The crew from AnalysIR reports they have written up an article on constant current circuit for Infrared LEDs – similar to that in the USB IR Toy. They compare the various methods of driving IR LEDs, including a series resistor and a circuit driven by an NPN transistor, and how to design your circuit for maximum brightness.
