Chandni Chowk of Delhi

Posted in General on June 27th, 2009 by Ravi

No where else in the world happens so much business I guess. Chandni Chowk is an area in Old Delhi. It is a filthy place which American and European journalists and documentary makers would love to portray as the image of India, but the amount of business that happens there and the variety of products available there really overwhelm me.

With the little bit of electronics education that I have got in the past, right now I happen to be an electronics hobbyist and I make amplifiers for the audio frequencies. I made my own D2A convertor for my computer, which is better than what the motherboard has got to offer, and I have designed my own transistor based power amplifier to drive the set of speakers that I have got. And Chandni Chowk is the best place in the country that I can think of to get all these things for the cheapest rates in the world. I can make an amplifier for about Rs 10000, with the same output and quality of Yamaha amplifiers, if not Bosch, which would be available for around a lac.

Chandni Chowk is a very huge market place. It has got everything. Electrical fittings, bulbs of a huge variety, plumbing accessories, glass tile,, electronics and great food.

Graphics Accelleration Card

Posted in General on June 16th, 2008 by Ravi

A graphics accelleration card or a video card is a card that is fitted onto the motherboard of your pc, which would deliver greater video performance of your computer than what you would have built into the motherboard. Usually, video cards are used for gaming, and for high graphics rendering, and while working on animation like Maya, 3D studio Max etc.

The video card provides better processing of the video signals, and provides you with a crystal clear output of the ever changing images in high definition gaming, which would provide an ultra smooth output on your screens.

Putting your PC together yourself

Posted in General on May 25th, 2008 by Ravi

Loads of companies assemble the PCs themselves, lock the box and ship it to you. You never know whats inside, if its screwed properly, or has rusted due to the humidity in your place. And, branded PCs are always expensive. It is a good idea to get the components that make a PC yourself and put them together. It is no big deal. The PC comes with about 11 components, and all you need to do is to plug them all to the motherboard, and when you switch it on, you could install the Operating System, either Windows or Linux, and start using your PC.

But if you dont know how to do it, where and how would you buy the components? How would you find out the list of stuff that you need to go for? I can ofcourse give you a list of things that you need to by, but I canot tell you the best product thats available in your local market that comes with the best price as well. In India, Mercury is the cheapest and best motherboard, but if I have the budget, I would definitely go for original Intel or Asus only. So, it would be a better idea if you could get your computer parts in a kit with which you could build a PC with just a screw driver. You will find it amusing when you see what you ca build, and this way, you wil find that you would have saved a lot of money from a Branded PC.

How to assemble a PC? Put your PC together yourself.

Posted in General on December 8th, 2007 by Ravi

Do you know how to screw? Do you like screwing? Do you think screwing is fun? What about plugging then? You like that too? Then you should assemble a PC. Putting a PC together is always fun.

Requirements :

1. Processor

2. Motherboard

3. CPU Cabinet with SMPS

4. Kyeboard and Mouse

5. Hard Disk

6. CD DVD Drive if required.

7. Monitor.

8. RAM

Optional components :

1. Sound Card

2. AGB card

3. USB Expansion card

4. any other PCI card as desired.

Tools Required :

1. Screwdriver.

The best thing about assembling a PC is that all you need to get it up and running is only a screw driver. This technology is called screwdriver technology, and is powerful enough to make a novice call himself a computer engineer.

So. Let me come to the steps. You will need a workbench. But I prefer the floor. Buy all the above components as per your requirement, bring it home and spread it on the floor. You might need a small cup in which you can put all the screws so that they wont be rolling on the floor to prick on someones legs later.

1. If its a decent cabinet that you have bought, the insides should be completely of conductive metal, so that any earth current from any component flows directly thru and gets grounded. You will find a removable plate inside the cabinet. Remove it. and place it on the floor. Copper or plastic raisers will be supplied with the motherboard or the cabinet. Place them in the appropriate holes on the plate so that it matches the holes on the motherboard. Keep the plate aside.

2. Take out the motherboard, place in on your lap with a pillow in between. Open the processor case, and take out the processor. Open the lock on the processor socket, place the processor in it matching the arrow on the processor and the socket, and close the lock on the slot. Take out the processor heatsink, remove the sticker from the heatsink-paste layer, place it appropriately over the processor and lock it. The heatsink-fan will have a wire which needs to be connected to its appropriate socket on the motherboard.

3. Fix the RAM chips into the RAM slots on the motherboard.

4.Plug the IDE and SATA cables to the appropriate sockets.

5. Now, place the motherboard over the meta plate which was removed from the cabinet earlier, and align the holes on the motherboard to the raisers that were placed on the plate. Make sure that none of the contacts or soldered points on the rear of the motherboard touch the metal plate, as if they do, it means Short Circuti, and it will make a very logn circuit for you to get all the damaged products replaced and start assembling again. You will need to just push to lock the boards on plastic raisers, and will need to screw the boards to copper raisers.

6. Place the hard disk and CD Drive to the appropriate compartments in the cabinet and screw them :D .

7. Screw the plate to the cabinet.

8. Plug the Processor power supply that comes out from the SMPS to the appropriate socket in the motherboard. This is a 3.7 volt supply line. It is usually a cable that comes with a square plug. You can read the sticket on the SMPS to find out which plug is what.

9. Connect the motherboard supply line to the appropriate socket. This us usually a big one, with multiple colors of wires in it.

10. You will find Rectangular plugs with 4 wires in it, 2 black ones in the middle, and red and yellow on the either side. Usually you will find 2 pairs of these, good enough to connect 4 IDE drives. If you have a SATA drive, you will get an adapter too with it. Or if you managed to get an ultra modern SMPS, you will find the plug for SATA drives too.

11. Then you will need to connect the on/off switch, reset button, and the LED indicators to the motherboard. Its not a tough job, read the mohterboard manual to find where the sockets for these are.

12, Check the motherboard manual and find out if there are any special jumber settings to be made. If anything is mentioned, follow that.

13. Plug the IDE and SATA cables attached to the motherboard to the respective drives.

14. Plugin the PCI cards if any and screw them.

15. Check all screws if they are tightly screwed, and check all plugs. Double check the rear of the motherboard and make sure that none of the contacts are touching the plate.

16. Close the cabinet and keep it aside.

17, A monitor usually comes with a base whih would need attaching. Do it as per the instruction manual, and place it on the table.

18. Place the CPU in position and plug the mains cables to it, as well as the monitors.

19. Attach keyboard and mouse to the CPU.

Wa La. your computer is ready to use.
