Electronics 1 Lab Project
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the secondary winding. This effect is called mutual induction.
If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np).
By appropriate selection of the ratio of turns, a transformer thus allows an alternating current (AC) voltage to be "stepped up" by making Ns greater than Np, or "stepped down" by making Ns less than Np.
In the vast majority of transformers, the windings are coils wound around a ferromagnetic core, air-core transformers being a notable exception.
Transformers range in size from a thumbnail-sized coupling transformer hidden inside a stage microphone to huge units weighing hundreds of tons used to interconnect portions of power grids. All operate with the same basic principles, although the range of designs is wide. While new technologies have eliminated the need for transformers in some electronic circuits, transformers are still found in nearly all electronic devices designed for household ("mains") voltage.

Mapping Party in Davao
The Davao online mappers will be launching a mapping party that would cover every nook and cranny of Davao City this coming July 4, 2009.
This is a whole-day activity and mappers are grouped into teams and each team will be given a Global Positioning System (GPS) to map their respective areas in the city. Each team would either be in vehicles, in bikes or would walk around the city.
Several groups and sectors have chipped in to sponsor the mapping event, particularly on the use of the GPS equipment. We are inviting Dabawenyos to join the mapping party, assuring that there are no registration fees to be collected.
So come and be counted!

The First Transistor
In 1947, John Bardeen, Walter Brattain and William Shockley, working at Bell Telephone Laboratories, were trying to understand the nature of the electrons at the interface between a metal and a semiconductor. They realized that by making two point contacts very close to one another, they could make a three terminal device - the first "point contact" transistor.
They quickly made a few of these transistors and connected them with some other components to make an audio amplifier. This audio amplifier was shown to chief executives at Bell Telephone Company, who were very impressed that it didn't need time to "warm up" (like the heaters in vacuum tube circuits). They immediately realized the power of this new technology.
This invention was the spark that ignited a huge research effort in solid state electronics. Bardeen and Brattain received the Nobel Prize in Physics, 1956, together with William Shockley, "for their researches on semiconductors and their discovery of the transistor effect." Shockley had developed a so-called junction transistor, which was built on thin slices of different types of semiconductor material pressed together. The junction transistor was easier to understand theoretically, and could be manufactured more reliably.

Facts Everyone Should Know About Lead
Why Lead Free?
Lead is a naturally occurring bluish-gray metal. Much of it comes from human activities including burning fossil fuels, mining, and manufacturing. Lead is dangerous because it disrupts the functioning of almost every brain neurotransmitter. Since the body mistakes lead for calcium, it interferes with nerve impulse transmission, heart activity and blood clotting. It has therefore been associated with diseases that affect the cardiovascular, respiratory, reproductive, and nervous systems. A person may experience the following effects depending on the amount of exposure:
Acute Exposure: Headache, nausea, vomiting, abdominal spasms, fatigue, sleep disturbances, weight loss, anemia, kidney damage, and pain in arms, legs, and joints
Chronic Exposure: Impaired functions of the nervous system, kidney and brain damage, and slow mental development in children
You can protect yourself, your family, your home, and your world from the toxic effects of lead. Use only Lead-Free products.

Choose The Best Video Game
Video games packs with so much fun but care must be given because it can consume all of our precious time. Video games today, bring us to the next level of entertainment because of the development new technology such as portability, wireless controls, high definition video and packed with high capacity hard drives. The three major manufacturers of video games are Microsoft, Sony and Nintendo.
The Xbox 360 is the product of Microsoft, Playstation 3 (PSP 3) for Sony and Wii for Nintendo. The graphics quality and realism for Xbox 360 and PSP 3 are equally excellent but Xbox has larger library of games with removable hard drive. The PSP 3 can play Blu-ray disk. It includes Wi-Fi with Internet capabilities having a built-in browser. Nintendo chose not to compete with the two top companies, instead, they focus on the Wii Remote which a unique motion-sensitive controller that gets players off the couch, waving the controller around in the air.

Whatch Your Favorite Shows
Direct TV is fast emerging satellite television system. Why is it that this new system is advantageous compared to cable television? Direct TV is a digital transmission system where you have a lot of choices of movies, music, sports and internationals channels while in a cable system, the channels are limited to what they offer.
Since Direct TV programming is digital in nature, all shows are 100% digital quality picture and sound. One advantage of digital programming is that there is a feature in their system where you can digitally record videos. So no worry if you miss the favorite movies or programs, the recording is one touch of a button.
Direct Sat TV has a variety of packages that will serve the needs of its costumers for the right price.

Can You Cheat On Someone You Truly Love?
When we are in-love, we always say to our partner the magic word, "I LOVE YOU". When we say it, do we really mean it? How do we know that our partner is honest to what he/she said?
A friend of mine is a victim of dishonesty. While he was away, his girlfriend cheated on him. The girl always denied that she is faithful to him and loved him so much that she is willing to sacrifice her life to him because the other guy is just her friend. A few months later, the girl's greatest secret was unlocked and my friend was deeply hurt and this are his words, "Your love is a beautiful lie."
Is it really love that we felt for our partners if we cheat on them? If we can't be honest, if we can't stand for the things we say, let us not say the magic word because our partners will be hurt.
For you, can you cheat on someone you truly love?
