Japanese car Mitsubishi lancer of 2007. Continuous update — here is one of the main principles of creation of high-tech consumer products. Constantly decreasing period of the market entry of new improved cameras, mobile phones and more productive computers. Is not time consumer is to buy “the best of” the perfect digital video camera or pocket PC, as a manufacturer throws on the market a new model with better consumer qualities, leaving the buyer with the “old”, released only a year ago an electronic device on hand.

Built-in furniture for country attic. As a rule, country attic (the so-called well-maintained loft happy owners shestietazhnyj plots) — the room is not too large, so that linen cupboard and a couple of beds can take most of it. Meanwhile in the attic for placement and cabinets, and beds it is possible to use the volume located between the sloped roof slopes and vertical walls.
When installing the radio a lot of time to spend on processing wires. First of all you need to remove the insulation, clean, tinned with stinging, and then proceed to soldering. Except for this the soldering iron, necessary lies, cutter and blade. And together with the isolation often cuts off part of the wire cores, n then have to start all over again. I propose a simple adaptation to the soldering iron. The eye eliminates unnecessary hassle, save time, improve the quality of construction works.
Radio, about which we tell, collected under the scheme direct gain works in long ranges (2000 — 740 m or 150 — 400 kHz) and medium (200 — 550 m or 520 — 1600 kHz) waves. Despite its relative simplicity, it has a sensitivity sufficient for admission to the internal magnetic antenna stations, remote distance up to 250 — 300 km With outdoor antenna reception range even more.
Depicted in the drawing bath is designed for apartments where there are no special facilities. “Hiding” it in a wooden Cabinet, made according to the dimensions of the bath. The box itself is assembled from particle Board with a thickness of about 20 mm, on the outside it is coated with synthetic film “under the tree” and inside: “tile” with tiles.
To calibrate, to establish or verify the performance of the radio equipment in the frequency range of 1-75 MHz allows this device. His scheme (Fig. 1) comprises a generator-the”type” with capacitive connection is made to the transistor V1. The oscillator frequency and its harmonics determine the replacement of quartz resonators B1, connected via
Homemade mikromototsikly built using bicycle parts and children’s scooters, gaining among our youth is growing in popularity This is quite natural: a miniature car garage is not needed, it can be kept even in the apartment; its cost (both initial costs and maintenance costs) is very small; learn how to manage such a machine can be a few hours, and how many interesting trips will allow it to make, especially in the countryside!
In the fourth issue of the journal for the year 1978, published schemes of electric locks with a “secret”. They all work well, but they, in my opinion, there is one drawback: the locks can not be powered from a DC source. I propose a scheme for electronic lock, the key to which is the resistor. Here’s how it works. When the terminals X1 and x2 (see diagram) connect the resistor R2, transistor V1, the base voltage goes negative, opens and relay K1 is triggered.
