I didn't take any many pictures during construction so I'll just piece together the "need to know" stuff the best I can.....

If you don't have the time or energy to etch you own board you can easily do this with a pre-drilled board from radioshack or just use a bread-board to hold everything together, there is no wrong or right way... just what works best for you.

I won't do a "How to etch a circuit board" tutorial in this instructable since I already did one in my last instructable on how to make a guitar Distortion pedal which you can read here Dead Rat Pedal .

I mocked up the circuit board design in Adobe Illustrator based on the data sheets of the components, it isn't perfect but it works for my purpose. (See the PDF for the actually layout).

In the future I will do a revision of this board since I wasn't planning to use a LCD panel originally. I had to make some extra solder connections to the Ground and 5 Volt lines for the lcd panel so it is a bit messy.

This is really as simple as following the pin-out on the last step and connecting everything to their correct place... nothing too complicated that I remember.(Use the pictures as reference and they will guide you well!!)

The only difficult part I ran into was soldering the tiny pins on the ethernet jack for the connection of the LCD panel. You don't have to go the Cat5 cable route but it just makes it easier to connect and disconnect the lcd panel for future upgrades.... like for maybe a 4 line panel!!!
