Bookmark Light — Ink which transmits electricity

Bookmark Light — A new bookmark, aptly named, “Bookmark,” from Kyouei Designs has a printed circuit inside along with LEDs that light up when you pinch the bookmark ends together.

Bookmark light
‘Bookmark Light’ is a bookmark which is printed on a special film using the ink which transmits electricity. It can use as a bookmark, also can be used as illumination to use a lithium coin battery. *When use it as illumination, please use only one lithium coin battery (CR2032). *Lithium coin battery (CR2032) is sold separately and not included.
SPECIFICATIONS
year : 2016
material :silver. nanoparticle ink. PET . LED chip .conductive adhesive.
package size : 300mm x150mm

The bookmark is printed on a transparent film using conductive ink that completes a simple circuit when charge is applied to the positive and negative ends. The company recommends using a lithium coin battery to work the bookmark light, but you could likely use whatever battery you had.
If this seems like the perfect gift for your bookworm friend, then you can pick up the ‘bookmark, for about US$16. The tech behind this bookmark is fairly simple, as you can probably tell, but due to the unique design, it is still quite striking. So now, instead of using that torn up slip of paper to mark your pages, use a paper-thin flashlight and never run out of light to read.

DirectX 12 vs DirectX 11

DirectX 12 vs DirectX 11 – How DX12 will transform PC  gaming on Windows 10 DIRECTX 12 VS DIRECTX 11 – WHY DOES IT MATTER? Windows 10  has arrived and, along with integrated Cortana, Xbox One game streaming and a fancy new web browser, one of its key features is DirectX 12, the latest version of the operating system’s gaming API. A software layer that sits between the hardware that powers our computers and the software that runs on them,  DirectX is at the heart of the vast majority of games that run on Windows.  The other major gaming API is OpenGL, which as its name suggests is an open source API. Both offer very similar key functions, but it’s DirectX that tends to be at the heart of most bigger games. Microsoft talks up the amazing new capabilities for every new release of DirectX, but with DirectX 12 it really does have some key new features, at least when it comes to improving performance. It also has some new effects tools and functions for mak...

Android N's "Freeform Windows"

Last week, we wrote about the " freeform window " mode in the Android N Developer Preview. Brief mentions in the developer documents and hints in the code pointed to Android someday displaying apps in resizable floating windows, just like in a desktop OS. Freeform window mode isn't normally accessible in the current dev preview, but shortly after the post, we were contacted by reader  Zhuowei Zhang  with instructions on how to make it work. We'll get to the instructions, but first let's talk about what's actually here. Freeform window mode is just what we imagined. It's a dead ringer for  Remix OS —multiple Android apps floating around inside windows—and it might be the beginnings of a desktop operating system . It works on Android N phones and tablets, and once the mode is enabled, you'll see an extra button on thumbnails in the Recent Apps screen. To the left of the "X" button that pops up after a second or tw...

The Chord Mojo turns good headphones into great ones

The best gadget you never knew you wanted Audio processing isn’t sexy. Better sound doesn’t lend itself to easy marketing through numbers or pretty posters, and so many companies treat it as an afterthought when designing their products. The  blissful ignorance  of "good enough" audio pervades the world of consumer technology, leaving only a niche of audio enthusiasts supporting a few boutique hi-fi manufacturers. Things have been like this for quite some time, but recently a new gadget was introduced that bridges the gap between the many and the few, and its name is the  Chord Mojo . The Mojo is an audio processor and amplifier that’s smaller than a pack of cards yet delivers the awesome performance of much larger rivals. Honestly, I think its size works to its disadvantage because it looks like, and is, a portable unit you can plug into your phone and use off its 10-hour battery. By audiophile standards, it’s almost  too  practical. But ...
