This week we have worked with the 3D modelling of the system. We used Solid Works for this.

This is the first model, but we realized that there will be some changes so we started working on a new and more improved design.

The pump motor for prototyping is finished, but it seems that the motor may be too weak. 

The pvc tube we bought is too rigid for the motor, so we tried one made of rubber. This was still too rigid. We therefore ended up buying a new, softer one made of silicone, which we will receive next week.

Components used so far:

Stepper motor board

Stepper motor

3d printed vacume pump

Arduino board, uno

Wires
