3D Model + PCB + C Code
The 3D model of my final project is made with On-Shape and it is shared on-line. You are free to download its parts in order to make it at your Fab Lab.
Processes employed
Impeller part:
Designed parametrically with OnShape
Processed with laser machine
Assembled with bolts
Motor system:
The support that fixs the motor to its frame is designed parametrically with OnShape
The support have been processed with 3D printing
Frames part:
Designed with OnShape
Processed with laser cutting machine
Case system:
Designed with OnShape with only press-fit joints
Processed with laser machine
Carbon filter part:
It is hand-cutted and located on its frame
Electronic board:
Designed with Eagle
Processed with milling machine and hand-soldered with its components
Program to turn the motor at three different speeds done in C language
