MP8036multi: example of work as the thermostat

1 year, 9 months ago
In the last publication we gave an example of work of BM8036multi in the timer mode. In this part we will consider operation of the module in the thermostat mode.



In many country houses the gas boiler providing heating of the house and supply of hot water is set. Often these boilers – an old sample or very budget, not having the sufficient level of automation. There is a natural desire to finish these boilers and to increase comfort and safety at their use.

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

1 year, 10 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.

MP8036multi: example of work as the timer

1 year, 10 months ago
Recently at the Master Keith innovation appeared: the MP8036multi module which represents the multifunction configured controller with simple and clear commands.



Uniqueness of the MP8036multi module consists in flexibility of its configuration: the status of outputs of the controller can depend on different combinations of statuses of inputs. At the same time programming of this module for any specific objective should not cause any difficulties. Based on MP8036multi it is possible to automate a lighting system, management of heating, emergency supply of the house or giving, to automate watering and ventilation of the greenhouse, and also to implement many other solutions.

As the first simple example we will tell how to construct management system a diorama.

3D milling cutter? There is no 3D printer. Epilog

1 year, 10 months ago
In the previous article I described option of production of the body for electronics installed on the 3D milling machine with ChPU by a milling method. The body was cut from the two-layer ABS plastic intended for a mechanical engraving.

Now we will make one more body of the same STL files, but on the 3D printer. On video I printed parts on the 3D MC3 printer – stealth.

As I finished the 3D MC2 printer from the Master Keith

1 year, 10 months ago
I am at heart a person fond. And first of all any electronic and iron features. I mean any useful devices working under control of electronics by this term – home automatic equipment, lighting, ventilation, remote control by this economy. It is clear, that against the accruing craze 3D printing I could not pass by.

Why to me 3D printer?. Vague thoughts wandered in the head: I will print some body, a podstavochka, a ruchechka … Solved so – I will catch this thingummy, and there it will be visible!

The choice after short searches stopped on the most available option (what could find), but that if something happens would be where for the help to be stuck, that is local Moscow. My choice on the designer of MC2 of production Master Keith fell.

Switching of the external power amplifier by means of the MP2898BT mediaplayer

1 year, 10 months ago
The MP2898BT multimedia player is very convenient as actually a player and as base for creation of wireless speakers, audio systems, etc. As a rule, together with MP2898BT the power amplifier who it would also be desirable to include or switch off together with a player works at home. It is possible to implement this task by means of BM146 switching unit, however there are some subtleties of connection which we will in detail consider. + bonus: video of use of the mediaplayer with the regular radio tape recorder in the car.

Three five for the electronics engineer

1 year, 10 months ago
The Master company the Whale which is letting out a series of the training sets for beginners under the general name "Alphabet of the Electronics Engineer", of course, could not ignore such known component as the "legendary" integral timer NE555. And, if in the first set "Fundamentals of Circuit Engineering", 15 elementary schemes using the principal electronic components (resistors, condensers, transistors, diodes) are considered, then in a set which we called "The classic of circuit engineering", 20 schemes using the timer NE555 are provided.

Saundbar from old computer columns

1 year, 10 months ago
Long these columns lay at me, all the hand was not raised to throw out them. Waited and hoped that I will be able to give them the second life. Columns were purchased 20 years ago, and still I did not meet even relatives on quality in such body. Unfortunately, the columns noname have also no number on the body, is only proud the logo of IBM flaunts.



Perhaps, someone will remember these babies, and at someone they serve, to this day, as at me. And bluetooth the MP3862BT module from the Master Keith allowed to give the second life to columns.

Remote control of oar gate

1 year, 11 months ago
There is a large number of commercial products, for remote control of sliding or oar gate. But what to do if there is a mechanism, but there is no electronics or it failed?



We offer for a solution of a problem of remote control to use the MP325M module. The module contains two 10A power relay on operating voltage in the structure 250B with normally opened and normally closed contacts that it is quite enough for management of any sort of motors also two inputs for connection of ends of restriction of opening/closing.

3D-printer? No, 3D - a milling cutter

1 year, 11 months ago
Around a 3D Masterkit thanks to our MC2 and MC5 printers quite big community of fans of 3D printing already gathered.

For them 3D-printers gradually became a normal and necessary thing in house workshops. And so! The community demands development of house modeling and long ago look towards milling machines, dreaming of such inexpensive, easy-to-work home milling machines.
Time dream — it is necessary to do. Time should be done – made!
The milling cutter, and a 3D milling cutter turned out not just. It is possible to look at appearance of a milling cutter on our website.

Below on a photo all parts of the designer – structure, kinematics and electronics are shown.
