Wrap Beats is an instrument that lets you string together notes in order to create different melodies and visual patterns. I constructed it using the Capacitive sensing library for Arduino and combining that with the music abilities of processing to create a dynamic instrument that can change sounds as you play it. The circular design […]

Power management in portable devices is one of the toughest challenges faced by electronic engineers. The consumer demands instant response from their device, lots of functionality, and a large, bright and colorful touchscreen. Moreover, many of these portable devices now incorporate wireless connectivity that places further demand on the cell. And yet, the user expects […]

I got my start in microcontrollers with the Arduino, as many of us outside of electrical engineering did. (And still do!) The ease of programming that little board makes it a great gateway… and like any gateway, sometimes you go through. Most of my projects now don’t use Arduinos directly. For simple microcontroller applications, it’s […]

Shared circuits is a place where you can showcase your circuits projects to the world. Be it a simple rat’s nest doodle to a complex multi layered PCB with all the bells and whistles. If you want to show of your design, then this is the place to show it off. And it’s free. Just […]

The RFI-DJ is a USB device for playing MP3 files from your computer. You have a set of RFID cards, each one with a song name written on it. You choose a card and place it on the RFI-DJ, and your computer will play that song. Its magic! Actually, it’s not magic. It uses an […]

My students need to learn LabVIEW —I know, it’s proprietary software, and expensive, but until a viable open-source equivalent comes along we’re stuck with it— and one of the exercises I have them do is to make a program to analyze radioactive decay. This gives them experience in using counters, plotting data in real time, […]

Researchers at Scandinavian research organization SINTEF have made progress in developing components that dissolve in water. Printed on a silicon wafer, the components contain extremely thin circuits — only a few nanometers thick — that are designed to transfer energy. They are made of a combination of magnesium, silicon, or silicon with a magnesium additive; […]

Hi! In this tutorial you will learn to make a mood lamp with Arduino. I know that you may have seen a lot of mood lamp projects with Arduino, but I wasn’t very satisfied with them because they all change the color very abruptly. So, I decided to make a smooth mood lamp and I […]

Software simulator for Electronic Assembly display EA DOG series will bring you a clear image about possibilities of this favorite series. Usually, when we start working with some monochromatic display with a color backlight, we have to imagine which combination of display/ backlight would suit us the best. It isn´t hard but for sure even […]
