Flickr user "reconscious" doesn't consider his Roomba as just a common janitorial buddy. No, inside that little robotic case was the spirit of an artist...an artist whose potential was unleashed with a little DIY hardware additions using 2 blue LEDs, a 220 ohm resistor, alligator clips, and a 9 volt battery to unleash the vac's inner Jackson Pollock...
"I swapped the LEDs around so that the forward velocity reading was feeding the red LED, and was almost always on. The blue and white LEDs lit up whenever the Roomba slowed down or its motion jerked. I either have a rough unevern carpet, or the Roomba's little motor was having a hard time. I suspect the latter since it was running off of a 15 minute charge."
Interesting both as a photographic image (shot with a Canon EOS Digital Rebel XTi) and also as a reference to note how effective the Roomba vacuum is at covering a space during a 10-30 minute cleaning outing. You can see here that the Roomba covers about 95% of the room in about 30 minutes. Pretty good considering you never have to lift a finger.
