5 ثورات تكنولوجية عملاقة ننتظرها في 2018
تنتظرنا الكثير من المفاجآت في عالم التكنولوجيا في سنة 2018. هذه «الثورات العلميّة» ستكون على هيئة اختراعات وتجارب تُقام لأول مرة في 2018، أو ستُعمم لتصبح تكنولوجيا شائعة قادرة على تغيير وجه العالم كما نعرفه إلى الأبد. لن يكون توقعنا مبالغًا فيه إذا قلنا بأن استمرار هذا التقدم التقني والتكنولوجي سيكون سمة أساسية في تشكيل مستقبلنا ومستقبل الأجيال القادمة على الكوكب. في هذا التقرير، نعرض خمسة اختراعات نتوقع أن تكون لها تأثيرات هائلة في نظرتنا للعالم، وفي تشكيل طريقة حياتنا في سنة 2018 وما بعدها.1-الأجِنَّة الاصطناعية.. تصوّرات جديدة لبداية الخلق!نجح فريق من علماء الأجنة بجامعة كامبريدج البريطانية..
Android BLE User Guide

If you are an electronics enthusiast, and also fond of programming, I would be very glad to share with you an Android BLE application development method, so you can integrate the phone and MCU to do some more interesting things. Right now we begin to explain how to develop an Android BLE application, and you can also refer to the official Google tutorial . This guide is a packed tutorial, which enables you to build your Android BLE application more easily and more quickly. Of course, I’ll upload my source code for everyone to share it and you can also refer to the official sample sdk/samples/android-18/legacy/BluetoothLeGatt.

ELECTRONICS STREET LIGHT SWITCH
Here is a simple, expensive and easy to use electronics street light switch using LDR and NE555. The working of this circuit is truly based on light sensing, i.e. automatic turn it on in night (no sunlight available) and turn It off at sunshine (sunlight available).Circuit Description of Electronics street light switchAs electronics street light switch is a switching circuit so, for more detail we can divide this circuit into two section i.e. power supply and switching circuit.In this power supply section the work of step-down transformer is done by register R1 and further rectification t..
Varistor
Varistor TutorialVaristor IntroductionThe varistor is a passive two-terminal solid state semiconductor device that is used to provide protection to electrical and electronic circuits. Unlike the fuse or circuit breaker which offers over-current protection, the varistor provides over-voltage protection by means of voltage-clamping in a similar way to the zener diode. The word “Varistor” is an acronym, and is a combination of the words VARI-able resi-STOR used to describe their mode of operation way back in their early days of development which is a bit misleading since ..
What is Varactor Diodes?
Varactor diodes or varicap diodes are semiconductor devices that are widely used in the electronics industry and are used in many applications where a voltage controlled variable capacitance is required. Although the terms varactor diode and varicap diode can be used interchangeably, the more common term these days is the varactor diode.Although ordinary PN junction diodes exhibit the variable capacitance effect and these diodes can be used for this applications, special diodes optimised to give the required changes in capacitance. Varactor diodes or varicap diodes normally enable much higher ..
IMPORTANT SAFETY INFORMATION: Microwave ovens are among the most dangerous appliances to work on. Before attempting any troubleshooting, testing or repairs, for your personal safety, we strongly urge you to carefully read the very important safety instruction about how to deal with Microwave Ovens. The high-voltage rectifier (diode) works along with the high-voltage capacitor to effectively double the already-high voltage that is provided by the power transformer. This powerful voltage, about 3000 - 5000 volts DC (depending on the model), is ap..
What is TVS Diodes?
What are TVS Diodes?TVS Diodes are electronic components designed to protect sensitive electronics from high-voltage transients. They can respond to overvoltage events faster than most other types of circuit protection devices, and are offered in a variety of surface mount and through-hole circuit board mounting formats.They function by limiting voltage to a certain level (referred to as a "clamping" device) with p-n junctions that have a larger cross-sectional area than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage.TVS Diodes are generall..
What is a Fast Recovery Diode?
What is a Fast Recovery Diode? A fast recovery diode is a diode which has a quick recovery time.What a quick recovery time is will be explained below.One of the most common applicadtions for a diode is to rectify 60Hz sine waves. This is the frequency of normal AC power lines in the United States. The diode rectifies this current so that it can be changed from AC current to DC current, since most electronic devices work off of DC power. So the diode rectifies this 60Hz AC sine waves so that it can converted into DC. 60Hz is a very low frequency. Most standard conventional diodes are desig..
