Seriously the TSA just needs to stop issuing statements considering it has become blatantly obvious they do not operate according to their own policies.  It is nothing more than sponsoring child molesters and pedophiles to prevent their arrest.  Don’t believe me, here’s TSA’s statement regarding pat downs of children under 12.

"After a thorough risk assessment and after hearing concerns from parents, we made the decision that a modified pat-down would be used for children 12 years old and under who require extra screening," TSA spokeswoman Kristin Lee said in a statement.

Pistole then modified that statement to the following:

Indeed, the only “change” to the TSA’s policy is that it now says it will “make every effort” to exempt children under 10, where as before it said all children under 12 were unequivocally exempt.

Don’t believe me, some TSA pedophile felt that a 6 year old boy heading to Disneyland on a surprise trip.  He got not one, but two pat downs, and did it severely enough to where he didn’t want to go anymore.

The better half saw two people in TSA uniforms in Pullman recently while filling up Lite.  I was a bit bummed I wasn’t there because I’ve reached the point where I have no issues with verbal harassment to make them feel uncomfortable.  If I’m not flying there is absolutely nothing stopping me from voicing my opinion of those jack booted thugs.  They are doing more than any other government agency to abuse the citizenry and turn this country into a police state.  If you see an TSA agent in uniform outside of an Airport, please make their lives as uncomfortable as they did to this little boy.  While you can’t get physical, you can make them feel ostracized.  They have created this us versus them atmosphere and it’s by time we start playing ball on our court.

Note: Do not get physical, just verbal, exercise your first amendment to cause them to be uncomfortable.  Now if while you are verbal, they resort to being physical, at that point feel free to defend yourself.  These ass hats want to spread to malls and searching vehicles while traveling, at that point they’re absolutely on our turf and it’s time to fight back.  When people who lived through the Soviet terror think that our country has turned into the USSR, it’s time to listen to those who have lived through the horror.

I’m finishing up the last of the prep work on the boat and am working on some MP3 playlists for the boat tomorrow while I cool off.  Any recommendations of must have music for the water?  I listen to just about anything but pop.  Forecast for tomorrow is 90s, water temps approaching 80, it should be a blast, just need a good soundtrack for it.  Drop your suggestions in the comments!

I picked up the tie’s for Joe for Mecca.  My truck bed is currently full of creosote packed timber.

That’s going to be dropped off on my way to the lake.  Hope everyone has an awesome weekend.  Send me any ideas you have for music for the boat.

I never really bothered to pay attention before, but there’s a LOT of Remington 700’s at Boomershoot.

Seriously, I just walked down the line taking pictures and I’m finding that most of them are 700’s. 

I know most of you won’t get most of it, but for those who do, this currently is what my life feels like.

Four years ago today I married my wife and best friend.

Yes that’s an eagle perched over my port shoulder.  And shortly there after she tossed me her bouquet and ran off.

No I haven’t forgotten, happy anniversary sweetie.

So in the second entry of the Power Series, before digging into the details of generation, transmission and distribution, there is some basic circuit theory that needs to be covered.  This week I’m going to cover DC basics and next week my goal is to cover AC circuits and power fundamentals.  Without this information many different things won’t really make sense so here’s a quick primer on the fundamentals.  This is like a layered cake, once you get higher up you no longer care, but the stuff you do see requires an understanding of this first.  For some this isn’t necessary, for others who have absolutely no clue this can be handy.  I’m not going to roll back all the way to the basic physics principals and electron charge.  I’m already pushing limits here on the blog, I’m not even sure currently how this fits with my theme.  Frankly I don’t care cause this is more fun to write about than how fearless leader put his head up another orifice.

Some of this will be a very basic review and obvious to some.  My original goal was to try and avoid using math because I know it will scare some away.  If for some reason you lost in the math, move forward, it may become more visible later on, or ask a question where you’re lost in the comments or contact me.

Current and Magnetism:

Current is merely the flow of electrons.  Electricity and Magnetism are closely related to each other.  Current as it flows through a wire induces a magnetic field.  Just the same moving a wire through a magnetic field produces a current.  This principal is governed by Faraday’s law of induction.  This simple principal is why electricity is so prevalent, easily generated, and so useful.  It allows us to covert mechanical energy into electrical energy and back again.

Ohm’s Law:

There are three fundamental items when it comes to electricity:

1. Voltage, also known as potential difference.  This is analogous to the pressure on a water pipe.
2. Current. This is analogous to the volume of water flowing through the pipe.
3. Resistance.  This is analogous to the diameter of your pipe holding your water.

All three are related by what is known as Ohm’s Law:

E=I*R

The current through a conductor between two points is directly proportional to the potential difference across the two points, or more that as resistance or current increases, so does voltage.  This can be thought of again by using the water example.  When you use your thumb to close off the end of a hose, there by increasing resistance, the pressure increases.

More on Resistance and Wires:

Even conductors have a resistance associated with them.  Normally it is considered insignificant, however when dealing with very long wires the resistance can no longer be totally ignored.  Every material has a resistance associated with it.  There are three components associated with finding a resistance of a wire.

1. The material it is made of.  Copper, Silver, Gold, Iron, Steel, etc.
2. The length of the wire.
3. The cross-sectional area.  (Diameter of a wire)

Different materials have different conductivity values.  For instance copper is a much better conductor than steel for example.  The larger the diameter of the wire, the better it conducts because it is not forcing all the current into a smaller area just like a hose.  Mathematically this is described as follows:

ρ is the resistivity of the material in question.  Normally we just look up the values of the material in a table.

Resistance also comes in the form of a resistor, some of these leverage the principal of the resistance of long wires and are merely wire wraps so electrically the length is long, but physically it is short.  Others make use of exotic materials to limit the flow of electrons.  Ultimately though they are little black boxes which provide varying degrees of electrical resistance.

More on Voltage:

Voltage is the pressure that is being applied to move the current it is a measurement of the electromotive force.  This is usually what most people know when dealing with things like batteries, their wall socket, or other electrical equipment.

Basic Circuit Principals:

A resistor creates a drop in voltage across it when there is a current flowing through it.  This drop can be found by using Ohm’s Law.  We are going to start off examining series circuits.  So to start with say we have the following circuit.

This circuit is a series circuit and is defined as such since all the resisters are in series with each other.  The total voltage drop across the three resisters is 20 volts, that is split across the three resisters.  To find the drop across each resister you first need the current flowing through it.  Since this is just a series circuit the each resister is cumulative to the previous one.  This means the total resistance for the example circuit looks like the following.

We can now use Ohms law to find the current.

Now that we have the current flowing from the voltage source through the whole circuit we can determine the voltage dropped over each resistor.

This now brings us around to one of Kirchoff’s laws, this one being his voltage law.  It directly states the following:

The directed sum of the electrical potential differences (voltage) around any closed circuit is zero.

More simply all the voltages across drops and sources within a closed loop must sum to zero.  In this circuit example we see that is true.

After the series circuit we find another type called the parallel circuit.  This is similar to the series circuit but the resistances are next to each other.

Resistance in this case becomes an interesting beast.  In this case each path allows a different current depending on the pressure, we’ll work backwards to find the equivalent resistance seen from the voltage source.

Since each resister has a voltage drop equivalent to the voltage source, finding the current through each resistor is simple.

This brings us to Kirchoff’s Current law which states the following:

The algebraic sum of currents in a network of conductors meeting at a point is zero.

Otherwise put as your input always equals your output at a junction.  With that we find that the source is providing 10A by adding all three individual currents.  With that we can now determine the equivalent resistance of the three resistors in parallel.

Ass you can see, adding loads in parallel to each other decreases the electrical resistance.  It’s not really necessary but for reference to find the equivalent resistance of a parallel network you use the following formula:

So there’s coverage of the most basic component and formulas, now I’m going to talk about the other two basic components.

Inductors and Capacitors:

Inductors and capacitors both rely on different parts of electromagnetism to explain their behavior which is different than the resistor.  Both components

Capacitors:

Capacitors are quite simple in design and principal of how they work.  A capacitor is merely two conductors separated by a dielectric material.  Examples of dielectrics include, paper, glass, vacuum, and even air.

Capacitors store electric charge on their conductors and it’s capacity is defined as the amount of charge stored for a given potential.  This most simply described is like a small water tank, it stores charge and releases it when the potential drops.  There are two ways to look at a capacitor, the voltage across it, or the current through it.  If you do not know calculus, skip over these two equations I’ll explain them.

The first equation, the one to determine the current states that the current from the capacitor is proportional to the change in voltage.  If you had a capacitor who’s potential measured the same as a DC source that wasn’t changing and a resistor next to the capacitor, the current coming from the capacitor would be zero.  However if the voltage source was disconnected, the current would spike flowing from the capacitor through the resistor while it discharged.

The voltage of the capacitor is found by accumulation how much charge has been stored and then adding on the initial voltage.  For instance if you you have a resistor in series with a capacitor and you close a switch connecting them to a source.  Eventually the capacitor will become full and current will stop flowing from the voltage source.

A simple RC circuit with a plot of what’s happening:

Here is a plot of the voltage and current across the capacitor over time after the switch is closed.

Green is voltage.

Yellow is current.

If you want details on the math of how to describe those curves please ask, the precise math isn’t as important as the general concept of how the voltage and current are behaving.

Inductors:

Current when flowing through a wire creates a magnetic field, changing magnetic fields induce a current in a wire.  Inductors leverage this fact by coiling themselves up to take advantage of that magnetic field.  What the capacitor does for voltage, the inductor does for current.  Again if you don’t understand the math read the parts after or ask questions.

As the current decreases through the wire decreases, the magnetic field collapses causing more current to flow out.  Lets look at the following circuit and plots to see how it compares to the capacitor.

The plots are almost an exact inverse of the capacitor.

Notice how the voltage and current curves have swapped their positions.

The main thing to remember regarding capacitors and inductors is that capacitors resist changes to voltage while inductors resist changes to current.

Notes:  Regarding capacitors and inductors there are some details I didn’t cover such as time constants.  I also didn’t cover RLC circuits mainly due to time, complexity and the details of RLC circuits shouldn’t be required.  If you have questions, or would like me to cover this for your own personal gratification, ask please.  Otherwise I will focus on getting to the meat and potatoes as quickly as possible.

Also condensing this down into a simple form for most anyone to understand is more difficult that I thought, please ASK QUESTIONS!

It is not choice then, but necessity that calls for Independence as the only means by which foreign Alliances can be obtained ; and a proper confederation by which internal peace and Union may be secured.  Contrary to our earnest, early, and repeated petitions for peace, liberty and safety, our enemies press us with war, threaten us with danger and Slavery.

Richard Henry Lee: June 2, 1776

[One month later the thirteen colonies would vote unanimously on his resolution for independence.  John Adams had this to say regarding the passage of the Lee Resolution.]

Yesterday the greatest question was decided which was ever debated in America; and a greater perhaps never was, nor will be, decided upon men.  A resolution was passed without one dissenting colony, that those United Colonies are, and of right ought to be, free and independent states.

John Adams: July 3, 1776

[Frankly I couldn’t put it better myself.  Enjoy your Independence Day, and remember at the end what it really means.  -B]

For those who think that Independence Day is only celebrated by the “right wing” get off your high horses and wake the hell up.  The role of the Declaration of Independence in our country is rooted to the core.  If we didn’t have that, you’d be drinking tea, eating crumpets and saying, “’Ello, guv’na".  I personally hate British tea, it tastes like shit and it only belongs in Boston Harbor.  Crumpets are nothing to write home about, and as for the speech do I really need to explain that?

These ass hats don’t even know how to run a proper survey, twist statistics, and then say celebrating the birth of America is supposedly the bastion of “right wing quacks”.  This coming from a bunch of pricks who roll out on May 5th and celebrate Cinco de Mayo, yet they abhor American Independence.  They are nothing but a bunch of shit-hooks who belittle those who understand American culture and ideals.

Who the hell do these people think they are?  They are slandering one of the greatest achievements of one of their own alumni by playing the partisan game.  For what?  American Independence has absolutely nothing to do with partisan politics.  Those who attempt to taint it as such do nothing by expose their anti-American sentiments.

Then again some may dismiss my statements because of the following facts about me:

• I’m a red blooded American who’s direct lineage has been here since the 1600’s.  Fought those dough-assed British and told them to get the hell out. 
• I’ve actually read the Declaration of Independence, know the history of why it happened.
• I hate social programs, social policies, and redistribution of wealth.
• I’m a rabid capitalist.

I guess that makes me brainwashed by the “right wing”.  Interesting that since I hate the republican party and I am staunch libertarian in every way.   How much so?

• I hate the war on nouns, drugs, guns, sex, all of it
• I hate any and all forms of discrimination, gays, minorities, gun owners
• I hate laws which create victimless crimes, owning something isn’t a crime, hurting someone or damaging someone else’s property is.
• I think there should be flat taxes, why should anyone pay more in taxes than anyone else?
• I don’t believe in using the force of government to take from others to give it to me.  This is what’s happening with low income people electing others who will raise taxes on those who make more to get more government support.

Neither party supports any of my overall stances on things.  Some would call me a right-wing nut because I do not like socialism, communism, or public welfare.  Ultimately I want personal Independence, which was something that the Declaration helped start.

Again, if you haven’t read it, please do.  Most only really remember the beginning of the second paragraph and that document as a whole speaks volumes as to why this day is so damn important.  After reading it, you realize we must be so thankful we had someone so obnoxious and disliked on our side, who saw the writing on the wall, and fought to give us something better.

Many forget how hard our founding fathers tried to prevent moving to independence.  It was a decision that wasn’t taken lightly, and when all the facts were viewed together not much choice was left.  It was at that point it was obvious that something needed to change.

So 235 Years ago, July 4th, 1776, we formalized a letter, signed by our elected representatives that told that fat fuck King George to go piss up a rope.  Mr. Hancock made sure to sign with such conviction so that Fat George could read it without his glasses.  I celebrate July 4th to remember the document that was written to explain to the world why we declared ourselves to be independent from Britain.  To remember what those men risked in doing that and their conviction behind that statement. 

And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

And lastly to celebrate the freedoms and liberties that came with it, that no other place in the world has.

Frankly, if you live here and don’t want to celebrate Independence day, pack up your shit and get the fuck out.  Doubly so if you attempt to turn it in to a partisan cesspool for your own political gain, I’ll help you pack and buy you the freaking one way ticket.

A note: Pardon the language above, I’m sure my mom will read the above and I’ll get a phone call.  Frankly this whole thing has me extremely pissed off and I could have always delivered something like this instead.  I do swear from time to time, usually when I’m frustrated, annoyed, or just down right pissed off.  This article was written with a combination of the last two. H/T to Kevin on the other response.
