Do it yourself.

Now this will not be cheap, but it will be industrial grade and last the lifetime of the house. You will need to do your own wiring and your own programming. If you have basic skills of pulling cat-5 cable and basic home wiring skills, you can do this your self.

You can do this for about $250 and a few weekends worth of your time. You can spend about that much and have a toy system or go this route and have an industrial system.

You will need to start with a parts list.

First, you will need a board to switch everything. Start here.... http://www.ebay.com/itm/OPTO-2...

This board already has some 120v output switching. $31 at current price, there are cheaper that you can find still. But what this board doesn't have is the 120v input modules, they are yellow... Here is a lot of input and output.... http://www.ebay.com/itm/4-Opto...

You still should be able to find them cheaper.

You are going to need a 1000 foot roll of 4 pair 18 guage wire with wire colors white, black, red, green. This is an industry standard... http://www.ebay.com/itm/18-Gau...

Start with that. Depending on your building codes if you can prove that you pulled this wire and it had been there for 5 or more years, you will not have to pull it out when you sell your home.

Now the fun part. You need to find a central location in your home to mount the G4PB24 board and possible others when you expand the system. This place need space to have a computer and a connection to the internet too.

Start with the light switches. You will need to run your wire from your central location to your light switches. Pull off the plate to the switch and run your wire in the wall to this switch. The switch will have two wires connected to it. One from power and one going to the light fixture.

The black wire(in the US) from the power line is connected to to the bottom of the switch.
Connect the black wire from the 4 wire cable you pulled and connect it there with the black wire to power. Do not remove the black power line wire from the light switch.

Disconnect the black wire that runs to the light fixture and wire nut it to the red wire in the 4 wire pair that you pulled.

Connect the Green wire to the switch where you removed the black wire from the switch. The Green wire will carry the switch power.

The white wire from both power and light fixture should be wire nutted together. Add the white wire from the 4 pair wire to those 2 wire nutted. That is your neutral.

Now on the G4PB24 board put a Black OAC5 in position 1 and a IAC5 in position 2 on the board. The black wire and the red wire will go the the 1 and 2 position of the Black OAC5 and the Green and White wire will go to the 1 and 2 position of the IAC5.

When you then throw the light switch, power will be applied to the green wire. That will flow through the IAC5 turning on the LED in the module and flowing out through the white wire. Nothing happens......

You will need this computer interface board to make the magic happen... http://www.ebay.com/itm/Opto-2...

This one is for $199. I have found them as cheap as $35. Keep your eye out for them.

The software that you will write will constantly poll the input modules looking for input and then turn on the corresponding output module. The Black wire connected to the OAC5 is connected to the house current on the same circuit as the light bulb, so no overloading one circuit in your house to power all your lights.

OPTO 22 has a development kit for the PCI-AC5 found here... http://www.opto22.com/site/pr_...
It is FREE.

Turning on the OAC5 in software applies power to the red wire turning on the light bulb. The bad news is if your computer shuts down, then you can't turn on any of your lights. I have a patch panel that all my wires go to first, then I connect the G4PB24 with the input and output relays to the patch panel. That way if the computer ever does go down, I then jumper the green wire to the red wire and the light switch again works as normal.

Rinse and repeat for as many light fixtures that you have. You can use the OAC5 modules to switch anything in your home that runs off of house current. There are other modules that you can use with the board too. Once you have the basics down then start fooling with the others.

As for temperature readings Maxim has a 1 wire thermometer a DS18S20... http://www.maximintegrated.com....

They cost about 2 dollars each in small lots... You have to have a login ID to purchase them... https://memcenter.maximintegra... Registration is free.

You read them from a RS485 serial port. If you have had no problem pulling wire for the light switches, you can use the same wire for these. I use Black to the right leg, white to the center leg and the red wire to the left leg if you don't want to use the parasitic power mode. I've had one of these reading the outside temperature of my house since 1995. Source code to read them is posted on their website.

Read these IC and turn on your OAC5 modules as you see fit. If you want help with writing the software, I have some pretty extensive stuff written already. I have a windows 7 box at my house that is my web server to the world. Via ajax and javascript, my website polls the alarm server for statuses and can turn on and off lights/relays from anywhere in the world, including opening and closing my garage door and ringing my door bell.

Send me an email for help with the software.

Good luck

I have also ridden at a speed of more than 20 miles an hour for almost 22 miles... http://connect.garmin.com/acti...

I would never plan a bicycle ride for where I was not prepared for proper hydration. I don't think any athlete would. I plan rides for where I can stop for water... http://connect.garmin.com/acti...

Any ride less than 50 miles for me even in the heat and humidity, a standard water bottle that will fit in a standard bicycle bottle cage, is plenty of water. I would say any ride more than 50 miles, any one would plan for stops where you can get water.

Carrying this device on long trips would not be practical, nor worth it.

I am a very avid bicycle rider https://nationalbikechallenge....

I came in 1,829 place of almost 50,000 bicycle riders entered into the challenge this year.

I have ridden close to 3,500 miles this year. I have ridden more then 2,300 miles from May to September of this year.

This device would be far to heavy to carry on your bicycle for the little water that it would produce. I also doubt that the battery would last that long to produce enough water. It would be far easier just to carry another water bottle in its place.

If you live in some very rural place with no water and your only means of travel would be by bicycle and you can carry batteries or keep some rechargeable recharged this might be viable. But you would have to wait a really long time for the bottle to fill. By that time you could have ridden to some place that actually had water.

Yes, all of those horror movies are wrong.
.
I have given over 6 gallons of blood in my life time. The most you can give is a pint of blood. One time I was giving blood and the collection bag that his hung on a metal hook broke and dropped to the floor along with the needle that was in my arm. The person that stuck the needle in my arm(I can't remember the medical term for the person at the moment) wasn't sure if the plastic tab was ripped before its use or was torn when the plastic bag was hung on the medal hanger..
.
But, I had only given 1/4 of a pint of blood, so they got a new bag, a new needle and stuck my other arm. Now I only gave a pint and 1/4 but when I was walking out of the place, I was dizzy, lethargic, and all I wanted to do the rest of the day was go home and sleep. Giving blood never affected me like that before or since. It was that extra 1/4 pint that did it to me. A pint and a half of blood and you would be passing out..
.
So yes, those movies are all wrong. .
.
The one movie that is really wrong is Mel Gibson's "The Passion of Christ". In the movie towards the end when he is being hung on the cross, it looks like Christ has lost about 2 gallons of blood. You don't have that much blood in you and well before that time, he would have passed out. Any one would have passed out..

Surprise... Nothing was found..... Good guess though.

I can tell that you are highly knowledgeable about the subject. You may even be in the business. But, all the people searching for the aircraft are also in the business and have come up with ..... Nothing.

Sometimes being in the business prevents you from thinking outside the box. I'm not in the business. I'm not even that knowledgeable about the subject. To me as I see it, switching off equipment to avoid being tracked, in a certain sequence, not all at the same time, tells me it was planned.

True, pulling fuzes to avoid additional fires is common, but then you pull them all at once, every one of them. Not in a certain sequence. Even if you did start pulling them and it took time to find them all because of a fire, you don't go out of your way after that to avoid radar. If in a fire situation at that point, you are not concerned with radar, as you stated... you are flying the aircraft.

I know with you being in the business or even a pilot yourself, you probably think my theory is unimaginable. But place yourself outside of the box and an outside influence happened that is never likely to happen at all, like money being involved or something else, and the unimaginable happened.

You continue the think the most likely to happen as with everyone else, and nothing has been found at all. Now thinking the most unlikely and what do you get.... something like I am telling you.

My point again. There was at least one person alive that knew how to fly the airplane that made the course corrections to avoid radar.

You don't avoid radar if you are under duress of a hijacking or looking for an airport to land at because of fire. You are avoiding radar because you don't want to be found. Then again, (as the parent states and the grandparent see differently) maybe the pilot was taking the plane to Africa to sell for parts, and the two people aboard had nothing to do with it.

It will still be found off the coast of Africa because it ran out of fuel.

Fact 1. There were two people on the plane headed to Europe. You don't go to Europe via China.
Fact 2. They were flying under assumed names, stolen/purchase passports. They had money and connections..
Fact 3. The airplane made an unscheduled turn off of the flight path via the pilot. Possibly under duress possibly not..
Fact 4. The two people going to Europe were cleared from terroristic activity. .
Fact 5. The plane flew for another 5 to 7 hours after the unscheduled turn off of flight path..
Fact 6. The only people capable of flying the brand new aircraft where the pilot and co-pilot. Further course corrections verifies that the pilot survived to the end..
Fact 7. The only people capable of knowing the correct sequence of what to turn off to avoid being detected were the pilot and or co-pilot. Under duress that sequence would not have happened. And this is the most important fact, the pilot was not under duress..
Fact 8. For the plane to make it to Europe even if being hijacked, it would need to be refueled. .
.
Simplest answer to all the facts:.
.
Pilot was paid to make the unscheduled change in flight. The pilot after years and years of flying was going after his final payday. And it was probably an offer he couldn't refuse..
.
The pilot knowing that the plane needs to be refueled would know the best places to refuel. The middle east is not the best place to obtain fuel undetected, especially with the presents of military forces and all radar use in the area. They were trying to avoid radar just after takeoff..
.
Best places to land and refuel, Africa. It is only slightly out of the way to Europe. The one problem, The plane didn't have the range that the pilot thought it had. .
.
The plane was ditched 100 or so miles off the coast of Tanzania, or Madagascar. They ran out of fuel..
.
You don't go flying an airplane for 5 to 7 hours just to ditch the plane the farthest place from all human existence. 5 to 7 hours is a long time to contemplate your death. Flying for 5 to 7 hours more, there was a destination to get to. Who knows the final destination but they were flying to get somewhere..
.
If the intention was to commit suicide and take all passengers with you, you do it as quick as you can. People that blow themselves up in a market square, don't walk in order coffee and sit there for 5 to 7 hours waiting for the best time to blow themselves up. You walk in look for the best place and get the job done..
.
Also why do it out over open water when you can do it near land or on land and make a statement too? .

I went to Georgia State University way back when. I was going as a CS major and I was taking a Chemistry class as an elective. I was doing horrible in Chemistry as I was a full time student and had a full time job too.

I struggled through the class and the lab. For some reason the final exam was in the computer lab. As I found out the exam was on the computer and had a time limit of 4 hours. To show how long ago it was, the exam was on commodore 64's.

It was a 200 question test and multiple choice. I struggled through the first 15 questions for almost the first hour. I decided that I was never going to finish the exam in time. I had fooled around with commodore's prior and knew the execute break sequence.

It dropped me to a command prompt and I started looking through the code to change it so no matter which answer I gave it was always correct. 10 minutes of searching through the code, I found where it matched up responses to questions. The bad news if anyone remembers programming for commodore basic is that you could lock the program memory.

The good news was that I found the variables holding the question I was on and the number of questions that I got correct. I set the next question equal to 200 and the number correct to 199.

I sat around for almost another hour. Then at the command prompt typed "run" and pressed enter. A screen popped up stating that I completed the test with one missed answer at a time of just over 2 hours.

I got an A in the class and nobody ever questioned my final exam test.....

Was that moral?

The one thing that you are forgetting is willful rerouting. Say the pilot is looking for a payday of all paydays.

There were two people going to Europe. They had fake passports to board the plane. Somehow there were going to Europe AND not through China. China is the wrong direction for them. They were not the type to hijack the plane nor had experience to fly the plane if they actually did that. They have been cleared.

But say they had money to bribe the pilot to go to Europe. What is the best path to make it to Europe undetected. You don't fly through the middle east AND you are going to need a place to refuel. It would be much easier to refuel in Africa than in the Middle East somewhere.

The plane is off the coast of Tanzania or Madagascar. They were hoping that there was enough fuel to make it but had to ditch it a few 100 miles off the coast of either one. It wasn't a hijacking, but a paid rerouting.

That is where the plane will turn up in a few years. Oh and the satellite data they have isn't correct. Well, it is correct but it wasn't plotted correctly.

It sounds like an old Window 95/98 flaw that was almost similar. When signing on to a user account, a dialog box would pop up with the user id already filled in. Type in a wrong password, it would give you an error dialog box that you had to press "Enter". When enter was pressed it would clear out the user id and password. If enter was pressed again without entering a user id and password... it would sign you in to what ever account you were originally trying to sign in to.

My son has been diagnosed with autism because he doesn't talk to anybody and he is 3 1/2. The problem is he just doesn't feel like talking. I was the same way when I was a kid. My mom says that I really didn't start talking until I was 5 years old and had started school.

Nowadays that gets you labeled as "Autistic".

At 2 years old, I taught him how to say the alphabet. At 2 1/2 years old I had him writing the alphabet. I don't know many children his age that can write the alphabet even now.

I read to him now every weekend that I have him. As I read the book to him, he points at the correct words that I read. That to me says that he is smarter than average.

If he generally wants something, he will point at it and say nothing. He has done that most of the time in the doctors office when they try to evaluate him. He will speak if made to as when he wants me to pick him up, he will come to me and tug on my arm. I will wait till he says "Up" before I pick him up. I most times have to ask him what he wants a time or two but will usually say it in a minute or two. Oh and his mother only speaks Spanish, so that might also be confusing to him too.

I know that he is smart because his mother will put on a Dora DVD at night for him to go to sleep and turn the volume all the way down not to disturb her other children. He has recently started saying out loud, the entire dialog of the video as it plays when there is no audio. So, not only can he speak, but he can remember the entire spoken content of a 2 hour video at age 3 1/2.

He will be fine, just as I was.
