eDavid the robot painter excels in numerous styles

The line between art and technology isn't just being blurred, it's being erased altogether. Painting and sketching from photographs and life, for example, is a technique that is now being mastered by robots. The latest, called eDavid, combines a camera, computer vision software, and a standard welding robot arm to skillfully recreate (in a variety of styles no less) any image…

ATmega328 Overclock (30MHz)

Hello everyone,

This is more fun oriented project than something useful (or not) since ATmega328 was not designed for clock frequency above 20MHz (see datasheet). So, 30MHz is push it far from the limit. :)

Besides, I…

WebServer for Arduino without EthernetShield (with PC/Apache/PHP)

Hey guys!

A lot of people ask how to connect Arduino to internet, so it can interact getting data from the internet and actuating physically. Let's say, turning a light on/off, open/close a garage door, turning the coffee maker on. :)

To do this, we could use an EthernetShield, giving the "power" to Arduino access the internet. Or we can leave this power to a PC, which already have it, and then the PC, through the USB, will send the info to the…
