Tetris in Real Life

All of you must have played a very famous game know as Tetris. This review is about ‘myTetris’ which is a giant (~6ft tall) physical version of Tetris developed by National Instruments. It features a grid of 10×20 RGb leds along with myRio. For those who don’t know myRio is an embedded hardware device designed specifically to help students design real, complex engineering systems more quickly and affordably than ever before. It has a dual-core ARM® Cortex™-A9 real-time processing and Xilinx FPGA customizable I/O all in a single board. The game can be played using any browser including those of mobile and tablets. The user taps the buttons on the web-page or use the arrow keys on the keyboard to move the tetrominoes.  The web-page on your bowser also update … Continue reading

NES On-A-Chip – The Embedded System in VHDL

First of all, did you know what VHDL is? For your information, VHDL is commonly known as a design-entry language for field-programmable gate arrays and application-specific integrated circuits in electronic design automation of digital circuits. VHDL is derived from VHSIC hardware description language, where VHSIC stands for “Very-high-speed-integrated circuit”. Based on the information, VHDL was originally developed at the US Department of Defense. The main purpose of the mission is to document the behavior of the ASICs that supplier companies were including in equipment. This means, VHDL was developed as an alternative to huge, complex manuals, which were subject to implementation-specific details. Well, this NES On-A-Chip’s main goal is to implement an older embedded system entirely in VHDL. In this case, you might want to choose the NES, as its … Continue reading

The Simple Light Source Motion Tracking

In the past, it’s very hard for us, especially the ordinary civilians to track light source, as we didn’t have the chance to buy or build our own facilities to perform this task. However, time passes by and everything is constantly changing. Today, we’ll have the opportunity to develop our own simple yet powerful light source motion tracking system. The main objective of the project is to accurately detect motion and report the speed of moving light sources in the view of camera. Basically, you can use this light source motion tracking system for many purposes. Let’s take an example. A night vision goggle that sees certain light spectrums is able to detect enemy motion, even in the darkest places! Honestly, the project is built on an Altera DE2 development … Continue reading

The 32 Channel Logic Analyzer

You’re working in the electronic field that require you to observe and check out the digital system with precision, but you didn’t know the proper way to build it? If you’re having the difficulty, then today’s your lucky day, as we’re going to develop a 32 Channel Logic Analyzer! For those who never get in touch with logic analyzer before, it is an electronic instrument displays signals in a digital circuit. Practically, they’re used for capturing data in systems, which is having too many channels to be examined with an oscilloscope. The software that running on the logic analyzer can be used to convert the captured data into timing diagrams, protocol decodes, assembly language and much more. For your information, the logic analyzer that we’re building today is a 32 … Continue reading

The Outstanding Parallelized Knuth-Morris-Pratt Search Algorithm

Search algorithm might be sound a little bit unfamiliar to general people, as most of them didn’t know what’s the main purpose of this system for! Did you know that search algorithm is one of the important factors in computer science, where is an algorithm that takes a problem as input and returns a solution to the problem. In most of the cases, the algorithms studied by computer scientists are normally in the form of search algorithms. Basically, there’s a set of possible solutions to a problem, and is being given named as the “search space”. As a result, the algorithms use the simplest method of the searching through the search space to reduce the amount of time spent for searching! The main objective of the project is to demonstrate … Continue reading
