Using mobile phone as an internet radio

life ?


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

Using anything shortens it's working life.

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)

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...

Boot times are largely a function of what gets loaded prior to showing a
"desktop". Different OS'es have different boot times. Check out Haiku
OS. I boot to a "desktop" in under a minute.

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.

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.




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.

Be sure to use all ten fingers on the tv remote, make them last longer.

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.

The TV, the remote, or the fingers?

Except phones with hardwired batteries.

My 39YO HP45 still works but the power switch is too flaky to be usable.

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.

It's an accelerated life test. The deration curve of the incandescent
light bulb is well known and assumed to be
(Vapplied/Vdesign)^-12 to ^-16 * Life at design voltage
http://www.welchallyn.com/documents/Lighting/OEM_Halogen_Lighting/MC3544HPX_Catalog_2_11_09.pdf
See Fig 5 on Pg 5 for the graph. Nobody wants to wait 1000 hours for
a bulb to blow. So, they increase the applied voltage, which
dramatically decreases the lifetime down to reasonable test times.
Using a rack of bulbs, they obtain an average (or median) lifetime at
the higher voltage. Then, they work backwards on the curve to
estimate what it would be at the design voltage.

When I was specifying lamps for a direction finder for the USCG, I had
to deal with minimum lifetime specs. I asked the vendor (Dialight)
how they tested their T-1 3/4 bulbs and was told that they did an
accelerated lifetime test on a few bulbs from each lot to insure
adequate lifetime along with the usual sampled 1.5% AQL failure test.

Electromigration is a smaller effect in an AC bulb, since
the leading order effect cancels.

Yep. As I understand it (possible wrong), AC filaments break in the
middle, mostly from vibration flexing.

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.

Yep. See my comments on the relatively high failure rate on the
40watt theater marquee lamps due to cycling. The same lamps in the
lobby and foyer were not cycled and seemed to last forever.

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.

Yep, but different failure mode. When the extremely thin layer of
tungsten plating evaporates, the light becomes dimmer. Below some
brightness level, it is considered to have failed. However, most such
tungsten coated filaments fail due to corrosion of the base steel
alloy wire which is exposed to the internal gases inside the bulb
after the tungsten evaporates. The gases (mostly nitrogen and some
argon) are inert, but there's a little water vapor outgassing from
heating the glass envelope, which eventually corrodes the filament.
Other failure modes are hot spots and notches caused by manufacturing
variations and tungsten evaporation.

It may be bad for the battery
