Share My Creation A vacuum pump with an old fridge compressor

Hi all,

It was a long time since my last post !
Here is a quick and dirty vacuum pump made from an old fridge compressor.

Starting the motor was the most complicated thing in this system !

Of course a little B4A application to handle the MMI.

All this free and opensource / open hardware.
