I made a new dust collection system and FULLY automated it using an Arduino Uno!!
Want to learn more? I made an online course!! arduinoformake...

Code: github.com/ili...
In my new shop, I hadn't properly set up my dust collection system. With this blank slate, I had an opportunity to improve on my older automated system that worked off a key pad. I wanted the ability to simply turn on a tool and the dust collector would fire up and all the blast gates to close like they should.
In a shop with many tools, there are valves that can isolate the suction to help improve air flow, the more tools you have, the more gates you would have to close in order to use one tool. With the help of an Arduino micro controller, I was hoping to automatically control these gates and have the DC turn on and off with the tool.
There are commercially available systems that do this, but they are expensive and don't offer a way to add additional IoT functions later. Eventually, I'm hoping to connect the system to other sensors set up around the room to make the ultimate workshop of the future!
I started by laying out the pipes that would connect the DC to each tool in the most efficient way. I found some drainage piping at Lowe's which was much cheaper than traditional PVC pipe. Because the walls of this drainage pipe were thinner than regular PVC, most of the blast gates and fittings wouldn't connect. Josh designed and 3d printed a bunch of adapters to connect the whole system together. After connecting all of the tools to the pipes and fittings, we played it safe and added a ground wire from one of the pipes to an existing ground wire in the basement. This is said to prevent static buildup which could be dangerous in a dusty environment, so I added it just in case.
With the ducting in place, I focused on the sensors that would read the amperage spike when each tool is turned on. I made a housing that the tools would plug into to receive power and also connect to the voltage detector that connects to the Arduino. Once you turn on a tool, an amperage spike is detected and an input signal tells the Arduino to shuttle the appropriate blast gates and to trip the relay that controls the DC. The blast gates are controlled by a servo mounted on a bracket that swings an arm connected to the gate. When the servo moves, the arm pushes or pulls the gate open or closed.
There are a lot of components to this system so managing all of the wires, plugs, connectors, and servos was very important. All of the connecters were pinned and protected with heat shrink, all of the wires were bundled and labeled, and the servos were dialed in to make sure the gates weren't hitting any hard stops.
The system works great except for one component that kept giving us trouble. The 15 amp relay that was controlling the dust collector would fail after a few days. After some research, I discovered that they were a bit underpowered for the 2 horsepower DC. I have ordered a beefier relay and when we get it hooked up and working, it'll be listed here. If you want the Arduino code for I made for this project, you can find it here.
I hope this project inspires you streamline your workflow and find ways to improve efficiency in your shop or home. If you liked this type of project, check out the others on the channel!

@zombiehunters6732 4 года назад

I saw your dust collection cart video

@Mr.Glitch247 6 лет назад

That motor is an inductive load (as opposed to resistive) if you look at your relay spec sheet, it is actually rated LOWER for inductive loads. This has to do with the "Back-EMF" generated by your motor as the magnetic field in its windings collapses when you turn it off. These effects can cause arcing across the contacts and reduce the lifespan of the part as they become more and more pitted. Most commercially available automation relays I have seen really only go up to about 3/4 horse for inductive loads. That could be why you were seeing issues with the performance of the one you were working with. Usually when I have to control something above about 1 horsepower, I end up using a motor-rated contactor. Don't throw out the relay though! You may need to use that to activate the contactor, since you probably won't find one that uses coil voltages and amperages that an arduino can source. Sorry for the long post... I design automation control systems for mechanical equipment for a living and thought some could benefit from that experience.

@byoung255 6 лет назад

Thanks the info. I came searching the comments for "contactor" (I thought one should be used but wasn't sure).

@Mr.Glitch247 6 лет назад

No problem! And you're looking to make on of these, I might suggest going with current switches instead of the voltage sensors as well. They use the electrical hot wire as a sort of 1-turn transformer. The resulting induced current in the device powers up a small internal circuit which closes a contact after it reaches a threshold current. They are very reliable and have the benefits of being a simple digital input to the micro-controller, and of being clamped around the tool's power feed as opposed to in line with it. The smallest ones I am aware of have a maximum current rating of 135A and I have used them on loads as small as 10mA ( with multiple wire passes through the core though, mind you ). Typically they like to see a minimum of about 3A for reliable operation with only one pass.

@byoung255 6 лет назад

Matt DeSalvio I want to build a similar system in the distant future. Currently building a CNC machine, and working out how to wire a contactor before servo power supply and spindle inverter. I've got a degree in electrical/electronic engineering but I don't have much practical experience.

@Mr.Glitch247 6 лет назад

Ben Young I can tell you that in the real world of practical "control systems" only 4 things exist. They are as follows: 1) Digital Output 2) Digital Input 3) Analog Output 4) Analog Input. THAT'S IT! All of the KVL, KCL, differential equations, Laplace transforms and all that other magic has already been done and baked into the arduinos and the spindle inverters etc... I've found the most useful part of my mechanical engineering degree to be the experience it gave me in attacking problems I know nothing about. I think you'll find the same. In short, a contactor is just a big relay. It takes a coil voltage, and draws a coil current which you will probably need a regular relay to control. Your spindle inverter, which I am assuming probably is some sort of variable frequency drive, just boils down to Start/Stop (DO), Speed (AO), maybe Direction (DO), maybe Proof of Operation (DI), maybe some sort of alarm contact as well (DI). All you need to do is power these things up and look at the spec sheets to find out what terminals do what. You'll need to know how to interpret the signals the system sends you, or how the end device will interpret the signals you are sending. Because an AO is likely to be just 0-10VDC, and that doesn't mean anything. Take your speed control, for instance, your inverter takes a 0-10VDC input for It's speed command. You tell it 5 volts. How fast does it go? You need to map that to a useful span on your end, that is the same as the mapping on the inverter end. So you can tell it go 1500 RPM, and it goes 1500 RPM. I hope all that makes sense! TL;DR: DO,DI,AO,AI.

@Mr.Glitch247 6 лет назад

Serendipitously, AvE posted a 3 phase variable frequency drive teardown only a couple minutes after I posted that comment. It's a small internet huh? Here's the link if you want to know what's in those things... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uTvUwe2BXGg.html

@Fixthisbuildthat 6 лет назад

That's a sweet setup, Bob. Not sure if you put it in the code or not after the first iteration, but leaving the gate open and collector on for 2 seconds after the tool goes off will make sure any lingering dust is evacuated. That's what my commercial iVac switch does on my miter saw. Not dealing with moving hoses or opening blast gates must be nice! (note to self...get on that)

@Iliketomakestuff 6 лет назад

Thanks! Yeah, the gates stay open after the tool stops and the collector runs for a little extra time. The gates don't change again until you start a new tool.

@Dogeek 6 лет назад

If you run 2 tools at the same time, what happens (planer and table saw for instance) ?

@Iliketomakestuff 6 лет назад

Once 1 tool is running it ignores the system until it's turned off, then a fixed delay time is over. That's all just code behavior.

6 лет назад

I was gonna make the same suggestion, I also have a system based on iVac and making sure that the dust gates open / close a few seconds before the DC start / stop really help! In my case I leave the dust collector running for ~50 seconds after stopping the tool, this way if I make multiple cut in a short period of time (e.g. with the miter saw) I don't go through too many start/stop cycles (your DC can consume up to 6x what its typical current consumption is when it starts! You probably want to minimize this). Your system is really awesome by the way! I'll probably use some part of it to improve mine (iVac is pretty cool but has its limitation, being able to make my own automated dust gates would be awesome!)

6 лет назад

Here's some documentation on how long and why you should keep the DC running once a tool stops: ivacswitch.com/wp-content/uploads/2015/11/High-Power-Dust-Collectors-Minimum-Run-Time.pdf , this is mostly for DC of 3HP or more but should still apply to a 2HP one?

@danielrisueno8003 6 лет назад

I've been subscribed to your channel for a couple of years (i think), and none of your videos has ever been a turndown. I find amazing how you combine your skills on many things to accomplish your projects. It is even more spectacular when it's about big projects such as this. Thank you for all your creativity and good work, and for inspiring us all.

@Iliketomakestuff 6 лет назад

You're very kind Daniel! Thank you , I really appreciate that :)

@Hppyzmbie 6 лет назад

There are hundreds of dust collection videos on youtube but you manage to take it to a whole new level. That 's why I love this channel!

@Iliketomakestuff 6 лет назад

Aww, thanks Eric!! I really appreciate that!

@handydan1591 6 лет назад

I’ve noticed your videos becoming different lately. Almost like your more excited. It’s been very entertaining and a real nice change bob. Very cool

@craftedworkshop 6 лет назад

Turned out great, Bob! I set up a similar system with iVac, the commercially available equivalent of your system. By the way, PVC cuts great on the miter saw. Makes super quick, square cuts. Also, if you want to hold the pieces together without making it too permanent, self-tapping screws go into PVC perfectly. I also taped my joints with aluminum foil tape, which helps eliminate any leaks.

@BruceAUlrich 6 лет назад

I've seen a few other people use the foil tape for the same reason. Seems like a good call.

@BronkBuilt 6 лет назад

Awesome stuff Bob. I understand how hard it is to explain code and programming without going on for 45 minutes. Don't let the haters get you down! Keep up the good work.

@JoeRKsChannel 6 лет назад

Great work, love the video! Only difference I'd suggest is using a Current Clamp/Current Monitor, opposed to voltage sensing. Video production in this video was amazing, keep up the great work!

@aldomorell7975 2 года назад

I used an Arduino to detect current to flip a relay and power a shop vac. You can make a simple current-detecting transformer by making a few wraps of thin (22-26 gauge) insulated wire around a ferret and using an interrupt pin on the Arduino to detect a small, momentary change in voltage. Put the insulated load wire through the ferret and when current flows the thin wires will trigger the interrupt on the Arduino. Easy, inexpensive and safe. (Digi-key carries many cheap ferrets) I used an output from the Arduino to switch a transistor that can handle the current to power a 5-volt relay with high, inductive load capacity.

@PJGalati 6 лет назад

Bob, this is totally awesome! I'm most likely going to move next year and a new shop setup will be needed. I've been thinking about dust collection for a good part of this year and I think I would like to have everything 90% like you have it set up. The only change I want to make is to locate the dust collection unit either in another room OR build it a sound proof enclosure as the noise level of those things is massive in my opinion. Either way, this might be my very first arduino build! I go for the simple stuff lol.

@dennismacwilliams196 3 года назад

@converdb 6 лет назад

Soooooooo cool, all disciplines at play

@toneystevens5023 5 лет назад

A ESP32 or 8266 would allow you to go wireless between the tools and the controller using WiFi or bluetooth. Motion detectors may be a better choice than current detectors. Better yet, both. Motions would turn the vac on when you walked up to the tool and the current detector would keep it on. I'd say you could use the same output on both devices to signal your Arduino. Also I'd add a long delay so that the vac stays on between cuts.

@gscott1604 6 лет назад

Great job, but i never under stand why people use Arduino when there is already micro PLC or smart relays with free software that designed especially for project like that and no need for acrylic box for protection, or convoluted programming. seems way over engineered for a simple dust extraction system

Many Thanks for inspiring me to figure out the Arduino to build this project. The only things I did different is use bigger servos (20kg of force) , making the servo mounts and arms from 1/4 inch plywood and a jigsaw and using a 5v/120v relay connected to a 240 Volt 2pole 2hp contactor with 120 volt coils. I just finished it today and is connected to 3 tools. It works great! Thanks again.

@m4vrick 6 лет назад

For driving your blower motor you should use a Solid State Relay, the most common are rated for 25A and it's simply enabled by a 5V signal, all the needed electronics are inside the box. Really a reliable and robust solution for this kind of application instead Chinese relay board.

@RyanGausMakes 6 лет назад

That's really clever! Love to watch these kinds of projects that combine lots of different types of techniques to create a useful final product.

@rish1459 4 года назад

I am so glad you mentioned the relay being undersized. I saw three very large concerns with that relay: (1) The connector used isn't rated for 30A, (2) The relay isn't HorsePower rated, and (3) The traces on the PCB aren't going to be rated for 30A either. I've done a lot of power electronics design & those failures are common with products produced in China.

@DavidBishopinc 6 лет назад

@Mtaalas 6 лет назад

You should wrap a copper wire around the pipe along the whole length before grounding it. The pipe is such a good insulator that it can't bleed the static buildup through it easily, by wrapping the copper wire around it, you decrease the resistance of the pipe through the whole length and the static buildup is less likely.

@DIYAudioGuy 4 года назад

You're the only RU-vidr that I have seen mention the problem with static electricity and dust.

@twilliamson3 6 лет назад

I just designed a system very similar to this for my shop. Here are some of the things i did differently. 1) I used Individual Arduinos at each of the Tools(2 tools per arduino basically), This allowed me to distribute the current measurements around the shop and kept the major cable runs down. I basically run a "control" cable around my shop, 2) I used air cylinders for my Blast gates, but i had them on hand, i like your Servo idea. 3) I used a Solid State Relay to control the motor on my HF Dust collector, I used another Arduino at the dust collector to run a piece of code that keeps the Vac running for 5Minutes after the tool has shut down, this is important because the cheap motors really dont like to be powered intermittently, they want to be on, or off, not starting. It also keeps Inrush in the shop to a minimum. I stole my concept from you but decided to take it up a notch. Once i have everything installed i will post a blog with the code and photos.

@WeAreTwoDoorsDown 6 лет назад

A couple changes I would suggest for anyone looking to build something like this is: 1. Use a "micro current transformer" to detect current flow instead. That way you don't have to break the A/C line. I don't trust those little boards. If you choose the right resistors, you could even still use the digital pins to detect "on" and "off". 2. Use a "contactor" for switching high currents, like the dust collector. Then use the smaller blue relay to power the coil on the contactor.

Do I need to updated the code if I use the "micro current transformer"?

Hi bob! Really like this project because it was both visually astonishing with the pipe system going all through your shop and the inclusion of an arduino to make it automatic. More like this please! :D have a great weekend, man 🤜

Heard you talking about it on the podcast, and it's always great to see plans come to fruition!

If you haven't already, look into an *industrial contactor* for the dust collector. It's just a big beefy relay, and some are designed to switch inductive loads like motors and blowers, which tend to have current spikes when switching, causing the contacts on relays to weld/stick.

About the static discharge... a copper wire screwed into plastic will not dissipate anything. Except in a small area around the screw... plastic is not conductive.
