I have created a HowTo at Instrucatbles on how to make “Double Sided PCBs” at home.
If you’re planning on creating your own controller its a worthwild skill to have! Without the ability to create my own boards at home whenever I like, this project would have ended up costing a hell of a lot more money, time and stress.

It costs mere pounds to make a handful of boards yourself and there’s a lot more room for experimentation! If something goes wrong and you’ve connected the an output to the wrong input, you can just re-design the diagram and start again that night.
