  2. Re:Static Control on Conductive Concrete Offers Building Security · · Score: 2
    Regular concrete is already so conductive that electrical codes require it to be tied into the grounding system of the building of which it is a part, and one of the acceptable ways to construct a building's main grounding point is to embed a length of metal pipe in the concrete of the building's foundation (assuming direct contact between the concrete and the actual planet Earth.

    If you're standing barefoot on a damp concrete floor and come into contact with a "hot" or "live" wire, you'll learn very quickly (within one/one hundred twentieth of a second, or one/one hundredth for 50Hz locations) how conductive concrete can be, assuming, of course, that you survive the lesson.

  3. Re:Properly cleaning a fan... on PC Fan of the Future? · · Score: 2
    Excellent tutorial, but use automobile ignition lube instead of petroleum jelly.

    Also suggest de-natured alcohol for cleaning and saving the rubbing alcohol for the medicine cabinet. A pint of de-natured will cost you 5 or 10 bucks, but you can use the rest for a year or three of cleaning other electronic stuff (with the power OFF!), including floppy heads and CD drive lenses.

    I believe that you meant to say that it is the cheapness of the bushings, not brushings. As you point out, these motors are usually brushless (and a good thing too, as brush-type motors are even noisier, both acoustically and electrically).

    As for that single washer, a little automobile ignition lube (one of the brand names of which is Ignition Lube) packed in around the washer already present does the trick nicely. Anyone needing to know how to disassemble their fan to apply it, e-mail me.

  5. Re:How tachometers work... on Analog Tachometer PC Mod · · Score: 2
    It's been a long while since I looked into (or cared about) hooking up a tach, but I'm pretty sure it gets a parallel feed of the pulse stream from the points (or electronic equivalent) to the coil primary. In other words, it gets a pulse every time that any plug fires (or misfires, for that matter).

    I can't remember if the crankshaft makes one turn or two for every rotation of the distributor but either way the faster the engine is turning the more pulses per unit of time. These pulses are fed to a capacitor which smoothes them out into a "steady" DC which rises and falls as engine speed does.

    The tach is basically a DC voltmeter that reads that voltage level on the capacitor. Some tachs have a switch or jumper to change capacitors or change the resistance in a resistor-capacitor combination so that you can set them for either an 8 cylinder or 6 cylinder engine (for 4 cylinders set it for 8 and divide the reading in half).

    Amen to that. Of course I lost all respect for Time when they wimped out on Bin Laden as "Man of the Year" (not nice guy of the year but person who most affected the news. Of course last year they named Dubya, when the obvious choice was "Chad" :-) Also we have to rely on Time-Warner for cable TV around here, and you can guess how thrilled I am about that.

  8. Re:The RIAA wants to sell the same crap forever... on Consumer Technology Bill of Rights? · · Score: 2
    Because Disneyland and Walt Disney World have "gay days" and because Disney extends benefits to "partners" rather than just opposite sex spouses of employees, some of the churches affiliated with the Southern Baptist Convention launched a boycott of everything Disney. So far it doesn't seem to be taking all that big a bite out of Disney's bottom line.

    Note that this is not something being done by every Southern Baptist church in the known universe and that there is no way that the Southern Baptist Convention could enforce this upon them. Churches affiliated with the SBC are independent organizations (as are just about any flavor of Baptist church) and that the Baptists were a big part of the inclusion of separation of church and state in the Bill of Rights, although this was due more to their desire to protect religion from government than the other way around.

    Is Newsweek owned by some conglomerate that also owns record companies, music studios, etc. the way that arch-rival Time magazine is? I applaud them for making the points which they did, but to what extent was it done to rag on Time-Warner AOL?

    You're quite correct about print media being willing to spend a little more time than the length of a sound bite on a subject.

    But they aren't competing. In my neighborhood the company with a monopoly on cable TV (Time-Warner) offers a choice-Roadrunner or AOL, both owned by Time-Warner. My experience with them as a cable TV provider has me convinced that they are my last choice as ISP, right behind tin cans and string. In order to stay with my current ISP (and my current e-mail addresses), I have to stay with dial-up. Sprint has been saying "real soon now" about DSL for about 3 years now, and I suspect they're waiting until they can offer it only for ISPs that they own. The only competition going on is between these giant corporations to see how big a monopoly each can become and how fast they can do it.

    There's not much reason for a U.L. approved light bulb to have a fuse. If it dead shorts, the fuse or circuit breaker for the circuit that the light is on is supposed to interrupt current flow. If it merely attempts to draw more current than it should the filament will probably burn out, which will interrupt current flow as well as any fuse.

    Actually the bulb wouldn't be U.L. approved, it would be U.L. listed. What U.L. does is tests stuff to make sure that it fails safe, not to guarantee that it doesn't fail. They don't care if the light bulb burns out, they care whether it starts a fire or lets someone get shocked or electrocuted from touching something that shouldn't be electrically "hot".

  19. Re:Grammar. on Digitizing VGA? · · Score: 2, Flamebait
    The way to get it right is to eliminate the second party momentarily and ask yourself which sounds right, "...perhaps I might be able to...", "...perhaps me might be able to...", "...perhaps myself might be able to...". The right choice is usually blindingly obvious.

    A little less clear in this instance is who gets top billing. Ordinarily you would list yourself and a second party as "...foo and I...", but in this case the "...someone else here..." isn't someone acting in concert with you, but as a second source only to be called upon in the event of your failure to help satisfactorily, so I believe the "first one and then perhaps the other" sequence makes "...perhaps I or someone else here..." the better choice of wording in this particular case.

    How would you feel if you were publicly called "crooked" solely on the basis of rumours? Especially if it was in a place and a way that could negatively affect your net worth (stock price, for the company)?

    Without seeing her exact words, we can't know whether she expressed her opinion as opinion or as fact.
