Any suggestions on a well made passive, IR distribution block that has screw terminals for IR in and then three or four 3.5mm ports for IR out? (The use case, of course, is splitting an IR output feed from a controller without having to rely on splices.)

If it's not simple, it's not sufficiently advanced. |

This is something I could use provided the current is only split up over as many outputs as are actually in use. I'd prefer the device have fewer outputs, though. [Link: xantech.com]

Doesn’t fit the bill for input, but does for outs- [Link: rticorp.com]

Thank you, that’s actually perfect. I was thinking 3.5mm IN might actually be the way to go, anyway.

Xantech 789-44 ( [Link: xantech.com]) will fit your original scope. It's passive as an IR port expander; power supply is only needed to drive IR receiver(s).

Right. 789-44 is THE CLASSIC BASIC CORRECT distribution block.
In the past I've had to come up with a smaller distribution block. I used two screw terminal blocks several 470 ohm resistors. In the 789-44, the IR buss ground goes to the minus of each LED and there's a 470 ohm resistor between each LED plus and the IR buss hot. Thus you'd need three resistors to feed a signal to three LEDs, for instance.

There's no worse feeling than that millisecond you're sure you are going to die after leaning your chair back a little too far. |
