Haha no worries :) Considering that I am not a native English speaker, I'll have to take that as a compliment :). Putting modesty aside, I have to admit that I lived in California a few years back and that's why I happen to have slightly better English than most French speakers you'll encounter :) I try my best to keep speaking, but especially writing and spelling correctly, otherwise you can loose your English in no time.

That aside, I still have a question =) Can someone look at the enable relay circuit I have in the diagram ? I had a discussion with Graeme and I am not sure whether the ENABLE is setup correctly. Should it be a NC or NO relay ? I'm asking because it is confused whether the ENABLE actually works backwards than what its name says. It seems to me that logically, the drivers should only be working when the "enable" gets powered up (5V) and disabled when it has no signal on the line (0V) ?
