5V voltage regulator using 7805 | Complete Process

While making circuit a power source is the essential component. Power source can be made by different circuit. Here i used the most popular integrated circuit 7805. Which is a 5v voltage regulator.

Schematic

I made this schematic in KiCAD software.

After this i made some print out. Drilled a few holes. As i do not have a laser printer i am unable to make a photoresist mask. So i use old school permanent marker for masking wire trace.

It is not the best job of solder that i have done. But it is not worst i did and definitely not the best.

I did not have paint or the PCB lacquer. But in my home i found this used nail paint. It barely works.
