Start with the schematic from my last post:
Design the circuit layout. If I was going to make a PCB this would be quite straight forward as I created the schematic in EAGLE; I would just select 'File > Switch to board', position the components and hit autoroute. However, I am going to be using vero / strip board so I have to do the layout myself. I did it on paper, but I have re-done it using DIY Layout Creator
Cut out the board and start soldering in the components:
Once all the components are soldered in we can start placing the jumper wires:
The last thing to do is to attach the cable we will use to attach it to the arduino. I had a good length of 5 core cable from a Nintendo Gamecube controller which is perfect for this task, I just need to attach pins to the end of it so it can plug into the arduino.
Testing. This at least is simple. Just plug and play. Like windows, only this might actually work!
All I need now is a stand for it. Thankfully I have an old library card that will suffice just nicley. So two minutes work with a craft knife, a ruler and a screw driver and we have the finished product!
I know the stand looks a bit crude, but it does the job nicely.
