Using mobile phone as an internet radio

There are many applications where incandescent lamps are turned on and off
constantly and their life span is the same.

There were many installations using thermionic valves where very long
life was achieved by leaving them running continuously. The GPO had
discovered this and it influenced Bletchley Park with their early
computers, some did not believe they would get a reliable system but the
GPO engineers working there convinced them that it was possible.

There are frequent stories in the press of incandescent light bulbs that
have been running continuously for very long periods - tens of years.

Just like not using it does in fact.

Using anything shortens it's working life.

It would be a strange way to rate the life of a lamp - on constantly,
since this pretty well never happens.

Do you find the 'flasher' lamps on your car failing more quickly than
similar lamps which don't flash?

Not so. There aren't any obvious failure mechanisms in solid-state devices
(other than dopant migration in high-power output transistors).

Yes interesting that especially in high power RF transistors, 'tho I
believe in such cases its paralled emitter connections that start going
open circuit...

It's also true that most mechanical devices "like" moderate use. Letting
anything mechanical "sit" most of the time will probably cause it fail
sooner than if receives regular use.

It's now possible to build computers without moving parts (other than the
optical drives). My new computer has a solid-state "hard disk", and you
wouldn't believe how fast it boots up, or how fast programs start to run.

Indeed they do just got one, not in this machine but very fast indeed.
They still it seems fail though...

Of course, the lifetime of light bulbs is part of an international

I don't agree but will say no more.

Laser printers. I have given away for parts several laser printers because
they sat unused 99% of the time, and started to jam when I printed the
one or two pages a month I needed them for.

Not only did the rubber wheels dry out and lose their ability to grab paper,
they flatten where they are pressed against something.

I have a perfectly good Samsung laser printer in that condition now.

My choices are to once a week clean out a jam, and clean the feed roller;
print something everyday (a waste of paper); spend $15 for a new roller
(including postage) and an hour to install it; or wait for a sale
(every 2-3 months) and buy a newer faster, higher resolution model with a
2,000 page toner cartridge included for less than the cost of a full load toner.

I can vouch for the remark made but I can give you more details too:

I use smartphones, tablets and laptops to listen to internet radio all the
time and I've only had one device that suffered because of that. What
happened to that particular device is the WiFi quit working and it doesn't
even work after a factory reset.

But out of all the other devices I've used they haven't demonstrated any
problems at all.

Who knows why the WiFi quit? The radio could have failed simply because the
chip went bad.

HP has had problems with the radios in some of its notebooks.

Yes, I've heard that and I've even seen one person that no longer has WiFi
on their HP notebook but they claimed it was the switch itself that quit
working so I try not to use the hardware WiFi switch on an HP notebook.

Me, I've had a power plug fail on an HP ZD7000 notebook and that was common
for that particular notebook.

I've also had a DVD fail on an HP DV8000 notebook but when the second DVD
failed too I went back to the first DVD and it has been working fine since
then. I doubt if I'll ever figure that one out unless if it was a problem
with the connector.

Other than that, I've seen a lot of videos on youtube with problematic HPs
where if it isn't the WiFi that goes out it is the video. Case in point:

HP 's Worst Laptop Ever - Pavilion ZD8000 -
http://www.youtube.com/watch?v=2stqQtQePcM&hd=1

Oddly enough I skipped getting the HP ZD8000 because I went from an HP
ZD7000 to the HP DV8000 where the ZD8000 looks more like the ZD7000 than the
DV8000.

FYI the only device I had that lost the WiFi was a Pharos Traveler 137 that
I got real cheap when a place was getting rid of them so I wasn't too upset
when the WiFi quit on that.

http://www.pharosgps.com/products/proddetail.asp?prod=001_PTL137_8.00

But the video on certain Dell Laptops? Don't get me started.

I don't know of any data that supports this common idea, but I'd be
interested in reading about it if anybody's actually done the experiment
carefully. Electromigration is a smaller effect in an AC bulb, since
the leading order effect cancels.

I suspect that the notion that cycling is hard on bulbs comes from the
way that the bulb often fails at turn-on, when the thinnest hot spot
vapourizes before the rest of the filament has a chance to come up to
temperature and reduce the inrush current.

The tungsten in the lamp is run within a few hundred kelvins of its
melting point, so it's always in the fully annealed state, which ought
to mean that there are no metal fatigue mechanisms operating, just
material migration due to sublimation.

Every wonder where the 1000 hrs came from?
<http://en.wikipedia.org/wiki/Phoebus_cartel>
<http://en.wikipedia.org/wiki/Planned_obsolescence>
If you stress a 1000 hr incandescent bulb, the lifetime will be even
less.

It also applies to CFL bulbs:
<http://www.telegraph.co.uk/earth/environment/6122459/Lifespan-of-energy-saving-bulbs-reduced-by-repeated-switching.html>
The lifespan of energy-saving light bulbs can be reduced
by up to 85 per cent if they are switched off and on too often...

You'll have dropped it well before it wears out .

You'll wear out the batteries before you drop it and you'll want the new
iThingy before the batteries die. Full employment for the phone company.

BTW, a cheap PC
speaker set might be handy if you want a little more volume. And you can
probably find a decent streaming client if you have your music sitting on a
PC somewhere.

Does the mobile have a subscription plan; i.e. periodic payments?

Seems to go against the whole ethos of exercising. Never get out of bed and
live forever ...

Blanket absolute statements are often wrong...

You have to match the logic to the device. Light bulbs? Off makes
them last longest. A car engine? You better exercise that sucker
once in awhile if it sits outside fully fueled. Many electronic
devices can tolerate 24/7 with few failures. Disk drives? Now that's
a question. The early ones (sealed ones - not the very early ones
where the platters were removable 12" disks) seemed to do better if
they ran 'til they croaked. The early drum recorders seemed to last
forever as long as they didn't stop running. (the heads rode on a
wave of silicon oil and never touched the belts unless they stopped)

This might be where a Knoppix disk can help arbitrate between a
software/configuration problem and a hardware failure. Any time
I have something fail, I do the "Remove Device"/"Add Device"
dance, then update drivers.

If that fails, out comes the Knoppix disk. If it *still* fails,
it's most likely hardware. I've been lucky so far and nothing
has needed a lot of scrounging for Linux device drivers.

The bits that will fail [first] in a mobile phone are the battery and
display. You can replace the battery and switch off the display.

I have two 40+ year old solid state radios that still work.
