After a few years of correct operation your drill is the drill started to “MOPE” – ends quickly charge the battery (battery), has to be frequently charged, and for this to interrupt your work. Losing battery capacity is inevitable with heavy use (depends on the amount of discharges-charges) and over time. By the way, if the drill is rarely used, the battery capacity is also reduced by itself (especially if it is stored uncharged), and a year later, may be reduced by a quarter or more. But in many cases, this occurs prematurely because battery other dangers face. So, it will inevitably deteriorate if you apply the tool when the ambient temperature is below 0°C and above +50 °C and in rainy weather and damp conditions, especially if spilled into the water.RECOVERABLE BATTERY DRILLS

Observance of measures of fire safety is necessary for everyone, always and everywhere: at work, at home. And if the companies behind this control is performed by fire supervision bodies, in houses — all this, entirely, entrusted to the tenants.
In our days the number of cell phones in the country has already caught up with its population. This means that each family now for three or four cell phone. Respectively, the same and chargers — because every manufacturer equips your phone only for it intended charger. Well, each charger requires a power outlet — preferably in a place where you can gently place the phone. Oddly enough, but in an ordinary apartment, these places are not so much.
In the construction of houses large rooms usually equipped with a harness that allows you to turn the lamps (for example, shesterikova) in series two, four and six lamps. At the same time in smaller rooms (bedrooms, children’s) posting are only designed to turn all lamps chandeliers. However, in such rooms sometimes want to include only part of the lamps of them.
Want to lead a conversation about “retraining” relatively useless or obsolete electronic devices in the useful and necessary. A lot of stuff gathering dust “in the bins” radio Amateur may get a second life. This is especially true in economically crisis periods, and not only the world but also a family. For example, a portable radio (transceiver) citizen’s band (CB), shown in the photo, are unlikely to even be interested in Amateur radio.
There are various electronic devices to locate hidden wiring. However, at home the need for them arises relatively rarely, when, for example, produce the repair of the apartment or change the interior.
The electronic device described in mi readers, you can install on the toy, equipped with a separate drive for each caterpillar: tank, lunar Rover, Lunokhod. The model moves with headlights on in a darkened room, and set PA her the photodiodes capture the reflection of the headlights from obstacles. The appropriate commands to the drive engines on the basis of the received data takes the logical unit. Here’s how it works.
Small red-hot spiral, fed by electric current, in skilled hands becomes a kind of pencil, which is burned on the tree. This elektrovyzhigatel. For its production you will need a transformer, step-down the voltage to 220 V to 2-4, 1.5—2 m stranded wire (cord), electrical tape, nichrome wire Ø 0,5—0,8 mm with a length of 60-80 mm, wood 30 mm 0 blank or cut of the PCB [plywood] with a thickness of 7-9 mm, screws and M3 nuts, small screws, strips of brass of 1 mm thickness, twine. We offer our readers two versions of elektrovyzhigatel, and each is characterized by simplicity, reliability and safety in operation.
Just 30 minutes will it take to build a simple and reliable time switch that at a given point (in the range of 1-11 h) will switch on or off any home appliance power up to 0.5 kW. The device is made on the basis of a conventional mechanical clock, for example, “amber”, “Sevani”, “Ray”, in a plastic case of which a simple device consisting of two neon lamps T-0,3, a pair of resistors VS-0,25 or MLT-0,5, the micro-switch MP-1, socket for standard plug and fuse.
“Voiced” model tractor, car or locomotive immediately “alive”, if you supply electronic simulator sound. The scheme of the device, imitating the “voice” of the internal combustion engine, printed Yugoslav magazine “Radioamator”.
