Can you make a red laser pointer into a high powered laser?
The answer is pretty much "No." You can increase the power slightly, but if you go much beyond what it's designed for you'll burn out the laser diode.
Who makes early warning brand radar detectors?
A now bankrupt company called SK Global America makes the Early Warning detectors.
What are two categories of laser printers?
Printers can be categorized in a number of ways.
There are inkjet and laser printers. Inkjet printers use ink cartridges while laser printers use laser toner cartridges.
Also, printers can be classified as colored or black.
What is a Unidirectional microphone?
That is a microphone which receives the sound only from a small angle of direction; like a gun microphone.

Is it OK to write on a DVD r with a marker?
You can use a marker to label your DVD-R (or DVD+R). Simply make sure you are obviously not marking on the side of the disc that you are burning on. If it's a double-sided DVD, then you're obviously not going to mark on either side.
Also make sure you do not use a sharp tip marker which may damage or scratch the surface of the DVD. A standard Sharpie marker should do the trick.
Can the Japanese PS3 version play PS3 games from Africa and Australia?
PS3 games are not region coded, so you can play Japanese PS3 games on a PS3 from North America or Europe.
On the other hand, PS2 and PS1 games are region coded, so you can only play those games (if your PS3 has backwards compt.) on the same region PS3 model.

When were DVD's first introduced to the public?
DVDs first appeared in 1995, although they did not overtake VHS for some time after that.
If an electrically uncharged body is contacted by an electrically charge body then the uncharged body will gain a charge. This is because electricity flows from a higher concentration to a lower concentration and will balance out.
When did windows 2.0 come out?
Microsoft Windows 2000 is a computer operating system that was succeeded by Windows XP. The original released of Windows 2000 was on February 17, 2000.
What is a television designed to do?
The television revolutionized the way information is disseminated to large populations. For the first time in history, large populations of people could received the same information in a single setting (though the information could be interpreted differently) allowing for little degradation (improperly redistributed information from a third party source).
Where can you get a free internet phone number?
You will most likely not find a free phone unless it is a scam. Wireless carriers offer subsidies on a lot of phones when you sign a contract with their service and sometimes those subsidies are high enough to make the phone free. I would recommend checking with local wireless providers and see if they can help you out.
What is meant by the term wireless revolution?
Is means in simple terms the replacement of wires used for communication to a wireless environment. For example, local area network (LAN) has been replaced by WLAN (Wireless LAN), similarly fixed line telephones have been replaced by mobile hand sets including satellite handsets.
What happens when you put metal in a microwave?
Running a microwave oven with metal in it will result in the reflection of the microwave energy off the metal. There is an exception, and that's the problem. Let's look at that.
If metal in a microwave is in a certain shape, that is, if it has a certain geometry, it can act as a microwave antenna. It can cause the microwave energy to generate "specific" electric currents in the metal, and voltages can spike high enough to create electric arcs in the cavity. That's bad. We can use metal in a microwave (like to cover the ends of drumsticks), but we must follow the manufacturer's instructions when doing so.
vxworks is used to control network and communication devices. vxworks is similar to unix but it uses less processing power than unix.
How do you program a uniden bc 142xl scanner?
When you set up a Uniden Bearcat BC148XLT base scanner, you must program the frequencies you want to scan based on your area's frequencies. You do not need to include weather frequencies, because the BC148XLT includes weather frequencies pre-programmed in the base. You can add frequencies to your scanner in minutes, allowing you to customize the frequencies you scan.
Press "Manual" to stop the scanning process. Press the number for the channel you want to program using the keypad on the scanner base. Press "Manual" after the channel number.
Enter the frequency, including the decimals, using the buttons on the keypad.
Press "E" to store the frequency.
How does thickness of a wire affect resistance?
Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance.
The resistance R = l p / A
where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section.
So R the resistance is inversely proportional to A the area of cross-section. If R increases
The car radio was invented in Chicago, Illinois, USA by Robert Galvin. He went on to found a company named for his new product: Motorola
Unofficial/undocumented Answer:
Neal Kyser McNaughten (and probably others) Although there is no documentation to prove it, my father, Neal Kyser McNaughten, born in 1911, built a radio into a Model T some time in the late 1920s. It had a paper cone and used it's own dry cell since the car had no battery. He claimed that it was particularly of interest to the young ladies...
What is a cassette player used for?
Cassette cases are used to store and give protection to cassette tapes. These cases help prevent the cassette from getting broken, cracked, or damaged.
How do compound machines work?
A compound machine lets you trade out energy force and effort. Example: If you have a wheelbarrow and 50 pounds of bricks what would you use your bar hands are the wheelbarrow. Of course the wheel barrow cause it is much easier to use.
How do you type a heart on an iPad?
The iPad Facebook app does not have emoticons, but you can add them by installing apps like Emoti HD. These programs work for posts and updates, but not for comments.
Logic gates are transistor circuits, normally arranged on a silicon base and encapsulated inside an integrated circuit. (chip).
Using several transistors wired together, their inputs can be arranged such that, for given inputs, the output will only change state for certain conditions.
The transistor switches are in either of two states, 'on' and 'off'. These are logic states 1 & 0 (one or zero), hence binary.
The logic uses Boolean algebra.
NOT, means it is 'not on', = OFF. This is abbreviated in the descriptions as the letter 'N'
A simple AND gate, means that the output is at level zero until both inputs have a level 1 voltage on them.
A NAND gate is a 'Not And' gate. The result is reversed. The output is always at logic level 1 until both inputs also have a level 1 also.
