I wanted a vacuum pump to laminate RC planes wings using the "vacuum bagging" technics.
This is the second version of my PCB allowing now to drive :
- DC motor pumps
- Brushless DC motor pumps
- 230V AC fridge compressor
This video demonstrates the system running and the "quiet" regulation of pressure.
The full project is open source and open hardware. You can find it on my hackaday's pages here :
