Hey guys, quick question before I proceed with this plan. I need to feed two IR signals coming from two distribution blocks into a single IR blaster. My plan is to stick a 1n914 diode on each positive lead and bridge them into the IR blaster, all sharing a common ground. Is it as straightforward as that?

I've seen very similar circuits to what you are proposing - for some reason there's quite a bit of interest in the Linux community to control devices from a serial port using IR - seems to be a proven way to go.

Or you can buy one ready-made from Xantech for exactly this purpose - the 282TPD "Twin Plug" designer emitter...

I've got several of these myself...

There's "labor of love", and then there's just "labor"... wink.gif

Honestly, when it comes to IR, I avoid anything DIY I can, because diagnosing problems with invisible stuff, is, well, frustrating...

I'd go for that, but I need a blaster. I haven't come across a blaster with two plugs and diodes.

Any excuse to turn on the soldering station is a good one. There nothing a cell phone camera and a multimeter can't solve (save for most, if not all, non-IR related things)!

If you truly need a blaster (to cover a large area / multiple devices), why not just put two next to each other? They're not very big, it's not like folks are going to notice them...

That's actually my current setup. I just want to have one strictly for aesthetics and nothing more than that to be honest. I bought a Niles IR blaster because it was the nicest looking, and the Global Cache blaster looks out of place next to it (especially because it's blue on the all black). I figured a few cents in diodes could get rid of an eye sore. (And this is coming from originally having emitters stuck on each device.)

Thanks for the quick response Dave! For some reason I thought I had already replied to you smile.gif.
