I've had my WF2IR for less than a year, I am using it in conjunction with Demopad and an iPad Mini. Recently my IR blaster stopped working. I made a blaster myself using some IR LED's that I had. It works great but I am wondering how many LED's port 3 set as blaster can power and if the output is current limited or do I need to add a resistor? I measured the DC voltage pretty low at .5VDC, maybe my meter wasn't quick enough though. The reason I ask is I want to make a multi direction blaster using multiple LED's so the IR signal gets blasted in many different directions, I am thinking 4 LED's or so.
