======Foam Rubber Machine====== Foam rubber is a fun and useful material. Having a foam rubber machine would be a great asset for HAL9K. It is a project in its own right, but can also be used for future projects. {{http://i.ehow.com/images/a06/7g/ip/diy-molding-foam-polyurethane-200X200.jpg}} =====Requisites===== *We will aim to use as few hazardous chemicals as possible, so instead of foaming agents we will use vacuum. Thus, we must either construct or aquire a vacuum pump. *The material needs to be both frozen and heated, so we must bash both an oven and a freezer. *The timings for moulding should be automatically controlled by a microcontroller. *Chemical expertise is needed for constructing the recipies. ---- [[projects:foam_rubber_machine|Danish Version]]
