yep, bicores are beautifull ....
but oke, I actually don't know what a photopopper is, except for that is
has two motors. If I understand it right you want to change the cicuit so
that it uses one motor instead and uses the connections which were used for
the originally two motors to forward and reverse this one motor, am I right?
well, why don't you put a H-bridge in place of the two motors, I mean:
connect the wires, which were connected to the two motors to the inputs of
the H-bridge. Then you have two wires left (the ones which were to be
connected to the other sides of the two motors), which were hopefully (but
then again, I don't know the circuit of the photopopper) Vcc or 0V, since
then you can just leave those (read: connect them to the Vcc or 0V of the
H-bridge)
Well, this probably doesn't work (for all sorts of solar-specific reasons),
but maybe it makes you get an idea or so ...

You can connect tacticle sensors to a bicore as wel.
