Thats a nicely presented well thought out project.
You show far more bravery than me... you used those infernal surface mount thinggies... I turn into a snivelling whimp every time I have to work with them.
I also like to use single side where I can, except for power boards in pwm stuff.
There is only one thing more than surface mount stuff that scares me..... and thats when they are potted. ( like the Polaris ATV CDI unit I had to fix the other night).
Very nice project

Edit:
Like this:
An hour to dig the gunk out, and 10 mins to fix the thing.
