It would seem that can be the total electric drill hole puncher, washing rubber (eraser) and a paper clip? But O. Lavrov, who considers himself a graduate of our magazine, was able not only to see it shared, but make stationery to work successfully in a number of original technical solutions. As a result of normal (and battered) drill inquiring of homebrew has expanded its typical “drill-tocil-wide” function. Now she can, if necessary, and tighten screws to Unscrew, and if you really itch — even a jigsaw or hacksaw would work tolerably well. All you need is the right tooling (this material is not considered).
STATIONERY IN… DRILLS
Thank you so much, friend magazine, for the development of welding transformers. Inspired by the publications took a chance and made themselves compact, but quite powerful “svarochnik” based on “on the margins” of the burnt stator from a induction motor. Now that dream is about as good design of the rectifier… help me out, dear journal. On you one hope!
Industry now available good double wire with PVC insulation, which occupies when winding on the bobbin a little space. So there is no need to do cumbersome carrying, about which the magazine wrote some time ago. However, the idea Tihonovich from Kharkov (“modelist-Konstruktor” No. 10 of 1985) good. So I decided to develop it further, making the appropriate changes.
Happened that my electric “Rossiyanka-2” went out on one of the switches controls the degree of heating burners. So much so that no restoration is not subject. A suitable replacement for him even in a repair shop not found. Rescued… the thermostat of the burnt iron. However, had a bit to accommodate this, tuscawilla in storage, site.
Industries is not only “pedal” means of transportation and sports equipment to strengthen leg muscles. In the right hands it is easily converted into a variety of small-scale mechanization, as “modelist-Konstruktor” has repeatedly been told on its pages (№ 11’81, 3’85, 2’87, 7’96). And therefore development, are addressed to cyclists — and fans of night riding with brightly burning (alternator) spotlight, may be useful to other readers.
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.
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.
