Printed Circuit Boards will make your circuits more compact, reliable and durable. The process is to create a board that is an insulator with paths of copper conductor that are cut into a pattern that makes up your circuit. One way to do this is to start with a board that is fully coated with copper conductor and cut away the copper to produce a circuit pattern with what remains.
It is possible for one to produce high qulaity PCBs using the Bantam tools CNC machines. This lesson will begin as a collection of links to software tools and website tutorials to get you started.
Designing your Circuit
We need a CAD based tool to develop our circuit. The circuit begins as a collection of components wired together or on a breadboard. The software produces the schematic diagram and a layout of your circuit pattern, You can adjust and optimize the pattern to your needs and see it on the screen before you produce it. The software then produces a file that is used by the CNC machine to cut the pattern.
CAD tools for Circuits
A somewhat simpler tool is Fritzing. Fritzing is a tool for developing your circuits and can do everything we need for simple circuits. It is kind of shareware where you pay just $10 to use it forever. Rolling robots has a paid account for this ask DK for the password to download.
Fritzing will produce a Gerber file but the CNC needs g-code so there are tools to convert. One free one is FlatCAM.
