How to test an optocoupler

noreply@blogger.com (Anonymous) — Sat, 18 Jan 2014 16:54:00 +0000

An optocoupler or optoisolator, is a device that contains a light-emitting diode (LED) and a photosensor ( photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc ). The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

Here I want to show you how to check if an optocoupler is working. So i chose one of the most commonly used optocouplers ( PC123 – 4 pins) for the demonstration, but you can use the same principle for all optocouplers ( note: check the device datasheet first ).

Step 1

Using the diagram in the right identify the pins; first the anode and cathode of the LED ( in this case pins 1 and 2 ), and then using an ohmmeter set on the ‘X1 Ohm’ domain, measure between pins 1 and 2, and you should get one reading measuring one way and no reading the opposite way (just like you measure a diode). If you get a value either way or no value at all, then certainly is a problem with the LED, and you should find another optocoupler.

Step 2

If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 and 4 ( the emitter and collector ), and you should get a high resistance value both ways if the phototransistor is good, if you’ll get no reading at all, is probably because most phototransistors have such high resistance between emitter and collector that the ohmmeter can’t measure; if this is the case you could connect in series two meters thus increasing the measuring domain; …although i think most don’t have two meters so i recommend the ‘empirical’ method, presuming you have a variable DC regulated power supply.

Empirical method

Connect the ohmmeter ( X1K Ohm or X10K Ohm ) between emitter and collector ( 3 and 4 ) like this: red probe to collector and black probe to emitter. Now connect a resistor of a few hundred ohms ( ~300 ohms ) in series with the LED anode, after this turn on the power supply and start increasing the voltage from 0 to 2…3 volts, and you should be able to see on the ohmmeter how the output resistance decreases as the input voltage increases and viceversa.

مايكل فاراداي مخترع الدينامو الكهربائي

noreply@blogger.com (Anonymous) — Sat, 23 Nov 2013 01:34:00 +0000

الاسم مايكل فاراداي
ولد في 22 سبتمبر 1791 نيوانغتون بوتس، سري، إنجلترا
توفي في 25 أغسطس 1867 (العمر: 75 عاماً) محكمة هامبتون، سري، إنجلترا
مكان الإقامة إنجلترا
الجنسية إنجليزي

من هو مخترع الدينامو الكهربائي مايكل فاراداي

هو عالم كيمائي وفيزيائي إنجليزي. وهو من المشاركين في علم المجال الكهرومغناطيسي والكهروكيميائي.

اين درس مخترع الدينامو الكهربائي

من أسرة فقيرة فقد كان واحداً من أربع إخوة ولم يتلقى إلا النذر اليسير من التعليم الأساسي فعلم نفسه بنفسه.

عمل صبياً في دكان لتجليد الكتب وهو في الرابعة عشرة من عمره وخلال سبع سنوات قضاها في هذا العمل كان قد قرأ العديد من الكتب من ضمنها كتاب "تحسين العقل" لمؤلفه إسحاق وات.

درس فرداي المجال المغناطيسي على موصل يحمل تيار كهربائي مستمر وبذلك وضع أسس الكهرومغناطيسية.

وهو مكتشف نظرية المحاثة والنفادية المغناطيسيةوقوانين التحليل الكهربائي.

وهو القائل بأن المغناطيسية تؤثر على الأشعة الضوئية ووضع أسس الربط بين هذين الظاهرتين.

يعد اختراعه للأجهزة الكهرومغناطيسية بداية لتكنولوجيا المواتير الكهربائية.

وبذلك يصير أول من جعل الكهرباء شيء عملي لاستخدام التكنولوجي.

ويعتبر فاراداي أول من إكتشف البنزين

وأما فرداي كعالم كيميائي فهو أول من إكتشف البنزين. ودرس مسألة هيدرات الغاز وأخترع آلة حرق البنزين وهو من أطلق ألفاظ المصعد والمهبط والقطب والأيون.

رغم أن مايكل فرداي لم يدرس الرياضيات في المدارس غير القليل منها إلا أنه كان عالماً فذاً حيث صٌنف أنه من أعظم العلماء في التاريخ. ففي نظام الوحدات الدولينقوم بحساب قيمة المكثف ونقيسه بوحدة الفاراد على اسمه أي مايكل فرداي.

وكذلك هناك ثابت فرداي أيضاً سمي على اسمه والذي يساوي 96,485 كولومب وهوشحنة المول الواحد من الإلكترونات.

كما سمي باسمه قانون فرداي للحث الذي يقول بأن تغير المغناطيسية في الزمن ينشئ قوى كهربية محركة. كان فرداي هو أول من نال منصب Fullerian Professor of Chemistry في المؤسسة الملكية الكبرى ببريطانيا. كان فرداي مسيحياً متديناً وكان عضواً في كنيسة ساندمنيان.

المحولات الكهربائية الجزء الأول

noreply@blogger.com (Anonymous) — Sat, 23 Nov 2013 01:31:00 +0000

بعض الانماط الرئيسية للمحولات ...... الجزء الاول
تستخدم المحولات لمجموعة كبيرة من الاغراض مع مجال واسع لتنوع قيمة الجهد وتصنيفات القدرة فضلا عن العديد من المزايا الخاصة لتطبيقات معينة
سنستعرض في مقالين منفصلين الانواع الرئيسية الاكثر شيوعا والاكثر استخداما

- المحولات المستخدمة مع الاحمال الالكترونية :
المحولات المستخدمة للدارات الالكترونية او لتزويد الطاقة بالجهد المنخفص تعد احد التطبيقات الخاصة للمحولات تستخدم ليتم التطابق بين الجهد المقدم من قبل الشبكة مع جهد التشغيل للمعدات الالكترونية

- المحولات الصغيرة :
تستخدم عادة مع وحدات تزويد الطاقة الثابتة والمتنقلة او حتى المحمولة باليد وتستخدم ايضا كعازل وتطبيقات خاصة اخرى
يمكن استخدام هذا النوع لتزويد قدرة بشكل ثلاثي الطور باستطاعة تصل حتى 40 KVA وتردد حتى قيمة 1 MHz
يتم استخدام الهواء عادة كمادة عازلة في هذه المحولات كما يتم استخدام اسلاك مطلية بمادة المينا ونوى حلقية
السلامة هي مصدر قلق كبير لهذه المحولات لذلك يمكن تصنيفها من حيث الحماية الى 3 اصناف
الاول مجهزة بوحدات محمية من قبل محطة ارضية
الصنف الثاني يحتوي على عزل بشكل مضاعف اوما يسمى بالعزل المقوى
الصنف الثالث يحتوي على مخارج سلامة (SElV) اقل من 50 فولت متناوب و 120 فولط مستمر

- محولات التوزيع :
يستخدم هذا النوع من المحولات في توزيع القدرة الكهربائية للأماكن المحلية والمنشئات الصناعية والتجارية,يمكن ان تكون احاية او ثلاثية الطور
ويمكن ان تعتمد مبدأ الاقطاب المحمولة (المرفوعة عن الارض) او الاقطاب المحمولة على الارض
لديها مجال واسع للعمل يتراوح بين 16 KVA و 2500 KVA
تستخدم الزيوت كمادة اساسية للتبريد حيث تكون الاسلاك والنواة مغمورة بمجموعة من الزيوت المعدنية لتأمين التبريد اللازم
يوجد على كل طور ملفين الاول ملف ابتدائي يطبق عليه الجهد المرتفع بمجال يتراوح بين 3.6 kv ال 36 kv
والثاني يدعلى بالملف الثانوي يطبق عليه الجهد المنخفض بقيمة لا تتجاوز 1.1 kv
تكون نوى واسلاك محولات التوزيع النموذجية من صنف ال 800 KVA

- محولات التزويد بالقدرة :
تستخدم عادة لتزويد منشئات او مباني صناعية كبيرة او محطات التوزيع بمجال عمل يتراوح بين 4 MVA الى 30 MVA بتقدير 66 KV لأسلاك
الملف الاولي و 36 KV لأسلاك الملف الثانوي
تعتمد عادة على المواد السائلة للتبريد (زيوت معدنية) لكن في بعض التطبيقات مثل منصات النفط وبعض المصانع يمكن استخدام السيليكون السائل او بعض السوائل الاخرى مع نقطة اشتعال اعلى من الزيوت المعدنية

- محولات النقل :
يعد هذا النوع الاكبر بالحجم والاعلى بقيمة الجهد بين المحولات حيث تستخدم لنقل القدرة الكهربائية في شبكات التوتر العالي بمجال عمل
يتراوح بين 60 MVA و 1000 MVA
يتم استخدام الزيوت المعدنية في عملية التبريد بشكل رئيسي وتكون محولات النقل عادة مزودة بمضخات زيتية ومراوح للمبردات للمساعدة في عملية تبريد الملفات والنوىش

الصمام الثلاثي ( صمام ثلاثي الاقطاب )

noreply@blogger.com (Anonymous) — Mon, 15 Apr 2013 22:26:00 +0000

شرح الصمام الثلاثي من طلب الأخ الكريم

( Mustafa LOST )

الصمام الثلاثي :

سمي بهذا الاسم لأنه يحتوي على ثلاثة عناصر ( أساسيه ) هما المهبط والمصعد والشبكة .

تركيبة :
1 – مهبط (cathode ) قطب سالب يبعث الإلكترونات .
2 – مصعد (anode ) قطب موجب يستقبل الإلكترونات ( صفيحة معدنية ) .
( يُسمى المهبط والمصعد بالقطبين الكهربائيين ) .

3 – شبكة ( drain ) تتحكم فى سرعة الإلكترونات .

4 – أنبوبة زجاجية مفرغة [غلاف زجاجي أو فلزي أنبوبي الشكل ] .

طريقة عمله :
1- عندما يكون جهد الشبكة (صفر) يعمل كصمام ثنائي .
2- عندما يكون جهدها (موجب) تزداد سرعة الإلكترونات (للجذب) .
2- عندما يكون جهدها (سالب) يزداد تدفق الإلكترونات (للتنافر) .

استخدام الصمام الثلاثي :
يستخدم الصمام الثلاثي فى تضخيم الجهد ويحسب معامل التضخيم من العلاقة :

معامل التضخيم = تغير جهد المصعد / تغير جهد الشبكة

ما عيوب الصمامات الإلكترونية المفرغة ؟
1) كبيرة الحجم.
2) تستهلك مقداراً كبيراً من الطاقة الكهربائية.
3) سرعتها بطيئة جداً.
4) سهولة كسرها .

Led Running Lights

If you are looking for the miniature running LEDs light then here you can get one. The circuit in this site is is using the timer 555 1 to 10 decoder 7493 and 1 to 16 decoder 7441.

PART LISTS

**RESISTORS**
R1	6.8k
VR1	100K
R2, R3	220 Ohm

**ICs**
IC1	Timer 555IC
IC2	1 to 10 Decoder 7493 IC
IC3	1 to 16 decoder 7442 IC
(N1,N2) IC4	IC 7400 – NAND Gate

**DIODES**
D1 – D16	LEDs

**OTHERS**
C1	Capacitor 5μ 25 V
C2	Capacitor 0.01μ
BATT	Battery 5 Volt

Circuit Diagram

The circuit consists of three parts. The first part has an oscillator while the second has mod 16 counter 7493. The oscillator is wired in self-triggered mode, and the potentiometer VR1 is used for speed control of the running lights. That is, frequency can be varied from 21 Hz to less than 1 Hz.The counter outputs A, B and C are decoded by IC3 (the decoder 7442) and the outputs obtained on pins 1 to 9 of this IC.The D output of the counter is used for selecting the LEDs from D1 to D8 or D9 to D16. When D is low D1 to D8 are selected, and when D is high D9 to D16 are selected.For the selection of these LEDs, IC4 (7400) NAND gate is used. Thus, a sequential running effect is produced.

Sunrise Faucet

noreply@blogger.com (Anonymous) — Thu, 24 Jan 2013 02:35:00 +0000

Sunrise Faucet concept gives us a glimpse of what should look like the valves tomorrow. A day which does not seem very far since prototypes have already been made.

Sunrise Faucet with his winged form and take the valve plate into another dimension. Exempt from any mechanical part, this faucet is decidedly high-tech 100% multitouch. On one of its "wings", it displays five touch buttons. Thus, some fingering, the user can control the temperature or the flow of water. It was also right to ON / OFF button to turn off the tap when not in use to avoid wastage. With a decidedly innovative design, ultra modern and sophisticated form of Sunrise Faucet is an added bonus for this cock like no other.

The designer of this futuristic faucet Stefano Ollino Doro Design. The concept already has two major awards to its credit: a IF Design Award and a Red Dot Design Award.

THYRISTOR AND TRIAC TESTER

noreply@blogger.com (Anonymous) — Tue, 27 Nov 2012 11:42:00 +0000

THYRISTOR AND TRIAC TESTER

Occasionally   with these components   doubt arises we work correctly, especially when we are repairing an appliance and also sometimes when we try to recover any items of equipment   already disused or damaged.

The problem is that with the multimeter   We can only check if shorted or open not know   you switch   correctly   in the case of thyristors is unidirectional check   (CC)   and checking the triac   (CA) is bidirectional because the latter are designed to work with alternating current.
In these compounds the pinout is almost standard (such as MOSFET), for this reason the design of the tester has   arranged order of the socket contacts match the order of most   pin thyristor and triac, this does not mean that some do not have a different order depending   Manufacturer and model checking component, a recommendation should always check the characteristics of the   component and its pin layout   to avoid mistakes.
Within the family of thyristors and triac as with other semiconductor devices exist some   with special characteristics in the case of these components include those with a high sensitivity of shot (Igt in mA), as examples of the common model triac   BTA 10-400 with Igt from among   25 to 50 mA   a thyristor and the other one Igt X0402 with less than 200 μ A. although the latter are less common with that caution should be used when the measure because of its high sensitivity to gate the tester may indicate a component wrong, a simple check of the characteristics of this component can save us problem.

Driver Reviver Features

Driver Reviver ensures all your hardware devices and software applications are performing at peak performance levels. Missing out on the latest driver releases means your PC and hardware devices are being cheated from bug fixes, performance improvements, and potential new features from the manufacturer.
Saves you time. It will require numerous hours to track down each and every driver for every single piece of hardware connected to your PC. Driver Reviver accomplishes this in minutes.
Saves you money. There are driver sites that provide drivers on a 'cost per download' basis. Your system will likely require hundreds of updates in its lifetime, so this option is expensive. In contrast, the number of drivers you can download using Driver Reviver is limitless during the subscription period.
Prevents you from incorrectly using the wrong driver. Drivers are hardware-dependent and operating-system-specific. This means that drivers (1) must be compatible to your PC's operating system, and (2) be suited to your hardware's brand and model. Driver Reviver automatically works on this basis so you're assured that driver update recommendations are specific to your system and hardware.
No need to be tech-savvy. It takes a bit of PC knowledge to scan for drivers, download them, and install them properly. Driver Reviver does all this for you.
Finds the right driver straight from the manufacturer directly. There is no need to hunt for the original installation CD or wasting time trawling the web.
Completely reduces your risk of downloading a faulty driver or even spyware. The wrong driver or malware could render your PC inoperable and potentially put you at risk of identity theft.
Driver Reviver protects you from mistakes. Restore point setting ensures that if there are any problems with an update, the changes can be easily reversed to get you back up and running in no time.
Huge database connected directly to the original manufacturer. Driver Reviver has over 10,000,000 drivers and applications from 56,000 hardware and software vendors.
New intuitive and simple to use interface makes Driver Reviver user friendly and easy to use. Driver Reviver has been developed with the novice user in mind while providing the backend structure and functionality expected by the most advanced user.
Light footprint ensures your computer's performance won't be affected while you use Driver Reviver. The last thing you want to do when running an application is for it to bog down your system and lose performance. Driver Reviver is all about helping improve your PC's performance and has been developed with this in mind.
24/7 technical support. Support for Driver reviver is available from within the product and via email. Turn around time for a support request is less than 2 hours.
Driver Reviver is RISK FREE. If for any reason you are not satisfied with your purchase, simply contact our friendly consultants within 30 days, and we will happily give you your money back.
Windows 7 compatible. Many driver updaters are not yet Windows 7 compatible. With the big push for Microsoft on this launch, and with most new PC's coming with Windows 7, the need to be able to update software and drivers for existing peripherals for Windows 7 is extremely important.

Circuit Analysis with Multisim

noreply@blogger.com (Anonymous) — Sat, 11 Aug 2012 23:10:00 +0000

Description:
This book is concerned with circuit simulation using National Instruments Multisim.
It focuses on the use and comprehension of the working techniques for electrical and electronic circuit simulation.
The first chapters are devoted to basic circuit analysis.
It starts by describing in detail how to perform a DC analysis using only resistors and independent and controlled sources.
Then, it introduces capacitors and inductors to make a transient analysis.
In the case of transient analysis, it is possible to have an initial condition either in the capacitor voltage or in the inductor current, or both.
Fourier analysis is discussed in the context of transient analysis.
Next, we make a treatment of AC analysis to simulate the frequency response of a circuit.
Then, we introduce diodes, transistors, and circuits composed by them and perform DC, transient, and AC analyses.
The book ends with simulation of digital circuits.
A practical approach is followed through the chapters, using step-by-step examples to introduce new Multisim circuit elements, tools, analyses, and virtual instruments for measurement.
The examples are clearly commented and illustrated.
The different tools available on Multisim are used when appropriate so readers learn which analyses are available to them.
This is part of the learning outcomes that should result after each set of end-of-chapter exercises is worked out.

RoboCup 2012

noreply@blogger.com (Anonymous) — Thu, 28 Jun 2012 01:18:00 +0000

RoboCup objective:
It is our intentions to use RoboCup as a vehicle to promote robotics and AI research, by offering publicly appealing, but formidable challenge.

One of the effective ways to promote engineering research, apart from specific application developments, is to set a significant long term goal.

When the accomplishment of such a goal has significant social impact, it is called the grand challenge project.

Building a robot to play soccer game itself do not generate significant social and economic impact, but the accomplishment will certainly considered as a major achievement of the field.

We call this kind of project as a landmark project.

RoboCup is a landmark project as well as a standard problem.

The Dream:
We proposed that the ultimate goal of the RoboCup Initiative to be stated as follows:
By mid-21st century, a team of fully autonomous humanoid robot soccer players shall win the soccer game, comply with the official rule of the FIFA, against the winner of the most recent World Cup.

We propose that this goal to be the one of the grand challenges shared by robotics and AI community for next 50 years.
