I'll try to get the GB going as soon as the pulley GB is over. But we really need a bit more interest to be able to do it. The system is gonna be built using 439 SS and the price for it is just amazing.

The cats are extra but I think they are gonna be extra in the yodude one too
(who needs cats anyways
)
