In this project we are going to build a piece of entertainment using Arduino. We all have that habit of tapping Table or Pen for creating any random music. Of course it might not be considered as a good mannerism, but we all enjoy doing it at least once. Hence I thought of taking it […]

The other day Linda from Purchasing came to me with a problem: Lou from Operations needed to source a replacement for a shorted diode on a switching power supply. The darned thing was marked with a strange part number that no amount of Googling could decipher. There was a recognizable logo marking, but that manufacturer

MIT researchers have developed a new type of radio frequency identification (RFID) chip that is extremely difficult to hack. If such chips were widely adopted, it could mean that an identity thief couldn’t steal your credit card number or key card information by sitting next to you at a café, and high-tech burglars couldn’t swipe
Hack-proof RFID chips claimed by MIT Continue Reading
Oscilloscopes and Signal Generators are two essential electronics devices to create and test electronic circuits. Unfortunately, these devices are very expensives for students starting electronics, or makers who want use electronic circuits in their creations just once… The idea of my project is to rethink your smartphone as a portable, powerful and secured platform, able

You don’t need to travel far in the Dutch countryside before you come across a traditional windmill. Now a consortium of Rotterdam-based companies are planning to build a massive wind-powered generator structure in Rotterdam harbor that will generate energy without using rotating blades. The innovative ‘Windwheel’ will work on the EWICON (Electrostatic WInd energy CONverter)

A frequency generator is a very handy device in electronic design, development, testing and trouble shooting. It is such a kind of device which can generate the required frequencies which can be then applied directly to the target device for testing it. There are frequency generators which can generate the required waveform like sine wave,

Motivation I was building some Lo-Fi CMOS synthies, just like the ones you see here: http://hackaday.com/2015/02/04/logic-noise-sweet-sweet-oscillator-sounds/ or here: http://www.nicolascollins.com/hackingtutorial11.htm Soon after I played around with some simple sequencers and multiplexers to generate more complex sound patterns. I thought it would be cool to have a device to gate oscillators or switch multiplexers with a random

Build an Arduino-powered version of the “Four Letter Word Generator” (FLW). This version generates “words” on the fly – it does not use a list. The “original” version from the 1970’s used B7971 nixie alphanumeric tubes. These tubes are getting hard to find and they’re certainly expensive. They also require interfacing with high voltage and

In this episode Shahriar compares the performance and features of the Siglent SDG5162 and Rigol DG4162 Arbitrary Waveform Generators. Siglent has recently opened a new North America office which would certainly help them bring their instruments to the US more quickly and provide better local customer and sale support. The Siglent SDG5000 teardown is presented.
Introduction An excerpt from OmniGlot.com about the origin of Morse Code: Morse Code was invented by Samuel F. B. Morse (1791-1872), a painter and founder of the National Academy of Design. He conceived the basic idea of an electromagnetic telegraph in 1832, and produced the first working telegraph set in 1836. This made transmission possible
