So did you have that board fabricated? If so, what board shop did you use?
I used Seeedstudio. They're fast, I submit the design files and have the PCB's in my hand in as little as 9 days. Here's a link- http://www.seeedstudio.com/depot/services-c-185.html
@02Surplus: Awesome! So basically you stripped the components off the Arduino board and made your own PCB? Is the off the shelf board not flexible enough? I am planning to build a controller similar to yours but am torn between using a microcontroller or a cpld board. CPLD just because I can add to the circuit if I decide to control other stuff like pumps and auto top off systems. May be interface it with a PC too! who knows!
Wow, according to their website $10 for Ten 5cmx5cm boards! What was the total cost of your board order?
@o2surplus: Pretty awesome. Just been reading your posts and am very interested.
In your honest opinion do you think it is something that a regular person (ie pretty competent at DIY) could attempt
The only hitch is I have never tackled anything like this before but willing to give it a go.
