Hi!
I was wondering if anyone could give me a few hints / pointers on building blocks in the following design / idea:
I have a few powertools that generate dust; circular saw, sanding machine, etc. And, I have a dust extractor / vacuum cleaner. My idea was that instead of hearing the constant buzz from the dust extractor, it could turn on and off depending on the state of the power tools; eg. the current drawn through the outlet they're connected too. A nice feature (but I guess would at require microcontroller for sure) would be to make the power used by the vacuum cleaner variable based upon how much current is drawn from the outlet.
My first step would be to create something that turns on/off when the current passes a defined threshold (on if it's above, and off it's below).
In advance, thanks!
