While using wordpress for blogging, you may have to add externel links. For example if you need a link to your flickr page, you cannot add it from the wordpress menu. I think adding external links in K2 theme of wordpress is a little bit different.
In some of the forums they will ask you to edit header.php in themes/k2/ . Or some may ask you to add an plugin. But I don’t love adding plugins too much. And I think adding external links in K2 theme of wordpress is not very hard.
Do you see the new link as the first ? Just try to add the same line in other places and have your links placed as you wish….
I am back with the revised version of GNUdino-AVR. This is actually one of the projects in FOSSTRONICS . Also you can understand more about GNUdino-AVR from my previous blog post.
The last version that I had designed contains several errors. But first I didn’t realize those mistakes. But after posting to gEDA-User mailing list I got some suggestions. These were some of the reply for the mail that I had received from gEDA-User mailing list when I had asked for error check.
Special thanks to gEDA-User mailing list members for pointing out the errors.
This version has a few of improvements.
1) Components are on Component side (Last time by mistake I had placed them on the solder side).
2) Polygons (There was no polygons in the last version).
3) Numbering of components were removed (Last time all resistors were ‘R1′ )
This is the source file GNUdino-AVR-0.2.pcb
This time also I have posted for a error check to the gEDA-User mailing list.
If you can please check the file GNUdino-AVR-0.2.pcb for errors. Also comment out those errors. It would be a great thanks if you can do that…
These are the files that I have used for tracing from the Eagle layout. The tracing process had been explained in the previous blog post. You don’t have to check these files for errors. These files have been placed for educational purpose i.e those who want to learn PCB track tracing in PCB.
For latest versions of GNUdino which are designed from me can be found from http://jeffrey.co.in/gnudino/
Arduino is one of the coolest board to start learning microcontroller programming. You can get a whole lot of documents from the internet. It’s an Open Hardware project. So that you are free to distribute it, copy it, modify it…. like a free software. Open hardware is a latest trend in the electronics field.
One of the problems of Arduino was that, it’s designs were done using a proprietry software named Eagle. Although free version of eagle is available from the net, it is not a free software. Also the free version of eagle has a limitation that we cannot design large boards.
So I thought of redesigning the Arduino Single-Sided Serial Board (version 3) board using free software gEDA (GNU Electronic Design and Automation) tool. These are the design files of the board.

I have designed this board by tracing the pcb layout of arduino which was designed using eagle. A small tutorial of tracing pcb’s by DJ Delorie is shown here .
Place these two files in a folder. Now in the terminal run the command
pcb –bg-image 125_90.ppm ard.pcb
You can see the pcb tracks over the arduino pcb design which was done using eagle. The pcb tracks were drawn on the component side. While loading the file, PCB will be showing the component side. So you will be seeing the tracks not sitting on the background image. To switch to the solder side press the “TAB” button. Now you will see the track alligned.
Please check the files for any mistakes. If there is any, please comment it.
If you have any comments please do it…
