Thank you so much bibin.
Much appreciated.

I made 3 layers ( top, bottom, drill hole ref ) from the download of that site, and gave it to a man who makes PCBs. Probably he is going to charge me a fortune but since this Project is well tested by our respected fellow members like Pra, Sudhir and many others, I decided to take the risk.
I might get the PCB the day after tomorrow if everything goes well.
If not, I definitely will take resort to your kind concern.

Thanks a lot, really, Bibin,
You are welcome CSOM.

Could you name a magazine that can be used for this purpose?

Thank you.
Sorry for replying late...I use my office laser printer for this purpose ..for home purpose you can use hp1007.
2. Magazines paper with medium thickness (less than copier paper) and glossy finish (means entire page is covered with printed material/ink) are best for this purpose.i.e the week,India today etc.
thanks.

I used Gimp to adjust the top layer coordination with the copper side but couldn't be able to get the correct size at first.
I somehow managed that finally.
HI,
I dont print component reference on top layer on pcb...I place the component just by comparing with given photo.
thanks

Thank you so much Sudhir. I will go for hp1007 very soon.

Now the concept of using magazine paper is crystal clear to me from the Indian Perspective. I was kinda lost earlier.

Thank you

Thank you Sudhir and Bibin.
Your photos will definitely help me as a good reference.


I've finished the PCB just now with the help of a friend.
Bottom layer is okay.
The drill reference points I made are okay too.
But the top layer is blurry as expected

Here is the Photo of 3 layers of the PCB, an example in case anyone makes the board with silk screen printing.

1. Bottom copper layer: Provided by the Author in the download.

2. Top component Layer: Provided by the author in the download and given only as a reference by the author to DIY-ers.
I resized, edited and aligned to fit the size of the PCB in my personal hobby project.

3. Drill hole reference Layer: I made it following the original author's design as I wanted to give the PCB a professional look
This layer can safely be ignored as redundant.

Thank you Som. How much did they charged for making the PCB?

Have you completed populating the PCB with all the components? Which amps are you going to use with this?

thanks,
Bibin
