LGTM. Maybe can add a link in the README.md? |

cool project. I'm a critical care nurse. Here some ressource you may look at to answer some of your questions: -Solutions to prevent the system from becoming unsafe if power is lost. It's not obvious to me on how to do this. Ideas welcome.***https://www.ebay.ca/itm/Power-Gate-Battery-Backup-DC-Power-Switching-System-Power-Pole-Amateur-Ham-Radio/141351712551?hash=item20e937f727:g:0YoAAOSwqu9U59gV to help with inspiration:https://www.youtube.com/watch?v=Y_92mDYfRGs |

Hi, Great project !!! Is it possible to get your hands on an M5stick? or ESP, RPI zero ect to get WIFI so we can make software to talk to it and get reading... (* I can help you setup apps, api ect ) M5STICK is here my advice because of buttons and display on board. I will try to make a europian version of parts you used Also, did you look at some sensors for feedback?

You may want to look at this project. May help finance further production and research. https://www.agorize.com/en/challenges/code-life-challenge Robin |

Hello @jcl5m1 Email me if possible: |

Hi Mr. Lee, We're reproducing your project in Brazil and I'd like to duplicate your repository and translate to Portuguese to avoid misunderstanding here... We are working hard to be prepared to face the pandemic pick in a few weeks. Do you agree? Congrats., |

Hello dear J. Lee First of all i want to say Bravo !!! but above all thank you very much for sharing open source. I would like to realize your great project but i have a problem with the fan. I choose the alternative of using a pump to inflate only i am not 3 pinout but only the + and GND, the motor is marked "HB-166E-RoHS RS-380SH-5021VN" My question, is it possible used a motor with 2 +12V output cables and GND? Thank you so much. (I would share the results if i manage to do your great project) |

Hello Col68. When I search for your blower, I find only the motor. It is possible that the blower number you are using is actually just the motor part number. Can you post a picture of the blower? Motor speed is monitored but I think a pressure sensor could be used to monitor pressure instead of RPM. |
|
Hı RWL-69 Thank you very much for your support, here are the pictures of the ventilation motor. I wish you happiness. |

Hello Col68. I am correct, the part number is the motor only, not the full blower. I cannot find the exact model number in my search but I can find the series of motors and they work off a wide variety of voltages and speeds which doesn't help in your case. From what I have looked at in this project is that the code (third pin) is being used to calculate the pressure from the motor. It could be used but you would have to modify the code to change the speed of the motor and control the motor due to rates and pressures. Do you have an idea of flow rate and pressure (cm of H2O)? It is possible but the control would need to be modified from the original project. I will have to look at it further to give an exact answer. |

Hi dear RWL-69 Respect for your help. I have not tested for flow and pressure (cm of H2O The exact model is like this : Unfortunately i don't have much programming knowledge to modify. I have an L298N module (motor controller) but i have no idea how to integrate it into the project. I think I will try to find the ideal fan, in any case thank you very much for your support. Respect to you. |

Hi, I'm trying to build this ventilator with a simple electric inflator pump. Currently, it is able to reach a 26cm H2O (13cm heigh) at full power. Right now I'm doing a sort of stress test in order to assess its reliability. One can see the manometer video here: https://photos.app.goo.gl/s3gQGS5cEDV4YeMaA Do you think its pressure and control are good enough? |

I found this book online for free: 'Principles and Practice of Mechanical Ventilation, 3e' https://accessmedicine.mhmedical.com/book.aspx?bookid=520 . I thought it might help, if you haven't already seen it before. |
