At home, when everything is at hand, everyday problems are solved easier, can not be said about camping life in the campaign – be it a tourist, a geologist, surveyor. Here often helps advance preparation or resourcefulness, the ingenuity, so necessary in a so-called field conditions.
IN THE GROUND — BUT FROM THE POT
The one who had the opportunity to admire the sprawling tent amazingly beautiful flowering shrub clematis, will not stand the desire to have such a miracle and the outside the house or in the country. And if you managed to buy the seedlings in the pot — not necessarily to get rid of it when Read more…
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.
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.
