In order not to keep the additional wiring to connect the auxiliary electrical appliances at work using portable lamps, enough cartridge “carrying” to install a homemade adaptor as shown in the figure. For the manufacture of the adapter is used the lighting cartridge, in which are drilled three holes: one in the bottom under peeled from the glass and glue the cap the blown bulbs and the two side under the plug. Before you glue the base with epoxy resin in the bottom, it is soldered from the inside of a flexible insulated conductor with a length of 45 — 50 mm.
THE OUTLET IN THE CARTRIDGE
It often happens that the collective TV antenna is not working properly. In our high-rise building, for example, to take a high-quality image with such antenna only one TV channel. At other rescues antiquated room, which involves, unfortunately, a number of disadvantages.
Anyone, even a well-equipped modern machine shop to do probably without soldering. And no matter how they fought for the engineering is still in front of us (according to the definition of “Explanatory dictionary of the live great Russian language” V. Dahl) — “iron of different types, in a wooden clasp which is kindled, and, holding it across the metal and tin solder first.”
Lighting house number and street name in rural areas – is not an empty whim, but a basic necessity. In dark time of day the postman will be able to deliver a telegram, and RAM service come to the rescue. This is especially useful when the backlight lights up automatically at dusk and does not require human intervention. To make such a device might, perhaps, everyone is familiar with the basics of electrical engineering.
Advantages of welding machines DC before they “perimentally brothers” is well known. It’s mild arc, and the ability to connect thin-walled parts, and less spatter, and the lack of nepreverjenih sites. Even the annoying (and, as it turned out, bad acting people) cod is not. And all because there is no major inherent to the welding apparatus of the alternating current feature — intermittent arcing at the overflow of the sinusoid of the supply voltage through zero (Fig.1).
I recommend readers of the magazine is easy to count, easy to manufacture and very reliable electric soldering iron. 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.
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. But these developments are usually complex and expensive. And reliability often leaves much to be desired.
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.
Outfitting your bathroom under the bath, he decided to make a strong (about 3 — 3.5
The so-called “mouse” is an integral part of a modern computer. With the advent of new, old, still working, but outdated morally, as a rule, thrown away or gathering dust idle in the pantry. However, they can be used practically without changing the electronics. Make it a snap.
