Update.... I constructed another using 3 ir lights from ebay, a resistor (I know) powered via usb wall adapter... OMG... I can see why you would go that extra step now... if I thought my tracking was good before.. I can only describe it as absolutely flawless now. So smooth, so responsive.. so awesome.. Thank you guys for opening my eyes.. I still maintain that as a cheap to build test bed my AAA setup DOES work. I have now ordered the proper ir leds and resistor and am looking forward to building it.
