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.
AND THE SWITCH WILL BEEP IN RESPONSE
An audible alarm on digital microcircuits for switching on/off electronic devices with 12 V power supply. There are many devices in a car that are switched on by a key or a toggle switch. The switching on of a particular device can only be controlled by the click of a mechanical switch (which may not Read more…
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.
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.
Development and manufacture of printed circuit boards for a single instance of a homemade device with a higher density of mounting becomes sometimes a problem even for the experienced radio Amateur. I have also found the opportunity to do without any preliminary layout of printed wiring conductors, and even without soldering electric and electronic circuits. I replace all of that… wrap.
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.
