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.
The reasons for the failure of the Ipad
Ham radio
RAM INSTEAD OF ROM
Debugging any program of the microprocessor, it is necessary many times to write and erase information in the chips ROM КР573РФ5 (РФ5). However, the online those is very limited. In the end — quick exit of the chips from the system.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.MALTESE FISH
In the aquarium automation now the dominance of the expensive import, processors, chips, complex equipment… But is it always justified the cost of purchasing the advertised aggressively in the domestic market by foreign devices? And isn’t it better to return to the simple and reliable Russian designs? Among them can be attributed to the proposed technical solution.
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.LIGHTING CONTROLS AUTOMATIC
When lighting and electricity were cheap, the question of cost-conscious approach when choosing lighting stairwells seriously anyone is not intended. But life has taught everyone to count every penny, so convinced of the feasibility of using the machine include a ladder and corridor lighting (ALLCO) there is no need. The question is: which of the many existing developments to choose?WAKE TAPE RECORDER
I designed a digital timer, which wrist watch, MONTANA, has a great standby time (up to 24 hours), good precision (the error is only a few seconds per day), simplicity, performance and small power consumption in the standby mode. The latter allows you to use the timer as a cost effective and pretty original clock. However, the load in this case is used with a tape cassette that is included in the reproduction, or radio receiver, tuned to the station.
