Automatic dust collection

I'm finally looking to get a serious dust collection system installed. There's been a few recent threads of interest. I'm wondering if any folks have automated their systems (Dust collector turns on and blast gate opens when the machine is turned on) and what might be recommended for a non-electrician like myself.
There are a few automatic blast gate systems such as the iVAC but they are over $150-275 for each tool .....https://shop.ivacswitch.com/

Found this one too......https://grngate.com/product-pricing/ which looks good and maybe even user-friendly. $500 just to get the starter system.

The Artuino home-made systems seem too difficult for me.

I should get the parts from Amazon today for my automation. I think it was a little under $40. I will use low voltage switches meant for a security system on each blast gate to turn on the DC when I open the blast gate for that tool - and shut the DC off when the gate closes. A little 12V power supply will run the signal for the switches to flip a relay which will turn the DC on and off. I'll try and post details when I have it done - should be next week some time. I will have to run little wires to each blast gate so that may add some cost, not sure how much little wire I have. I only need something like you use for sensors on garage doors or for a door bell, should be pretty cheap and I think I have some.

Maybe @Jeremy Scuteri can chime in with his automation system. If I remember correctly from the shop tour, he built it himself and involves what amounts to a doorbell button at each tool to turn on the dust collector and route the blast gates to that tool. He's an electrical engineer, so it might be more complicated to make than you are looking for, but it was impressive.

I have homemade blast gates on my system. I use low voltage switches powered by a door bell transformer (12v, I think) to start the system. Whenever a gate is opened it makes the low voltage connection that triggers a solenoid switch on the unit. The solenoid switch is what controls the 240v power supply to the dust collection. If I remember correctly I ordered the transformer and solenoid switch from Grainger's. I had the door bell wire already. That's about all you'll need to get it wired. My gate switches are just a piece of metal that bridge the connection whenever the gate is fully opened.

There are solutions that open the gate and turn on the system whenever the target machine is powered up. That's the next level. Personally, I'm fine with what I have. I sort of like having the system come on independently of the machine, and only when the gate is opened.

My table saw, radial arm saw, belt/disc sander, (2) bandsaws, planer, miter saw, lathe and drill press all have individual blowers or vacuums which start when the machine starts. All other equipment, drum & edge sanders, 20" disc sander, jointer, shaper, router table, work bench have ducting with a slide gate connected to a common blower which is remote started (3 remotes so one is always within arms reach). When I go to a machine I open the slide gate, push the blower remote start and go to work. When finished I close the slide gate, therefore all slide gates are always closed except when in use.
I also transport all dust/shavings outside, so I really just "transport" everything. No filters to clean, no bags or drums to empty.
It works for me.

I have manual blast gates, but DC is controled by a current sensor mounted in panel box. Machine turns on, so does DC. Machine turns off, ten seconds later DC turns off. This is based upon an article in Aug 2000 FWW, to which I added a delay on break timer. Everything is mounted in panel box. Sensor is from SSAC, which isn't the cheapest.

I sent a PM to Bill, but if anyone else is interested in my fully automatic system with electro-pneumatic blast gates search the archives. It is still working great, almost 12 years later! :) There are multiple posts containing most of the info. I got two pages of results searching using "autogates." Unfortunately, there are no photos- the links are broken- happened sometime during one of many NCWW forum software migrations :(. I still haven't fully figured out how the photo albums work, but my home made cyclone album https://ncwoodworker.net/forums/index.php?media/albums/homemade-cyclone.808/ has many of them, the remainder are in my general photo bucket ("media"?) on pages 40 - 45. Much of the same stuff is likely also on Sawmill Creek, though believe you must be a contributor to see photos now. There was a great video I shot and uploaded to the American Woodworker website back then, but that died with the magazine and they didn't convey when PopWW took the AWW materials. Anyway here are some links to posts (w/o photos):

Here are some threads from 2008:

This one I was much farther along. I updated it when I added current sensor switches at the outlets:

The only thing my system does is allow me to have a whole bunch of inexpensive buttons around the shop that turn the dust collector on and off. I still have to manually open and close blast gates. Automated gates would be really cool.

I got the stuff to wire up my gates (LV) but I decided to try something different. I ordered a cheap remote control unit that a reviewer says works well for him with the same DC I have (2hp HF). It was less than $20. If that works, I may not go to the trouble of creating my relay setup. I only have three blast gates and will probably add no more than 2 more (I use flexible hoses to connect multiple machines from one drop). So wiring each gate is not a huge deal but I didn't do it before I installed them so it will be more difficult now.

I have been using a Arduino Mega based automatic Blast Gate/Dust Collector controller I been developing for a few years. I have current switches installed in outlet boxes used by tools connected dust collector. These are connected the controller using 2 conductor alarm wire.

Each blast gate I modified has a pneumatic cylinder and 24V 5 port valve to open and close the blast gate. Gates are metal ones I got from Oneida with my dust collector. Each gates valve is connected to the controller using more 2 conductor alarm wire.

Before I designed the controller I was using an X-10 remote controlled outlet to turn on/off dust collector. So I use the same X-10 controlled outlet with a X-10 PL513 Power Line Interface module connected to the Mega to control the dust collector. I also have other X-10 modules for controlling power to other stuff. Other stuff such as air compressor, exhaust fans and some lights and turned on/off by the controller when I enter shop and turn lights on.

My dust collector is and Oneida 1.5 HP internal filter model I bought in about 94 or 95 not long after Oneida starting selling them. If you let the dust bin fill up saw dust get packed all around and in the filter and is a real mess to clean out. So I happened to an IR distance sensor so I decided to use to measure dust bin level. This is also connected to controller and controller wont turn on collector when level gets to high. My original distance sensor was not ideal so I recently acquired another which I think will work much better.

My dust collector has an internal filter which has to be cleaned periodically. Since cleaning it is a pain I decided to add a differential pressure sensor to it and monitor the vacuum level. Controller turns on an indicator when I need to clean the filter.

I also have a remote controlled JDS air filter which I used to have to manually turn on. When I acquired it the remote was lost. So I started to just build a remote but decided to control it with the dust collector. I took out the JDS controls and replaced it with a ESP8266 wifi processor. It was easier to just control it from my phone. Mega didn’t have network access yet. Before I got the air filter I had been working on another project to monitor the dust levels in my shop which used a ESP8266 processor and a SDS011 particle sensor which sent particle counts to ThingSpeak every 3 minutes. That’s why I got the air filter.

Again my GEEK took over and the air filter in now controlled by the PM sensor. Air filter is sent PM levels via ThingSpeak and determines the fan speed and run time. Since Air filter has a filter it is also going to get definteral pressure sensor sometime.

Since my dust controller prototype is sitting on the headstock of my lathe I decided that this year I was going to tidy it up and put it in a box. I have designed PCBs for it and just received them a couple of days ago. I’m also going to do PCBs the PM sensors and maybe the air filter.

I plan to build some vintage looking electronic equipment enclosures to house them(Dust Collector Controller and PM Sensors). I’m also planning to install my own MTTQ server/Database and get away from ThingSpeak.

I used a processor to control everything but I think it would be possible to just use current switches, at off delay relay and some cheap 5v relays if you just wanted to control dust collector and automated blast gates.

I have probably gone on a bit to long with this posting but if there is any interest and it’s appropriate I can post some photos and more details of the stuff I’ve done to date.

I have my table saw and planer connected to one blower hooked up to the Long ranger system with wired blast gates with contact switches.. Just open the gate and the collector turns on. The router table, band saws lathe and sanding machines are all plumbed with the rockler quick connect system and connected to another blower that is hooked up to the long ranger remote system. Just open the gate push the button and I am in business. I also vent outside like Charlie, so no mess. Works like a charm.

Michael,

I'd be interested in more details as well -- another member here (Alan in Little Washington) developed a pneumatic gate system for his dust collector (a Bill Pentz design) that activates automatically with power tool start up. I have a Clearvue CV1800 with remote control and a bin sensor system to protect the filters from bin overflow, but I use manual gates.
