PCB design of versatile audible continuity tester

PCB design can be fabricated by etching on the copper clad board easily

PCB design can be first laser printed on art or photo paper

Transfer the design from paper to copper clad board by heat process

Copper clad board then can be etched with Ferric chloride solution

Appropriate holes can be drilled

Circuit elements can be easily and neatly soldered and assembled

PCB component layout view is shown below:

Full PCB view is given below 

The PCB can be easily fabricated and put to use. The working details are widely discussed in the previous post.
