VentilatorPi
by GrabCAD
Last crawled date: 2 years ago
A low cost ventilator which is supposed to be buildable by everyone who has a 3d printer.
The ventilator is controlled by an arduino uno connected to a Raspberry Pi. The Raspberry Pi is an Azure IoT device which enables us to continuously develop the code for the Pi as well as monitor the sensors of the arduino.
You can find the first build version of this ventilator attached as a picture. I'm going to upload the picture of the second version as soon as it comes out of the printer.
Code will be published on GitHub within the next days.
Materials:
freezer bag, PLA filament,
12 * bearings (5x11x5mm),
fishing line for the pulley system,
M2.5 and M3 screws
arduino uno, raspberry pi,
Stepper Motor (in my case the QSH4218-35)
Motor driver l293d
Step file of the stepper motor comes from https://www.trinamic.com/products/drives/stepper-motors-details/qsh4218/
The model of the raspberry comes from https://grabcad.com/library/raspberry-pi-3-model-b-reference-design-solidworks-cad-raspberry-pi-raspberrypi-rpi-1
and the model of the arduino from https://grabcad.com/library/arduino-uno-8
