How to attach an ebb to a plastic window with your own hands

Previously, there was already an introductory article about the HS101 oscilloscope, but now it will be supplemented and improved, and the set-top box itself is assembled on a printed circuit board with a connector, and not a surface mount.

In general, it has not changed since that time, the current has slightly corrected.

Printed circuit board

Slightly redesigned to accommodate push-through components.

Was discharged from China, for more details see the article on ordering boards in Chinese offices.

And this is how it should look:

Components

Cool new board. The famous Blue Pill, but now with a USB Type-C connector the way you love it (the MiniF4 STM32F411CE6 was obviously the inspiration).

It costs more, but it's worth it.

The BNC socket (bayonet Neill-Concelman) is the simplest (shitty by the way).

The unit has compact dimensions, which allows it to be easily transported from site to site, easy to operate, efficiently performs its functions and in some situations is simply irreplaceable.

It will be about what a vibratory plate is, what types of plate exist, what it is for, and how to choose an option suitable for specific tasks.

Purpose and principle of operation of the vibrating plate

Vibratory rammer is a vibrating machine designed to compact bulk materials of road bases, as well as soils.

The principle of operation is based on the vibrational vibrational effect of the working body on the upper layer of the material.

Due to a sufficiently large mass paired with vibration, the vibrating plate easily ramps a loose surface.

It happens in the following way: under the influence of vibration, smaller particles, for example, rubble, change their location, as if crumbling down.

The density of the lower layer of the material increases, the largest fractions remain on the surface, the gap between which is filled with small ones.

Under the very weight of the machine, the material is pressed directly.

A striking example of the use of a vibrating plate is the laying of asphalt, when for any reason the operation of full-size construction equipment of road services is impossible or simply impractical.

Construction sites are another place where the machine is used everywhere.

Galileo was the first who thought to use the telescope that already existed by that time for observing celestial bodies. The magnification that his optical device gave was only threefold, but this was enough to trigger rapid technological progress: after six months, the scientist achieved an eightfold increase, and a little later - and 32x.

The main thing to consider when buying: a good telescope is one that is often used. Much depends on the observer himself, and skill, as you know, comes with experience. Before buying, you should decide on the purpose of the device, its design (stationary or portable), the type of mount, and the type of guidance.

How to choose the right telescope

The best all-round telescopes for beginners: budget up to rub

Devices from this category have relatively universal characteristics, which allows them to be used both for observing the planets of the solar system and for studying deep-sky objects. The lens diameter in the telescopes we have selected does not exceed 90 mm, which is why it will not be possible to see objects that are too dim, but there will be fewer flares, which means that you can use the device even within the city. It is also worth noting that beginners are unlikely to want to spend large sums on their first hobbyist device, so we will limit the budget to twenty thousand rubles.

Universal constructs for beginners

Veber / AZ

Our rating opens with a design distinguished by its compactness, excellent light output and reasonable cost. The telescope is great for long outdoor trips, but you can install it at home or in your apartment. The eyepiece is equipped with a Schmidt prism, the picture is straight, not mirrored. The maximum magnification is 160 times - through such a telescope you can see lunar craters with a diameter of about 7-8 km, see the rings of Saturn, the clouds of Jupiter, and so on. The lens here is achromatic, due to which the picture is as clear and sharp as possible across the entire field of view - there are no distortions or coloration around the edges.

Particular attention should be paid to the eyepiece. It is located at an angle of 45 degrees to the axis of the device, and, if necessary, can rotate, fixing in one of eight positions. Thanks to this possibility, observation becomes the most comfortable - you can look at the starry sky both in a standing and sitting position. The picture is straight, not mirrored. The design provides for an azimuth mount, which even a child can handle, there are two micrometric handles that are responsible for aiming, and a viewfinder is also installed. Due to all these elements, the telescope can be accurately brought to the target. A tripod is not included in the kit, it will have to be purchased separately.

How to correctly make the junction of the ebb to a plastic window

It is good if the installation of ebb windows on plastic windows is carried out in accordance with the law. As is often the case in Russia, everyone wants to get money, but only a few want to work it out.

Probably, many people do not understand the very formulation of the question. We already had installers, attached the frame to the opening, and we need to install an ebb. What else is the seam of a plastic window? Why is this? Explaining. According to GOST 30971, which is successfully ignored by most installers due to the fact that Appendix B of the document is recommended, general rules for making joints, seams and joints are described. Here's what it says in brief:

    Assembly seams when installing a plastic window are made with foam. The builders call this blowing. But! The bottom line is that polyurethane foam is terribly afraid of frost. It seems to be a waterproofer, but water is successfully flowing into its cavity, after which the very first frost turns the outer part of the mounting layer into crumb. If steam penetrates from the room along the perimeter of the plastic window, then in severe frost the process will be repeated, but from the inside. This is how, eaten up from both ends by ice, the polyurethane foam crumbles. Then the anchor plates bend, unable to support the weight of the window, and unpleasant consequences ensue.

Seams are protected from moisture penetration from all sides. From the inside and outside, it is, first of all, a vapor barrier membrane that does not allow moisture to penetrate into the seam, but in the opposite direction, steam is dosed through. This is basic information about construction, for more information about the idea of ​​draining sandwiches of building structures, read the sections on frame houses. But the vapor barrier is not the only material. And here's the thing. The membrane must be glued with one end to the profile, the other to the window opening. But! At the place where the window quarter fits, we have no plane, only a gap. It would seem that you can stick a vapor barrier membrane on top, but what about the appearance? And how to fix it? Platbands and slopes? Too difficult, so many standards recommend the use of PSUL (pre-compressed sealing tape). It is glued to the frame itself or a quarter on three sides of the perimeter (excluding part of the low tide). Expanding over time, the tape completely clogs the access for water to the inside of the seam. Finally, on the side of the wall, the waterproofing is ensured by treatment with a special primer. This soil should not allow water to pass through.

  • According to GOST 30971, window sills and ebb tides can also be planted on foam. As well as the slopes. At the same time, other types of finishes using insulation are allowed. Let's see how the ebb is usually mounted by many seemingly experienced craftsmen. To do this, a piece of the profile (usually steel) is cut off in place, bent at the edges, holes are drilled on the setting tooth for attachment to the frame. Then the seam of adherence to the frame is blown out, the foam is applied with a snake along the bottom of the opening, some still make the finish line along the street edge. And that's it! The ebb is put in place, pressed by hands, screwed on. What don't we like here?
  • Window tides

    If you have successfully selected and installed newfangled plastic windows for the finished architecture of the building, slopes, canopies and ebb tides, such work can be considered unfinished.

    Firstly, if you do not know what an ebb and flow at a window is, for what purpose they are installed, you need to apply for the information offered on our website. In everyday life, ordinary citizens call ebb tides window sills. But if you look at it from a logical point of view, the ebb is necessary to drain water from the outside of the window. That is, the water will not stagnate in the gaps of the window opening and the operation of the frame will last for a longer period. If the window is plastic, you should install a plastic sill. This technique will give the window a finished look and fit into the architectural appearance of the building.

    In order for your window to be fully protected from atmospheric precipitation, it is not enough to be limited to one low tide. Care must be taken to install the visor at the top of the window. At the present time, there is a wide variety of materials for the manufacture of visors and ebbs - this is PVC, galvanized sheet with a plastisol or polyester coating

    To determine which auxiliary elements are better for installing on a plastic window, they need to be matched with the color and material of manufacture of the window itself, as well as pay attention to the window ensemble to harmoniously fit into the architectural appearance of the building

    Installing window tides

    Slopes are an equally important part of the processing of the area around the perimeter of the window opening. Due to the fact that the thickness of a wooden window is much thicker than a PVC window, when replacing an old window with a new one, a forced problem appears - this is the finishing of the slopes
