In this article we will discuss how can you make PCBs using Eagle Layout Editor 5.6 Freeware (PCB design). First of all Open Eagle , under Projects right click and then left click to New Project . Give a name to the new Project , for example ‘ example’ and then click Enter . Right click the example , you created, and select New and then board. We will design a simple led chaser using PIC16F84a micro-controller. Add the component needed for this circuit by clicking on ‘ADD’ icon from tool panel in left. After arranging the components we get the figure like this: You can also assign the name to the component by selecting ‘name’ icon and then chose the component which is to be named. Now select the ‘wire’ icon, and the color for wire (normally I chose red). After tracing select the ‘polygon’ icon and draw a polygon (across the whole circuit), after doing this click on ‘Ratsnest’ and you will get this: Now give the name to the polygon (for example Vcc,Vss et...

Often we do not have the opportunity or the money to keep our hobby, sometimes we lack tools, but always there is a knack for everything, is what we see here in this article was originally published at indestructible. He teaches you how to make your own breadboard using scrap old computers, in fact it uses sockets IDE cable. The breadboard makes life easier for those who like to create electronic circuits, and can only plug components without using solder.
