I have a built model tree-house ( about 1m high ) and it even has 16 small lights 4.5V ( 3xAA's ) placed inside the cabins and going up the staircase etc etc. Well, I am displaying it in an arts and crafts show in about 6 weeks, and I would like to fit a small circuit that will turn the lights on for say 1 minute, then off for say 5 minutes in an ongoing cycle.
The main issue is it needs to be low power... I bought a small board with a timing IC that I thought would work, it did, BUT I discovered that the battery to drive it ( small 12V ) dies very quickly ( few hours ), so I need something more simple to do this job, and would love some ideas / pointers. I am not a skilled, or even novice electronics hobbiest, the best I could claim is interested with the occasional dabble, but this time I do have a real project!
I look forward to any interest / ideas, Many thanks, Paul.
