I know very little about designing even simple circuits, but am hoping someone can point me in the right direction.
I am working as a sound engineer on a play, but my question has nothing to do with audio. It concerns lighting, but not regular theater lighting, which is why out lighting guy isn't able to help.
In our performance, we have a lamp on a table that one of the actors will turn on during the performance, but we want it to automatically turn off after a few seconds. The length of time the lamp should be illuminated isn't critical, but around 5 seconds should be about right.
We've identified a light bulb that gives us the effect we're looking for - it's a 12 volt automotive bulb.
It seems to me that we're looking for a simple circuit that when current is applied, immediately lets current through to the bulb, but when some form of timing device - perhaps a time-delay relay ? - then the circuit is broken.
Any thoughts? Simple is good, too
