So the time to make the board has come. I pick my etching solution, an old Bakelite PCB board, clothing iron and laser printed circuit. I transferred the image to the copper, placed the board on the etch solution and waited.... and waited... and waited... At the end of the day a had nothing etched, with lots of copper on the board. I then decided to keep the board over night in the solution. Really bad idea! Next day I had almost nothing on the board, no copper but also no toner on most of the circuit. All I had left was a sad looking board pleading me to end it's misery. And so I did it.

As I didn't want to fine tune the etch solution (too strong?, to weak? at this point i don't even know...) I chose to use a perfboard for the main board, following the schematic for the board.

The rest of the assembly was uneventful, just solder the wires and the components to the board. In the end I had this:
