Building a tool-triggered dust collector system
zhlédnutí 36KPřed 7 lety
I used an Arduino, two relay boards, and current sensing transformers to automatically turn the dust collector on whenever a tool is switched on. Total cost for this project was under $100. Code and more information is available on Github: github.com/Sinorm/DustCollectorControl/wiki

Pub with Cold Beer near Phong Nha - Ke Bang National Park is well-known as a great place to hang out with a cold beer and have a super fresh farm-to-table chicken dinner served with peanut sauce and greens grown on-site. The chicken dinner can be as DIY as you want. We did the killing and plucking of our dinner.
Hyperlapse of Hai Van Pass in Vietnam
zhlédnutí 421Před 8 lety
The descent down Hai Van Pass between Hoi An and Hue, Vietnam. The hyperlapse is at 4x normal speed. This is the mountain pass made famous by the Top Gear Vietnam special, and it was a beautiful ride despite the "ocean cloud pass" presenting its namesake clouds on the north side.
When was this?
Back in 2015, just never uploaded it to CZcams
He had a plan.
Hey just attempting it is better than what most people can do. 👍🏻
And he can say he skied Corbet's Couloir.
That's a bucket list for me, I stood at the top once when there wasn't enough snow.
The board and all the connections should be inside a junction box (even if its a homemade junction box), especially considering its located in a dust producing environment. Otherwise, very clever. Beyond my limited electrical intelligence envelope, so I guess I'll stick with my remote.
why did you need to relays?
My dust collector is 240 volts, so you need to switch both hot wires. If you are controlling a 120 volt dust collector you would only need one rely.
@@rob_smith im about to do a similar project myself and thats why im asking and im not saying your wrong because im no expert. But the relays have 240vac written on them, doesn't that mean they can handle 240ac each?
kezzaman 240 volt power has two hot wires, each 120 volts in opposite phase. Therefore you need to switch both wires requiring two relays.
A fire waiting to happen the way it is set up with Romex exterior house wires instead of SO cords, tapping in with some cords not meant for the current draw. Yet thanks for the visual on the system, just make it safer. However much dust collection you have, you will have fine particles of dust that can catch on fire with a random spark. Romex is not an extension cord.
Those relays should be inside of a listed box. Reminds me of the days guys use to run their amplifier power thru the fender without a fuse and wonder why their car caught fire.
Just what is was looking to do. Thank you for sharing.
Does each blast gate open and close with this system?
You are one clever dude
I was going to build this but decided to make a Star Trek Transporter System first! Complicated without specialized knowledge.
You cannot use typical current transformers on a neutral line.Those are NCT's which are used on a ground fault system to verify discrepancies between the current carrying conductors (the hot lines) and the neutral and report back to the GFI on whether it should trip or not.
Waiting for the follow up video to show exactly how you put this together
I can't knock you for getting out there and doing something but this is way over complicated and convoluted. Put the current sensing relay in your electrical panel. No need to have wires running to every single tool. Also the circuit board and arduino is not necessary. Cr magnetics make a current sensing relay all in one package. If you are using more of a load that that relay will handle the key have that current sensing relay trigger a larger twist or even better a contactor. Neat and tidy, no wires need to be running outside the panel assuming you have a dedicated line running to your dust collector which I'm sure you do.
kpxoda1 - i just found this video, and have never played with a current sensor, OR an arduino before... so was just going to do this same thing, so you're saying instead of having the sensors on each tool, that you could, for instance, (assuming you're using the actual romex type wiring from the panel and ONLY tools use that circuit), that you put the sensor on the wiring in/out of the panel, and have that turn the dust on? so you would have to have a separate circuit for tools that DO use the dust collection and tools that DON"T use dust collection?
@@rapunzeleh546 That is correct, look up CR magnetics. They make the part you will want with a 20 normally open contact. There is alot of different specs you can get it in though so download the datasheet off the website and it will have a key to explain the model numbers and such. You can then sometimes find a used one on eBay. I think a new one is like $80. There are some genaric ones on ebay as well and they are a bit more universal having switches and dials on them to configure them to your use. Personally I prefer to buy quality American made (sometimes American designed) electronics
@@rapunzeleh546 Oh and if the dust collector or load that you want to switch is too great for the 20a contacts on that part I told you about you can simply add a contactor and have the current sensing relay trigger the contactor and the contactor turn on the dust collector
kpxoda1... uh... you had me up until contactor. was going to buy a 30amp relay anyways... i got one of those double barrel monster 3hp 220v collectors...still have to upsize my cyclone first though... matthias wandel has got some awesome projects - guys' a freaking evil genius when it comes to woodworking. he also has a relay box to turn on the dust stuff. saw one 'iliketomakestuff' i think.. he's even added servo's to automatically open the gates, but that seems a little unnecessarily whiz-bangy. if i'm standing right next to the tool, opening a gate just isn't a biggy. cool, but lots of other stuff to spend my dubloons on!
Why not use 1 current relay and run 3 or 4 machines to the common they all share in one circuit, that means one spst relay to the dust extraction hot lead with a 24 volt transformer and no ardunio ( which I don't know how to make ;) ) easy and cheap---.
It's because with the Arduino he can open the gate before the dust collector start and he can close the gate after the dust collector shut off. Without Arduino you cannot control all your elements of your dust collection system. Just take a look at those small modules Arduino and you will be surprise what we can do with it . He can put a dust sensor in his bag and it will light a red bulb with mean it's time to empty the dust bag or container. Thousand of possibility with Arduino.
I like it. I think I'll try it with something to detect the sound of the power tool. It would be less wiring.

Dear Rob, excellent. Nice to see this project and your job. Big hug from Brasil Said Choucair
Excellent. Thanks for taking the time to show it.
Dear Rob Smith, Thank you very much for this excellent video. This is something that I looking for a long time. I currently work with a few voltage sensors SCT-013-030 30A. I was wondering if there is any way for adjustement this code from your video to my voltage sensors? Would you be able to help we with this and write me what I should change in code? Thank you in advance.
I've been looking for a 220 v remote control for my dust collector for a while but with no luck and I would really appreciate it if anyone can help. Thanks.
eBay is your friend. I saw a couple of different models on there recently.
Hi Rob- I love this idea! I bought your suggested Sparkfun supplies, built the device, and am testing with two lamps -- the "saw" and the "collector". The problem I am having is when the arduino is powered on, after 2 seconds the relay closes and the "collector" turns on. This happens without the "saw" being on, and even if the CT is disconnected. Also nothing seems to trigger the "collector" off. I am using a 13v 1500mA power supply. I've checked my wiring. I figure this must be in the code (?) but I'm new to Arduino and coding. Any thoughts or suggestions would be appreciated!
Make sure your computer is connected while testing the system, and then you can use the serial logging output from the Arduino to understand what the software is doing. If you look at the code you'll see there are debugging statements throughout the code, just open the serial monitor while the Arduino is running and connected to your computer and you'll see the output. In the Arduino IDE, it is under Tools -> Serial Monitor.
Just the same project I am working on :) Love it. Going to try and make the dustports open and close automaticaly. I have a "big" woodworking shop and 8-10 moulder, shapers, saw etc so having it all turn on when I use it will be a lot more easy. TR
Do not know if you will reply, but fingers crossed :) How did you attach the current sensor. Did you use the 3.5mm jack or did you strip and solder it to the wire going to the Fundino ?? Also how do your blast gates operate? I think I am going to try stepper motors and a gears.. I have ordered your wish list so hopefully I will be able to make this. Intensive Arduino teaching ongoing now :) Thanks for the video and webpage with links TR
Currently my blast gates are manually operated. I have considered automating them but haven't started working on that project yet. The hardest part is going to be attaching motors to the blast gates to get them to open, I would probably use linear actuators but these are not cheap. It looks like you can get some linear actuators from aliexpress.com that aren't too expensive, so that might be an option. I cut the 3.5 mm plugs off the current transformers, soldered the bare wire so it would be stiff, and then plugged the wires into the female headers on the protoshield. You can purchase 3.5 mm plugs and solder those onto the shield instead, but I didn't think that step was necessary. One quick note since you mention having 8+ tools: the standard Arduino only has 6 analog inputs, so you can only connect it to 6 current sensors. You could work around this by having multiple tools share a current sensor, or you could add an extra board with more analon inputs. I'd recommend trying to just automate the dust collector power first and get that working, then move on to the blast gates. It should be a good project, let me know how it goes!
