I also made a controller to control the dust filter in my shop.
This is all the necessary information you will need if you want to make your own dust filter controler.
I also programmed a Windows program to control the controller. The program includes an installer with Microsoft ClickOnce technology. It will install by itself and check for an update each time you launch the program.
I also programmed an Android App to control the controller with your smart phone. You can download the Android App here or use this QR code. Version 1.0.0 is the current version
