Thanks

    Here's a single chip (SN754410) solution with schematic to BS2:

    Bob Blick's H-bridge is pretty hefty.
    Parallax's HB-25 is a really good investment for power.

    The 'Tilden Bridge' is for a very small motor, a battery powered toy motor. Usually 1.5 to 6.0 volts
    Only 6 transistors and 2 resistors. 2n3904 and 2n3906 transistors.
    Instead of a circuit board, you epoxy the six transitors together and then very carefully bend and twist wires according to the pictures. And finally a touch of solder on each connection. Kind of looks like a tiny six pak of flat sided beer cans.

    Google for it if that is your size.
