REED SECURITY — SIMPLY AND EFFICIENTLY
Security systems are a rapidly developing area of modern electronics. Published a huge number of various schemes and designs that can make anyone a couple of times was holding the soldering iron. For example, “electronic security guards” can warn of an intruder enters the premises or to signal the presence of the recorder for unauthorized sound recordings.
RECUMBENT IN BOX
Once the attention of mushroom pickers has attracted tourist from approaching trains in bright veloform, helmet with “cello” in the case behind. Removing the box and opening his zipper, took out of it… brilliant frame with wheels. A few motions – and before the astonished mushroom was already a three-wheeled velomobile. The box on the trunk itself – in the saddle, and in a minute a tourist in a strange car disappeared around the bend suburban road…
STIRLING ENGINE
The Stirling engine is a heat engine invented by Robert Stirling in 1816. It differs from the internal combustion engine because the fuel burns outside the engine, making it much easier to manufacture. There are Stirling engines that run from the heat of your hands, although they are a little harder to build. The Stirling engine would be a good addition to any collection of those who like to make things with their hands.
GARAGE-TYPE “SHELL”
The garage-type “shell” have already become usual for our urban yards. However, in many cases — for example, in the country — you can install a simplified shelter, make on to the motorist.
BODIES
The organ is a very old key wind musical instrument, the largest and most complex of the available tools. Its distant predecessors were, apparently, bagpipe and pan flute (set of reed pipes of various sizes). The very name “organ” comes from the Latin word organum, in ancient times was called musical instruments at all. It comes from the Greek organon – an instrument, a tool.
TO FIX WITHOUT MOUNTING
So will be able to do if you need to glue some detail to a vertical surface. There is a simple way really allows you to do in this case bezdolnogo temporary fasteners will be replaced by pressure: the load suspended as shown in the figure.
FIGHTER I-5
FIGHTER I-5. Scale model 1:33.
The history of this car, dubbed the I-5, began in the summer of 1927, when Polikarpov developed a preliminary draft of the fighter under the British motor Bristol “Jupiter” is one of the best in those years of power density. This gave the opportunity to provide good maneuverability and rate of climb. Technical Council Aviatrust Polikarpov suggested to consider the inclusion of a new fighter in the prototype development plan and approached the BBC with a request to present to him their tactical and technical requirements. Design And-5 plan had to be completed in November 1929: in October of next year, it was required to produce to the test.
THE POOL OF TIRES
In the place where I decided to build a pool near the farmhouse, was an old pond that once served as a fire pond, and dog walking for Pets geese and ducks. But as time passed: for fire protection purposes now have running water, and the house became a cottage and birds do not hold here. Yes, and the pond gradually silted up and overgrown.
SIMPLEST ANTI-THEFT DEVICE
What devices are invented so that the attackers couldn’t steal a car. Steering lock, gear shift knob, wheels, dodgy electrics off, the impact on the psyche of a siren, light shows and much, much more. And yet… the thefts occur. Stealing not only expensive cars, but even battered “Lada”, causing their owners considerable surprise. However, on an old car much less you can find modern luxury anti-theft system. And then the interests of the owner and the thief, alas, partially coincide: the first do not want to spend extra money to protect an old car, and the second is happy to steal, because the old man from the automotive industry “leave” on the black market on their own.
