Where on/off ?

You said you didn't find the on/off switch. That would suggest that there isn't one.

My guess is that the light is turned off simply by orienting it 90 degrees, and turned on by placing it upright.  (easy enough with a rolling ball switch). midway between the two, there might be enough resistance to go into "low battery mode", which is normally the problem when such devices beep and flash to attract attention.

mtripoli3 you are an absolute genius.  That's a brilliant idea and the perfect way to repurpose cheap technology.

What about, shake the light for service???

Maybe it was intended to get the attention of the serving staff. A button might be too hard to find or see. So they simplifed the activation. Why beeping and a flashing light. We can't base it on our culture. It might be perfectly acceptable elsewhere. It changes the whole perspective, the designer is a genius...

A better candle flicker
mtripoli3   6/20/2013 10:10:09 AM
Years ago, actually before the first of these "candles" rolled out, I was working on an "artificial candle" for a project. The company had used a few different consultants and they weren't satisfied with the "candles" they had seen. Mine, they said, looked so "real" it was eery. They wanted to know what kind of "algorithm" I had used to produce the flickering of the flame. I told them, buy my design and you'll know. They did and I fessed up; I had used some "old" sound chips from another project as the source for flame flicker. Simply attached the led (a yellow one) to the output of the sound chip. These chips use PWM and worked perfectly. If someone had put a speaker on the "flame" they would have heard some version of "Happy Birthday" IIRC. When the device went into production we bought up all kinds of old and overstock sound chips to use as drivers, for 10th's of a cent each.

Yes, you are so right they generally don't understand what they are copying, so will faithfully reproduce every nuance. In the case of the jacket, you need to look no further than people being silly enough to buy pre-worn-out jeans with holes etc. why wouldn't a cigarette burn make sense under those circumstances?

I seriously have to agree with you, that would make perfect sense.

Another would be product differentiation. I come across 100's of designs that have some stupid feature in a misguided attempt to stand out.

Another explanation is someone wanted to to see how long he could keep a bunch of people musing over the waste of time or otherwise of that feature?

We could go on forever.

Maybe someone will decide that so much brain strain is bad for our health and emulate the 50 page manual I once got (in CD form) for an MS mouse that explained the hazzards of RSI (Repetitive Strain Injury) when using a mouse for extended periods. The driver was some 100k and the manual was in the order of 3MB


I'm still betting on your suggestion.

ALL explanations are fine, BUT all miss the point.....

I can tell y'all WHY this was incorporated.  The programmer read in the data sheet for the controller that there were EXACTLY so many electrons available, and since he/she knew that this limit was nowhere being neared w/ all the features already programmed, they set about to add this "tilt" feature also.  And, that's how it happened.......

Alarming candle noise

Perhaps it's used as an alarm to thwart theft.

I think they kept the light for just a fun or to make some mimic with the customers.

It's maddening sometimes, isn't it, when there are such idiotic design features of a product (or lack of, in the case of your chair, Ann!). Now that I write more about design I start to look at products in a different way and start to see where things could have been done differently. I can't think of any examples of any silly design features at the moment, but can anyone else? Maybe it will jog my memory.
