Using a little Arduino hardware and programming YouTuber Brumberjack Woodworks has created a fantastic automatic dust collection system for his workshop. Providing an easy way to collect dust from any of the machines he may be using. Equipped with servo mounted blast gates the desk collection system Arduino code is available to download from GitHub from the link below. Check out the overview below to be taken through the complete thought and design process of system and its implementation.
“This whole system starts with a heavy duty dust collector, which is essentially a huge vacuum cleaner. The exact model isn’t that important, so long as it can handle the workload. Luckily, the key part of this system design is valve-based direction. By only opening the valves you need, you can reduce the necessary capacity of the dust collector. “
DIY dust collection system
“Brumberjack_Woodworks created his own 3D-printable ball valves for this system. Each of the ball valves is massive, so they can handle a lot of air flow and dust. They have large 35KG servo motors for actuation. The ball valves simply mount inline with the dust collection tubes running to each machine. By opening and closing the valves, shop workers can control the covered areas. Importantly, the PVC pipes need internal grounding to keep static arcs from igniting sawdust in the air.”
“An Arduino controls the operation of the servo valve actuators. Power for the servos comes from large external power supplies, as Arduino boards cannot output the necessary current to operate these heavy duty servos. Simple push buttons connected to the board tell it to open the specific valves, so a button can be mounted next to each tool for easy access.”
