Progress in the development of photography in recent years has made it accessible for everyone. Simple photography getting without the hassle is quite cheap, but colorful and high-quality images on materials of different companies in specific locations have forgotten a very interesting area of photography, used the once popular. We are talking about the photo, or volume. This was produced and a special stereophotography with two lenses, and viewers to view the resulting images.
MY HOME IS MY CASTLE
Regular subscribers know that the individual building our edition pays a lot of attention. Regularly posting a variety of projects of houses and thereby communicating with readers-developers, we have seen that many novice builders-gardeners have little idea about the process of building a house. On the initial stage of construction of the home says a Finnish Builder and teacher, Ranti Hurmalainen.
ARSENAL HOME WORKER
Today’s “unobtrusive service”, which have to apply for the small problems of household systems, effectively “bite”. Even the call an electrician, technician or plumber to diagnose, not to mention the simple elimination of minor faults, is quite expensive.
Therefore, minor damage or imperfections is much better to perform on their own. But to do this at home worker should be at least the most basic set of working tools. But if the head of the family or children, there is also passion, desire something to make with your own hands, you will need an Arsenal of tools.
HANGER FOR KEYS…
If a little old picture in a frame under glass has not found a place in the room and turned on the mezzanine – take it out and after blowing the dust, breathe new life into it: make of her housekeeper – a kind of hanger for keys. Under the picture will only need to fabricate (or find a suitable size) a simple box. On the side wall of the box to fasten the loops (or cut piano hinge): hung on the frame pattern forms a door of the housekeeper.
INSTEAD OF A COAT HANGER
And in the wardrobe in the book (Yes, probably, and in the kitchen), there are always small things that almost prevented the placement of the primary storage. And here come to the aid of ordinary clothespins. Attach them on the inside of the doors – get convenient clips for hanging sheets or flat objects, as Read more…
THE MACHINES
What does it mean to have a part in? You need to perform sequentially a series of manufacturing operations, and as a result, the workpiece turn into the finished product. For example, it is necessary to manufacture the bolt. Hex metal rod the thickness of a future head of the bolt is fixed in the spindle of a lathe, turned to the body diameter of the bolt, then cut the threads, measure out the desired length of the bolt and head and cut off from the web. In the manufacture of the bolt, as in any other production process, it is possible to allocate operating procedures (for example, the groove of the rod, threading) and auxiliary operations, or actions (consolidation of harvesting and removal from the machine the finished product).
THE SOUND WILL BE LOUDER
In order to obtain a sound signal of high power (10 – 20W) from the simple Assembly of a sound generator, does not require complex amplifiers WOOFER.
The generator on the popular chip KP1006BU1 (DA1) is enabled by almost classical scheme and in the description is not needed. The output frequency is approximately 1000 Hz. It can be considerably corrected by changing the values of the elements C2 and R2. The output frequency in this circuit is calculated by the formula:
F(kHz) = 1,44/(R1 +2xR2)xC2, where the resistance of the resistors R1, R2 in ohms, and the capacitance of the capacitor C1 is in microfarads.
SAND FLEA – JUMPING ROBOT
Someday there will come a great time and robots of the future will clean our planet from Homo Sapiens.
The American company Boston Dynamics makes this the perfect time has come as soon as possible.
For fighting in an urban environment these guys come in handy a light scout that can jump into the window of the house and quickly provide targeting heavier brothers.
ROCKET HAWK
Models of this type have many times built by the guys from the mug space modeling of station of young technicians of the city of Elektrostal. They especially appreciate its “Hawk” because it is made from material in the public domain (Linden, pine, paper), and thus has good performance as in the active phase (engine running), and in gliding flight. Such “hawks” the club has participated in local and regional competitions.BENCH-CHANGELING
Compared to a simple bench garden bench with back much easier, and looks nice. However, recent years in urban parks and gardens, and in suburban areas are often on the bench cannot sit down because the seat is stained with traces of dirty shoes. This is a consequence of maloestetichny behavior of youth – fashion to sit in the seat and put his feet on the seat. The administration is trying to deal with this all sorts of homegrown ways, until the spreading of the upper edge of the backrest of fuel oil or even eliminating backless benches.
