Allan, Thanks for the info. I have a couple of points that need clarification:
1.) You are actually phyisically modifying the 150? The wires that go to pins T1 and T2? 2.) I don't quite understand how if the PC appears to freeze when you run lmilk -2 (locks mouse), how is it possible to issue IR Transmit commands from the software? The irony of all this, is that the components for the cheapi2c are going to cost about the same as making my own IR Blaster. Oh well, I'm going to have to chalk it up to "Adventure" and "experience" -G > Allan Stirling wrote: > >> >> In addition to the (simple) circuit described, you need to add a >> 800ohm resistor between pin 25 and pin 12 to bring the voltages on the >> '150 down to 3.3v again.
