The dumbest design flaw I've seen in a while.

You haven't listened to music radio stations recently. Most "popular" music is designed and engineered to have a constant loudness.

a bigger cap should make it a minute

Probably a timing given by a micro processor. Then the only way to defeat it is to inject a periodical signal that is above the audio range but still recognizeable by the detector. Got to watch out that it doesn't annoy animals though as they can often hear much higher frequencies than we do.

This was an issue many years ago - 1973[1] or thereabouts - at BBC radio before 24 hour broadcasting. The transmitters were fitted with a circuit which would switch them off if there was more than a minute[1] of silence.

BBC Radio 3 was and is a classical music station[2]. A minute[1] of 'aesthetic pause' wasn't uncommon.

[1] Whatever. Something like that. Too long ago. [2] Probably the best in the world.

I found a bookshelf amp with speakers that a neighbor was giving away for free. The built-in tape player makes an annoying noise on startup but it makes an amazing amp for the computer.

Maybe listen to music without quiet spots? :)

A simple picaxe monitoring the input and putting out a low level burst of noise at 9 seconds would work - easy to knock up too. Could also be done with some 555's (missing pulse detector) plus glue

I sorta expect that this isn't a problem for the product's intended demographic: the very large number of young folks who listen to modern pop music, which simply doesn't *have* any 10-second quiet periods in it. It's all been loudencompressified to death, has a total dynamic range of maybe 3 dB on a really good day, and is either THERE or ( )

Thanks for the warning, though - I won't buy such a monstrosity myself. I have this atavistic preference for dynamic contrasts and subtlety in the music I play...

I'd like to find a decent remote bluetooth speaker that doesn't use a battery and doesn't cost an arm and a leg. I had some old Sony speakers that I got off Freecycle and got an $18 bluetooth module for music in a car. I lucked out and the internal PSU put out about 30 volts which was in the range for the module. I embedded it and it worked great. I had the speaker close by so I could tweak the volume knob (my preference over on PC controls) but didn't need another wire plugged into my laptop which moves around.

I worked pretty well for about a year until it stopped pairing with my PC. I'm not certain if it is a hardware problem or a software problem on the PC. I need to see if my phone can see it.

The producer was suppoosed to 'book out' any extended silences so that the transmitter engineers were warned in advance, the automatic circuit could the be over-ridden.

The transmitters didn't switch off immediately, they switched to an incoming feed via an alternative route or an off-air receiver tuned to another station in the chain.

Decided winter is still too far away to live with this idiotic flaw.

've-seen-in-a-while/msg1023011/#msg1023011 Fixed.

But that's too pedestrian and not sporty enough :-)

A real manly solution would be a transistor stage in the shape of a regenerative receiver, except that the stage is tuned to some really high audio frequency instead of RF and is squegging into brief oscillation bursts.

Yes. That is refered to as CCAA. Continuous Cacaphonous Auditory Assault. Responsible for much of the brain numbness plagueing the youth today.

Yep - in my older age I've stopped being sporty - ever seen a 100kg man run without a shirt (don't try to visualize - it's not good). My concern with near/low ultrasonics were possible filters, a/d acquisition times and driving the nearest dog/teenager mad. Hum..., put that way.... there could be advantages.

Don't stop. Becoming sedentary is a fast and at some point irreversible path into a nursing home. Now that I am gradually approaching retirement age I have upped my game when it comes to mileage on the mountain bike and road bike. Once I can ratchet down to 3days/week or less I'll start doing 80-100 milers, all day rides.

I regularly see such a guy on bike trips east. It is not a pretty sight.

Probably only a tiny amplitude is needed here and the speaker will have very poor efficiency so not much gets through the chain. Also, one might be able to simply use a continuously running oscillator which has the least chance of disturbance.

That's not bad. Did you find out how the micro was detecting sound?

VCR clocks.

Not becoming sedentary is not a choice I can make. I do what I can but it is a long way from bench pressing more than my body weight and squatting almost double - plus fun with karate. I loved it. But I mustn't dwell or the 'black dog' will come and bite me.

Now that I am gradually approaching retirement

It's strangely hypnotic. Yes, it's like a lava lamp. Mulder and Scully (Simpsons quote)

Just musing - a random noise source (pink or brown) might work well. If the environment is loud enough it might even pass totally unnoticed.

A handheld digital meter with 'power saving' issues an audible warning beep when it has decided to save power due to inactivity, although it is serving it's function with a non-zero or non/overange display. Nothing you do subsequently will prevent the shut-off, except recycling the power before it happens.

RL

Sure, if some other health issue comes in that can place a major damper on activity.

It's plain ugly.

It depends on how they structured the detector. Most likely it is doing its job in the digital domain. It should be happy with a constant or almost constant noise because many people listen to the soothing sounds of ocean waves. Gentle ones, not the daredevil surfboarder type of wave.
