Hello all,
I am brand new to circuits and wiring, but I have been given a task that requires me to learn some. I need to make a card box for my brother's wedding that looks like the TARDIS from Doctor Who (about 2 feet tall). Cards will be put in through an ajar door, and the card needs to trigger a switch that causes the light on top of the box to slowly strobe on and off while playing the sound of the TARDIS landing. It only needs to last approximately 10 seconds.
Preferable this will run off batteries, but I can deal with having to plug it in if necessary.
So far I have found this potentially for the sound effect. I have looked at both PIR sensors and Ultrasonic for the initial trigger, I'm not sure which is better (the cards might not be warm enough to trigger PIR?).
I have not been able to find a circuit that will slowly strobe a small bulb. The only restriction for the bulb is that it needs fit inside a cylinder 2 inches tall with a diameter of 1 inch.
Any ideas would be greatly appreciated. When it's finished I'll get pictures and video up to show how it worked!
PS The sound effect can be found here. And this is the TARDIS (for those sad people that don't know)
