I certainly hope so - I've got to make an acuqisition of some technic
bricks, gears, and axles first though. I only have a fairly limited supply
atm available from 8485/8479, the latter which had a motor which went dead,
and so got turned into parts fodder for this project. The Control Center is
an excellent permanent power source, as I don't need to worry about
batteries for the project.

That should be possible, although what I really want to do is eliminate the
40t gear, so as to be able to use it elsewhere. I will see what I can do
about bringing the rotation speed up a bit, although it's more a problem of
getting the basketballs to pop out than anything else.

Yep - one acuqisition I do want to make is a Mindstorms kit, although on a
limited budget such as mine I don't see it happening 'soon' unless sales in
my store happen, or I come into some money. *grins*
