Computer Speed Slow Down

If you use an Apple computer, your computer system will use a File Extension 09 on your computer registry system. This file often affects the speed of your computer work. Because if one of your system file broken this may still work but the computer then run slowly. Other problem can be by viruses attack, your computer should install cleaner and antivirus. The second tips in order not easy to attack, you must create window password to open your windows.

But longer you use your computer then slower it runs and the more it crashes? Often this phenomenon is caused by problems in the registry that accrue over time. Installing and uninstalling programs leave behind fragments — stray files, orphaned startup tasks, corrupted drivers. Over time the registry starts to get bogged down and conflicts emerge. One reason that can cause this slow motion of your computer work, is because of your File Extension 09 broken.



Overcoming this problem it should check the system registry file on your computer. Then you can conducts deep scans of your registry to check for errors and conflicts, then repairs and optimize the registry to peak performance and stability. Periodic scans will keep your registry "clean" and will greatly enhance your system’s performance and stability. You’ll see immediate increases in speed and decreases in system conflicts. You can try to download this File Extension 09 to repair your computer system file.

Basic Electric

Electron moving
Electron and Nucleus Atom contains skin and nucleus. Skin of atom contains number electrons and has negative charge. The knowledge about the atom on physics is the basic electric knowledge. These electron moves around the nucleus on rounder orbit shape. This order of every orbit only can have a certain electron with certain rule, that every orbit can contain maximum electron 2 n2 (n = number of orbit that is counted from the nearest to the nucleus). So the first orbit can only have 2 electrons, the second orbit can have maximum 8 electrons, and so on.




Nucleus or center of atom have positive charge; on the nucleus have proton and neutron. This proton and neutron can't move to other atom. As example for atom hydrogen have one electron, one proton and one proton. As electron theory proton have positive pole, neutron don't have charge or neutral. Between proton and neutron is bound tightly. Actually the condition on the atom is look like the formation of solar system in the universe. Electron always circle atomic nucleus like planets encircle the sun. Bigger rotation circle also bigger energy. The electron circle nucleus 300.000.000 meter/second, this is amazing speed for electron that is very small. Although an atom can own a lot of electron but in rotation electrons encircle the atomic nucleus never colliding each other, because every electron rotate in their path. Free Electron On the atom sometimes have free electrons that are located in the outer of the electron circle path and have farthest distance from the nucleus.

This electron can move to other couple atom and become the group of this atom to circle other nucleus atom. The properties of this electron called free electron. Free electron usually available on the metal material; such as iron, copper, silver, gold etc. Non metal material such as glass, ebonite, wood, mica, etc, has no free electron. On the electric matter this free electron has an important role in conducting electric current.

Make Phone Cell Battery Charger

Electric Circuit for Phone Cell Battery Charger


For the time being we all use phone that always need battery charger after use for certain time. Actually the development of technology already made a better battery that can keep power longer time, but phone cell activity like many application are running on and for this also much more consume power. Battery charger also sold in cellular shop cheap because this product already mass produce by big company like from China.

By the way we can make phone cell charger by ourselves if we want to do, or want to repair your battery charger because can’t stand for longer time. The basic theory of electric can convert from AC to DC electric current. We also know that the frequency of household normally 60 Hz. This conversion can draw as follows:


Electric Wave from AC to DC

Those alternating current then connected to electric transformer to reduce the voltage and several diode to make electric current become direct current. For phone cell usually use 9 volt out put from transformer and we set after flow out from electric converter become 5 volt DC Current.

And then after through electric circuit that arrange using four Diode the electric frequency become like the below diagram.

Complete Diagram of AC/DC converter

The above circuit need other part called as Capacitor that keep electric current slow up and slow down when there is electric shock in or out. This capacitor can make the profile of electric current more even not like wave up and down. Using capacitor can make the DC current more stable not up and down and no electric shock when the plug is cut off from electric source, and after install in PCB will look like as below.

Make Electric Circuit On PCB Coppercoat plate

Prepare chemicals and tools need for make electric circuit over coppercoat plate


Printed Circuit Board or PCB is a plastic sheet that coated with copper which is copper have very good electric conductivity. Over this PCB we create a circuit that connect of every legs of electric component in order can flow electric current through circuit board. Through PCB we can connected each component that is needed to connect and release an electric current as we propose.

To make electric circuit over PCB we need the following parts:

  1. Blank PCB single layer
  2. Ferro-chloride Powder ( the solution of this powder is functioned to dilute copper that is stick on PCB)
  3. Iron
  4. Photo paper
  5. Wash basin
  6. Nippers
  7. Mini Drill
After all the above material provide then we ready to the next step.

Make Electric Circuit Layout On PCB Copperplate


To create simple layout of electric circuit on PCB we can download from the computer of many electric circuit for an purpose. After we got the circuit layout then we can print on photo paper or on calendar paper. To print this we better use laser printer to make a smooth line. To print this layout we can just rent on photo copy rental to make cheap. The sample of printing result as on the below picture.

Electric Circuit Sampel

Other Electric Circuit
  1. Prepare blank PCB and clean the surface with alcohol or other cleaning solution like thinner and let it dry.
  2. Stick the printed paper with drawing face to the copperplate layer of PCB.
  3. Use adhesive tape to make this paper don’t move from the blank PCB
  4. Cover it again with paper like newspaper
  5. Ironing the newspaper for about 3 minutes, set the thermostat of ironing in about ¼ of the total hot setting in order not too hot. If the iron too hot the drawing can be blurred on the PCB and make bad electric circuit.
  6. Dipped into the hot water for about 2 minutes to open paper that stick to the PCB easily. From this process you will get electric circuit drawing over the PCB, clean all paper that still stick on the PCB carefully. If the drawing don’t perfectly or there is a disconnected line, you can repair this line using permanent ink.
  7. Let the PCB dry
  8. Use wash basin from plastic or ceramic and put in them Ferro Chloride solution. Basin wide must enough to put in the PCB in the bath. To make the solution of Ferro Chloride put hot water one liter and mixed with 2 food spoon of Ferro Chloride powder. Stir this mixing until all Ferro Chloride diluted.
  9. Put into this solution PCB with electric circuit and shake the PCB until the rest of copper but the copper with electric circuit line is not dilute.
  10. After the rest of coppercoat is finished wash with water to clean the solution.
  11. Clean the PCB plate with sand paper to make ink that stick to the board is removed.
  12. Clean again with water and let it dry.
  13. Drill the board for each electric component which will put electric components.
  14. Done
