Well I've gone back to designing my LED controller board... got the circuit done and working and all - it's got to as it's the same one I've had before. It's just a case of making it fit in a case... and nicely talk to the other boards... oh and all the compents fit on the board nicely... which is the problem, because I'm giong to forget something, and when you've got 5 identical boards at 80 quid each made up, it could be quite expensive!
Today I've managed to find a few fatal flaws in the design, which is great, but it'll always be nagging me until the boards arrive that I've missed something - when the boards arrive - I'll know for certain that I've missed something :D
