Summary

I have two of those clean robots from iRobot ... and just for fun i dicided to build my own virtual-wall clone .. well they are quite cheap on ebay so there's no real reason for that except hobby ;-)

Instructions

Print it and attach your electronics to it.

a sample circuit is attached ... it can produce any signal you like ...
also some sample code .. producing Roomba signals ...
the code is from "http://adrianlombard.wordpress.com/2009/01/18/arduino-irobot-infrared-communication/" .. i just changed a few things ...

please note: if you use a attiny85 .. you have to "burn the Bootloader" in the arduino-ide to get it running at 8 mhz ... by default it is running at 1 mhz ... well a arduino is running at 16mhz so you have to divide all timings by 2 ... thats the reason why:
const int PULSE_WIDTH = 5; // time between pulses, in microseconds
is 5µs instead of 10µs ...

so everything is said .. except .. the MC7805CT supports input-voltages from 5v to 18v ... i use a 9v-block battery to powerup the virtual-wall.

!!! UPDATE !!! -= Please not a build another one .. and that wasn't running ... i triggered out that the 330 Ohm resistor is to low for the IR-Diode and the Current will block the ATTiny ... just us a higher Resistor ... at the moment i use 2*330R .. =- !!! UPDATE !!!
