Fir-tree burn! We take the smartphone, the mobile Internet and … we include "fir-tree" at the dacha

2 years, 12 months ago

It will be a question of how to manage electric devices via the Internet. The task is rather simple if there are a good, wire Internet and, especially, static IP address. But when an Internet access is possible only via the GSM modem, for example, at the dacha, the choice of solutions is not so big … but is! Now to worldwide network it is connected users more, than inhabitants of Earth. Full Internet users are different devices for a long time and many of them communicate among themselves, using the popular MQTT protocol, more than once here described. At the Master Keith there are several devices which also use the MQTT protocol and a free cloud server of iot.eclipse.org. It will be a question of their setup and application.

DIY powder for the dishwasher: we sort industrial means and we improve the recipe

2 years, 12 months ago


Attention! In the recipe with bleach danger of corrosion of metal was found! It is not recommended in standard application!

In the last publication we created cheap powder for the dishwasher from acorns and matches of the calcinated soda and laundry detergent. In this I will tell about how it is possible to improve it by means of oxygen bleach and where it is possible to purchase components for more advanced version. Let's place emphasis on efficiency of washing, but even at the same time the price will not go beyond 100 rubles/kilogram. And still there will be a recipe of a conditioner with cost value around 1 ruble for liter. As fairly noticed amarao, occupation not for all and it is simpler to much to use ready tablets. But in similar experiments with household chemicals there is something from the childhood, the first experiments on mixing of soda with vinegar and aerated water with mint candies. So the notable economy here after all is secondary. Let's have a good time) If laziness to read someone all text — at the end of a post there will be detailed recipes with recommendations.

New year in Sisadminye or As most to collect the geek indicator of a holiday

2 years, 12 months ago


Stanislav Mushinsky, technical support specialist of Mail.Ru Group

Hi everyone! Today I will tell how from improvised materials to collect what it is possible to call the indicator of New Year's mood.

This idea at me appeared after the friend showed the Russia map found in the Internet created from motherboards. Big cities on it were highlighted by diodes, and the monitor in the middle was located. As far as I remember, the card played a role of an advertizing logo. Having admired implementation, I for fun told that it is possible to create something similar with little effort and from make-shifts. And then the joke became reality.

Ну, а сейчас есть и еще одно аппаратное расширение — это WiFi модуль. Да-да, теперь Commodore можно подключить к Сети.

As I on A20 Debian put

2 years, 12 months ago
I to myself here purchased such payment. A20, gigabyte of a RAM, 4 GB of nand, and heap of the periphery. The same kubibord, but with Russian razraby it is also not necessary to wait for month with Ali.
Personally for me pluses of this borda was:
  • On a reverse side there is a sata-plug — it is possible to fasten hdd without lots of wires. It is very important because a little bit a prefektsionist and I do not love when wires occupy volume bigger, than a payment.
  • On a payment two lvds are divorced even. That is we take any matrix from a laptop, we cut off the small connector, we put on its place BLD2x15 and all. If there not a wire, but a loop, then on Ali it is possible to purchase a ready wire for couple of dollars. The Chinese noutbuchny matrixes cost a spear in comparison with ready screens of the same permissions and sizes.
  • Almost all connectors go on one edge of a payment. Here never understood that moves the developer of a payment while he puts plugs on all four parties? First raspberry bright to that example. What for? the Body normal you will not make, on a table takes places of time in 6-9 more, than itself the size if where to insert — it is necessary to unsolder all these connectors...

But the payment has also small minus. Plath new and razrab was made under it only by buildroot with QT. And some have not enough of it … I wanted full-fledged system, as on a desktop. What for? About it and article.

"Why to pay more?" or layfkhak on creation of a hemisphere for GoPro

3 years ago
All hi. Today in a heading "kolkhozy" we learn houses how to take such wonderful picture by means of Gopro. I think for the first time when each of us saw such photos on the Internet, at once wanted to themselves GoPro!

However we collected money, purchased the camera, went to bathe, but did not achieve such photos. "Again the marketing mix probably, and in general is not GoPro" — we thought. However if to understand in this case, then everything is quite simple.
