Also known as Easily Applicable Graphics Layout Editor, EAGLE is one of the easiest schematics capture and PCB design tool available for the hobbyist and professional alike. I just wanted to give an intro to this software, as most of my circuits and pcb designs are based on this software. The best part is, there is a free version available, with limitations though, but nothing that the hobbyist will complain about.

Compared to OrCad or Protel, EAGLE will take you only 20% of the effort needed to get used to it. Its easy, straight forward, and it has an extensive library support. The best part is it is available for linux, windows and Mac OS too! The newest version available is:

EAGLE v4.16r2, and there is a beta version available for testing.

First, get EAGLE here: EAGLE V4.16R2

Then, read the manual to get accustomed to it(important!): Manual

and also the tutorial: Tutorial

After these steps, you'll be making professional looking PCBs in no time!

Gotta hit the sack now. Tomorrow i'll post some schematics, and some PCB designs of my previous works.
