Remote Control for Dust Collector V2

[@AlAl-nm6dn]

Hi just wanted ask what wire goes to the Drain on the mosfet. is it the lead going to the relay. Thanks

[@knotnowwoodworking]

Yes, the Drain goes to the relay.

Can this be made without using a line in on both the load sensing side and the shop vac side? I would like to make the entire thing in one container with only one power chord.

[@knotnowwoodworking]

Absolutely. The only reason I have a separate line-in for each is so I can have each piece of equipment (e.g., Miter saw and Shop Vac) on a different circuit. If your loads are moderate, then you can easily combine everything so it runs on only one circuit. Before you do that, though, try running both items on the same circuit to make sure it handles the load without tripping the breaker.

@@knotnowwoodworking I actually built John's 2nd version exactly as in his video with the same parts. I actually built 3 of them since I thought the 1st one worked. As his demo shows, mine will turn on my drill press (or my shop vac) WHILE USING MY HEAT GUN. However, the shop vac will not turn on when using my table saw (instead of heat gun). When using my miter saw and shop vac, the shop vac starts when i start the miter saw, but dies out a few seconds later. Any idea what is going on? Can I modify his design that I already made to make it work or should I use yours from scratch? With all of the money I have spent on parts so far I could have bought the real deal. Now, it's an ego thing. I want to make sure I can do it. Could I at least use the relay from his latest design, since I now own 3 of them?

The load sensing circuit has a minimum current requirement for turning on. During my tests, my circuit required a draw of about 8 amps before it would work. I suspect your heat gun is drawing enough current to make your circuit work, but your other tools may not. To test this, plug something else in with your table saw and see if the combination draws enough current to make it work. Same thing with your miter saw. You want something that draws 2 or 3 amps--you can try several 100 watt incandescent bulbs if you have them. If everything works with the extra load, then the problem is as I described. In the very last version I made (no video, sorry), I bought a ready-made current sensing module that is adjustable so almost anything triggers it.
