that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
HSM-20G is one of the most common humidity and Temperature sensor. This sensor is fully analog type. The outputs are analog voltages rather than any digital signal.
The datasheet indicates that the output pins need some extra devices with it. here is the connection diagram:
From the...
In this blog post i will share my Graphical Lcd libraries with you which are written for xc8 compiler in MPLAB-X development environment.
The libraries functions are inspired from mikroC functions and i tried to keep most of the functions similar to the one available in mikroC compiler.

its a simple frequency counter using the famous atmega 8 of the avr II family micro controllers. it uses counter 2 module of the IC and counts for a period of time. then the value is displayed on a LCD module. its kind of a very vague freq meter, but hey its a start!

PCB Reverse Engineering, also known as PCB CLONE or PCB Copy, is using clone technology onto the PCB which was designed and manufactured by others, it is to use PCB related software to copy someone else’s circuit board and then manufacture the circuit board by yourself. This is the tradditional...
Flexible circuits offer some unique challenges to the assembly process. The assembly materials and processes for populating and interconnecting components to a flexible circuit range are essentially identical to those used for standard rigid or rigid flex pcb, but there are some twists required...
compressing of files is what we all do to reduce the size of the file and to free spaces in our systems but is it worth the time spent for compressing files ?
no.............
why so?
most of our file compressors use lossy algorithm for compressing the files which result in the loss in...
recent study shows that most of the conventional devices have poor efficiency in the order of 30-70%
this has led to the loss of large amount of power in various forms
but recent discoveries in the ever growing field of electronics promise us that the efficiency gap can be nearly equated...

Hi,
I am introducing my new video player made using an atmega32 microcontroller and nokia color LCD. I got a 65K color LCD from an old nokia 6030 mobile...
You may have seen the great Oscar winner movie “The secret in their eyes” (If you have not, I advise you to do). However, this is not related to the topic of this blog :roll:. The secret is in the code is not a movie. It is a real situation occurs in almost every team work capacity. It is a...
What exactly is impulse response?
Mathematically speaking an impulse response is the response of a system to an input which is a dirac function (i.e. infinty at t=0 and zero everywhere else). But physically speaking what does this exactly mean? Impulse response of a system is very...
There is an ever-increasing demand for wireless broadband applications. This includes wireless HD video streaming, wireless backhaul links, broadband internet access and mass files transfer applications. All of this emphasizes the need for low cost and efficient millimeter-wave (mmWave) systems...
Hello!
I'm an electronics newbie and recently came across an oscillating opamp. I didn't even know that opamps had that problem. Through these forums and numerous online readings, I finally understood what an oscillating opamp is. I found a few others looking for answers to the same question...

Generally people use ISP (In System Programming) when it comes to micro controllers with flash memory.
One of the basic software for such purpose is FLASH MAGIC .
But every single person who has ever used flash magic knows it never works the very first time and the frustration goes on...

HOW TO BUILD "B Battery" basics on "B battery" eliminators and run vintage tube gear
There are many ways to get high voltage for projects or vintage radios/amps and tube gear. Quick searches
usually lead to great but semi-complex and expensive to build circuits for this purpose. To...

Ansys HFSS normally uses the scattering parameters convergence as a termination condition. Although, this does not necessarily mean that the solution converged everywhere, it is a fast and efficient criterion.
Few days ago, I was running the built in optimizer in HFSS searching for the...

In this blog entry I will show you how to use a 74HC595 to expand I/O pins using only 3 I/O pins of a microcontroller. The program is tested on a 16F876A at 20MHz.
The associated program shows how to transfer a byte data serially to the 74HC595 and then sets the output accordingly...
I read a small portion on Maxwell's equations in the second part of this book and I say that I have never read anything more interesting than this. It's really awesome by the way. The author is a well known personality. He is the Nobel Prize Winner Richard Feynman, who specialized in quantum...
Most microwave hardware is specified to run in a fifty ohm system. Why was this standard chosen?
50 ohms is a great compromise between power handling and low loss, for air-dielectric coax.
The arithmetic mean between 30 ohms (best power handling) and 77 ohms (lowest loss) is 53.5, the...
1.) seperate the power grounds, signal grounds, analog grounds, digital grounds, control grounds
2.) Keep inputs and outputs seperated and isolate to prevent oscillations
3.) Oscillation can happen from the inverting input and non-ineverting input of op-amps, coupling between parallel signal...
As is well known, solderability is very important for the printed circuit boards, we must do solderability test of each batch PCB we made. In this way we can inspect the weldability of the PCB before we go ahead the assembly process, much helpful for SMT.
Today we are going to discuss the...
Dear All
Hi
I came back again , with some good things !
And if you see i don't write all things at one , blog , the reason is that i want you think about things that i write carefully .
Before that , let me appreciate from "LvW" and "FvM " and "syncopator " , because of their friendly helps...
PRACTICAL CONSIDERATIONS
All this while, we’ve talked about the software side of things when dealing with the ADC. Now, it’s time to talk about the hardware side of things.
We’ve considered many situations in the discussions above. But not all of them can be used in your circuits.
