Tried it: A4Tech holeless - No holes under the sun

If you already have a hole, I remembered one of my favorite music to listen to, if for no other reason, because they sing about a black hole in it, and this is almost on the new mice, plus further enhancing parallelism, the mouse also emits invisible light . Holeless, from now on it will be the name of the technology.

We relaxed, hummed, now let's deal with the mouse!

I don’t know who is with him, but I love my blue laser mouse. It's a good little mouse, but sometimes it'll be a bit full of…, to put it mildly, so my putton. There is a small opening at the bottom, really not big, but just enough to sit in a little dust and lint. I don’t even know how it can be, but it’s as if it attracts dirt that interferes with its operation. At such times, of course, always at the worst moment, say during image retouching, you start to jerk and get there the exact operation. You may come blowing into the hole to please already properly squirm the mouse pointer.

Okay, who says we need to clean the apartment and there will be no problem, that’s right, but unfortunately the dust situation is a bit catastrophic for us, especially in summer, plus a dog, four at a time, so the incidence of lint increases.

I don’t think anyone is surprised after this that I studied with interest the chassis of the new mice in the Kelly-Tech showroom, looking for where the laser is coming out, since there is no hole in it. As it turned out, my tip came in, but the fact is that the designer is trying to convince us that there is no laser here, though there is.

Here we can also turn back to a section of the introduction, which was about making smart things from two forints. Well, this is not an exaggeration in this case either, as the cost of materials may reach two forints, but the benefits gained are worth much more.

All that matters is that the A4Tech has paired the laser, which is incident 90 degrees, with a plastic prism that directs the light behind the mouse's belly to the outside through a lens, and then the reflected light arrives here, which is then processed by a sensor. . The tricky engineers decided to make the lens look black from the belly of the mouse, making it essentially completely invisible.

Of course, this solution also has a much more useful feature than aesthetic considerations, even that the belly of the mouse is completely closed. There is no dust, no lint, no water, nothing that could disrupt the operation. And all this is due to a bit of thinking and a two-forint part.
