Hmmmm? Does "religious nutbag" status negate truth?

Yep.

For a remote control? You'd need an adaptive loop to make sure it didn't talk to itself (i.e. to reproduce the function of a telephone hybrid), or use a laser diode for the TX and notch out the laser wavelength at the detector (notch filters aren't that common unfortunately, but you could use a sharp-cutoff longpass). Those are both good for one hop.

Don't they transmit fixed-width pulses? If so, detect the incoming leading edge and fire a huge blast of reinforcement, like a photoflash repeater. That might network over some number of scattered units.

I ordered some diodes and emitters to play with.

I'm thinking of simply hard wiring, since equipment location _is_ around 60' from where I'd like to control it.

However there is a light path back if things bounced around enough.

Wonder if one couldn't delay the output, blank input, then "spew".

Although I suspect that really won't be necessary.

Seems like that's one of your eternal honey-do projects by now. Can't you just place a li'l transmitter in the remote on some ISM frequency that's unused in your area, then place a receiver near the location where the audio or video gear is and let that blink a IR LED? Doesn't have to by right there, could be behind a flower pot as long as the IR LED has a somewhat clear shot. The highest rep rate I've seen in a remote here was somewhere around 45kHz, not a whole lot.

That would probably work well. (I know zilch about remote control outputs except that they're pretty slow and work at about 900 nm...I don't watch TV or videos.)

20-50kHz base modulation, burst transmissions of the data bits. You can easily see it by hooking a photodiode to a digital scope in single-shot trigger mode, then hold the remote at it and press a button. I trust that you'll have one or two photodiodes at hand :-))

Hint: Photodiodes scrapped out of TVs and VCRs are often active circuits, with narrow filters in there. Need supplies and may not match the remote control under test.

I bought a commercial IR->RF transmitter and an RF->IR receiver. It was crap and erratic if the receiver was located anywhere near the TV.

Likewise with the LinkSys wireless WAP54G... which I why I hardwired the CAT-5 connection to my Roku Soundbridge.

So I'm going to wire this repeater by pulling telephone cable down the same space where the rear speakers are located... then IR straight across the room to the cable converter.

What frequency does it run at? Best would be one of the VHF bands.

The 2.45GHz WLAN gets corrupted by the TV? Did that TV ever pass EMC?

That's the real way of doing it.

Around 32 kHz rings a bell. The 'flash repeater' idea should work considering that.

Jim was teasing me about using laser noise cancellers for everything.

formatting link
Of course, they do get you 50-70 dB improvement in most laser-based measurements for almost zero parts investment, but nevermind....

I'm currently at work on a well-upholstered version of the noise canceller, intended to require less thought on the part of the user.

(Not to diss the user--he has complexity of his own to worry about without having to care about mine.)
