Using mobile phone as an internet radio
Not being able to find a small internet radio to buy we liked, we got mobile
phone with which we link with wi-fi to a modem router, and use it as an internet radio. Keeping the phoned plugged into its charger all the time, we are using it to play *all-day* background classical music through an amplifier and speakers. Since the phone has no 'moving parts' unlike a computer, we are wondering if this continuous playing all day of the phone is going to shorten its working life ? |

It's not nonsense. The inrush current of a cold filament can shorten the filament life. That's why light bulbs usually blow up when you turn them on, not while they're running. The induced magnetic field also tends to "twang" the filament, which can break the filament if it were somehow mechanically weakened. While attending kollege in the 1960's, I worked for a short time as a non-union projectionist at a movie theater. Besides babysitting the projectors, I had to deal with the flashing light bulb marquee. I vaguely recall that there were something like 2000 40 watt light bulbs. Roughly once per week, my job was to replace the blown bulbs from a rickety pre-OSHA 20ft wooden ladder, sometimes at night. I didn't keep count, but every week, we would lose about 20 light bulbs. Doing the math, that means after about 2 years, ALL the light bulbs would have been replaced at least once. At 8 hrs run per day, that's 800 hrs lifetime which isn't all that great, especially since we were running the bulbs at reduced voltage to improve the lifetime. We used the same bulbs in the theater foyer and lobby, where they were NOT cycled on and off like the flashing marquee. I rarely replaced those bulbs and they seemed to last forever. Some web forum ?

With mechanical devices, regular moderate use provides a longer useful lifetime than using the device only rarely. Yes, this is also true with EM (Electro-Mechanical) devices like pinballs and jukeboxes (and other arcade games)- regular use keeps the contacts on the relays clean from their designed in rubbing action (overtravel). If the machine is not used then the contacts tend to oxidize and not pass electrical current well leading to service calls. HOWEVER the topic here is a solid state mobile phone - and that device really doesn't care too much if it is on or off as long as it operates in a reasonable temperature range (around 20 - 35C). Chances are it will be obsolete before it fails if it runs cool to the touch. Heat is the enemy of electronics, mostly capacitors - and their life gets quite short the warmer the operating temperature gets above 50C...just read the spec sheets. Typical electrolytics endurance: - up to 5,000 Hours at 105°C or about 210 days (7 months) running 24/7.

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.

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?

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

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 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 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. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
