On one of the sunny spring days, I took a motorcycle ride. The weather is perfect for motorcycle trips. The big water has already descended, the banks have dried up. Motorcycle Lifan 200 gy-3b class enduro beautifully goes both on the asphalt and off-road. On this motorcycle you can easily overcome several tens of kilometers along a flat road, and then off-road where you wish. The motorcycle is lightweight, weighing only ~ 125kg. If you get stuck, it’s easy to pull it out. At the same time, it easily takes on as much weight. The motorcycle Lifan 200 gy-3b is equipped with a full-size rubber: in front on a 21-inch drive, behind an 18-inch drive. The 200cm2 motor has enough power for driving along the track at a cruising speed of 85km, although it is possible to accelerate faster. The transmission has 5 gears. For the duration of the break-in, I switch speeds at 17 km/h, i.e. at 2nd speed I switch to 17 km/h, at 3 in 34 km/h, on 4 in 51 km/h, on 5 in ~ 60 km/h. Speed ​​is easy to watch on the digital speedometer. If you have any questions, ask, I’ll be happy to answer.

Such curbs met on one of the streets of Kirov. Curbs are granite, made by hand. They show traces of giant drills. The borders were placed on this section of the road about 60 years ago. Each curb weighs from 100 to 1000kg. All the borders have different sizes – length from 1 to 4 meters! We will not repeat each curb. Now they are dismantled from this place. It is a pity that there is a replacement of the eternal natural materials for not durable and cheap.

I decided to make an extension cable from unused cables. These cables lay for many years in the pantry. Initially, they were intended to power servers. The plus of this cable is that it is in double thick insulation, and has 3 wires. The cross-section of each wire is 0,75mm2. We do not use a ground wire, so I connected it to another wire. Most importantly – do not forget to dismantle the “Grounding” contact in the plug. The total length of the resulting extension was more than 10 meters. The extension cord will undoubtedly find application in any farm, especially – it is pleasant to use a thing made by own hands.

Teaching telegraph key. There is such a telegraph key, produced by the USSR. The key has a convenient but not reliable adjustment, since screws are used in the adjustment with standard thread and pitch. There would be screws with a shallow step, it would be much better and more convenient. The manipulator is resilient, although it is made of a thin metal strip, without facets. At the handle of the manipulator is a handle, with a composite skirt. The skirt is made of cardboard. Sometimes the skirt leaves its native place or bends, it takes a skirt to make a new one.
