Just found this link from reddit woodworking where a guy built his own wireless remote controller. I have a wireless remote controller I bought and it has met my every expectation.When I use it, what is always running through my mind is -- should I leave the dust collector (2 HP) running on the chance I'll need it within the next 15 minutes as it is the start-up of the collector that wears it and costs $$. Also, what is the appropriate time interval a dust collector should be left running? This same kind of question runs through my mind regarding my air compressor. Ingersoll Rand advises that the compressor should not come online (go from stop to start) more than 6 times an hour, yet when I use my sander it does so more than 6 times (I have a 7.5 with 80 gallon tank that was rated for 26 cfm continuous duty). I need to sit down and crunch some numbers, take some amperage readings, and determine what the sweet spot is for leaving a dust collector running vs. stopping it.For the more computer inclined: http://diyourfaceoff.com/diy-dust-collector-remote/
