Warning!! This is Geek stuff!! I wasn't exactly sure where to post this but it really applies to any device you might want to remote start. About 3 years ago I bought the three-remote control set from Harbor Freight to activate my dust collector, shop vac, and window fan I use when I spray finishes. I realized the remotes weren’t intended for the current draw of the dust collector but figured I would use it until it burnt up, which I thought would be a couple of weeks. Well, three years later it finally burned up the circuit. So I took the unit apart, repaired the circuit board, and then used an enclosure to house a 30 amp contactor and the remote switch – it works great! And now I needn’t be concerned about the remote not working since the current for switching the coil on the contactor is only about 0.04 amps (4 watts). My only real concern was whether the remote would activate the relay switch since it’s enclosed in the steel enclosure but it seems to work just fine from anywhere in the shop. Before the dust collector really gets going you can hear the contactor close when I press the remote and that’s a good sound! David

Not a subject we have talked about here but we all need exposure to the latest with the crisis. Our turning club (Magnolia Woodturners) had a IRD last Thursday with Mike Mahoney , world renowned turner. The IRD is a method of doing remote demos and allowing interaction via Zoom and other social platforms. The demonstrator does not have to travel and everyone is at home. In normal times the viewers can be in a group. This method of viewing a demo can give you a better look at what is going on that being there in person. We had 50 persons including Mike present for the 3 hour demo. He uses his videos and fast forwards to teaching points then draws on screen. It is a very effective teaching method. There are now a growing core of demonstrators turning to this method of demo . Benefits for the club are that we can share with other clubs and even club members who cannot get out can be present for a demo.

This isn't anything new to most of you but I just picked up the HF wireless remote receptacles - $20 for 3 receptacles and one remote. They're good for 15 amps each. I was looking at the high dollar versions and then kept hearing people talk about using $7 Christmas tree light remotes or picking up $5 versions on the bargain table and I really didn't want to spend a bundle on this. But it was getting old being all set up to make cuts and then realize I had not turned on the DC or shop vac, have to put everything down, walk across the shop to turn the DC or shop vac on, and then get ready again to cut or sand. My concern was the current draw so I checked them this morning and to my surprise the running current on the HF dust collector is 10.5 amps. My '6.5 HP' shop vac pulls 12 amps. If I recall the HF pulled nearly 12 with the 5 micron bag filter but I just changed to the Wynn 0.5 micron filter with a lot more surface area and correspondingly a bit less current draw. I guess time will tell as to how these hold up but as of now I have one spare. $20, not a bad deal - David
