How to make bells light-chime for Cathedral art exhibition?
My girlfreind is making some bell shaped sculptures out of string (seven in total) that are to be hung in the local cathedral, and she would like to make them 'Chime' by lighting up. I say she would like to make them do this, but as I'm slightly more practical (though not a great deal) I've been charged with the job. I've done some reaserch into variouse methods but these either seem unapropriate or are too technically demanding.
I've looked at DMX style theater light controllers- too expensive and bulky, and using a programable circuit board controller- over my head. Ideally, she would like a bell to light up for a second or so before dimming, and then have a different bell do likewise and so on. The pattern can be comlpetely random and does not need to represent a piece of music. I thought I may be able to do this with pendant lights and timer plugs, but the timer fragments on these represent fifteen minutes- too long for the lights to be on to read as being struck and chiming. Is there anyway to shorten these time fragments?
Would consider using lower voltage lights a transformer and some clever electronics, as I can solder. I just need some idiot-proof advice. I can PAT test it too before using so dont worry, I promise not to sue if I blow myself up.
