DIY PCB
Making electronics projects and finally watching them work is very interesting. But assembling components on a general purpose PCB is very cumbersome. It’s is a very time consuming task and sometimes the circuit mess up so much that it becomes irritating to work. It will be a great if one can fabricate PCB (Printed Circuit Board) for electronics projects at home. It is an interesting task for any electronics hobbyist. It saves time to complete a project and also increases the reliability of project. Continue reading “DIY PCB”
