I would like to replace a battery pack with a power supply. I have several Force Fx light savers. These are powered by 6 AA batteries concealed in the hilt.
I want to create a small power supply that will be enclosed in a wall mount for the light sabre, when the sober is on the wall mount the idea is that it will be mains powered.
I would also like to create a small circuit that detects if the power supply is mains or battery and switches out the sound fx when powered from the mains.
The question is, what sort of power supply would I required to replace the 6 AA batteries?
