How to turn your breadboard rat’s nest into a badass circuit – PCB manufacturing tips

Printed circuit board (PCB) manufacturing is a black art among the DIY community.  If you’re putting together a prototype circuit, the process is very well established: get an Arduino or your microcontroller of choice, pick out some components, get a breadboard and wires, and then string everything together.  Easy, low cost, and accessible.

However, what if your project becomes more complex?  You can extend breadboard or perf-board work to a point, but the likelihood of making an error grows exponentially with project complexity.  Nobody wants to end up with a circuit that looks like this:

Now THIS is a rats nest of wires.
