Business Analysis: An Overview #66

  • Before 19th century no one systematically studied the effectiveness of the different approaches of management
  • Business Analysis – is a very recent profession. Due to the radical change in information management and communication businesses needed a new way of analysis – hence, the profession came into play
  • The profession came into existence during the information technology boom in 1980 – 1990
  • When businesses created a new profession to serve the purpose that a System Analyst does in IT – the profession became the business analyst
  • Though, nothing can guarantee success, understanding the core concepts of the Business Analysis area will help you to work more effectively as a business analyst
  • Six knowledge areas of Business Analysis:
    1. Enterprise Analysis
    2. Requirements Planning and Management
    3. Requirements Elicitation
    4. Requirements Analysis and Documentation
    5. Requirements Communication
    6. Solution Assessment and Validation
  • Responsibilities of a Business Analyst
    1. Identify Business Problems and Opportunities
    2. Eliciting, Analyzing, Communicating, and validating requirements for changes to business processes
    3. Recommending solutions to help businesses achieve their goals
  • The role of the project managers and business analysts may seem similar. Really, there are some overlapping areas such as, identifying goals and requirements, risk analysis, and finding strategies for project success. However, the project manager is responsible for the timely completion of the project within the budget. The business analyst ensures that the project is completed correctly with the defined requirements.

How to make a car cell phone charger (circuit level). #68

How to make a car cell phone charger (circuit level).Just the pretty basic idea

You will need a power source: You can use

  • Car 12V power supply
  • car cigarette lighter may be
  • Find electrical wiring of the car

Then find/buy/make a connector to the power source and/or use wires/cables to connect to them as applicable

Now check the charger port of the cell phone that you are usingIs it circular? or flat with some pins/small iron bars. Check the specification of that particular model of the cell phone. Find out the pins that are used for battery charging. Usually the cell phone specifications will have that. Try to find out which pin takes how much volt? If it’s a circular port, you also need to find out how much volt/amp to pass and to where.

Now find a chip that can convert the 12v car volt to the required volts (as required by cell phone ports/pins). Or make such circuit using multiple chips. You may need to connect several such chips/resistors in serial to get the desired voltage levels. Use resistors if required.

Now, create the connecting wire to connect voltage source to the cell phone port. You may need to use multiple wires if the cell phone has multiple points to feed voltage to.

oh yes, you gotta supply voltages from the car power source to the power sources of the chip/(s). So you need some wires/cables in that section as well. THE Circuit Part Will be in the middle with wires/cables in both directions from it

Now work on packaging: the input port (car end), the connecting wire, the output port (cell phone end).

Take professional help before trying this idea.

Read below, to get ideas on which chip to use. Also, check full specifications as provided in some of the URLs below [Reference: the Internet]

http://www.romanblack.com/smps/conv.htm+5v to +13v Converter

How about DIY?You can use either 78L05 (100mAmp), or 7805 (1Amp), or LT1804CT-5/LM1084IT-5 (5Amp). With any of those chip and couple caps, you can make your own 5V regulator for less than 5 bucks.

http://www.mp3car.com/power-supplies/24383-12v-to-5v-step-down.html

http://www.supplyframe.com/partsearchservlet/partnerWormhole.action?id=981155&partnerName=DSA

I’m planning on using LT1084CT-5 because it’s a fixed voltage and has enough head room for two 4-port usb hubs. Thing is, someone mentioned that you have to have other components, is that true? or can I just connect three wires to it and call it a day?

Forget using a 7805 regulator unless you have one on hand, and have room for a fat heatsink. Go to a “dollar store”, thrift store, or flea market, and buy an obsolete car charger for a cellular phone. These typically contain an a small circuit consisting of about a dozen components, primarily a MC34063 switchmode-regulator chip (an 8-pin integrated circuit) that is much more efficient than a 7805 (and therefore waste less energy as heat). If you take it out of the case (insulate it with a piece of heatshring or bicycle tube), a typical 12->5v phone charger circuit is no larger than a 9v battery and can handle about 1 ampere of current. You can’t build one for the price you’ll pay at a junk store. You can change the output voltage to anywhere from 12v to 1v by changing one of the resistors (google mc34063 datasheet for details).
