    But with this you should at least get the gist of it.

    OK I finally got it to work... kinda...

    Kurochou - if I'm not mistaken and reading the schematic correctly and understanding what you wrote earlier about how transistors work, this wiring diagram eliminates the need for a relay.

    But I'm not sure - does it address the issue of making sure the circuit is off when the board is off? I may have wired it wrong... (heck I'm still trying to wrap my brain around your lecture)
    I *am* however getting bright clash on flash like I did with the relay method, but again, part of the point was to have it simple so that the accent LED would be off when the board was off without the need for another switch. (hold on - my brain is slowly working towards a solution here)...

    God this was so much easier to understand in High School... <sigh>...

    double Edit: The NPN actually seems to be controlling the flash and at the same time reversing the signal (at least as far as I can tell).
    The PNP at the bottom doesn't seem to be needed... ???
