View Full Version : DIY IR Blaster?

Hi,

Does anyone know how to build an IR blaster to plug into the SB2? I'm thinking it can't be anything more complex than a couple of infra-red LEDs, perhaps a resistor or two, piece of wire and a plug.

A schematic would be greatly appreciated.

Why I ask is... am wanting to use the SB2 to control my other equipment. Thinking that one could arrange various LEDs from such a blaster, taped next to the receivers on your components. Your SB2 remote because universal.

I also read that any IR signals the SB2 picks up are sent direct to slimserver. Does this mean I can learn IR signals somehow?

Cheers,

Rob

Over in the developers forum they are tesing this very thing.

Thanks Paul, but that thread only seems to concern itself with software. More than happy to try it out if I could find out the connections for an IR LED. Followed the link in the thread but there's nothing there either.

Messing about a bit I found this page: http://www.lirc.org/transmitters.html

Looks promising, but the SB2's headphone socket is 3 pin, which part of the TRS (tip, ring, sleave) is + and which - in the IR configuration?

Also, in the link I quote there's a diagram showing a 500ohm resistor in parallel with 100-220nF capacitor, anyone know if these values are correct for the SB2?

Finally, I'd like to build a kindof 'octopus' with a number of IR LEDs to place over various components, anyone know if the resistor/capacitor combo would be needed in that case? I'm guessing one could just place a number of LEDs in parallel so long as the resistor you place in series limits current sufficiently.

As you might tell, I need a little help here <:o)
