Dual-Channel Mobile Surface Electromyograph Using Atmega644

Introduction For our final project, we built a surface electromyograph to collect and analyze data on muscle activity, which supports two channels, implements wireless transmission, and can be worn as mobile unit. Surface electromyography (EMG) is a noninvasive technique to record the activation signals of muscles when they are mechanically active. This signal is very […]

Flickr images on a Nokia LCD using ATmega48

LCDs are often used in microcontroller projects. Most used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. Some time ago I ordered a Nokia 6100 LCD including breakout

DIY mobile phone – Create your own mobile phone

This DIY cell phone created at MIT manages to have something for just about every major contemporary subculture or hipster subset I can think of. Nerds and tinkerers? Check. Wooden case for the steampunk set? Check. Huge antenna for the retro, skinny-jeans-wearing set? Check. Big buttons for the fat-thumbed and Luddite crowd? Check. Rugged design

SMS control 4 way remote control relays using ATtiny2313 microcontroller

Introduction With this circuit we can control up to 8 devices (4 devices in our example project), by sending a specific SMS message with any mobile phone. It’s very useful inĀ the case that, at the place we have the devices, we have not a wired (fixed) telephone line. If you have an oldĀ ericsson mobile phone
