Stage 1

Measure the perf board and measure the wires from hole to hole, I drew a diagram or this on illustrator or can be done using frtizing, I found the diagram on illustrator helped because i could just check the grid reference of the holes when I was soldering. I have read that some people map this out on graph paper so whatever you find easiest. (I didn't have graph paper to hand)

Stage 2

Once you have mapped out the perfboard solder the first of the wires to the board, making sure you do this before adding the components and component connections (these need to be done last)
