At my house, for example, these range from “krohotulki” for work with microelectronics to powerful “ax” with which to patch a leaky metal tanks, repairing wells, filters and other large items. Moreover, the heating element of each electrical device is… the appropriate power resistor (type PE or PEV), powered by household outlet voltage is 220 V. the resistance, if they cannot be avoided, reactive, precise, capacitive, allowing to solve very complex electrical problem with the minimum dimensions of the devices.
THE SOLDERING OF THE RESISTOR
One of the inconveniences in the design of many cars is that the interior light goes out immediately when closing the doors. There are, however, a special device to delay the power light on 5-15 that the driver had time to explore the dashboard controls and to insert the ignition key.

Familiar, perhaps, to every household situation: podklyuchayut all household appliances, which is in the apartment, but in the end — tube on the flap burn out from overload. More precisely, due to the excessively increased current in them melt, breaking the electrical circuit, a special low-melting insert and safeguard wiring from the further heating and ignition. Save these simple, in General, the devices and from large troubles in the so-called short circuit due to insulation breakdown, the inclusion of faulty electrical equipment or in the course of work on nabestaanden (particularly dangerous and inappropriate!) sockets, lamp cartridges, etc.

Since the house has antique samovar, a sin not to use them at least on special occasions. You can even with the ignition not to bother, but just ready with boiling water, poured inside. At first, I did not yet matured the decision to equip this relic of a tubular electric heater (Teh), while maintaining almost unchanged the appearance of the samovar and the basis of its unique design.
On occasion purchased a portable led flashlight in China with the battery inside. The flashlight has the ability to switch between a cluster of eight super-bright LEDs and a krypton bulb for a voltage of 5.4 V. Inside there is also a charger for the battery. In addition, the lamp is combined with a lamp – a fluorescent light with a power of 6W, powered by using a special voltage Converter 150 – 6th Century
