The next level of illusion.

Sparkfun did a very cool project, using a robot and video projection to make a very awesome effect. The robot equipped Infrared LEDs moving around, while the IR camera is keep tracking the robot position and project the patterns in front of it.

Cheap wireless communcation with Infrared.

JSR,self-taught artist, made a cheap wireless communication circuit for his music project using adruino, he made a simple circuit to convert the normal UART port to infrared signals. A wireless serial port is born! The circuit and codes are simple, please check out jacob's website here.


For the transmitter, looks like:

Very simple and clean!

Video demonstration:

IR object tracking.

Using Infrared LED and receiver are the cheapest way to make an object detection sesnor, but you may require a lots of hard works. Luckily, Oddbot from "Let's make robots" worked very hard and give us a very good tutorial on IR object tracking. Source codes and circuit diagrams are included. Thanks OddBot.
