I have a slightly unusual project I wonder if someone can help with. I need to customise a guitar to include 20 4.8v 3A torch batteries. They will be powered by 2 4.5V Alkaline batteries, the tricky bit is that i need the lights to flash on and off in groups of 4 or 5. Basically I think i am looking at having 4 or 5 loops of lights presumambly in serial, connected to 4 or 5 channels. What I am lacking is a simple controller to switch channels on a timer (once per second would be about right)
I think the controller itself should be relatively simple but I don't know how to design it. Can anyone email me a basic diagram and list of components i would require? The 2 principle considerations are that it would need to be basic as I am not an electrician, and secondly that it would be fairly compact as it needs to fit in a guitar.
Any help would be greatly appreciated!
