New technique for generating electricity from mechanical vibrations

Electronics News Updates / By Ibrar Ayyub

Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to “harvest” the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes, […]

Morse Code Decoder

Electronics News Updates / By Ibrar Ayyub

Morse code is used in telecommunication; it is a method of transmitting and receiving coded information. Each character (letter or numeral) is coded/represented by a unique sequence of dots and dashes. Compared to voice, Morse code is less sensitive to poor signal conditions, yet still comprehensible to humans without a decoding device, therefore, a useful

MinieC I2C eC interface

Electronics News Updates / By Ibrar Ayyub

While working with Peter from ManyLabs/WireGarden, we wanted to begin to create a system of open source water quality sensors that can be cheaply deployed in schools, remote research, maker projects, basically anywhere there is a need! This project is the result of the knowledge gained from the pH line of interfaces combined with research and

Breadboarding the 68K

Electronics News Updates / By Ibrar Ayyub

My 68K breadboard computer is alive! It’s always a thrill when a pile of random chips does something recognizably computer-ish for the first time. Blinking some LEDs in sequence is great; running BASIC is super extra great. I’m excited. This simple breadboard machine is a prototype of the 68000 single board computer I plan to

Low-Frequency Converter

Electronics News Updates / By Ibrar Ayyub

Among the signals below 550 kHz are maritime mobile, distress, radio beacons, aircraft weather, European Longwave-AM broadcast, and point-to-point communications. The low-frequency converter converts the 10 to 500 kHz LW range to a 1010 to 1550 kHz MW range, by adding 1000 kHz to all received signals. Radio calibration is unnecessary because signals are received

Battery Fuel Gauge with Zero Parts and Zero Pins on AVR

Electronics News Updates / By Ibrar Ayyub

It can be nice to know how much battery power you have. It becomes critically important with LiPo batteries since you can permanently damage them by running the voltage down too low. Typically battery voltage detection requires adding a circuit with extra parts and their associated power requirements. Wouldn’t it be great to be able to do this using

Using the Cirrus Logic CS5464 for AC Current Measurement

Electronics News Updates / By Ibrar Ayyub

Continuing the series on examining devices to measure AC current, this time we’ll try out the CS5464 from Cirrus Logic. I initially built it up on a breadboard, but I’ll skip writing up this test and instead build up a prototype and run AC line power through it. This is a Three-channel, Single-phase Power/Energy
