“Electronic Design and Fabrication with gEDA” is my first article in LINUX For You Magazine.

This is the first time I am forgetting to blog about my article. Actually it was published in last month(NOVEMBER 2009) issue. Please read it if possible.

This article mainly gives a quick introduction about gEDA. I have also given some snaps of my designs.

This time I am with an AVR USB board. It is an tiny development board for the AT90USB162 chips.  I have actually made this board design for my friend’s main project. The design has been made using gEDA. It’s an complete open hardware project. But still the schematics are missing.

Actually I have started drawing the board layout using pcb directly instead of using gsch2pcb. I will try to upload the schematic of the board soon as possible.

Special thanks to Sreeraj and Pramode Sir. This project was completed 3 months before. But I didn’t have much time for blogging. Sorry for the late post.

Here are some of the reference links

Here is the board layout file.

Wanna get some cool training on Free software topics like How to do free software projects, Tutorials to use GIT , RPM Packing ? Then come to the online IRC summer training from Linux User Group of Durgapur (http://dgplug.org)

Entry is free. Just log on to the IRC of DGPLUG
#dgplug on irc.freenode.net

You can find more details on
http://wiki.dgplug.org/index.php/SummerTraining

All these training of this year are done by Shakthi Kannan (mbuf).

Time Table of these training are in the Summer Training page.

Just go through the class logs of the classes conducted last year and find out how effective it is.

Try to come for the IRC chat according to the time table given. I am sure it will help a lot.

Special thanks to dgplug for conducting these kind of online classes.

ATmega8 Mini Development Board

In a pursuit of fabricating pcb’s, I have won. I had designed pcb’s boards using PCB. But when I tried to fabricate the pcb in my home, I used to fail. the problem was with the Acrobat Reader  . When I take the print out on the paper for layout transfer to the board, a size change occurs to the layout. This size change make the layout completely useless. Actually it was the wrong option selected in Acrobat Reader that made the size change.Now it is OK.

This is development board designed by me for the ATmega8 microcontroller. It is a miniature ARDUINO.  You can burn your bootloader and then use with Arduino IDE or you can simply upload your hex file using DAPA programmer circuit. If anyone needs its schematic file please post an comment or I will soon upload it when I am free.

Anyway this is an open hardware project. I will try to upload the details soon. If you are in a hurry, please comment so that I can upload the details fast.

Here is the PCB layout files http://jeffrey.co.in/files/mini-AVR.pcb

These are the two snap shots of my board
