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!

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.
Thanks the info. I came searching the comments for "contactor" (I thought one should be used but wasn't sure).
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.
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.
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.
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... czcams.com/video/uTvUwe2BXGg/video.html
how great it is to combine carpentry and electronics , this is AWESOME !!!!
(And cleaning)
The Shop of The Future is NOW!
I saw your dust collection cart video
Hitting the like just for that last bit, love how your so happy to open source your stuff, it's so refreshing and just.... nice
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
Bob, you're an inspiration! I'm moving next month and will FINALLY have a shop! I'm looking forward to doing these kinds of projects myself. Keep up the good work man!
This is such a fantastic video!! I've been watching you for almost a year now and I appreciate the detail you put into your videos. It's really inspiring me to start making. Keep it up Bob, I support what you're doing.
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.
You're very kind Daniel! Thank you , I really appreciate that :)
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.
I've seen a few other people use the foil tape for the same reason. Seems like a good call.
I have been looking forward to this for a long time! I love this thing! Awesome! Way to go!
I can't believe the timing. I am setting out in December to do this project as well. You are making my life so much easier. Thank you sir! Nicely done
This is completely and absolutely genius! Glad I've been following you all this years.
Pretty nice!! I love your videos. Keep on with that big creativity, you're an example to follow.
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!
Aww, thanks Eric!! I really appreciate that!
OMG! I knew I needed to learn how arduino's worked! I have had a S&D dust collection system since 2007 and never been shocked from it. Great job Bob.
The coolest! Glad you decided to release the video this week. On Twitch you mentioned waiting to get the part in, but this was great.
There is something fundamentally satisfying about seeing code become a thing in the real world 👍Awesome indeed,
I LOVE the music you came up with for this one! Very Blue Man Group'esque! Very appropriate for a video about pipes!
Bob, you're amazing! After watching a handful of videos, I could easily see you having your own show! Thank you for all the great videos!
Bob, thank you so much🙌🏻This is awesome!!! You have done a big service to our community by engineering this and freely sharing all your hard work. Cheers man🍻
You're a mad scientist and I love it. Every time I see a notification pop up from your channel I get so exited to see what you've done next. This is no doubt one of my favorites.
You’re very kind, thank you!
Oh man, what an awesome project. This is why I Like To Make Stuff is hands down my favourite CZcams channel.
You're very kind! Thank you so much!
This is probably the coolest thing I have ever see! I love the laughter of success at seeing the blast gate working during the testing
I love how positive you are. I always had trouble finsihing/exectuing my projects, I would do all the work, but the never do anything. It's really satisfying to see someone else do something.
I love your Arduino projects! Nice work
The moving camera really adds a lot, this was a really cool video
I was waiting on this video! Thanks Bob. Definitely one of my favorite practical use videos.
I'm really loving how you've stepped up your production value. You already had the most accessible DIY channel in terms of content and delivery, but now it's just next-level awesome. This is broadcast-quality stuff here. Keep up the great work!
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)
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.
If you run 2 tools at the same time, what happens (planer and table saw for instance) ?
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.
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!)
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?
Is it just me, or have you gotten a lot happier since you've moved? Not that you seemed unhappy at all in Savannah. You just seem to be giddy all the time which is freaking awesome.

He looks somewhat younger too.
it's the lighting ;)
I really like the simplicity of the fold out design. Nice job!
Colin Furze montage feel! 9 minutes to not only get a working dust collection installed but to automate the whole thing with Arduino and relays! This is what makes your channel so great! Compact video full of information! Great job videoing as well Josh!
Ha, thanks man!
I love all the work you do its so amazing!
Amazing, learn to code is the new challenge of our generation! Greetings from Brazil Bob!
Using an Arduino is an excellent way to start. The code can be relatively simple for small things, and knowing it scales to big opportunities like mechanical engineering and automation engineering.
Your genuine excitement at @6:23 is wonderful
I love your channel... I look forward to seeing your videos every week. I have to say, this might be the most impressive thing you've done. Keep up the jaw dropping work.
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.
Really cool Bob! 👍👊
I have high expectations when I see you take on an automation project, and you exceeded those expectations yet again. Great job explaining it all! You're going to get a TON of use out of this being automated. No more being "distracted" with opening and closing blast gates. ;)
Loved the filming on this one. Great project and good work Bob and Co.! :)
Yes! RoboDustBot comes back to life even better in v2!
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!
The videos have gotten a new type of dynamic and im really liking it so far. Keep it up Bob!
your first dust collector video was so fun to watch i saw this video on my suggested and thought it was that, was going to watch it anyway but was so happy to see this!
You and josh are having too much fun. Love it. Montage time!
It really is awesome having him around!
6:22 When your first light the led on off arduino project work, haha!
I have never seen a maker so down to earth, yet so intimidating! Holy guacamole was awesome. Bravo, this one had to feel great when it was all said and done. Great work sir
Soooooooo cool, all disciplines at play
This is a game changer, Bob.
One more thing, who is "we"? 1:00
And whoa, still getting used to the floating camera......
This is one of my favorites of your videos. Nice job! Love the montage time.
Bad ass brother!
David Allen
Lucas Braun yes?
"Close the blast doors! ... Open the blast doors!"
I love this one, normally your videos are one or the other. Woodworking or electronics (or metalworking) but this is one of those that the projects overlapped. I love those!
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.
Man project aside the music for the montage time was 110% on point.
Which Song is that? 😀
would love to buy a mug from you! an a nice black one with the orange logo
Perfect timing! I’m in the middle of rearranging my shop making my dust collection system rigid. I used to just roll the collector over to wherever I needed it.
That's a really nice progression from your last dust collection system, great work.
Oooo 2hp motor should probably use a motor contactor
Open the blast doors! OPEN THE BLAST DOORS!
I cannot get my servos to work, any ideas?
Awesome set up. I've had virtually this exact idea in my head for a while now, waiting on time to actually install it in my shop. Super cool to see it implemented! 😀
Awesome! It's a fun project but definitely takes lot of code tweaking :)
I suscribed to your channel two weeks ago. And i had so much fun watching older videos. Your videos are so great. You re awesome. Greetings from France (Sorry for the mistakes 😉)
Expand this x1000 and then Smog is history :)
RabbitRampage 😂😂🙈
who runs the camera?
Josh Price!
at 'I Like To Film Stuff' :-D
A Tripod??????
I love the small clear box that holds the electronics...
Very cool.
loved the Montage Transition (wave your hands fast) and music! super awesome
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
gareth scott, Can the micro PLC or the smart relays do what Bob setup do?
Well, it's that time again...for everyone else to be second. Because FIRST has been taken!
oh gee.... how do you always do it? ;) #KingOfFirst

Great Bob, since you talked about it on the Podcast, I've been curious about this project, it turned out awesome!
absolutely love your videos! i like how you combine a project idea with a bit of imagination and tech to create something of your own and freely show us all how to diy it. Appreciate it and keep up the great work. will absolutely try this idea when i get into a bigger shop. cheers mate.
Hello i'm french and i'm like to make stuf
Awesome... i dont have a shop that needs this, but love the project, idea and realization... excellent!
Heard you talking about it on the podcast, and it's always great to see plans come to fruition!
really nice job listing all of the supplies used on the project. That is a huge help!
Great project, makes me want to buy a DC system just build this! I love the automation videos and you continue to demonstrate "if you can imagine it, you can build it". Thanks Bob!
Awesome! I love all this stuff even though I have no idea how to do it myself. I'm 77 years old but that's just my body. My mind is that of a 12 year old and I'm deperately trying to soak up all the knowledge I can before my body gives out. Keep up the great work and all the super how-to videos.
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 🤜
exactly the dust collection system that i want to build - i’ll be downloading the templates right away! thanks for all the hard work bob!
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.
Ive been a fan since the beginning, and its great seeing somebody learn so much. I almost cant beleive that you went from building a wooden bike rack in a small shop to almost tripling your space and integrating impressive electronics into your buildjng. Keep up the good work!
Thanks for sticking around Drew!!
This video captures almost every aspect of why I got into woodworking and the maker space. Great job!! I can do the same - all I need to do is complete the assembly of my 3D printer and acquire a laser cutter!! :D Thanks Bob!!
I just found this channel, and this is by far the coolest channel I’ve ever seen! Now I’m gonna be watching CZcams for ever.
WOW , This is what creativity is all about , KEEP UP the good work and keep these coming please
Awesome! Love the combination of DIY/Programming/lasercutting/3d printing!
You are one of my favourite CZcamsr. I love all your projects man. keep up the good work.
Hey Bob, your original dust collection system video was the first video I watched way back when. It has been an absolute joy watching your channel and listening to your podcast through the years. Your geektastic maker dad lifestyle is an inspiration to us. Here is hoping for years more. The Cake is a Lie, even here in South Africa 🤓🖖🏼🇿🇦
Nicely done Bob! Great idea and well executed!
That's one of the most creative things ive ever sean anyone do with an arioino, good job thinking out of the box.
One of the best projects you have ever made, Bob. Bravo !!!
Thanks so much!
Loving what this channel has become and is becoming. Loving it bob. You single handedly made me love the art of wood working.
That's very kind Michael!! Thank you!
Very cool, Bob! Your work is so inspiring!
This may very well be the best/most useful one video yet! Im not a talented coder by any means, I see EVERYTHING in If-Else/else-if statements and thats not conducive to decent coding. Thank you so much for this!!!
Thanks Bob. That's a really cool system. I will certainly make use of it in my new shop.
Awesome project Bob combining all sorts of skills
Love this video, it was amazing! Great idea! But, you have some crazy editing going on.
I love watching these videos you make. With my background in software, I really enjoy when you use the coding to make your wood working better :)
Hey Bob awesome video, you have no idea how much i look forward to your videos every week, keep up the amazing work. :)
I really appreciate that!! Thank you!
Really good project, definitely adding this to my "list of things to make" bookmarks folder.
its the most practical and fun Project i have seen for a long time, damn good job
Dude, that is awesome. I really enjoyed this. Montage time was great.
Thanks Josh!
