Hmm, just thought of something else with this circuit
As the signal will me modulated @ 38 KHz with a 50% duty cycle, shouldn't I drive the IR LED (max current of 50mA) at 100mA to achieve the best results because of the 50% duty cycle?
Maybe 100mA is a bit much, but surely you can safely drive them faster than their rated continues current when a duty cycle is involved?
