Sorry for the ignorance. I'm trying to figure out how these parts work> 274-374 (Phono Plug) and 274-251(jack) I ordered these two parts from RadioShack and they don't appear to be correct. Maybe the part numbers have changed? The plug doesn't come apart and I see no way to use the Jack with this part.
how would i modify this circuit for, for example, being driven by an Arduino? these devices supply perhaps 40mA max current and do not contain the current-limiting resistor apparently present in the Ocelot.

I would need to know what kind of output circuit that device has. Are the output connections labeled in any way that might give a hint, such as cathode, anode? Or + , - ?

I put a small circuit together as such (under "IR-Driver transistors") and it works. Thanks for "turning me on" to the idea, and for being responsive and helpful once again.
