Following the requirements of engineering designers more and more to “humanize” modern technology. In particular, be equipped with machine devices to provide voice prompt about the action in a particular situation.
It happens that the boom lifting mechanism is not enough, and the load required to lower only slightly.
Cut or broke off and remained in the hole pin or a tap when cutting threads in cast iron or aluminum parts — it is unpleasant, but not hopeless. Rescue proven the following simple technology: the hole reams a larger diameter, allowing not only to remove the chip, but to cut a thread and screw stem nut on new stud or bolt.
For model railroad two rail strips are made from sheet aluminum. They need to be screwed to a wooden block. They mounted on the side bars of wood that make up the profile of the mound. In the corners between the rails and the wooden blocks glued slats that allow you to save the profile rail. On top of the mound, stick the strap-sleepers. After assembling the pieces of wood with glue BF, sprinkle with a mixture of river fishing line and crushed slag. A thin layer of this mixture clinging to the tree, creates the semblance of a mound. The sizes are selected depending on the scale of the models.
I suggest a small revision plectropterinae unit G-602, which are widespread to the store “VEGA-109 stereo” and some others.
The frame is made of planks 10 mm thick, glued with joiner’s glue. The lazy side walls are inserted two ordinary glass and are secured with strips of sheet metal. A stand for the bulb to make aluminum wire Ø 5 mm. Cord with plug is output through the opening in the side wall of the frame.
You can buy a kitchen inexpensively at the store or make an individual order on a modular design. You can buy a kitchen inexpensively at the store or make an individual order on a modular design.
Information stored in the computer, it is sometimes necessary to put on paper. The result typically looks like a stack of A4 sheets, stapled one side with a stapler. But easier would be to have a printout in the form of smaller format books, a small notebook of nested into each other bent sheets, or (if the pages of many) of several such notebooks, stitched together. How can that be?
Even in the recent past 10АС9 sound system, each sound column which contains two versatile dynamic loudspeaker (one for low and medium frequencies and the other, with a diffuser of smaller diameter for higher), it was considered perfectly acceptable for a home stereo. And electrical parameters it was on a high level: power 10 W, impedance DC current 4 ohms, audio frequency response 40 to 18,000 Hz. With the advent of so-called Hi-Fi equipment these speakers have become increasingly depart among the almost Museum pieces.
I offer a homemade device allows you to control voltage vehicle electrical system. In particular, that’s all right — the battery is charged and generates the required 12-14,8 V, the signal indicator is green light. At lower voltages the light turns yellow, and when elevated — red led.
