John, (and anyone else building the controller)
Don't forget to lay down the 100uF electrolytic caps under the ST board! The leads need a 90 degree bend.
You will need to be extra careful to mind the polarity and the direction of the lead bend.
The photos show this and the assembly hints do as well, but I forgot this. (it was late, yeah that's a good excuse)
I had to make a run to the local electronics store and get new caps.
In my opinion, they should have made the silkscreen symbol show a rectangle with the outline of where the cap should go.
