Period Punctuation in Writing

PERIOD:
The use of periods as punctuation in writing.

The primary uses of the period are:

a)      At the end of a sentence, when the sentence is a statement or instruction.
 Example: 

      Please have those reports completed and on my desk by Friday.

b)      After an abbreviation or after initials.
 Examples:

      Gov’t.                      etc.                   I.R.S.                John W. Smith

c)     It is acceptable to omit the period after an abbreviation that consists of the first and last letter of a word.
 Examples:

             Mr.  or   Mr               
             Dr.  or   Dr

d)      When abbreviating, for example calendar months, titles, degrees, or days of the week, it should be remembered that only one space follows the period at the end of the abbreviation, and that no spaces follow the letters within the abbreviation.
Examples:

             U.S.A.   not   U. S. A
             Ph.D.    not    Ph. D.

e)      If a sentence concludes with an abbreviation that ends with a period, a second period should NOT be used
 Example: 

       This matter will now be referred to the I.R.S.

an important message for Chris Church

Hi, I record a show every now and then, although not very frequently, and I have a question about microphones.

I was reading in a different thread that it is possible to build a pair of your own mics with a little bit of soldering and ingenuity and some omnicaps. I was thinking this might be an interesting venture- just to try it out and experiment a little. But before I do that, can anyone attest to this actually working? Just in general, what is the quality usually like? I have a mic that works fine for me right now, but I think this would actually be an upgrade if it worked since the frequency response on these omni’s seems to be a little wider.

Thanks for any response.

You can build mics for cheap, that sound very good. Here is a source of WM-60 capsules these are the same ones earthworks uses in the m-30 mic
You can order hand matched calibrated capsules from this guy they are more expensive but you will end up with a matched pair of capsules. I would be very careful about the mods to this capsule they are hard to do but the mod that I do is a simple 4.7 k metal film resistor between the ground pad and the capsule ground pad on the back of the mic the trace between the capsule ground and this pad must be cut with a razor.

You must have a good set of radio shack heat sinks they only come in a kit that includes a bunch of soldering iron tools they are like aluminum alligator clips but they are flat you clamp both of them onto the capsule when soldering them, its very important to be fast with your soldering and have a very good like and a good pair of eyes. But it can be done if you can afford to buy two sets of capsules you should here is the contact info for these capsules.
Its also very important to have a great soldering iron with a very fine tip. This can be an expensive thing to get into, but it can be very rewarding I use brass tubes from a hobby store for my omni mics and I use epoxy to glue everything together with some heat shrink and remember the tube that the mics sit in is very important to the sound with out giving away to much information on what I do and others like earthworks its all about what the capsule is placed in even more so then the capsule it self that determines the frequency response of the mic. Shielding is very important to reduce noise. So look around on the Internet. let me know if I can help you out I would be glad to.

I do my own matching when I build mics this is possible because I have 1,000's of capsules when you buy one or two from digikey its very hard to get a good match. Kim has been doing this for a long time and is very good at it.

What the hell does owned mean? this must be some sort of US thing.  I think your very funny for a studio engineer wannabe.

Thanks for the great tips, Chris.

I started out the exact same way: just ripping the ends off a set of cheap "earbuds" and soldering capsules on the end.  Then I epoxied them, etc.  This is a great way to start.  When you're done you can give  get them started too...
