New book from magazine Elektor: Introduction to Control Engineering. This book provides practical information on hardware and software related to instrumentation and control engineering, illustrated by examples from a range of industries and applications, and also this book contains examples of PIC, PLC, PAC and PC programming.   Elektor subscribers who order the book before [...]

Here’s a project that shows you how to decode a tv remote control’s infrared (IR) signals and make your own IR receiver for it. The receiver decodes the infrared commands sent to it by a remote control, and displays them on an LCD for verification. Source: pyroelectro

How to get 5 volts from a higher voltage?  Of course by LM7805. The fact that the chip is the LM7805 linear voltage regulator. This means that all the excess stress she planted on his. That is, when an input voltage of 12 V, she is forced to provide for themselves a voltage drop of [...]

This mini protoboard you can use for a small project. With this board that you can start with some simple projects such as LED Flaser and progressing on to more advanced projects.   Source: b0j3

Mikroelektronika release a new USB Reg board. USB REG board is a solution for powering your device over USB connection. It gives 5V directly from USB, but also features MC33269DT power regulator circut for creating 3.3V reference. Board is very small and can be easily integrated in your prototype as well as in your final [...]

Today we did an project amplifier with LM386. This amplifier is very easy to make and very compact, works with a single power source whose value can be between 4V and 12V.It is based on the use of a type LM386 amplifier, capable alone to issue a power of several hundreds of milliwatts to a [...]

Google is looking for the best young scientists from around the world to submit interesting, creative projects that are relevant to the world today. So if you have time to make it some good and  interesting project, you can sign here on this link  http://www.google.com/sciencefair.  

Today we make a new project Fastest Finger with microcontroller PIC16F628 from this link. This simple circuit has five buttons and five LEDs. Four keys are linked with players, the fifth provides manual reset. After switching on or after reset (reset, manual or automatic), all the LED off and the system is ready. One of [...]

This is my place where I spend more time in the day,here are some pictures of Tehnik Service workshop.    

If you’ve ever been designing a circuit and had to experiment with different values of caps and resistors, you probably didn’t like it much. It can be a hassle to switch out components over and over, trying to find the right combination to suit your needs.  With RC filter circuits, it can be quite difficult [...]
