Final Project

2008-04-18T09:17:00.003-04:30

Components:
2 resistors of 1K
1 pot of 100k
1 capacitor of 47nF
1 capacitor of 0.01 uF
1 Led
Sourse of 5 volts
1 Protoboard
Cables

First we conect the resistors, to the pines , 1k to pin 6, and this one conected to pin 7, remember that pin 2 and pin 6 are conected together, the capacitors are conected to pin 6 and pin 5, both capacitors are conected to ground, finally we conect the pot with the other resistor of 1k, and this pote goes to the sourse of 5 volts, pin 4 and pin 8 are conected too, the out we can see it with the led in pin 3,any doubt see the diagram of the circuit, finally we connect the source of 5 volts

As we see led goes on and off, that’s because of the frecuency, if we move the pot, we can increase the frecuency faster o slower. This circuit can be used in many others circuits to give a needed signal.

Job interviewing never seems to get any easier - even when you have gone on more interviews than you can count. You are meeting new people, selling yourself and your skills, and often getting the third degree about what you know or don't know. Here are job interview tips to help prepare you to interview effectively. Proper preparation which help alleviate some of the stress involved in job interviews.
Job Interview Tips
Practice
Practice answering interview questions and practice your responses to the typical job interview questions and answers most employers ask. Think of actual examples you can use to describe your skills. Providing evidence of your successes is a great way to promote your candidacy.
Prepare
Know the interviewer's name and use it during the job interview. If you're not sure of the name, call and ask prior to the interview. Try to relate what you know about the company when answering questions.
Get Ready
Make sure your interview attire is neat, tidy and appropriate for the type of firm you are interviewing with. Bring a nice portfolio with copies of your resume. Include a pen and paper for note taking.
Be On time
Be on time for the interview. On time means five to ten minutes early. If need be, take some time to drive to the office ahead of time so you know exactly where you are going and how long it will take to get there.
Stay Calm
During the job interview try to relax and stay as calm possible. Take a moment to regroup. Maintain eye contact with the interviewer. Listen to the entire question before you answer and pay attention - you will be embarrassed if you forget the question!
Show What Your Know
Try to relate what you know about the company when answering questions. When discussing your career accomplishments match them to what the company is looking for.
Follow Up
Always follow-up with a thank you note reiterating your interest in the position. If you interview with multiple people send each one a thank you note.

A breadboard (solderless breadboard, plugboard) is a reusable solderless device used to build a (generally temporary) prototypeof an electronic circuit and for experimenting with circuit designs. This is in contrast to stripboard (veroboard) and similar prototyping printed circuit boards, which are used to build more permanent prototypes or one-offs, and cannot easily be reused. A variety of electronic systems may be prototyped by using breadboards, from small circuits to complete central processing units (CPUs).The term breadboard is derived from an early form of point-to-point construction; and in particular the practice of constructing simple demonstration circuits (usually using valves/tubes) on a convenient wooden base, (similar to a cutting board).

CDMA vs. GSM: Breakdown of the technologies

2008-02-11T07:34:00.000-04:30

CDMA vs. GSM

Coverage

CDMA is mostly used in America and some parts of Asia. It is currently making progress in other parts of the world, but the coverage is still limited compared to the GSM technology. Its support is currently non-existent in Europe because the European Union mandates the sole use of GSM. In North America however, CDMA generally offers a better coverage than GSM in some rural areas because it was deployed earlier. The CDMA network reaches over 270 millions users worldwide.

GSM being an international standard, it is better suited for international roaming, provided you own a quad-band cell phone (850/900/1800/1900 MHz). The GSM network is also well established in North America, but not as much as the CDMA network yet. The GSM network reaches over a billion users worldwide. CDMA is prominent in North America, but GSM reaches a lot more users worldwide (about 270 millions for CDMA and 1 billion for GSM). In the CDMA against GSM debate, GSM wins if you plan to travel to foreign countries but CDMA might have a better coverage in your area.

The best data transfer technology CDMA has to offer is the EVDO technology, allowing for a maximum download speed of about 2mb/s (about 700kbps in practice), which is similar to what a DSL line has to offer. EVDO is not available everywhere yet and requires a cell phone that is EVDO ready. GSM on the other hand offers EDGE, allowing for a maximum download speed of 384kbps (around 140kbps in practice). More technologies are being developed on top of EDGE such as HSDPA to boost the transfer rate to over 384kbps in practice. This technology requires an EDGE-ready cell phone. On a CDMA phone, your account information is programmed into your cellular phone. If you want to change your phone, you have to contact your carrier and have them reprogram your new phone. You will also need to re-enter your contact list and calendar information into your new phone. If you have a lot of contacts, your carrier might be able to help you perform this task. On a GSM phone your account information along with your contact list and other personal data are stored on a SIM card (Subscriber Identity Module) which is a small chip you can freely remove from your phone. When you get a new mobile device, you can simply insert your SIM card into it and it will work with your current account information and contact list. If you travel to another country, it might even be possible to purchase a prepaid SIM card which you can use to avoid roaming fees.

Which technology is the best for me?
When asking yourself which technology to choose between CDMA and GSM, first ask yourself the following questions:
1. Is international roaming important to me? If you travel a lot to foreign countries, you might want to opt for a GSM phone for a better coverage.
2. Am I going to transfer a lot of data using the phone? Currently, CDMA offers the best data transfer speed with its EVDO technology and is the clear winner for now. If you intend to use the phone for mobile web browsing, watching television or downloading MP3s, you might be better off with a CDMA phone.
3. Do I plan to change phone often? If you do, a GSM phone is best for you since you can swap the SIM card to a new device without having to re-enter your personal data.
Once you have established your basic needs, compare CDMA and GSM signals in your region. Also compare the carriers offering both services in your area. Talk to your friends and colleagues and ask them if they are satisfied with their cell phone carrier and how good their signal is.
Remember, when choosing between CDMA vs. GSM, preferring a network technology over another also means limiting your choice in carriers.

In this interview we make a few questions to another engineering student.. his name is Alexis Pirela and he is a electronic autmotation student.. For him electronics, it is a discipline which, studies the electrical effects of systems Composed of electronic devices (transistors, vacuums tubes, integrated circuits, etc).. he thinks you should have many requirements, you should have a good base at math, algebra, physics and others sciences; second a big knowledge of electricity and you have to enjoy your work.He enjoys the satisfaction os learn more and more as it spends the time, he like when his friends and he are studying hard too, in that moment they're stressful and sometimes they have a lot of fun. he saids that one of the most difficult things are when you trying to analyze an electronic circuits, you have to apply all laws of electricity, and then you have to discover the function of the circuit or the system, that it's too hard, a little mistake at the analyze process could be fatal
