It is known that the temperature of the soldering iron depends largely on the quality of the performed installation. Are particularly bad (if not harmful) to overheat. Immediately deteriorating the quality of the soldering, there is a risk of peeling the printed wire Board, is accelerated wear of the operating rod, and even failure of the heating element. Sting often cleaned of oxides and overheated — not holding solder.
Every day we use a huge amount of things and have almost ceased to notice them. But it turns out in the production of minor things at first glance hides a lot of interesting and informative.

“Almost five years are a reader and subscriber of the journal “modelist-Konstruktor”. During this time, produced in any published developments in several homemade “for home, for family.” Would like to start welding-charging-starting device, a circuit diagram and description of which I had noticed in one of the rooms of the journal for this year, but deterred by the winding operation in the manufacture of powerful transformer, choke. And the installation of electronic control unit thyristors, I’m afraid not master. Whether it is at least a little to simplify the development of that interest me?”
For feeding low-voltage soldering iron from a household outlet uses simple adapters, which are, as a rule, the quenching capacitance (capacitor for a specific value). However, the use of such a device for installation of equipment with microprocessors, field-effect transistors and other electronic components afraid of static electricity is undesirable. Too high risk of breakdown due to the direct connection of the heating element with electricity of high voltage. Need galvanic isolation. For example, in the form of a step-down transformer.
No need to be a technician to do such wonderful things. Old vase turned into the original decoration of the interior; a simple clay bowl in the Cup with an elegant geometric ornament; and from the frame out of plywood for a mirror it is impossible to look away. What looks like a set of stories, really — a wooden box decorated with ceramic shards. A clip made of fragments of porcelain and small beads. Good idea for a gift: the same can be decorative pins and brooches.

The once super popular in the narrow circles of the party-state nomenclature Executive car GAZ-13 “Chaika” in the 1960-ies began to lose its appeal. Pretentious machine with the design of the end 1940-x of years, full of airplane fins, chrome mouldings and fanciful lattices, it seemed yesterday the mighty car mods. Artists and designers of Gas tried to pimp the appearance of “the Seagull” (known, for example, modification of the GAZ-13 with four headlights, chicken wire grille and a flatter bumper), however, the initiative of the factory designers were not supported by “surface”.
When worn the seal to the water tap in the kitchen or in the bathroom, constantly begin to leak and drip water. To fix the leak will succeed on their own. For this you need to disassemble the faucet(of course, pre-cutting off water) and remove the worn gasket, replacing it with a rubber cork from Read more…

I am an active participant of many paragliding events and now flying coach. Thus, we have an opportunity to observe the development of paragliding in Russia. And today I can note a brand new trend in our still young sport. The previous ten years of intensive development and improvement of the domes. Now, however, manufacturers have reached a certain ceiling. Relevant are not only the technical parameters paragliding equipment as its cost and availability for those enthusiasts who cherish the dream to fly in the sky like a bird.
