A57 cores @ 1.9 GHz , 4x Cortex A53 cores @ 1.3 GHz GPU – Mali-T760 @ 700 MHz Memory Controller – 2x 32-bit @ 825MHz (13.2GB/s b/w) Display – Up to WQHD (2560 x 1440) / WQXGA (2560 x 1600) resolutions Video – Advanced multimedia format codec (MFC) including support […]
