MicroZed is a Powerful and Low-Cost ARM + FPGA Linux Development Board

MicroZed is a low-cost development board from Avnet, the makers of the $475 ZedBoard and the entry level MiniZed development boards. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation or combined with a carrier card as an embeddable system-on-module (SOM). The MicroZed processing system is based on the Xilinx Zynq®-7000 All Programmable SoC. The Zynq® ...

Transistors- The 70-year-old invention that changed the world

Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum tubes, which could be several inches long, consumed massive amoun ...

ACCESSIBILITY APPS GET HELP FROM BLUETOOTH BUTTONS

Ever hear of Microsoft Soundscape? We hadn’t, either. But apparently it and similar apps like Blindsquare provide people with vision problems context about their surroundings. The app is made to run in the background of the user’s mobile device and respond to media controls, but if you are navigating around with a cane, getting to media controls on a phone or even a headset might not be very convenient. ...

Butterfly IQ – Ultrasound Anywhere, Anytime

Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe), then the probe collects the sounds that bounce back, and a computer uses th ...

Arduino Sunflower – an Electronic Sundancer

Maker is always sensitive to the new and funny things. One day, I watched a video, in which the sunflower moves along with the sun. I had a sudden insight then. Why can't I make a electronic device inmitating this biomechanism. In the following days, I began to carry out my solar tracker project. I selected the crowtail as the microcontroller board, and picked up the componets and accessories in our warehou ...

Harvesting Sound Energy From Passing Cars

There is energy everywhere around us and in many different forms. Many devices have been developed to harvest light, wind, waves, and more. One unusual place of energy harvesting is from passing cars. As cars pass by some of their energy is released in form of sound. Even though the overall energy maybe small it can be harvested. In this Instructable I will show how to apply the solution of Euler–Bernoulli ...
