    This is on the output of the 7805, right? The cap is the reservoir the driver will lunch off of until the 7805 can refill it.
    A 470uF 6.3v cap is about 12mm tall and 7mm dia. That's not that big.
    But if it is, you can spend a few more pennies and buy a tantalum cap. Much smaller, about the size of an M&M (without the peanut).
    If that's still a problem, use a smaller value cap if you have to.

    I'll check again. Radioshack seemed to have some tantalum caps that might work. I really cannot wait to hook this all together and see if it works.

    Good catch. "If" isn't the operative word. I'm certain that any problems will not be on the hardware end, provided I don't cross my wires. Scoping the outputs should be pretty exciting too.
