We programmed under Pebble. Lesson of second: A stone g answers, dice and sex cubes

4 years, 9 months ago
Clocks — it are finite well, but they hammering all site. It are necessary to make something more interesting.

Remembered a ball from «a route 60»? Let's make it analog — the application answer on a question.

We done the detector of driving, or OpenCV — it are simple

4 years, 10 months ago
It are necessary to justify a title of the company — to be engaged though something that are connect with video. On the previous topic it are possible to understand that we not only done a teapot, but also we sawn «clever lighting» for the clever house. For this weeks I were occup with that OpenCV picking — it are a dial-up of algorithms and libraries for operation with computer sight. Searching of objects on images, recognition of characters and so on.

Actually something in it to make — not such challenging task, even for not - the programmer. Here I also will tell, how.

LeapMotion. What inside?

4 years, 10 months ago
While operation with a teapot are restrict to compilation of the documentation (that, are undoubtedly enough boring for habr — I judges on the previous topic) I will write about the abstract — about an interior zhelezyak. For the following project (control of lighting) it were required to us to light up a subject of OpenCV and cameras suitable to this business.
At the same time it would be desirable to receive also a card of depths with video — for change of luminance depending on distance to the person.

Ha learn about that in the LeapMotion controler two cameras was us, we there and then order it «on potykat».

About competitors to our WiFi-teapot. iKettle

4 years, 11 months ago
Some days ago there were a news that we could not claim for a rank «the first teapot with WiFi» any more.

British (as far as I understanding) the company letting out a teapot who are able to turn on on WiFi c the help of application for iOS and Andoid.
More low some photos, video and my speculations about, why it not absolutely that we done.

About protocols say a word … Or let's develop a teapot together!

4 years, 11 months ago
Actually not only about protocols, and are faster about logic of interaction of difficult systems. It not BigData, of course, but all the same are over what to break a head and spears.



Still at the very beginning of development, I threatening that I will tell about it on the air that any reader c participate in this entertaining process. And here, time coming. The prototype at us are almost ready, and we now engaged in the documentation for manufacture and for development of the server and mobile application. Also underst that a prototype — this most simple, and all those tasks that we solv in it — it so, a kindergarten, trousers on straps.
Here you reflect sometime, how much difficult logic worked, when you sent tvit or postite a photo? It it are not visible, in 99.9 % it are latent from the user, and are more its absolutely imperceptibly. I too doing not note it, until, when I had to project it most.

We looked at the world eyes of a cancer-bogomola: short-range infrared range

4 years, 11 months ago
And you th, we only was able to do teapots? Not - and.

All of us g used to that flowers red, black surfaces done not reflect light, Coca-Cola opaque, a hot soldering iron it are impossible to illuminate anything as a bulb, and fruit can be distinguish easily on them to color. But let's present for a minute that we could see not only a visible range (chi chi), but also short-range infrared. Passing infrared light — it at all that it are possible to see in a thermal imager. It are faster more close in visible light, than to thermal radiation. But it had a row of interesting singularities — often absolutely opaque subjects in a visible range was perfectly appear through in infrared light — an example in the first photo.
The black surface of a tile are transparent for an IR, and by means of the camera at whom the filter are remov with a matrix it are possible to consider a part of a board and a heating element.

WiFi Kettle or as the idea turned to the serial device

4 years, 11 months ago
I thinks, to be represent sense had no, as here many known me, and asauthorthe differentarticles , and as creator of Box Overview. I long doing not write, because were occup by the one interesting project.



Yes, that article (A clever teapot for the clever house) — it about us. I doing not plan that about our project will write so quickly, but becoming clearly that interest to it are, and it are necessary to write already about it more in detail.

All beginning here with this my article wr literally for a pair of clocks in which I showing how by means of a board on MSP430 and the Chinese box with android can be switch on and off far off through the browser loading. Still assuming that so it are possible to include a teapot when laziness for it to go to other room.
