Talking about various musical instruments, it is impossible not to recall the, perhaps, popular and indispensable in modern orchestras and rock bands. Of course, this is the electric guitar.
THE ELECTRIC GUITAR IS OUT OF THE ORDINARY
Himself an electrician
BUCK… EXTENSION
When performing various jobs around the house was sometimes necessary to have on hand a source of electricity with lower than the normal network voltage. For example, to illuminate the water in the tank (to save the bulb from premature burnout of the filament), etc.
INSTEAD OF NEONKI – TIRATRON
Specialists in service and repair of industrial electrical installations will appreciate, I think, a convenient small-sized probe – “kontrolka” on 220/380 V. Indicator is not “neonka”, and the thyratron MTX-90. And as for the case, fit any size transparent (plastic or glass) bottle from under the drugs. Moreover, if the material of the “case” glass, to protect its integrity (for example, in case of an accidental drop) I recommend to wrap the probe in two or three places with electrical tape (in the form of shock-absorbing rings). Well, at the styli wear a PVC tube.
WANTED TO MAKE IRON…
during the period covering the country’s public deficit even the most that neither is ordinary iron burst in a number of regions in the category of “trudnoreshaemyh”. And is — alas! — quite expensive. But for the resourceful craftsman to make the original iron, as they say, no problem. You only need to thoroughly want… unlike the hero of the once popular song where the words are in the title of this material, the success of saadeldin guaranteed.
HAIRDRYER PAINTER
To strip layers of old paint in the repair of the “woodwork” is a handful for the home worker. Apart from the fact that the work is time-consuming and unproductive, it is also a source of debris and dust, which during the repair and without that is enough. There is, however, an easier way to remove the painted surface of the old coating, which involves the use of a gas burner or blowtorch. But use it indoors I would not recommend it at any time paint can erupt, and then the trouble will be inevitable.
THE LAMP WILL SERVE LONGER
As is known, operation at a higher supply voltage, the mode transition processes (with frequent switching on and off) are light bulbs guidelinesin follows: ultimately burns out the filament. Meanwhile, the lifespan of light bulbs can be considerably increased if you connect them to the AC mains via a special adapter, each of which — your… rectifier. Of course, compact: solid-state, half-wave rectified without filter.
ELECTRONIC IGNITION:OPTIONS
We are talking about different versions of electronic ignition devices (UEZ), is made as transistors and IC. The lack of scarce elements, as well as the simplicity of the schemes allow you to collect the block of electronic ignition even ignorant in electronics motorists. UEZ can work together with the ignition coil B-117 (B-117A) and B-115V, used in cars “Zhiguli”, “Moskvich” and “Zaporozhets”, and since there is no special transformer to storage capacitor, the device consumes virtually no current when the ignition is on, has small weight and dimensions.
THE RADIATOR FOIL
Fast and simple — to manufacture heat sinks for transistors and microcircuits made of copper or aluminum foil with a thickness of 0.1—0.3 mm. Plates are cut with scissors, carefully collected in a package with a thickness of 3 mm, clamped between two fairly tough boards and drill holes. Prior to Assembly of the plate trimmed in the area of thermal contact and smooth out the micron sandpaper to ensure their tight fit. And after the plates are assembled, their ends are bred throughout the free zone.
SWITCH-STAND-IN OUT OF THE ORDINARY
In the December issue of “M-K” for 1990 were published material about the switch-gubbare. There is proposed a technical solution I liked, but… think about it, has developed its own version. In order to turn on the light of the two points, sometimes enough to modify the normal switch. It is necessary to disassemble and install a third contact plate. This is done quite simply.
BLUE SOLDERING IRON TIP FOR SOLDERING
My burner — ejector for high temperature soldering. Running from the LPG cylinder. It is economical: the number supplied to the gas ejector can be adjusted. The burner is arranged in the following way. From the gearbox or gate valve on the cylinder gas is fed through the hose to the inlet tube built into the base of the burner. From there it flows through the vertical channel of the rack in the Central bore of the body of the jet, where the amount dosed adjusting needle mounted on the threads of the housing cover. Further, the gas supplied to the nozzle and ejected through the hole.
