Creating my own printed circuit boards is probably my favorite skill in electronics.
When I learned that it was easy AND that it didn't have to cost a lot of money - I was in electronics-heaven.
Because when you know how to design your own printed circuit boards - or PCBs - you can:
- Use as many components as you want
- Easily add modern technology to your gadets (WiFi, Bluetooth, USB, ++)
- Have a large amount of wires without loosing control
These are things you just won't get when creating circuits on prototyping boards.
