The latest 27 Inch PC with Windows 8 Touchscreen display

Personal Computers have been changed since their birth in terms of look, speed, configuration, storage and in size. The big personal computer makers have launched the beautiful and big screen Windows 8 OS based touch screen personal computer. The two big screen PC - Dell XPS One 27 and Lenovo IdeaCenter Horizon 27 are out for the gadgets lover to try new featured PCs.

- Dell XPS One 27: It is a 27-inch QHD touch panel HD display Windows 8 PC powered with Intel Core i7-3770s Quad-Core 3.1 GHz CPU along with 8 GB DDR3 RAM (1600MHz), 2 TB (Terabyte) SATA Hard Drive. It is featured with 2560 x 1440 resolution at 16.7 million colors, and NVIDIA GeForce GT 640M 2GB GDDR5, and 10/100/1000 Gigabit LAN, Bluetooth.
If we see the reviews, it has got a beautiful high resolution capacitive touch screen which gives a good user experience with powerful hardware. It has been integrated with Waves MaxxAudio 4, 6 USB 3.0 ports and allows you to connect it with TV, speakers and more. The bundled wireless keyboard and mouse were also very comfortable and easy to use, as all the Chiclet-style keys had plenty of bounce and tactile feedback, and the mouse is just the right size for our hands. It is available at $1577 at Amazon.com with 13% discount.


- Lenovo IdeaCenter Horizon 27: It is also All-in-One desktop available in two different processor Intel core i7 and Intel core i5 at two different market price. It has been considered a fun family PC with lots of casual gaming potential. It includes several gaming accessories and has a custom user interface, Aura.

It comes with Full HD, backlit display with 90-degree adjustable viewing angle in AIO mode with Standard NVIDIA discrete graphics and 720p HD webcam, Dual digital-array microphones, Integrated stereo speakers, Lenovo Cloud Storage, 2x USB 3.0 SuperSpeed, HDMI-in, 6-in-1 card reader, Wireless keyboard and mouse.
If we look at the review, it is a good PC that allows you to play pre-installed games with your family, but it is heavy and short of battery life lasts only in 2 hours. It is slightly costlier than Dell All-in-One desktop, costs around $1900 with Intel Core i7 processor.

Buzzer interface with 8051 microcontroller

Buzzer  is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor.  Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long i...

Comparison Chart Between 8051, 8052, 8031and 8751

8051 is a popular 8-bit microcontroller and has been used in many applications since Intel introduced it. Many 8051 architecture are produced by Triscend, Intel, Atmel, Philips, Infineon (Siemens), ISSI, and Max Corp. Today, 8051 microcontrollers may not be popular but, the 8051 architecture is still popular and employed in thousands of embedded applications. This 8-bit architecture has been different segments such as 8052, 8051, 8751 and 8031 . 8052 is the super-set of 8051 and 8031 is the memory-less microcontroller hence, it has interfaced with external ROM. Whereas, 8751 chip has only 4Kbytes of on chip UV-EPROM. Everyone knows about the general 40-pin microcontroller i.e. 8051 introduced by Intel in 1980s and consists of serial communication pins, Timer, Interrupts, RAM, ROM. It has 4 ports and each port has 8 pins, total 32 pins and other 8 pins for other purposes. 8052 is the super-set of 8051 that consists of 8K bytes of internal RAM (4K in 8051), 256 by...

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop   program function in which Delay() funct...
