In this post, TechshopJim will show you how to etch a circuit board with about a tablespoon of ferric chloride etching solution and a 2 inch square sponge. You will be amazed as the exposed copper on the PCB disappears before your eyes, and your board is completely etched in a minute or less! Source: [...]

Having recently tested a lot this method, I’ve finally determine my “easy and cheap” way to build PCB using toner transfer method. Source: sirblog

Creating Printed Circuit Boards with a INKJET Printer When I first started looking into how to etch my own printed circuit boards, every Instructable and tutorial I found used a laser printer and ironed on the pattern in some sort of fashion. I don’t own a laser printer but I do have an inexpensive inkjet [...]

This method is generally restricted to making through-hole component PCBs. I don’t usually like to use veroboards because in my opinion, they look ugly most of the time. For more complex, professional looking boards, I normally use the toner transfer method. The good thing about this quick method is that it still looks decent on [...]

This document is not a tutorial on how to use EAGLE, although it’ll probably be somewhat useful in that role. It’s more about how to configure and customize an Eagle installation to better suit the hobbyist. Cadsoft is a German company that is a veritable mecca of software distribution enlightenment. In addition to the reasonably-priced [...]

This project shows the creation of a large array of UV LEDs. They are used to expose a presensititised blank circuit board. Another common method is to use UV Tubes. He used to make the isolation box: 54 UV leds buyed from E-bay for about 15 $ 18 resistors 68ohms, 1/4Watt for 0,60 $ 1 [...]
