I agree that the line-out problem is a pain. Here’s a diagram on my website of the simplest way to get a functional & safe output from the board. (Nothing original here, just the info from the Sparkfun schematic + VLSI appnote, turned into a pretty picture.) Sparkfun: feel free to add the image to the product description if you think it’ll help.
I’ve had major problems with long trigger cables (random false triggers & cross-talk). This happens whenever my buttons are more than about 2ft from the board. Extra pull-up resistors on each input fixes the problem, but is there some other solution I’m missing? (more info in the link above)
