How to reuse a fridge compressor to build a vacuum pump for RC planes wings carbon or fiber glass laminate
Fiberglass Composites provide unique and valuable benefits, from high strength-to-weight ratios, relatively low cost, durability, chemical, water and abrasion resistance all in one.
However the mechanical properties and performances are highly dependent on composite production conditions under which they are produced, from hand lay-up to vacuum bagging.
This project will focus on vacuum bagging process and show how to reuse a cheap refrigerator compressor as the main vacuum pump. This project is fully documented on my hackaday's pages here : https://hackaday.io/project/196665-a-vacuum-pump-with-old-fridge-motor
Firmware for ESP32 is available into this github : https://github.com/f2knpw/VacuumPump/blob/master/JP_ESP2_eVacuumPump_BLE.ino Android application is available into this zip : https://github.com/f2knpw/VacuumPump/blob/master/JP_VacuumPump.zip
A second version does exist allowing to drive a DC motor vacuum pump. This second project is fully documented on my hackaday's pages here : https://hackaday.io/project/197256-dc-motor-vacuum-pump
Firmware for ESP32 is available into this github : https://github.com/f2knpw/VacuumPump/blob/master/JP_ESP2_eVacuumPump_BLE_Wifi.ino Android application is the same (+UDP interface) and is available into this zip : https://github.com/f2knpw/VacuumPump/blob/master/JP_VacuumPumpv2.zip
