I can get a blue-tooth speaker in my bathroom fan.

I can get a thermostat that I can talk to.

I can get a table saw that refuses to cut off my finger.

Can I get an air compressor that warns me before it starts up?

I'm up on the ladder, sneaking my probe into a ceiling junction box
and the damn compressor starts up. Really?

How about a little beep-beep-beep or a tone or better yet "Hi, this is your
air compressor. Is it OK if I start up?"

BOOM ... problem solved!
