Hello everybody,
I am a sculptor based in London and in the process of making a sculpture that requires a vacuum cleaner to turn on and off at regular intervals coinciding directly with a pendulum.
I have been considering two possible options for this:
1. A timer: I can work out how long each swing takes and use as timer to activate and deactivate the vacuum. I've had a look at timed relay switches (and actually bought one) but my electronic knowledge is so minuscule that I've got the relay to work, but it requires an additional switch of somekind and I cant figure out what!
I like the idea of using this method as I'm hoping that control circuit can be hidden in the 'body' of the sculpture, keeping it looking as simple as possible.
2: a beam break or similar: I have been reading up about PIR's etc but as the pendulum is does not give of heat, a beam break would be most likely be better. The pendulum would break the beam at the bottom and trigger the vacuum to start which would be on timer. I've had a look for motion activated bathroom lights as I thought this might be a (relatively) simple adaption to make; instead of trigger a light, it'd trigger a vacuum. The only issue is that appear to only be PIR's that work on infrared, and the on time minimum is 30s or so which is way to long. (I'd probably need 5-7s max)
I'm hoping that someone can help as I've been scrabbling around desperately trying work it out using my (very very!) basic knowledge of electrical components and electronics. I've had a look through previous forum posts and have found things that might be similar, but I can't for the life of me figure it out!
I realise that this may be a bit of a pain but hopefully there's a relatively simple solution that a noob such as myself can build! Anyway, Any help would be greatly appreciated,
thanks
Simon
