Recently born, the guitar has managed to acquire its own history. At first it was a simple hybrid between a conventional housing with a wiring diagram. Then came the so-called “Board”: the whole guitar was a actually one exaggerated upper deck. “Board” has received the widest distribution in the world… and gradually disappointed many musicians.

EMBED YOUR DIGITAL
Unfortunately, on vehicles of most episodes of “Zhiguli” are not put neither ammeters nor voltmeters, although sometimes there is an urgent need to monitor the battery condition. Produced by the same industry switches instrumentation is bulky and unsightly, and the price is commensurate with the price of parts developed by me homemade digital voltmeter that allows you to control the system voltage in the range of 10-16,3 V, accurate to 0.1 V.
TECHPROGRAM RADIOPROTECAO
People sometimes just have no time to twist knobs of the receiver to switch from one frequency to another. Here comes the advance settings of some of the most popular stations, pressed a button and listen to the desired program. In this mode you will be able to work any long-wave radio with a homemade console, designed for several fixed frequencies in the range of SV.SPEAKERS IN A HURRY
Existing acoustic system (as) furniture type mostly rather cumbersome and expensive. To use them when testing and setting the audio uncomfortable. And in ordinary surroundings while listening to the radio and music are often given preference more simple and accessible to speakers of small capacity, including homemade, produced from scrap materials.The reasons for the failure of the Ipad
Many people when buying a new and advanced gadget I hope for a long life, but in reality it is not so. Due to the fact that the tablets are technically complex device that causes of failures can be many.
WHETHER “CYBER” TRANSLATOR?
Units, tens, hundreds, thousands… This system of accounts, familiar with first class, it seems to us the simplest and most convenient. However, the decimal system is not the only possible one and not the universal. To write numbers in the binary system needs only two digits: 0 and 1. This is a big advantage system, binary compared to decimal. Thanks to her computers and cybernetic devices have their own language that was ideally suited for electronic circuits, relays, diodes, transistors.BYLINA: COLOR AND MUSIC
(The end. The beginning see in number 1). Last time we talked about electromyographical and the stereo amplifier is a musical complex. Today we will talk about it “Svetogorska” equipment.
WIRELESS MICROPHONE VHF
Wireless microphones VHF with frequency modulation (FM) is very convenient when you need to organize one-way communication over a short distance. For example, between residential and utility rooms, parents and children in the yard, and between the crews of the vehicles, the business partners in the market, aid in the organization of cultural activities etc. is Indispensable these compact electronic device when capturing and listening to sounds in nature, as between the information source and the recipient occurs distance, largely conditioned by the “range” used VHF radio.Electronic metronome
“beats” the beats not only sound, but light pulses. In his scheme includes two transistor of different conductivity. The excitation amplifier is implemented by using positive feedback through the capacitor C1. The pulse repetition frequency — from 40 to 210 per minute — adjust the variable resistor R2. The amplitude — adjusted with resistor R5.A simple voltmeter
measuring constant voltage value of 100 V. It is produced by the bridge circuit for the transistors T1 and T2. In one diagonal bridge included a measuring device in the other power source.
