content: I have a bandsaw in my workshop. I forget to turn it off and it damages blades and machinery. I wired the lamp to the bandsaw switch so the light would stay on. but the ambient light in the room and the direction of the lamp if turned away causes me to miss it when I walk out of the shop. I thought it may be smart to wire a sound producing instrument to the machine instead. But one that is not obnoxious. Does anyone have a simple idea?

content: Yeah not sure how this works. Do you just walk into your shop and switch all your saws on? It seems like a crazy scenario to me.You would be much more profitably occupied by changing your behavioural habits. Try turning it on immediately before making a cut, then flick it off as soon as you are finished. That’s what every other single person I’ve ever met does.

content: Let's say the shop is noisy and/or the bandsaw is unusually quiet. And that the job involves doing the same cut or cuts on multiple workpieces that arrive in a bin that's behind the saw operator. So you cut a part, put the part in the output buffer, turn around to get another part, turn back to the saw... lather rinse repeat. Maybe you need to walk over somewhere to get more parts. Do you turn the saw off after every part, only to turn it back on again in a few seconds?Safety first, I always say. But what's safe in some situations isn't in others. How about one of those red rotating (or nowadays LED strobe) beacons mounted up on top of the saw, on when the saw is on? That would be hard to ignore when leaving the room.

content: It already has a light, but would be nicer to have a light right next to the door, better if it senses every single machine and you see something is on before you leave (unless there is a machine which stays on, that doesn't go to the light)One way of implementing that would be with a current measurement in the main line of the shop, if there's something taking more than a fraction of an amp you will leave on at most in lights there's something else on.If there's nothing that stays on, just trip the breaker, or have a breaker for the machinery and trip it before leaving. It could have the light that indicates something is on.JS
