LED FLASHER ( About 1Year )

Image
This is so useful circuit diagram for you Because this circuit can light up an LED about 1 year with 9V battery.Here I have used famous IC HEF 4093. Note # Use a white colour LED # Build this on a PCB to get maximum result # Use 9V battery to power this circuit

What Jobs Awaits for Electrical Engineering Graduates Today?

Image
Let me pause for awhile in posting lectures about Electrical Engineering . Let's have a short talk about the jobs and opportunity awaits for all graduates of Electrical Engineering. Details are fact based on the present situation nowadays and also based on my own personal experienced. According to National Statistics Coordination Board in the Philippines, unemployment rise from 7.5% of April 2009 to 8.0% of April 2010. The most common rise up of this unemployment rate is because of the newly graduates and one of these are the Electrical Engineering graduates. There are approximately about 1,611 newly graduates in the Philippines (Registered for Electrical Engineering Board Exams)which are expected to be unemployed nowadays. Still grabbing for a new job and opportunity that may suit them. In U.S. according to Department of Labor's Bereau of Labor Statistics employment grew for Electrical Engineers by 7.8% from the fourth quarter of 2009 to the first quarter of 2010 and now 16.1%

Electrical Engineering Tutorial Still Alive?

It's been nine months ago when I stopped making a post here at Electrical Engineeering for Beginners. I had received more comments for some other topics I published. I just want to apologized for my very late response. As you know, I'm not a full time writer of this blog related to Electrical Engineering. For this 2010 onwards, I will be making my own website about Electrical Engineering. But that will depend on my time since there are no other support I'm receiving to complete this course outline. As of now I'm busy learning an HTML or the Hyper Text Markup Language and CSS or the Cascading Style Sheets to make a website of my own. Besides, I'm a full time worker in one of the semiconductor company where all my time are being spend only to support my family. For all of you readers out there, good news! this Online Electrical Engineering tutorial will  resume on September 2010. I will continue making a post about Electrical Engineering topics from where I stopped.

9V (2A) power supply circuit diagram

Image
Lots of members asked about 9V dc power supply with 2A.So here We have introduce a new circuit diagram.This circuit can provide 9V 2A.I suppose now you all have some what good power supply with some what good amp level.This circuit operates with famous IC 7809.If I say simply this is a amp booster circuit. Note # Build this circuit on a PCB to get maximum result # If you can attach a heat sink to the IC It will get a long life

Ding Dong Bell circuit diagram

This is a ding dong bell circuit diagram.I have attached this circuit for my house.Even you can use this circuit as an sound generator.When we buy this circuit from the market we have to spend much money but now you can build this your self.Here I have used common Ic Ne 555 and you can operate this circuit with 9V power supply. Note # Build this circuit on a pcb # use 9V power supply to power this circuit # When you deal with 230V be careful
